My somewhat annual rant about power.

I got involved in another "discussion" on an Amateur Radio page on Facebook about QRP - again. The basic premise was that someone came on and mentioned that they finally made their first HF contact, after many months of trying with 5 Watts. Said person said that they " gave up on that for now" and that "A little more power was all I needed."  It turned out that our intrepid new HF'er was using a 40 Meter dipole at a height of 16 feet.  Immediately, a tsunami of comments followed, some good, some questionable.  The one that caught my eye was:

"40M is not a band real well known for QRP operation. In fact it is most known for success with QRO (at or near legal limit.) Same thing applies for most HF bands (except 30M & 60M as required by law) and except during really prime conditions (not much of that lately.)"

Wait ....... what?!?  To me, this is a red flag. You might just as well say, "The science is settled." Same reaction.

OK ....... first let's take care of some business.  I know what you're going to say, "QRP is not for beginners!"  Well, I do have to kind of agree with that, somewhat.  Maybe not all beginners. When your anxious to get that first HF QSO under your belt, I would also advocate for using as much "nominal" power as you have at your disposal. So yeah, it was a good idea for our newbie to tweak up the power.  I'll give you that.

So I answered the above comment with:

""40M is not a band real well known for QRP operation." ...... What? It most certainly is! In fact it's one of the two favorite bands of most QRPers."

Which got this response:

"Larry Makoski I know I haven't heard any lately.... When they turn it up to 100W+ no problem, maybe there's a hidden message there somewhere? What is your definition of QRP? Mine would be 5W or less."

OK - so here we go. "I know I haven't heard any lately". That's an odd statement to make. How would you know whether or not a signal you are hearing is a QRP or a QRO signal?  Bingo!  He had not heard any WEAK signals lately, so ergo - they all HAD to be QRO signals.

Weak signal = QRP and strong signal = QRO ........ got it?

No ....... I don't got it. So I responded:

"You haven't heard any lately? How would you know they're QRP? Because it's a weak signal? If that's your criteria, then you're dead wrong. Yes, QRP is 5 Watts or less on CW, 10 Watts or less on SSB. Signal strength has everything to do with propagation and antenna. Output power plays into it; but not as big a factor as the other two. I've worked 100 Watt stations that I've struggled to copy and I've worked 5 Watt stations that have blown the earbuds out of my ears. It's a whole bunch of factors that determine signal strength, not just raw power. And BTW, most serious QRPers will never even mention they're running low power. You've probably worked a bunch and never even knew it."

You would think more experienced Hams wouldn't jump to conclusions like this; but sadly they do. I guess that's part of this blog's missions - to educate ALL Hams that effective radio communications have more to do with antenna, propagation and band conditions than raw output power (alone). If QRP is not your "cup of tea" that's quite all right with me. No skin off my nose.  But even as a QRO op, if you want the best signal you can deliver, look at your antenna and band conditions first.  You needn't always empty your wallets for an amplifier. (Sorry, Elecraft!)

"Hearing crickets"

I guess that's a relatively new saying.  When someone says something that is so outrageous or so amazingly stupid that it deserves no response from anyone - it is often said that "All he heard was crickets".


Thanks to the 4 States QRP Group, soon we'll be hearing an entirely different kind of Cricket.  This kind of Cricket:


This kind of Cricket is an 80 Meter QRP transceiver designed by David Wayne Cripe NM0S. It was the OzarkCon Build Project this year.  As you can see from the photo, it's all through-hole parts - no SMD.  A great project for the first time builder.

It's based on the Pixie, but is much better than a Pixie.  No toroids to wind (you can see the coils etched into the board), and it also comes with an included straight key. However, if you want to use your favorite keyer and paddles, there's an input for that. The Cricket also uses MOSFETS for improved sensitivity and switching and uses a NJM2113D for the audio amp.

All the details and specs can be found at http://4sqrp.com/cricket.php

All proceeds go towards keeping OzarkCon a viable yearly event.  QRPers helping other QRPers - what's better than that?

In other news ............


