QCX boots up, aligns, receives. With keyer set in straight, practice mode ON. Can use external keyer or built in keyer. Generates tone, decoder reads signals. Set practice mode to OFF. Attach dummy

Rick/DJ0IP Thank you very much for: (1) Taking the time to perform extensive research (2) Share this highly valuable information with the rest of us Mark Lunday, WD4ELG Greensboro, NC FM06be

Juan HK6J QRP is usually seen as 10 watts or less. QRPp is usually seen as 1 watt or less. Arv K7HKL _._

Tnx Andy, my QCX/20 comes out with 2,8 watts HK6J Juan Herrera Enviado desde mi iPhone

Mark's reply was very good.? I'd like to add a bit if I may. Asking if a matchbox (not tuner) has a lot of loss can only be answered with "it depends". All matchboxes have sweetspots (frequency and

Hi Juan, QRPp is transmitting with less than 1 watt. Andy

I have repaired a few. Be happy to take a look. -- Wes AE6ZM Sierra Vista, AZ

Hello, what does mean (QRPp)? Tnx Juan HK6J Juan Herrera Enviado desde mi iPhone

I'm certainly no expert, but I'll tell you my experience. I run QRPp whenever it's possible given summer QRN and poor propagation. I don't like the "listen and pounce" approach one bit, so I always

Success! I found my problem. Besides rewinding and remounting the T1, I found a cold solder joint on C1. Those two things fixed it and I made my first contact!? Thanks for all the help, Jim - K9DD

Thank you everyone for the replies and help! I was confused with the procedure. I will try Al's advice using CHU since I do not have a reference radio hooked up at the moment. Thanks again, OM's 73 de

Trueblue..? (IBMer?) ;) Anyhow.? There are many ways to look at this. LEts review the three rules: 1. For a bigger signal put the wire higher.? Altitude always helps. 2. If you cannot put the wire

It will be interesting to see the responses from others. Answers vary because there are many variables, as you know. And I echo Alan, and add “The best QRO station has…the biggest antenna with low

So, yes. That was my understanding of the logic.? I thought it must have been a trick question. (EME people seem to view this efficiency quite fanatically.)

Bob has a really good RX location and Beverages... The same amount. But QRO + losses is still more effective than QRP + the same losses. The most effective QRP station has the biggest antenna with low

Erik, Yes this is correct. BUT you cannot use the CQX to check itself. The actual RF output, frequency counter and generator relies on the 8.5 setting. Change the setting on 8.5 and it all moves, the

OK, so in these dismal periods of propagation, ~0.15W and an "antenna" that's merely a piece of wire strung up in the hallway with staples, what should show up on aprsinfo but an hour and twenty

Thanks for explaining that Jim, it's very helpful. Everything seems to point to T1 and a dodgy solder joint. I will report my results. I was not able to complete the fault finding tonight due to other

Piotr, My 40M QCX had the same symptoms. I did carefully check my solder work as recommended and also performed a reset. None of these steps made any improvement. I asked Hans for a new EPROM which he

Hi, Paul Your radio has 2 detectors working "in parallel", either one of which will do a good job of receiving signals. There are 2 detectors because by adding the detected signals 90 degrees out of
