The Radio Amateur’s Code
March 22nd, 2016 | 
Author: The Radio Amateur's Code
CONSIDERATE...He/[She] never knowingly operates in such a way as to lessen the pleasure of others.
LOYAL...He/[She] offers loyalty, encouragement and support to other amateurs, local clubs, the IARU Radio Society in his/[her] country, through which Amateur Radio in his/[her] country is represented nationally and internationally.
PROGRESSIVE...He/[She] keeps his/[her] station up to date. It is well-built and efficient. His/[Her] operating practice is above reproach.
FRIENDLY...He/[She] operates slowly and patiently when requested; offers friendly advice and counsel to beginners; kind assistance, cooperation and consideration for the interests of others. These are the marks of the amateur spirit.
BALANCED...Radio is a hobby, never interfering with duties owed to family, job, school or community.
PATRIOTIC...His/[Her] station and skills are always ready for service to country and community.
The original version of this was written in 1928, by Paul M Segal W9EEA, and it's been modified over the years as things change with the times. The core message remains the same though, as it's pretty much timeless.
The one trait that I want to touch upon today, is the "Balanced" one.
The Radio Amateur is:
BALANCED...Radio is a hobby, never interfering with duties owed to family, job, school or community.
Sometimes, I think we forget this one the most, and the evidence is not that hard to find. Take a wander on over to Facebook, or listen to a repeater and it's pretty obvious that some of us become seriously preoccupied or obsessed with such activities as NPOTA, contesting, DXing, county hunting, SOTA, etc.
Amateur Radio, on the whole, and these activities in particular are good and wholesome things. For instance, I'm certain that a lot of our wives, husbands and significant others would rather have us in the shack, yakking away on our radios than spending the month's mortgage money in bars,saloons, casinos or race tracks.
But it's easy to lose focus and become obsessed. Radio sport that involves chasing that elusive country, county, SOTA peak, NPOTA entity or whatever should never become the focus of our lives, or our reason for being. Just as purchasing that new rig, antenna, or piece of test equipment should never result in being unable to pay the mortgage, rent or put food on the table. It should also never result in the kid's college fund being raided.
Do you enter the shack on a Friday night for a contest, only to emerge late Sunday evening or early Monday morning? That's not good, my friends.
Even an essential thing can become bad, if you're not careful. Are you that someone who HAS to be at every civic function or training class? Even public service, as worthy and noble a cause as it is, should never become between you and your family. Before going out to respond to any disaster or emergency, the health and welfare of your loved ones should always be your top priority. If they're not taken care of, you don't go.
The bottom line is that there's more to life than Amateur Radio. In our quest to satisfy our passion, sometimes we forget that. Family, friends, loved ones and those relationships are way more important, and should always come before getting that high score, or working that 300th country or buying that newest, latest and greatest radio.
Always keep in the back of your mind that the greatest gift you can give your family is your time. If you're doing OK with that, then you're doing a good job with the "Balanced" part of The Radio Amateur's Code.