"Morsum Magnificat" was a great little periodical produced by Zyg Nilski G3OKD, devoted to Morse telegraphy and those who love it. I was a subscriber, until the publication ceased in 2004.  Some (a lot) of issues are now available for downloads as .pdf files.  You can go here
http://www.n7cfo.com/tgph/Dwnlds/mm/mm.htm to download.   "Morsum Magnificat" was really a niche publication. You really have to have an interest in Morse Code telegraphy and its history to appreciate it. Thanks to N7CFO for making these available to us!

The weekend

Saturday was a normal, busy Saturday and it was cool with on and off rain. As such, that forced me to operate indoors for QRPTTF - and in a way that was a blessing. As it turned out, the bands were so dismal, that had I went out and traveled to a river and gone through the whole outdoor setup procedure, I would have been bitterly disappointed.  Somehow, making only four contacts isn't as disappointing when you don't have to brave the elements and the added work of setting up a portable station in the rain.

I could not believe the conditions on 20 Meters!  I heard stations, but only to the degree that I knew they that someone was there. Signals were so weak and into the ESP realm, that I was not able to copy any call signs.  I knew Morse Code was being sent; but that was about it.

40 Meters yielded my four QSOs.  I worked North Carolina, Ontario and Maine. There was one station (call sign withheld as I can't remember it! LOL!) that was frustratingly loud that I called and called and called ....... only to get "CQ TTF" as an answer for my effort. I finally gave up, figuring that he was either in a high ambient noise location, or that once again, propagation was not reciprocal.

The bad thing (or maybe it's a good thing?) about being a home station is that when the bands are dismal you can trot off and do other things, like chores and stuff. If I were a field station, I would have stuck it out longer because of the effort of putting a portable station on the air. I think the frustration level would have been markedly higher, though, as you look for a return on your expended effort.

In other things, I would be remiss if I did not mention the passing of Jerry Haigwood W5JH on April 21st.  I read of Jerry's passing via an e-mail to 4 States QRP Group (of which I am a member) by Terry WA0ITP.  While I did not know Jerry very well on a personal basis, I have worked him numerous times on the air.  In addition, Jerry was the driving force behind the AZ ScQRpions Black Widow and Mini Black Widow paddles.  I still have my Black Widow paddles and at one time I did own a set of the Mini Black Widow paddles attached to my PFR3A.  Both were/are excellent paddles and are a testament to Jerry's machining skills.


RIP, Jerry - you will be missed.

Lastly, I finally had the opportunity to sit down and play with something that was sent to me by Richard, G3CWI, owner of SOTABEAMS.  A few months ago, Rich graciously sent me a WSPRLITE, to play with and evaluate. The WSPRLITE is a small WSPR transmitter beacon, if you will, that you can use to test your antennas.


I hadn't the time, up until now, to give it the attention it deserves. Mind you, it's very easy to use - as easy as falling off a log - but as John Lennon wrote in a song, "Life is what happens while your busy making other plans."  I don't want to give the impression that I put off getting this little beauty on the air due to it being a difficult process. Nothing could be farther from the truth!  It's just that things (obligations, chores, colds) always seemed to get in the way each time I had planned to get it up and running.

Well, last night I got it up and running within a few minutes and got results almost immediately!  This lil' guy is way cool and I want to play with it for a few more evenings this week and then I want to let it run for a few hours in the daytime before I let you know what my impressions are.  But so far, it's a very neat tool to have, especially if you have more than one HF antenna and you want to see how they stack up against each other.

I hate to keep you hanging; but that's all I'm going to say about it for now.  The WSPRLITE will deserve it's own post to properly give it the evaluation it deserves - and you can look for that either next Saturday night or Sunday.

Filters

The last few Field Days, the South Plainfield Amateur Radio Club has been plagued by that perennial old bug-a-boo ........ stations interfering with each other.  Even QRP transmitters at close proximity can wreak havoc on each other! This year, I intend to do something about it. Since we typically run only two HF transmitters, I was thinking of building a set of these K4VX filters.

I've spoken with my good friend Bob W3BBO about this in the past, and he put the bug in my ear about using coaxial stub filters, instead. He has some experience using them and he told me they worked well for him.

