Hi Mehmet, I am sure that it helps but I am trying to minimise the number of potential points of failure as I sometimes operate portable. Aborting an outing because I forgot to check the microphone

Many Thanks Stan 73 Bernd Dl3BLA

Hi Yanning, If it helps, I use a MAX9814 Arduino mic amplifier module powered by two AA batteries. The module come with a mic capsule on board. I removed the mic capsule and wired it to my gaming

Hi guys, Is there a way to see what bands/frequencies i have stored in the U3S ? It may be that I am not saving my setup correctly, it appears I am only storing 1 band at a time, not all 6 ? Thanks.

I would first make sure all is functioning correctly,? RX and TX, before trying the calibration.? ?That removes one variable if something needs attention.? ?The calibration is optional,? and

Excellent!? I'm glad you found & fixed it. Mon, May 19, 2025 at 12:37 PM, Lincoln Thormahlen wrote: When you made this change, if you just did it via the menu, not everything will work correctly.?

Thanks Ludwig, I didn't realise that the 3.3V was just for high impedance. You saved me 5€ ! 73, Yannig F4IUJ

Yes, all versions of QMX and QMX+

Hello Does the SSB firmware work on all versions of the QMX+? I have a board with revision 1.0 Many Thanks Bernd

I use this one: https://www.tme.eu/en/details/ld-mc-9765/microphones-and-headsets/loudity/ It is -30dB. Works perfectly, I need to reduce Mic gain to 40. As far as I remember cheapest shipping they

Richard, Tried factory reset - no change. Same RF Output....

Yeah, the SMD caps are just on bottom of the board, just like Dan's photos. Cheers, Glenn VK3YY.

Hi Russ, I was a bit lazy and didn't reorder 40m to be the first band in the sequence.? The sequence is currently 20, 17, 15, 12, 40, 10. Cheers, Glenn VK3YY

Nico, Check IC503 (four 2 input AND gates). Two of the 4 outputs were shorted on mine. My QMX+ was working flawlessly for a long time.? When I added the SSB FW I was playing with the VOX and it might

Yes, I am getting a genuine 4W+ output on 60m using my calibrated LJ-2K+ Power Meter. Hmmmmm, will give that a try - never thought of doing that. I will advise later. 73, Robert VE7ZN

Are these the correct spec BS170? MOSFET N-CH 60V 500MA TO92-3 https://www.digikey.com/en/products/detail/onsemi/BS170/244280 I just heard a pop doing a POTA at what I thought was about a 2 SWR but

I figured it out. For some of the SSB config fields you need to type in a value while others need a left/right arrow to change the value. On the compressor field you must use the left/right arrow. If

Hi Peter! It's a piece of velcro! It's how I attach 2S battery packs to my radio for field use. I use 2S 18650 holders for FPV goggles, they happen to have the same plug, and come with built in

*What it does:* use the LCD to display characters received on the CAT serial port and characters transmitted over the serial port. The RX data could appear on the top line and the TX data on the

Michigan QRP Club On May 19 I had another one of my CW practice sessions. I worked three stations. Conditions were OK. SSN=53, SFI=117, A=10, K=2.I used my Elecraft K3 at 100 watts and a 100 foot
