Chris, I've never really bothered, I had a counter on it and that confirmed it worked. But I've just tried counting, blowed if I see more than 3 but they are just short flashes. 73 Alan G4ZFQ

About 6 of us in the local club are building the 20M version as a club project. All the kits arrived last week and we are now getting organized (trying to get organized anyway) to start working on

The menu item 6.1 Becon: On ? You also need to have the exact time set and wait for the frame to start. It should transmit on a even minute. Don't know how this is indicated on the QCX thou. In the

Robin, Although I do not have a QCX it looks possible just to remove one end of an inductor, unwind one turn and resolder to the top of the board. The unwound length will have only a very small

What a fun kit to build. Every thing follows your instructions to a T. I have it transmitting on 20m cw with a recorded CQ. What I don under stand is wspr. I have all the info set, but what do I do to

Hi Alan, I've taken your suggestion and done the factory reset but still the same issue. On power up, does the LED come on first then flash four times? Perhaps I'm just missing a flash. Hopefully the

In the alignment menus look at 8.5 that tells you how to align the frequency without a GPS. Jan

Hi Robin, Sadly I dont think I can help on this one. When I trimmed the number of turns on the inductors (L1, L2, L3 and L4) I decided through lack of time to avoid the cut-n-try approach in favour

Chris, If it really is a D then I've not seen it. Try a reset as in section 4.2 All I see is rapid flashes, so fast I'm never sure I've seen 4. But then I'm probably just slow.. The FOX will be

Hi Robin & the group, I see a number of people have allready responded with some good advice on this one but heres my 10p (10c) worth. I would go along with the idea that adding a small capacitor in

You need the PPS signal to calibrate the crystal frequencies. The serial data is for time and info only. The calibration takes a few seconds and you should see a new value that most probably don't end

Hi All, I just completed assembling a progrock that I'll use in a QRP receiver. The user manual states that on power up the LED should blink 4 times and go out. Mine blinks like a CW 'D' (one long

Greetings all;? So I put my QCX-20 on the air last night to check calibration. I am using my Yaesu FT-920 as my frequency standard. I noticed both TX/RX freq are a few kHz. I don’t

Hi all QCX firmware version 1.00e is released. You don't need to upgrade unless you particularly want/need one of these changes. Changes in this version: - Bug fix: stored message sending now sends

Hi Dave Have you checked for a short from IC3C pins 4, 10 to Ground? I agree, testing Clk2 when it is unconnected would be a good idea. 73 Hans G0UPL http://qrp-labs.com

Hi Dean It sounds to me that you probably fried IC4, the FST3253, which is the mixer (Quadrature Sampling Detector, a.k.a. Tayloe Detector). If that is blown, the op-amps would be just amplifying

Hi Yes, I can add that to the next firmware version - to only key in straight mode using the tip connection; then if a mono plug shorts the ring to ground, it would not cause a problem. I can add

Lets us know how the toroids go Keith. I got my kit last week? and just getting ready to start assembling on the weekend. I have printed the whole manual. 73 - Hew VA7HU