I did some Googling and searching of the ARRL Web site last night and found this:

http://www.k1ttt.net/technote/k2trstub.html as well as this YouTube video:


As I'm going to be replacing the coax out to the Butternut as soon as the weather cooperates, I'll have a useful purpose for the old coax, instead of just tossing it.  It would end up being a lot cheaper than purchasing toroids and capacitors and enclosures and antenna sockets needed for the K4VX filters. All I need for the stub filters would be some PL259s (which I have) and a few T-connectors which I can get at a local hamfest.

If they don't work as well as I'm hoping, then maybe a combination of the K4VX filters along with the stubs can be used next year.  But it's already mid-April and time is growing short. Field Day will be here before you know it.  And even just the stub filters will be better than the nothing we've been using.

QRPTTF this weekend

This coming Saturday, the 2017 "Summer" Outdoor QRP Season begins with QRP To The Field. This event, put together and sponsored by Paul NA5N is one that I always look forward to. Sometimes, I even get to participate!

The extended weather forecast for the day is still somewhat ...... meh.

Overall, an overcast day with temperatures reaching a high of about 64F (18C).  The chances for showers increase as the afternoon rolls on.  The weather that day will be a big factor.

This year, the theme of the event is "A River Runs Through It".  The idea is to get out and operate from the nearby vicinity of a river, creek, stream, brook or what have you.  There are various possibilities around here ...... depending.  "Depending on what?", you may be asking.

Depending on ease of access, location, and name of said body of water.  The name of the estuary is part of the exchange.  I can go a bit farther from home to a nice park and have "Raritan" as part of the exchange; or I can stick close to home and have "Bound Brook" as part of the exchange. Obviously, the name of the river is a heckuva lot shorter than the name of the brook.

This might be one time that I may be sorely tempted to load a "canned" exchange into one of the KX3's memories, so I don't have to pound out "Bound Brook" all day long. I don't like doing that, as for me, that seems a bit too "automatic" for my tastes.  I know, I know ....... all the die hard contesters do that with their N1MM logging program and all they have to do is hit the F1 key all day long and make a ton of contacts to take the top places.  I'm old school.  I like making the exchange by myself and doing it the "old way". Of course, that's another reason that I rarely ever get beyond the middle of the contest pack.

The other factor, as mentioned before, is the weather. If it really looks like rain, I'll be tempted to stick closer to home.  If it's a gray day; but seems like it will most likely stay dry, I might be more inclined to go to the park farther away from home.

Hopefully, nothing will come out of Left Field (as it so often does) to make all the above a moot point - and for all intent and purpose ..... spoil the day.

Good Friday 2017


From noon onward, darkness came over the whole land until three in the afternoon.
 And about three o’clock Jesus cried out in a loud voice, “Eli, Eli, lema sabachthani?" which means, “My God, my God, why have you forsaken me?”

 Some of the bystanders who heard it said, “This one is calling for Elijah.”
Immediately one of them ran to get a sponge; he soaked it in wine, and putting it on a reed, gave it to him to drink. But the rest said, “Wait, let us see if Elijah comes to save him.”

 But Jesus cried out again in a loud voice, and gave up his spirit.
 And behold, the veil of the sanctuary was torn in two from top to bottom. The earth quaked, rocks were split, tombs were opened, and the bodies of many saints who had fallen asleep were raised.
And coming forth from their tombs after his resurrection, they entered the holy city and appeared to many.

The centurion and the men with him who were keeping watch over Jesus feared greatly when they saw the earthquake and all that was happening, and they said, “Truly, this was the Son of God!"

A Blessed Good Friday to all de Larry W2LJ

Plans

"The best-laid plans of mice and men often go awry."

Ain't that the truth?!?

I am taking tomorrow, Good Friday, off from work.  Tonight, with the Mass of the Lord's Supper, we Catholics enter into the holiest time of our year - The Sacred Triduum.  There will be a lot of time spent between now and Easter Sunday in prayer, remembrance and commemoration.

