Following Hans description of the startup process /g/QRPLabs/message/103064 only with both SMPS are working correct you may establish a terminal session (see number 4 and later number

Section 5.15v in the User Manual suggestws that the SWR can be turned on/off. Have a read and a play around I'd say. -- Compton VK2HRX Sydney, Australia

Hello James, congratulation! Wish you many QSO. Last week I activated a summit using my low band QMX and a broken (!) antenna. 15 QSO in around 30 minutes, 14 EU and 1 NA!!! 73, Ludwig

If it's not broken.... I went to upgrade firmware from 012 to the latest (017).? All went well on the update, except I have lost the SWR display at the top right of the display.? The only indicator

So, I was trying out RTTY via fldigi on my QMX today. I tested receive yesterday, and it was fine. Today, when I try to transmit, I see some odd behavior, in that the QMX leaves transmit mode well

When my QMX took a turn for the worse (magic smoke), I followed the suggestion many have made here. I sent it to Jeff W1NC. What a pleasant experience! In a short period of time I had my QMX back in

Hello I need some help to check my QMX. (80-20 meter version) It is a little deaf and output on 30 meter abt. 1,5 watt and on 20 meter about 0,5 watt. 80/60 and 40 meter abt. 4,5 watt. IC-402 is

Thanks for those Mike. WRT Audio output setting in the setup menu, what about (1) Bit depth and (2) Sample rate? Jim VE4BWG

Correction, that should have read QDX-M. Allison got back to me and suggested using a multi-band QDX, mono band if I like. One just arrived a couple of weeks ago and has not been built yet, I have

Another thought on the input power situation is to use something like a 2 to 4 amp rectifier bridge or 4 separate diodes in a bridge. This can provide 2 benefits: 1. Polarization protection.? Since

Hello Alex I would say both. I would say yes. The SMPS for 3.3 V is working. The processor is working (without processor also no terminal session). But 5 V for much of the other hardware is not ok

I do not see it offered yet, the QMX-M for 60M. If I ordered the current kit 10-11-12, with a little help could it be put on 60M? Ron VE8RT -- Ron VE8RT <ve8rt@...>

Hello all, I’ve just finished building a low band QMX. I plugged in to a 7v supply, plugged the USB into my Windows 10 laptop, and (as is supposed to happen) nothing happened. I pressed the left
