Re: QMX+ Broken Toroid Core
If there are just two large pieces, you can superglue them back together and it should work fine. If there are multiple chunks, things get a little dicey. Jack, W8TEE

Re: QMX SWR measurement is not correct while using with PA
Correction:? You also need to know the phase difference between the voltage and current.? That's why you need two oscilloscope channels. <? then you have all the information you need to compute the

Re: Solder pot for toroid leads
I wantched a youtube on the "$20 Amazon solder pot" and it looks like he had to fill the solder pot with almost a complete 1 lb(?) bar of solder, which seems to be about $30. So, I went looking a bit

Re: QMX+ SSB audio distorted on one band only
I have a 20-10m QMX which I ran beta SSB firmware on. 20m wouldn't calibrate, but I tried Ellis Simon's band edge and band centre values and then the rig calibrated fine. I've just upgraded the

Re: Hi SWR, sometimes
Dean, there is a fault in the SWR tune function (until now). If you start the SWR tune function your last VFO frequency is shown but a per band default frequency is used. Please rotate the frequency

Re: QMX won't start after firmware update to 1_02_000
Power down by removing the power plug. Then see if it will power up normally.

Re: RIT in N1MM
Stan, If I understand you correct, QMX + RIT and N1MM won't be a happy marriage by design. The RIT switch off issue in RUN mode is kind of weird. Anyway, it is a great contest radio. Enjoying it at

I may have the same issue with my QMX+. It enters Safe Mode as soon as the key is pressed on 80m and 60m. The 40m and 30m bands work fine, although 40m and 20m have nearly zero power output, which I
