Is it possible to use QLG1 (or QLG2 if that is better) with Pi time server? I got the impression is that there are GPIO connectors for serial output. Does QLG1 do PPS signal? Is there a guide? I found

In receive mode with dummy load on the antenna: 100 mA on 20 meters, and 101.3 mA on 10 meters.

Correction, it consumes as much power as it can until the voltage drops to about 6v. I had my power supply set to limit it to 2A. This is presenting differently than the initial issue I reported,

Hey all, I'm still having this issue. I took it all apart, removed the transistors, rewound the bifiller and trifiller torroids, reinstalled everything, adjusted the bias, got everything set and

Thanks, Alison! That sounds good and "under"-charging with buck converters is now my plan, because I did not find an adequately adjustable commercial charger that will do it for a reasonable price. I

Hello Rasmus Apologies for the delayed reply. I'm still catching up. The Rev 3 PCB for the 50W PA kit is quite different to the Rev 2 PCB, in so far as many of the "normal" size and wattage resistors,

Hello Brian, it looks like you have, at least, one bad solder. Starting the resistance between the wire and the pad was high. By pressing on the solder with your probe sometimes the contact became

Hey Roy, I did build a 12V QMX, and I will check that tonight - thanks. 73 Brian K0IK

Caleb, This looks great!? I can't wait to print them. Mike, KL7MJ

Hans, Could you make the QMX terminal RF sweep feature fixed scale, ideally selectable? When adjusting the coils and then sweeping again it's most confusing that it auto-scales.? I have been

I use a small 3s LiPo drone battery. Specifically I use the Turnigy 9xR battery which is 2.2 AH, and has a built in BMS that has overcharge, over discharge, and over-current protection.? Most drone

Hi Brian. Just as a precaution, be sure your QMX's total current draw in receive mode is around or just below 100mA with a 12v supply. (it may be a bit higher if running a lower voltage). Of course my

In my opinion this is not an engineering question, but a product / marketing question.? It was a decision to offer 2 options. I "believe" a big part of that decision is that many commercial rigs are

Hi Dick It's possible, I can arrange it. I'll contact you off-list to set it up. 73 Hans G0UPL http://qrp-labs.com https://www.buymeacoffee.com/g0upl [email protected]> wrote:

Is it possible to place an order and in the shipping part of the order just insert 'Dayton' for shipping info.. then pick up at FDIM or the main Hamvention venue ? Thanks and 73 Dick W4PID

Hello Hajo Then I hereby add it to my ToDo list, to implement some kind of visible sign for WSPR beacon mode, that transmission has been de-activated! 73 Hans G0UPL http://qrp-labs.com

Hello Hans, - Never read the full chapter, for I thought it only is a protection against higher voltage. - QMX Measurement equals not my measurement and when you are in WSPR-mode there are no signs

I think having a couple pins and female headers spare is always a good idea if you work with this type of kits/projects. They can be ordered on aliexpres, for only a couple bucks you get hundreds of

Well, after reading this message I went over to the bench where the transceiver was sitting after I made my last measurements of the FWD and REV voltages, plugged in the power, turned it on, and

Hello Hajo Refer to page 44 of the operating manual. There is a setting in the "Protection" menu called "Supply voltage". There are "Min voltage" and "Max voltage" settings, which default to 7 and