But there will be time for other stuff, too.  Namely, mowing the lawn for the first time in 2017.  I am hoping to get that done tomorrow. IF the lawn mover starts without a hitch.  The first time starting it up in the Spring is always dicey.  I always make sure to run the gas tank out in Autumn before stowing it away, and always put in fresh gasoline ....... but, you know.  So if you're so inclined, please say a little prayer tonight that W2LJ's mower will start tomorrow - OK?    :-)

If I get that done tomorrow then on Saturday, I plan to run the new RG213 that I bought from DX Engineering last Summer, to the Butternut. (You were wondering when I was going to get to Amateur Radio, weren't you?)

Now's a great time as it will not be freezing outside and the new "greenery" (weeds) hasn't begun to grow yet.  It's a 150 foot run from HF9V along the back fence, along the side fence and house into the basement.  I'll need to go to the hardware store to pick up a small amount of plumber's putty.  When I seal my coax connections, I put down a layer of electrical tape, then some plumber's putty, and then another layer of electrical tape.  The plumber's putty works just as well as Coax-Seal (TM), but it comes off a lot more easily and cleanly when you want it to.

The coax run that is currently there is probably fine, but it's almost 16 years old now and I think I may have nicked (but not punctured) the outer jacket with the lawn mower a time or two. While I'm at the hardware store I need to find something that I can use to elevate the coax a few inches to a foot above the ground, so that I don't nick the new stuff. Some kind of heavy duty garden stake - or something like that. Once I get to the side fence, which is a chain link fence, all I do is cable tie the coax to the top cross posts.  That keeps it completely off the ground.

Once I get that done, I think I'll need to order another bit of RG213 to replace the feed line to the W3EDP antenna.  That could use it, too.

Tough going

As planned, I did participate in the SKCC 150th Sprint last evening, for about 90 minutes of the two hours. I must say that from the beginning, my fist was rather lousy. It's one thing when your fist is lousy and you're blissfully unaware. It's altogether another thing when your fist is lousy and you're wincing as you make mistakes! It's strange to be looking at your hand while you're sending CW, making a mistake and thinking, "Why did you just do that?", as if your arm and hand belonged to someone else.

Thanks to all who hung with me for that barbaric assault on your ears - I deeply apologize.  That was the end result of using only a keyer and paddles or a bug for the last however. I do have to admit that as the evening went on, and I got more comfortable, my fist improved ........ marginally. I found out that I got better if I pounded the brass with my eyes closed, and relied solely on concentrating on the sound.

I must have been doing something right, though, because after 90 minutes of NAQCC Sprint, my wrist, hand and elbow suffered no discomfort at all. And people DID copy me ........ I did not get many "?'s", so again, I must have been doing something right. And the Reverse Beacon Network was able to copy my 14/15 WPM CQs, so I guess I wasn't as bad as I thought.  I AM my own worst critic!


I don't have my log in front of me; but I think I walked away with 18 QSOs - scattered across 20, 40 and 80 Meters.  40 Meters seemed once again to be the money band, yielding the most contacts. My meager effort was a lot of fun and brought back fond memories of when I participated in these sprints on a regular basis.  I'm now kind of interested in doing that again.  Not only will it help to fatten up my log book, but it will also keep me in regular practice on the straight key.

Last night, I used my LTA SKCC Straight Key, which is a nice enough key.


I keep on telling my buddy, Bill Koeth W2WK that I want to buy one of his straight keys.  Bill is a machinist with amazing talent and he produces straight keys that feel great and work marvelously and they're beautiful to look at, too!  I've test flown a few prototypes for him and want to add one of his production models to my bench. I think using one of his straight keys would be a further enticement for entering these NAQCC Sprints on a regular basis.

The other thing I noticed, quite happily, is that there seemed to be no increase in the ambient RF noise level at my QTH.  A neighbor two doors down just installed solar panels on his roof.  I've been told that with some installations, when the inverters kick in, there can be plenty of RF hash.  That was not the case last night; but I'll have to check this weekend during the daylight hours to make sure there's not a problem. Can you imagine going to your neighbor and saying, "Hey, I hate to tell you; but your brand new solar panels are wiping out radio reception at my house." THAT would go over like the proverbial lead balloon!

