Hello Hans, Thank you for the quick response.? The reason for my question is that I have a poor antenna set up here and the input level indicator was down below 20db.? I do know it is that antenna

I liked the idea of building my QDX for 9v as I thought the occasional use off a lower voltage battery and still maintain 5W would be nice. Plus 'more efficient' sounded good to me, too, and I also

Buck/boost convertors are cheap on eBay and elsewhere. Those who want to stick to a 12 volt supply might pick up a 12-to-9-volt buck converter and put it in-line with their power cable. It’d waste a

Hello Evan I did not write it in the manual :-D If you set it too high, it will be obvious on the waterfall display which will look thoroughly awful. It essentially just multiplies the received

Hans, I apologize if I missed it in the manual, but can you tell me the valid range for the Audio Gain setting? 73 Evan AC9TU

I also like to do handicrafts and have decided on a multiband QCX + in the original housing. It works, but is still being refined. Short info : Bands 7-30MHz C amplifier with RD16HHF1 (around 8W at

Hi Andrew It's hard to say. I think running WSPR on a 100% cycle - for example setting up WSJT-X to cycle through 80-40-30-20, may be pushing things a bit too hard. The thing is not 100% efficient and

Simon, I'd guess so. I use 26MHz TCXOs in most of my QRPLabs gear including Progrock. 73 Alan G4ZFQ

Is the progrock happy to run with the 25Mhz TXCO module in the si5351 synth?? I couldn't find anything in the progrock manuals on this other than a reference to how to manually program the reference

Thank you Curt and Ian for your input.? As it turns out, when I looked this morning, I got this message: 09/11/2021, 21:04 Formal customs clearance required So it appears to be some movement.? What

I get Ts all the time just listening. Noise seems to produce Ts if the code reader is turned on. David J. Wilcox’s iPad

Im still ground testing your Lora pico tracker with no problems. Im going to continue test using a car and solar power only Can i please test your python script to transfer telemetry to the other

Hans, that looks like an Ubuntu desktop, rather than Windows! Possibly 20.04 default desktop background, but it's hard to be sure. As for serial comms, and emulations thereof, it's all Dark Arts, even

Or, perhaps, try 2021-11-10! (Unless you're H. G. Wells' time traveller, in civvies!) 73, Robin, G8DQX

Hi all I'm seeing a growing number of reports from people happily using their QDX and making QSOs. Personally I am quite enjoying JS8Call. This morning I had a nice QSO with YO3FVR on 40m JS8Call

Hi all I think over-voltage BS170s on QDX are a lot less likely than on QCX (where I have never experienced it myself, either) - because Class-E is a lot more sensitive to this and because QDX is

Thanks Ross I have added this to the manual http://qrp-labs.com/qdx I do not see why this should make any difference because it should not be required on a Virtual COM port where start, stop bits etc

Hans, This is done because of the various different frequencies in use worldwide. Adding frequencies is easy. My crude tests seem to give good results. The way? Just enter the frequency you want in
