Re: QMX+ SWR sweeps with SSB firmware?
I just ran a SWR sweep on my QMX+ which is running version 3 of the beta SSB SW.? I am not seeing any change. Have you verified that the you didn't lose one or more of the BS170s (final power

Peter: 1) People are already using multi tone digital modes. 2) The QDX does not include amplitude modulation capability so SSB is not possible

Re: QMX won’t power up
Stan, I connected a Fluke 289 in series on the +DC leg of a 12 VDC power adapter measuring 13.4 VDC output at open circuit. QMX was unplugged to ensure it was off.? Plugged in with the barrel

QMX+ SWR sweeps with SSB firmware?
My QMX+ seems to be working fine but I just did an SWR sweep and something looks bogus. The SWR is approximately correct for the chosen band but it is flat across all of the frequencies with only a

Well ... Certainly not hidden.? Both Assembly and Operating manuals for the QMX+, in all its versions, are in the section titled 'Documentation' on the main QMX+ web page.? GREG Yahoo Mail: Search,

Re: RTC battery mistake
This is a jumper on the board, it is only relevant if you have a GPS module.? It's mentioned in the QMX+ assembly manual which is hidden in the QMX+ section of the QRP Labs website.

Re: SWR and PWR does not show lcd

Re: QMX+ Power Output Question
Jim - How do the LPF (Low Pass Filter) sweeps look for the upper bands?? If the low pass filters are kicking in a little too low, you can back out a turn or two on the LPF coils to raise the cutoff

Re: SWR and PWR does not show lcd
I've tested it in DIGI mode. And yes, I'm transmitting on multiple bands and everything is OK. Another colleague is reporting the same issue on QMX+ Rev 3 with the latest firmware. I've tested it with

Re: Gibberish characters appended onto end of Message 1
I got the gibberish as well.? Now I am nervous about broadcasting it. Is there any way to play back the message without transmitting?? When I try it in practice mode, it won't play?

Re: SWR and PWR does not show lcd
I see power and SWR displays with my QMX+ firmware 1_01_003 in CW, digital, USB and LSB modes. I don't recall it not working on 0_27, I would probably have noticed. Have you configured it
