Set the menu to mute at minimum volume, then just turn the volume down. -- 73, Dan - W2DLC

How do you fit the 4States Group QRP Tuner inside a QMX+ case? Is it with the QMX+ radio or is it just a different case?

Hello, Can't find this answer anywhere and this is my last try. I would like to properly key my transceivers from the computer with a dedicated keyer. So far my K42 worked very well, but it is a

Hello dear all and devs, Several hams on our side have equipped themselves with the QMX+. Some would like to know if it would be possible to add a few lines of code to the firmware so that when PTT is

I would like to block Digi mode audio from going to the earphone jack. The audio levels are painfully loud when adjusted for correct usb output to WSJT-X. I am afraid to switch between sidebands or to

Hello Hans, Thank you for your help. N1MM features the usual contest modes Run and Search and Pounce (S&P). In S&P mode? and engaging the RIT on the radio, nothing happens using the CAT Monitor in

Thanks again, I resoldered all eight points and now I get proper SWR readings! I didn't find where to measure ADV_REV and ADC_FWD but I now get good readings that match my NanoVNA (at least where the

Eugene, You might want to also consider ordering some TN0110 FETs, a BS170 alternative, to have on hand if you decide you'd like to experiment with a hardier device. I'd also suggest order a few 5ft.

Lower your SWR protection to "2". If it's a 12-Volt build, run it on 9-Volts for digimodes. Doing those adds a larger margin of error.

Hi Stan ….you said… a) Transmit EQ - note that sometimes the 'global gain' here defaults to 20 or some high value, which distorts the tx audio; change it back to 0 (this could be the reason for

Hi Michael, not sure what ‘sidebands’ you are asking about. The ‘spurs’ I see strongly in receive on 6m, 10m and weaker progressively as I go LF in frequency, are every 500Hz, strongest at

Printing is sometimes useful for highlighting sections. ? Also for Writing notes, menu settings and measured voltages on a schematic for future reference On the other hand using a display lets you

Hello Ken Have same issue. Could detect LO signal (RX -12kHz,-40dBm) and additional sidebands at 6 m and 10 m at BNC (RX).see also my Posts. Another OM also detected these Signals. Resoldering

Stan, many thanks for that, I will try your suggestions. Before you replied I tried an interesting experiment, in case the problem was with my microphone... I set up my QMX+ for WSPR transmissions the

Yes, all terminals of T507 are at DC ground.? The inductors allow the RF signal to pass, and generate the FWD and RVS signal detection for power and SWR calculations.

I redid my windings as you suggested and they came out better.? Not perfect but better. After soldering in place, when I checked the connections with a DC meter on ohms everything seemed to be very

Good idea to have spare 74ACT08's if you plan to blow the BS170's. When the BS170's fuse up internally I'd guess the 74ACT08 gate drivers might see 12v, at least for a moment. Look on Mouser or

New to the group - wanted to say Hi and since this thread is about observations and best QSO - I wanted to share my recent experience with the QMX+.? I am very fortunate to have an awesome? brother

Hi Mark, How did things go with your setup? I’m in exactly the same situation! I’ve run all the tests, and from what I understand, the MAX3221IPWR chip used in the IC-9700 should be able to

I threw a few condenser mic elements into my last order, the one Hans recommends for the QMX. My whole order had a 10% tariff fee added on, which didn't thrill me.
