Pretty neat idea, Yoon! You're giving the KH1 a run for the money! -- 73, Dan? NM3A There are moments when everything turns out right .... Don't let them alarm you; they pass. -Jules Renard

It sounds as if the left encoder is not working properly. Check on the terminal diagnostics screen. there are a number of RED items. when you successfully exercise each of these items, the RED will go

Et

I think that will work ,Todd. You will be adding a tiny inductance in the source of Q507 because of the length of the new lead. You might plan for an additional 100nF capacitor from source to

Hey all, I just found out that the RING connection on the output jack is connected to PIN 5 of the processor in the Ultra PicoKeyer. I am not sure why this is connected, and it is not shown as a

Hmmm.. that's a brilliant observation. Just wrap a small line around the edge of the board (convenient with the MOSFET in the corner). Logically enough, R507 and C507 are next to each other on the

Todd I'm pretty sure you can recover gracefully. Check to make sure that the resistor and capacitor remain connected to 12V. There may be a way to pick up +12V for the source lead right at one

I don't think it is just me that uses QMX as an HT, so there can be different versions of QHX. This is about my version of QHX, integrated with the 2s 14500 batteies and the micro-size single lever

You might also use the terminal mode to run the diagnostic to be sure that the encoder and all are working... That's all described in the assembly manual. Also, when you power on, is it showing you

Hmmm... Good news and bad news. 1. I took voltage readings from Q507 (AOD403) with my 12v QMX powered on as follows: Source: 11.98v Gate: 11.88v Drain: 6.6v With the device powered off, I measured a

Juan, Maybe the issue is the earphone jack?? Can you try connecting a speaker to the board connections of the jack?? The other possibility is the audio amplifier has failed.? Do you have a way to

Thanks for your responses Ron and Evan. I did what Ron told me to do and I also did the factory reset but the volume control still doesn't work, that is, I can't raise or lower the volume from the

Juan, Did you do the factory reset? 73 Evan AC9TU

Juan, one possible solution for your volume control issue: please do a long press of the left small button to get to the menu. "Audio" will appear. Do a short press of the same button and "Volume

I was able to update the firmware to the latest version, but the volume control still does not work 73, Juan LU9CYV

Yes, The QMX can not get power from the USB cable.? It needs a separate power supply.? This is best done for the first time with a current and voltage controlled supply, starting at 6.5 to 7 volts,

Juan, That's not a stupid question at all. QMX receives no power from the USB port, so unlike a thumb drive for example, it definitely requires a power supply to connect to the computer. JZ KJ4A

A stupid question.... Does the QMX have to be connected to power for the computer to recognize it? 73, Juan LU9CYV

Thank you very much Evan for you response. 73, Juan LU9CYV
