Nino, Sorry that it still doesn't work properly. My suggestion is to find someone else (local ham - in your local club, maybe) to look at it. A fresh approach may turn something up. Good luck! -- 73,

About an inch of attenuation. I pick up the signal with a loop close to the dummy load. I said I was a newbie ;)? Not very scientific!

How much attenuation between the TX and the TinySA?? Looks like TinySA input overload. -- Allison ------------------ Post online only, direct email will go to a bit bucket.

Hi all, I have measured the harmonics of my QMX high band where I have sacrificed 11M for 30M. As I'm a newbie on tinySA I want to ask the experts (you) if the screenshots I'm linking to below are

Thank you sir. Your support and patience is greatly appreciated. I am going to trace everything back using the schematic and resolder. I got in a hurry close to end. Going to take my time and triple

John,? that is great news.? POTA is super popular.? I have been in touch with?Allen for some of his activations.? Recently I ran into him running a frequencyin the CWops CWTs and doing very

I didn't get to the reinstall yesterday but should have it done this week, hopefully surgery will be a success! I did receive the TO-92 hat heatsinks; they arrived quickly. They're not so great, but

Hi Peter, Restoration of balanced signals into IC5 pretty much confirms it was damaged to some degree. Put in a new chip and check for balanced signals at both the inputs and outputs of IC5 before

Hi Giuseppe, It is great to hear of your success using the QCX Mini on 6 meters. I would like to know if you have any advice or comments about how you were able to wind the toroids and what other

Mike, Any screenshot of Drain waveform yet, it would be most interesting. Also output on dummy load. 73 Ross

Pretty much what I tell my customers.? I'm an aircraft mechanic as a day job.? Someone says, "my airplane won't start, when will it be ready?" and all I can tell them is, "I'll let you know when it

Well Hello, Charles, I didn't expect to hear from one of my advisers from CWA. I hope you are well. I've been hunting pota activators and often make contact with Allen from our class. CW has become a

Nino, if you measure the voltage on the control board connector, at the point S on below to ground on one of the connectors,?you should see: No buttons pressed 3.3v left button? pressed 2.0v right

Hi Daniel Thanks for your information but I can't still find the fault. I have very carefully checked all connections of the control board and performed an accurate continuity test and all is fine.

Hans, thanks for the update / reply. Certainly understood about the long hours - I can hardly imagine what your daily routine must be like! The CW glitches aren't much of a bother to me, as I use a

John. Great to hear you are doing a QRP Labs project, and I hope you have great successwith the 6m beacon. I have just finished a QMX Rev1 kit and go it on the air late last week.? These kits

Hello, I have a similar experience (kit dispatched on 7th December from QRP Labs). Probably the lot of BS170's delivered in the end of 2023 happens to have lower threshold voltage. The output depends

Saaaaaay ! That's RIGHT!! 72 / 73, Bill. N4QA/4 in OKI; formerly WB4HIO and, before that, WN4BJC in 1965.

I really welcome the prioritisation on the keying glitches and AGC Hans, as the former means I tend not to use my QMX currently. I know you will resolve them, and from my point of view I will then

Hello, Chris, it was one of the single-turn wires not soldered properly. Continuity test with a multimeter does not show anything except if it is the first winding being soldered, that's why the