QRP - When you care to send the very least!
I had hoped for better results
As planned, I went and activated Morristown National Historical Park (HP28) for NPOTA. Things didn't turn out as well as I had hoped; but it was still a good time nonetheless.
I got to the park on time, right before Noon (1600 UTC). I allowed my TomTom GPS unit to bring me up to Jockey Hollow via a new route which I had never taken before. This brought me up through the Great Dismal Swamp, which is designated as a National Wildlife Refuge. It is truly a beautiful area and as I was driving through, I could see herons and egrets and all sorts of birds in the marshes. Seeing that the Great Dismal Swamp is designated as a National Wildlife Refuge, I was wondering why it's not listed as one of the NPOTA WR entities. A little Googling revealed that the Swamp is administered by the United States Fish and Wildlife Service and not the National Parks Service. That's a shame because that would be a really beautiful area to set up a portable operation from.
Anyway, I got to the Park and got set up, which by now, only takes me a few minutes. After so many lunch time QRP sessions, I could do this in my sleep, or with my eyes shut.
Since I was planning on operating some SSB in case there was a lack of activity, I brought along my big, heavy Werker deep cycle battery. I figured that this way, I could operate for an extended period of time at the 10 Watt SSB level if I needed to. And boy, did it turn out that I needed to!
The first thing I did after setting up was tune to around 14.061 MHz - the neighborhood of the QRP Watering Hole. I was shocked by what I heard - wall to wall CW signals! There was literally nowhere to sit where there wasn't a station calling "CQ TEST". I didn't realize that today was the RUDX, the Russian DX Contest - and boy, it filled the band!
I went on up to 17 Meters and heard some Europeans that were very loud. Knowing that meant the band was wide open, I easily found a clear spot at 18.082 MHz and proceeded to call "CQ NPOTA". The band was wide open, but as it turned out, there wasn't much if any activity. I worked K0IG right off the bat and then ...... nothing.
Not wanting to waste too much time, I got out of the Jeep and switched from the Buddistick to my 40 Meter Hamstick. I went down to 7.037 MHz, called CQ and was greeted by the normal NPOTA pileup. I was stoked and began to work station after station. The only bad thing was that the initial pileup lasted for only a few minutes, and then I began the monotonous routine of calling "CQ NPOTA" and waiting minutes in between answers.
Getting bored, I decided to give 20 Meters another try. Off came the Hamstick and up went the Buddistick. I called CQ for a bit and got a couple of QSO completed on 14.060 MHz, but it was tough. The stations calling me were loud, but their calls were being blanketed by even louder DX stations. Those guys had to be using mondo power. How much do they allow over in Europe, anyway?
Sitting there, disappointed as heck, I was ready to pack it in and head home a bit early. Then an inspiration occurred that maybe I should give 20 Meter SSB a whirl. Even though I'm not an avid fan of SSB, I decided to give it a shot. I was rewarded with a small run of about a dozen stations before that too, ended up petering out.
I had gone up to HP28 with a spiral notebook, thinking I would fill pages with call signs. After all, my outing to TR23 in January netted me over 80 QSOs. For some reason. I was thinking I would break that record easily. Just the opposite happened! I ended up with only 27 QSOs - but you know what? I discovered that a bad day of Amateur Radio is STILL better than a good day at work. So I'm a happy camper, anyway.
This only gives me more incentive to go back up to HP28 later this year, but this time throw a wire into a tree. I know that's kind of verboten, and on Facebook, someone actually related how they were asked to leave a park the other day for doing that. With that in mind, just before I left, I went to the visitor center and explained that I was an Amateur Radio operator and what NPOTA was (she knew what it was, by the way) and asked if there was any prohibition about wires in trees. She said as long as it was temporary, and would cause no damage and would not interfere with anyone else's visit, that they were OK with it.
So when I got back to the car, just for the heck of it, I attempted to launch a line over a limb just to see how it would go. 30 plus feet on the first try.
I'll be back, Jockey Hollow!

QRP - When you care to send the very least!
Weather forecast is looking good
The weather is looking good for Saturday for my planned expedition to Morristown National Historical Park (NPOTA HP28) this coming Saturday. Sunny with high temperatures in the upper 40s (9C) Hopefully, there will be no curve balls out of Left field that will preclude me from going.
The plan is to leave the house somewhere around 11:00 AM (1500 UTC) and be up there and on the air by around 12:00 Noon (1600 UTC). I plan on working 40, 20 and 17 Meters - CW around the QRP watering holes. I'll be packing some water and snacks and hope to stay for three or four hours. I am going to see if I can get the PAR END FEDZ 40/20/10 up in a tree in the parking lot. If not, I'll just rely on the Buddistick for 20 and 17 Meters and a Hamstick for 40 Meters.
Last Saturday, I went to the Cherryville hamfest out in Flemington, NJ which is run by the W2CRA, Cherryville Repeater Association. This was the very first hamfest that I ever went to as a newbie Ham back in 1979, and it's always held a special place for me. Unfortunately, over the years (and especially since the dawn of eBay) the Cherryville hamfest seemed to be on the down slope. Like a lot of hamfests, it suffered from poor attendance, lack of vendors, etc was plaguing it - and seemed to be spiraling towards its death knell.
Happily, between last year and this year, that trend seems to be reversed. Attendance is still nowhere near where it used to be, but it's growing. The number of vendors is still down (but again, growing), and for the most part the really bad junk is gone - and by junk I mean non-ham related garbage. I mean really, who wants to buy a roto-tiller at a hamfest? Sure there's still lots of non-Ham stuff to be seen, but it also seems there are more and more treasures to be found.
I purchased some new SO-239 chassis connectors as well as two old butterfly type variable capacitors that I got for five bucks. The capacitors have long stems on them, so they should be useful in my magnetic loop antenna project. I need to clean them up with some contact cleaner, but some initial testing seems to indicate that they are in the 200 pF range. KJI Electronics was there, and I purchased a Diamond antenna for my VHF/UHF handheld. What a difference when you buy the real brand and not a cheap knock-off!
Before I forget ........ I have a friend who has a "hardly used, very good condition" SGC-2020 QRP radio that he wants to sell. I am not privy to the price. But if you're interested, send an e-mail to [email protected] and I will forward it on to him. He's not looking for eBay type money, but he's not interested in getting taken, either.

KJI Electronics was there, and I purchased a Diamond antenna for my VHF/UHF handheld. What a difference when you buy the real brand and not a cheap knock-off!
Before I forget ........ I have a friend who has a "hardly used, very good condition" SGC-2020 QRP radio that he wants to sell. I am not privy to the price. But if you're interested, send an e-mail to [email protected] and I will forward it on to him. He's not looking for eBay type money, but he's not interested in getting taken, either.

