FTAOD seems to be a legalese thing, had to look it up. Took me some time to find that on the web. A slight misspelling on my part brought up lots of very cute images of amphibians, which distracted me

Hello Sergey, My QMX+ seems to have neither issue you are reporting. I am driving a Juma PA 100D clone successfully with SWR protection enabled. To key the amp I had to go into the menu to enable the

Hi Dean - Glad to hear you were able to get yours on the air! -- 73, Don K0DBL

Thanks Stan - Actually, I ended up buying a new one already assembled.? I donated all of the internals from this one, except for the GPS module, to Jeff for his excellent service to our

To Whom It May Concern, When will SSB be ready? That was another endless topic. It's now put on clothes. Just curious is there room for DIP switches to juggle a microphone connection? (I went

The attenuator is after the TX diode switch.? Not a factor. However the RX switch does not have enough bias current to transmit thought it. Still at, you cannot, even when powered and no

Do you have the mouser part number?

I played around with my band setting for 20 last night, and the plot did not change with much significance.? That said,? I have been able to Tx with good audio after re-running phase, and USB

Meant to include. This method worked equally well for the two wires twisted together, as on the transformer, as it did with a single wire.

I’ve been using my Weller WSD81 station set at 375C and a 1.6mm chisel bit with great success. I've built quite a few QRP Labs kit, with last week a QMX+ and a QMX 20-10. On previous builds I’ve

I've just started building my QMX+ kit and what I found was that I needed an indicated temperature of 440C to burn the enamel off. My normal 380C barely touched it.? I'm using a WEP 926 LED soldering

Plus PTT output doesn't work properly. Nothing changes there when I start TX. BR/Sergey UB3AZK

Hello Hans! Looks like there is a bug with SWR measurement during usage of PA. QMX detects very high SWR during TX threw PA and stops it (if protection is switched on). In reality SWR is 1.1

Menu -> SSB -> Input -> Ext. Mic But it sounds like your mic cable is wired backwards.? Mic signal needs to go to ring, ptt to tip.

Just updated my QMX+ to 01_01_003 Beta. Plugged a modified Baofeng mic into the front panel and tried running the microphone test. It doesn't seem to work. I can tap on the front panel, and that

Thanks Evan and Nate! I found the threads and an answer of Hans in an older conversation: My Bpf simulation is too simplistic. Impedance and the environment have a big influence. 73 Peter DL4PJ

I would guess that 100% of the QRP Labs kits are shipped with some manufacturer's thermaleze equivalent wire. I would further guess that a very, very small contingent in this group would use their

I started from scratch and got it working. As everyone suggested, I needed to do a better job removing the enamel from the P wires. Additional heat did the trick. Thanks everyone!

Hm, thanks Stan. I ran the auto calibration the other night so that's fresh. I can reliably get level 5-10 on receive, but it doesn't seem to get out of level 1 or 2 on transmit. [email protected]>

No, it doesn't necessarily happen every time the radio keys, but it does seem to happen at least once per VARA/Winlink session. [email protected]> wrote:
