Hi Rick, Those settings seem right to me. If you display the heartbeat signal on the LCD and you see it pulsing, I think you can be sure you are disciplining the frequency. This is the #HB special

The QLG2 arrived today and it is now installed in the QRP-Labs SigGen. However, I am confused? 1) The GPS red, yellow and green (1pps) LEDs are functioning as they should. 2) GPS Mode is set to *2

Peter, Been there-done that! - You popped one (or maybe two) of the BS170's - easy just to change all 4. Some folks have even installed sockets for the BS170's - Like "Smarties" always keep a supply

Ron, Thanks for your guidance. I'm glad you are here. 1.) Connections look good on T1. 2.) 10K resistors at R1 and R2? are marked accordingly. ( the radio has been working close to a year now so no

OK. Figured it out. Going through the menus I noticed that the Ref Freq was reset to 27 MHz with the new update chip. I installed a TCXO some time ago, so upon changing the freq to 25 MHz, SWRs went

Well, I guess I spoke too soon! ?VE3EGA, so much for maintaining status quo... (and you should buy a lottery ticket - you called it...) Since repairing my QDX 24 hours ago (and making 20 FT-8

I am using a Orange PI 800 which is a Chinese clone of the Raspberry PI 400 with the QDX.? The Raspberry PI 400 was not available to me.?? I followed the instructions in QDX manual and the work

I think I'm missing something. This behavior is so bizarre: Purchased 1.09a chip from Hans and inserted into 40m mini. 5 watts out with 1.0:1 SWR into a dummy load. All good! Then tested on my dipole

Hi Guys A reminder... Some of you are making it more complicated than it needs to be. Some others are going where no man has gone before. Which is fine too. But it's worth remembering that how to use

John, It's only in the alpha builds. www.w1hkj.conm/alpha/flrig <http://www.w1hkj.conm/alpha/flrig>. You'll have to compile it yourself. To do that for any of the flxxx apps go here and follow the

Hi Joe How many balloons do you intend to launch at the same time with the same call sign.? Technically it is possible with the QRP-LABS tracking website, as long as the channel number is different,

Don't know why you would need a samba server.... What OS are you on?? What is pphAdmin? Mike W9MDB

I think I found the way out. I went back to FLrig and selected QCH+. It activated. I then went to JS8Call and there is a QCX/QDX radio type. AND CAT IS GREEN! Now I need to read the book. All is well.

I have fallen down the rabbit hole. I installed HAMlib and I do indeed see a QCX/QDX radio type, but to install that radio selection I need to use pphAdmin. To install this utility I need to install a

Timo, It all depends on how the tri-filar is connected. It's just three parallel windings on a toroid. You could connect all three is series, tap one of the common points and get 9:1 or, you could tie

Thank you, Muhsin. I had wondered what I was missing. This gives me something to look at and consider. Always interested in learning, though I'd be apprehensive about not having the LPF's. I may be

Is there somewhere I can find the mods, and fixes for rev 3 in one place? or at least a list of them that I can research.. I'll also need same for some rev 1's thanks 73 Vince N2AIE

Thx Ron, Makes sense and is what I expected.? So if bifilar provides a 1:4 impedance step, what would trifilar in the same configuration provide as a impedance step? 73 Timo zr6tm

Hi Stu QDX has 4 BPFs in the front end (selection of the toroid here might be tricky, 37-2 or 37-6) 3 LPFs after the PA output please study the manual for normal and hi-band you'll figure out I did

Hi Tim. In this case it is providing a 1:4 impedance step up from the 12.5 ohm FET Drain to 50 ohms at the input of the low pass filter. Ron