A visit with a QRP contest station
160m Spring Stew Perry Contest - QRP style
I had the opportunity to visit with Paul Stroud AA4XX as he worked the early hours in the 160m Spring Stew Perry Contest. Paul is an avid CW operator dedicated to QRP and QRPp operations. When he works contests he often participates using the Knightlites club call WQ4RP (Note the QRP in the call). |

160m Top Band
160m (top band) is challenging due to the physical logistics of a suitable antenna. I had the opportunity to assist with a portion of raising the 160m vertical loop antenna at the "Excalibur antenna site" and installing the 24 elevated radials that help make this antenna so effective. There's a lot of wire in the ground system. The antenna site is located in the woods, off grid, and away from electrically noisy homes.Power to the remote shack is supplied by a quiet Honda 1kW generator operating a couple dozen feet from the shack. Due to the lower power requirements of QRP Paul can run the generator on eco-mode allowing its small fuel tank to provide 8 hours of operation between fill-ups.
Paul uses a Ten Tec Argonaut VI, running 5 watts output into the Excalibur 160m vertical loop. He uses N1MM+ logger software and a WinKeyer interfaced to the software. He also employs a SDR (software defined radio) feeding CWSkimmer signals across the band. An antenna splitter simultaneously feeds the SDR and the Argonaut. The SDR receiver is switched out during transmit by a DX Engineering RTR-1A Receive switch. His CW key is a N3ZN ZN-QRP model.
The N1MM+ logging software keeps track of which stations have already been worked and the CWSkimmer interface displays calling stations on the band being heard by his antenna.

| The remote QRP station setup for contesting |
In the Stew Perry contest the only information exchanged was grid squares. I'm still relatively new to CW and watching Paul casually copy grid squares sent at 30wpm was impressive. I would have had to ask the caller to re-send their grid squares 5 times but Paul makes it look easy.
Instructions for the newbie
Paul explained to me the in's and out's of operating in a contest. Speed and timing the openings were important, as was persistence. The integration of the software and receiving tools optimized his operating but experience and skill seems to be the biggest factors to success. I could have sat down there using the same tools but I would have been dumfounded with the logging controls and the speed the other stations were sending information. However, not all stations were sending at mach speed. When Paul worked a station sending at a slower or faster speed he would use the interface to Winkeyer to speed up or slow down the sending simply using the Page-up / Page-down keys. He would change frequency to a new station in the skimmer display by clicking on it.
Due to the limited amount of information exchanged during the contest most of the sending is accomplished via macros programmed into the contesting software. Paul rarely had to touch the CW key during the time I was there and his primary physical interaction with the radio seemed to be changing bandwidth or bandpass settings (he tends to keep bandwidth at 500Hz).

Why QRP?
This contest was not a QRP-only contest although there were multipliers for working QRP. There were plenty of big gun stations operating and the Reverse Beacon spots showed some of them with 56dB SNR reports pounding the ionosphere with their big amps.
The strongest signal spot last night for WQ4RP was 35db with the average at around 18dB. Paul has worked QRO in the past but the challenge of QRP operation is now in his blood. During a previous 160m CW contest this winter he and Dick Hayter N4HAY worked 3 stations in Hawaii with Excalibur which thrilled them given the current propagation on 160m. QRP adds a bit more challenge and those multi-thousand mile per watt contacts on the top band make it all the more special

Why contest?
As a new CW operator I'm still getting my feet wet and enjoying the process of improving my CW copy skills doing more ragchews than adding stations to the log or chasing DX. I casually contest with the SKCC weekend sprints and it can be fun to see how many stations I work but I'm not ready for real contesting.
During the time I observed, I could sense Paul's excitement seeing the propagation progress across the band and when a distant station in Russia was heard he looked forward to the challenge to getting that one in the log using QRP. He let the stations running big amps get their fill before jumping in. Ultimately he wasn't able to work that station but he later worked a GW3 station in Wales which was a first for him on 160m. The rewards of contesting seem to be in the accomplishment of something difficult and achieving something new. I can understand that.
What's next?
With summer coming on 160m will turn noisy from atmospheric static and the opportunities for top band contacts fewer. Attention will turn to other bands and challenges for a while. Maybe Paul will decide it's time to get that 40m Moxon back up on the tower as the sunspot cycle decreases this summer.
I enjoyed the opportunity to watch real CW contesting first hand. It is technically challenging and requires skills I do not yet possess and I look forward to progressing in my CW/QRP journey to the point where I can assist Paul in a contest.
That's all for now