Special NAQCC Sprint tomorrow night

Tomorrow night, April 11th ( The morning of April 12th for those of you not bothered by UTC conversions), will be the 150th NAQCC Monthly Sprint.  That's 12 and a half years of monthly NAQCC Sprints now - since the club was formed.  In honor of this momentous occasion, the leadership of the NAQCC has planned something special.  Rather than try and go into my own details, I'll post the email announcement here:

On Tuesday evening, April 11 (4/12 UTC), we will have our landmark 150th regular monthly sprint. We want to celebrate this event by giving away a prize worth $150 to one member-participant! But there is a catch, we will only have a prize drawing if we get at least 150 submitted logs. You don’t have to be an experienced contester or a high speed CW operator to participate. Just get on the air, make at least 1 sprint QSO, and submit your log, and you will be eligible for the prize drawing. So mark your calendar and get ready!

EDT - 8:30-10:30PM, CDT - 7:30-9:30PM, MDT - 6:30-8:30PM, PDT - 5:30-7:30PM), which translates as Wednesday, April 12th, 0030 to 0230Z in all cases.

For all the "official" information, please go to:

http://naqcc.info/sprint/sprint201704.html

There you will find all the details as to time, frequencies and other important information.

This is a monthly event that caters to the CW veteran, the CW newcomer, straight key and bug fans. All are welcome to participate (this includes QRO); but you must use QRP power levels to compete for awards.

If you've been hesitant to join in our sprints because you hear other sprints running at breakneck speeds, have no fear. Our sprints are geared to the newcomer to CW and/or contesting. Virtually everyone including the many veteran contesters who regularly enter our sprints will slow down to YOUR speed to help you make your contacts.

If you are not already a member of NAQCC... membership is FREE! Now is your chance to join the largest QRP CW Club in the world!! We currently have 7100+ members in: All 50 States - 9 VE Provinces - 100 Countries. Sign up on the NAQCC website today (http://naqcc.info/) and receive a handsome certificate, with your membership number on it, which is good for life.

Come join us and have a real good time!

Admittedly, I have not participated in one of these in a long time. Between various commitments, I have either not been home Tuesday or Wednesday evenings; or I have been too pooped to pop from a long day's work. But I am going to try and participate for at least the first 90 minutes tomorrow night.  I'm not eligible for the prize as I'm quasi-NAQCC staff, but I can help drive the number of log entries up.

Ham Cram Results

Let's just say I was expecting and hoping for better results and leave it at that.  I drove home Saturday afternoon disappointed and a bit depressed.  It's hard on the instructors when candidates fail to pass the license exam. In my case, I immediately wonder, "What more could I have done?"  My personal problem is that, since I love Amateur Radio so much, I assume that every one in the class wants their license as badly as I wanted mine. So when they fail, I tend to internalize the blame.

But there was a clear division between the two camps. There were the people who wanted their license and actually studied the material diligently and there were the others who may have cracked open the license manual once or twice, if at all.  Listening to some of the comments from the folks who didn't pass, I was surprised at how little they applied themselves.

Let's face it, the Technician Class license exam is not the hardest exam in the world, but you DO have to study and you DO have to want it. Going to class because your good friend talked you into it; or because your supervisor thinks it would be a good thing to have a license is not good enough.  There has to be some personal motivation driving the effort.  As my RACES Bureau Chief said to me as we were leaving the building, "Just remember Lar, you can lead a horse to water; but you can't make him drink".  He's 1000% correct, but maybe there's more we can do to make drinking more enticing.

So where do we go from here?  While I am still wary of the Ham Cram process, I am willing to give it another shot.  I still think the full blown eight week class concept works better, but I do realize that less than perfectly motivated people are busy and have lives, and are not willing to give up that much time from their busy schedules.  I think with a couple of tweaks, the Ham Cram route can be a successful one.

Two changes in particular that I would like to make:

1) Ahead of the next "home study cycle", I would like an accurate head count of all the participants.  I would like to order their ARRL license manuals ahead of time and have a meeting with the candidates BEFORE the front cover of the manual is even opened.  I would like to take that opportunity to hand them their manuals, study guides and point blank tell them, "If you fail to study over the next month, or wait until the last minute to study, past experience indicates that you will not pass the exam."  I think it needs to be impressed upon the candidates how important the home study portion of this process is; and that without it, there's really no point in continuing on.  It would also be an excellent opportunity for Marv and I to introduce ourselves and give the students our contact information - so if they have any difficulty whatsoever, they know there's someone they can reach out to for help.

