Great topic. I am a volunteer operator at W7ASC, the Amateur radio station at the Arizona Science Center. We have all kinds of equipment and computers to wow the kids with when they visit but by far

Well guys I found part of my problem. When I knew that I had to remove C5 I put two headers in there and soldered C5 to. That way if I ever had to retune the output of the U3S I could resolved C5 to

Hi Ken, for some reason I have 5vdc on the antenna connection. Now sure why? Any ideas? if I take my Fluke meter and go between the - terminal of the 5v input on the U3S and the antenna ground

Allen. It is a 4. Somehow in trouble shooting the receiver I have changed the frequency reading to another band. The instructions say that after turn on and seeing the display then select the band for

Better yet, buy Hans' QSX PA (which is available now). Then buy the QSX kit later without it (Hans promised this option for buying). Without even looking I can tell you it is a virtual certainty

Never did learn Morse from tapes, but I did end up memorizing the tapes ;/ In October 2017 after I got my license, decided it was time to learn. Learn CW Online http://lcwo.net has been a God send.

Spare time?

I was complaining on the Novice Rig Reflector about the lack of available VFO kits to drive old tube transmitters.  I love QRP and QRP rigs but I also have another life.  I love older ham tube gear.

Hi, Vince Google K7QO. He has a code course in mp3 audio form that you can download to your phone and listen to while taking your twice-daily walks like I did. BTW, I'm 72 and do maybe

It's all real CW to me, Bob. I copy and decode with my ears so the source is irrelevant. A significant percentage of those contest ops who are sailing along at 30wpm are perfectly capable

Vince, The ARRL web site also has a number of files of past practice sessions at all the different speeds. You could download the files for the speeds you want and then transfer them to an audio

Where do I find the building instructions in English? 72 Tnx George/W2BPI

Michael, I don't have anything recent. Here is one at 7PM Pacific Time a few years ago. I just meant these to show an example of what you can see if you have a computer and the software. Bob

Is this 40 meters? If so, I would love to see one after the entire US is dark. Michael N6MST

Let's see if this come through? I use DX Lab with DX Atlas to monitor RBN activity. It gives me a picture of what is happening kind of real time. But it only shows stations sending "CQ" or "TEST".

Typo: Instead of "492, ...518, and ...497", I meant "492, ...497, and ...518". Oops. -HF

Hello all... I recalibrated my U3S (now clocked with a Taitien TCXO) using the frequency setting of 26,999,984. My TXs nominally at 144,490,480, ...500, and ...520 were then decoded at ...492,

Vince, These are RECEIVE only sessions but are a good place to start. They have both fast and slow sessions. Bob Macklin K5MYJ Seattle, Wa. "Real Radios Glow In The Dark"

Michael, I cannot operate right now but I can listen. Do you know about the "Novice Rig Roundup"? NRR. They operate on the high end of 40M between 7100 and 7125. It would be nice to see some

I didn't realize they had practice sessions. I will check that out. Thank you Bob. 73 Vince N1VIN
