Exact time is set via menu 6.9 ... With an external receiver tune in WWV Then goto menu 6.9 and preset next time in advance of WWV time THEN sync to WWV via? QCX 'Exit' right push button, press and

Alan, I though of taking a video and slowing it down but...that just takes time away from building more radios. :) I'll check the synth on my home receiver tonight. So long as it works

The way I wrapped T1 was somewhat different than the way Hans described in his documentation. What I did was start with the large secondary and wrapped it. After getting to the end of the large

Just a silly aside. Aldis Lamp signalling ( morse by light flashing ) maximum speed is supposedly a mere 14wpm. I'm not going to calculate the duration of a dit at that speed, but the Progrock is

I've checked menu 4.9, it's set to 700hz as it should be. Now I'm thinking that the 20Mhz clock might be the problem - if there's no 20Mhz, perhaps that stops the sidetone from being generated? And

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