At that same meeting, there's an excellent video on Amateur Radio that we use for the first session of our eight week class sessions, that I would like to show. It comes in two versions, one 30 minutes long, the other an hour. Both go into a lot of the "fun" aspects of the hobby.  For those who are getting a license just for CERT and EMCOMM purposes, if they see the fun they can have once they're licensed, I'm willing to bet that it might be easier to get them to take a good, long drink.

I know that time is precious, but between handing out the manuals and study guides and then giving a little pep talk and then showing the video, we can keep that introductory meeting to less than 90 minutes.  I am coming to believe that this may be a crucial step in the process. If you're not willing to come to a meeting to get your manual and get a little pre-home study guidance, there isn't really a point with continuing on, is there?

2) A change of the Ham Cram review material. We used the W9PE Power Point last Saturday.  While it is complete and comprehensive and very good, I think it is more geared to the prospective Ham who is into getting a license for the hobby aspect of it.  I was given a Power Point produced by Alan Wolke W2AEW of YouTube Ham Radio videos fame.  His presentation is ideal for presenting to those who are coming to the Amateur Radio world from the First Responder world.  It is more visually appealing with lots of graphics; and as a result, I think it will be more successful.

I think if we make these two changes, our next Ham Cram venture will be more successful.  Now all I have to do is pitch this to the "Powers That Be".

I've never worked either of these ........

Midway and Kure Islands are Now Deleted DXCC Entities
03/31/2017

Midway and Kure Islands have been placed on the list of DXCC deleted entities, effective August 26, 2016. This came about as an unintended consequence of action last summer by then-President Barack Obama that expanded the Papahānaumokuākea Marine National Monument to include the northwestern Hawaiian Islands west of Ni’ihau Island, making it the largest contiguous protected conservation area under the US flag.

Midway (KH4) had qualified for DXCC status by virtue of its being governed by a separate administration. Because it is now under the administration of Papahānaumokuākea Marine National Monument, however, it becomes a deleted entity. Approximately 50 people live on Midway, including US Fish and Wildlife Service staffers and contractors. The Battle of Midway, a turning point in the Allied World War II Pacific Campaign, took place in June 1942.

Now uninhabited, Kure Island (KH7K), a part of Hawaii, is separated from the rest of the state by Midway; because of that, it qualified for DXCC status under Section II, 2 (b) (iii) of the DXCC Rules — separation from its “parent” Hawaii. Midway Island’s change in DXCC status in turn made Kure Island no longer eligible for DXCC status, since Kure no longer is separated from the rest of Hawaii by intervening land or islands that are part of another DXCC entity.

Kure Island once was home to a US Coast Guard LORAN station, remnants of which are still evident. It has been a state wildlife sanctuary since 1981.



The relevant parts of Section II of the DXCC Rules follow:

A Geographic Separation Entity may result when a single Political Entity is physically separated into two or more parts. The part of such a Political Entity that contains the capital city is considered the Parent for tests under these criteria. One or more of the remaining parts resulting from the separation may then qualify for separate status as a DXCC Entity if they satisfy paragraph a) or b) of the Geographic Separation Criteria, as follows.

b) Island Areas (Separation by Water):

A new entity results in the case of an island under any of the following conditions:

iii) The island is separated from its Parent by intervening land or islands that are part of another DXCC entity, such that a line drawn along a great circle in any direction, from any part of the island, does not touch the Parent before touching the intervening DXCC entity. There is no minimum separation distance for the first island entity created under this rule. Additional island entities may be created under this rule, provided that they are similarly separated from the Parent by a different DXCC entity and separated from any other islands associated with the Parent by at least 800 km.

Neither Midway nor Kure was able to be activated without prior permission and only for a planned DXpedition. Only contacts made on August 25, 2016, or earlier will count for these two entities.

