What about a CQ Call on the reverse beacon net.?http://reversebeacon.net/ They indicate your frequency. Martin

OK Chris. Sounds good. I can confirm that the X2 option on WSJT works very nicely with class D amplifiers I have tried it running in 'split' mode and it appears that it's just the bandwidth of the

Hi Stuart / Ken, A couple of considerations. If the PA is built with cosine shaping under the control of the U3, AN004 rather than the standalone variant. The U3 MCU may not like driving it's data

My guess it might have something to do with the data lines that are shared with the display. Perhaps when the voltage to the PA is cut off those lines go low and their state can't be changed by data

I have same kit built with relay board. Very happy with results. It will show corrupted screen like yours if I turn PA Amp off. I just don’t try to turn it off anymore.

Hi Andy, I did see OZ8PZ’s R5 modification on the QRP Labs website. ?I'm just curious why you decided to go with a 33K resistor instead of something closer to the parallel values of the original

Just for possible checking (by Hans ? )- screenshot of reported coordinates (in sync with QLG1 output) and correct calculated LOC (JN79EX) On CLOCK Kit display reported like JN79EW. Now is information

Hello Vernon, Will reply by direct mail, seen your e-mail now, I had missed it, sorry Monday, September 10, 2018 -- Best regards, Chris Wilson (2E0ILY)

Hello David, Thanks for the reply. I was trying to get my head around this but have worked it out via experimentation :) I wanted to use my TS-590 via the low power output from it's DRIVE socket.

Hi John, I'm not going to be able to measure current draw for a couple of days but in the qrp labs shop page re the ocxo Stig, OZ8PZ, said that as stock his ocxo drew 0.5A at start up, after putting a

Hi Chris. The simple answer is 137.55kHz. Since the output of the transmitter is 275.10 and it is divided by 2 However, I think your question may be a little more complex then initially read. Do you

Hi Ken, thank you for your reply, the mod i have done was to break the 12 volt supply to the Amp via the spare switch completely separate to the 5 volt supply. It should have been a simple mod and i

Rich Yes, I see from the manual that it does. But it is still not possible to calibrate without an accurate outside reference, or counter. (If Eric was using the correct connections and settings then

Hi, so nobody here with the same or similar experience with Clock unit LOC calculation/display accuracy? -dst-

Hi Stuart, need a bit more info from you but here goes; 1) what actually is 'the mod'? If you inserted a break in the 5V to PA pins, then are you sure you switched the correct pin off? (i.e PA pin and

Interesting views. My iron is at 280C I put the iron against the parts for 0.5-1 second and then apply very thin solder to the parts for max 0.5 seconds, not to the iron, and then remove the iron and

Hello group, i have completed the kit with the 5w HF PA all working ok. I have done the mod to be able to switch of the Amp off from the left top front switch. On power up with amp on all is ok but if

Hi Andy, I just finished assembling an OCXO kit and now testing and calibrating. ?Like others, I'm finding the heater is pulling WAY too much current when started cold so I need to swap out the stock

I would have thought the frequency counter would use the 20MHz crystal, so it would not be affected by changes to the 8.5 setting. Rich

Hello, I use solder Pb38 / Sn60 / Cu2, 0.56mm (0.23i), a 50W soldering station with 330 ° C (625 ° F). With that you can solder everything on the QCX. At higher temperatures, the tin will flow a bit