I will have a BLT please
The BLT-Plus Balanced line QRP tuner
I was looking for a QRP tuner for the 1Watter 40m transceiver I am building that would work with both balanced feedline antennas as well as coax feedline. The traditional Z-Match tuner is quite efficient at tuning balanced line antennas and the built-in SWR bridge gives you an all-in-one tuner and SWR indicator without having to take a separate SWR meter along with its inherent mess of cabling a separate SWR meter. The BLT in the name stands for "Balanced Line Tuner".This tuner kit is available from the fine folks at Pacific Antenna.
 |
| The Kit as it comes out of the bag |
The kit comes with everything you need except for hookup wire and your soldering equipment. Instructions are downloaded from the qrpkits website.
Why use a z-match ?
Here are some advantages that the Z-match design offers:
- Matches balanced loads without the use of lossy baluns.
- Being a parallel resonant circuit, the Z-match can provide some band-pass filtering for your receiver and harmonic attenuation for your transmitter.
- A well-designed Z-match tuner has a high Q and is more efficient (less lossy) than other types of tuners.
- The fixed inductor simplifies construction (no taps or rollers needed).
The secret sauce
Matching balanced line fed antennas is sometimes problematic for a traditional balun and tuner as the antenna can present impedances that are far outside of the balun's design. The Z-Match uses a center tapped coil to keep the complex impedance balanced across the inductor (at least that's how I understand it). I have measured my Elecraft BL2 balun getting appreciably warm at QRP levels when connected to my doublet indicating loss I'd prefer to avoid. The Z-Match design supposedly results in less loss.
Built in SWR indicator
The BLT plus includes a Dan Tayloe N7VE LED SWR indicator which eliminates the need to carry a separate SWR meter. The concept is beautiful. The SWR bridge is switched into "Tune" mode and presents a 50 Ohm impedance to your transmitter while you are tuning so that you don't risk damaging sensitive home-brew finals. The LED lights when the SWR is too high and dims and then goes out as the match is made. It is simple and fast to use. The instructions for the bridge are not with the BLT instructions. Download them from this link.

Building
The kit is relatively easy to build with one tapped toroid to wind for the SWR bridge and one 3 winding toroid for the tuner. I faced a few issues that you might avoid:
- The kit is provided with really nice water slide decals that give it a commercial look (if you don't ruin them like I did). The instructions recommend applying a clear coat to the decals after they are applied. I used a Krylon matte finish clear coat which indicated it was fine for metals and plastics but it partially melted the decals and caused them to bubble. I'd suggest testing whatever you are going to clear coat them with first.
- Don't over tighten the plastic tuner shafts or you won't be able to slide the knobs on (yes I did).
- The binding posts have little plastic spacers that separate and it isn't obvious. If you install them and wonder how they don't ground themselves (like I did) you've done it wrong and will have to go back after it's together and try to remove them with all the wiring in place.
- The bolts for the binding posts are very soft metal and the nuts can strip them if you apply too much force (yep I did that too).
- The main toroid has three sets of windings and they overlap. Pay attention to the instructions about winding them all in the same manner (clockwise or counter clockwise) or you will have to rewind them (yep, I did that too).
- The 3 windings on the main toroid overlap so you won't be able to go back and verify your turns when doing the 2nd and 3rd winding so count carefully (ask me how I know).
- Temporarily attach the SWR bridge to the front panel to get the spacing correct to solder the LED leads.
My tuner toroid ended up being a bit messier than I'd like because I had to rewind it and my resulting leads aren't as short as they could be. I may go back and trim the leads to make it tidier but my least favorite part of winding toroids is heat stripping the insulated magnet wire so I'll probably leave it as is. Initial tests indicate it's working great.

Operation
- Connect your transmitter and antenna.
- Choose the appropriate switch in the back for coax or balanced line antenna (Up for coax, Down for balanced line).
- Start with the inductance switch on the back set to low-impedance (Low-Z) because it is the most efficient. It uses the 6 turn secondary rather than the 12.
- Switch the front switch to "Tune"
- Key the transmitter and be sure you are using 5 watts or less
- Turn the "Load" knob first until you see a dimming of the LED then the "Tune" knob to make it go out completely
- The knobs interact so you'll need to go back and forth between them to achieve best match
- If you can't get a good match switch the inductance switch on the back to "High Z" and try again
- Don't apply power too long at a time during tune because the 50 Ohm resistors are heating up in there during the Tune process
- When the LED goes out or gets very dim you have a very good match. Switch to "Operate" and enjoy a well matched antenna

Remarks
Qrpkits offers a great little kit that results in a commercial looking product. You end up with a small portable tuner plus SWR indicator that reduces the complexity of your portable operation. Pacific Antenna is very responsive to questions. I sent a question concerning the incorrect instructions I'd downloaded for the antenna bridge and James answered me the same day with a different link (included above).
So if you have a QRP radio that needs an antenna tuner I recommend this kit. It's well thought out and works well.
That's all for now
So lower your power and raise your expectations