Product reviews

I have two product reviews to do, from two kind Amateur Radio vendors who sent me some "cool stuff" to try out. Many. many thanks to hamshop.cz and SOTABEAMS for thinking highly enough of me to do some product testing.

I am going to do one review tonight and another after next weekend.  I have played with both products and both are superb; and I want to give each its due, so tonight, I will talk about hamshop.cz's Mini Iambic Mini Paddles, which I received first


I received these paddles a couple of months ago - soon after their availability was announced. They looked interesting to me and I had even mentioned on this blog that I would have liked to purchase a set.  Not long after that, a sample arrived in the mailbox. Thank you, hamshop.cz !!!

These are constructed from parts printed out from a 3D printer if I am not mistaken.  They are light in weight and are ideal for QRP portable ops, whether that be SOTA, POTA, or just a trip to your backyard, if that's what you have in mind.



One might think that something that came out of a 3D printer would be cheap or shoddy and I have to tell you honestly, that nothing could be farther from the truth.  I have played with these paddles for a while now and I have to tell you that they compare VERY favorably with my Palm Pico paddles. They are roughly the same size, but the hamshop.cz's iteration are a bit lighter and also a tiny bit larger. They use a magnetic return for a very smooth feel and a very positive return.The tension can be adjusted by tightening or loosening the big screw at the top and lever spacing can be adjusted by two tiny set screws by each paddle at the front of the housing.

These first run paddles came without a cable and I had to wire them up myself, but that was not a big issue.  I see on the hamshop.cz website that the paddles now come with a cable for the circuit board pin configuration that they use as a connector.


So, how do they work?  Very well actually! I have been using them on the KX3 and they have been a joy to use. As I mentioned, they are smooth and have a good feel to them. The positive return makes sure the paddles always return to "home" position reliably, so there is no issue with getting stuck sending unintentional strings of dits or dahs. I have sent at speeds from about 13 WPM to 25 WPM with no fumbling or mistakes due to the equipment. Any mistakes originated from the "gray matter between the ears".

They are ideal for portable ops as they are a breeze to carry in a backpack and are so light that you can hold them in your hand all day and send Morse for hours without getting tired.  I see hamshop.cz now supplies them with magnets on the base so that you can stick these to something if you'd rather not hand hold them for any length of time.

The price is a selling point, too. Currently, a set of these paddles go for 25 Euros, which is about $27 US Dollars. Compare that to the Palm Pico Paddles, which go for about $116.  I know, I know - this is kind of like comparing apples to oranges.

Would I give up my Pico Paddles?  No, not at all. When you compare the two, the craftsmanship and the materials used in the Palm paddles justify their cost.  But for $27, I think the hamshop.cz paddles are a bargain!  The operability, size and weight compare favorably to the more sophisticated Pico paddles, but the price is a clear winner.  If you're on a tight budget, you can have a set of really good miniature paddles for a very reasonable price. And, if you should have an accident and damage them; or even be unlucky enough to lose them, there's no heart attack factor involved - you just order another set!

Great news

for QRPers with REALLY long wire antennas:

http://cqnewsroom.blogspot.com/2017/03/flash-fcc-approves-new-mflf-ham-bands.html?spref=fb

The FCC has authorized two new bands for experimentation. 2,200 Meter (Yes, that's right - 2200 Meters) and 630 Meters.  Can you imagine having enough property to build a true 1/2 wave dipole?

2200 Meters will be limited to 1 Watt EIRP and 630 Meters to 5 Watts EIRP.

There are lots of rules to adhere to because "we" will be secondary on these bands, as they are used primarily by Electric Utility companies for controlling the power grid.

Click on the link above for more information.

ALSO ............ there's a new "NA5N-type" fun QRP Sprint debuting today/tonight (depending on where you live).

It's called the "Sasquatch Stomp" and it's sponsored by the Pacific Northwest QRP Group.

Here's "Da Rulz": https://sites.google.com/site/pnwqrpgroup/sasquatch-stomp

My official Sasquatch Stomp Badge

Tonight is our monthly radio club meeting, so I doubt I'll get much time to participate, but it looks fun, in the same vein as the "Zombie Shuffle".
