Re: New Prebuilt QMX
Well so much for the simple stuff. :) I had a hunch you were doing things correctly. If it were me, I'd take the radio out of the enclosure and CAREFULLY start checking voltages. First thing would be

Re: wsjt-x 2.7.0-rc7 issue with QMX+
Mark, The WSJT-X group[ seems to indicate a Hamlib problem. Look there, I think there is an answer. (No point in running rc versions unless you are prepared for bugs or there is something new you MUST

Re: New Prebuilt QMX
thanks Greg. yes, I am pressing the left knob and holding for a couple of seconds. I have tried longer and shorter presses just in case. The USB c cable and USB A to C adapter are the ones that I use

Re: New Prebuilt QMX
May not apply in you case ....? But .... Are you pressing the encoder knob to turn on the QMX? And for the PC to recognize the Q ... It's important that the QMX is powered off. Then plug in your USB

Re: Pop Go The QMX+ABS Finals! (Now replaced but still no transmit.)
I does look like very nice stuff, Donald. I think I will order some of it. I might have a problem that I've only noticed after my repair, due the the limits I've set on my Drok regulator. On 12m, when

Re: New Prebuilt QMX
OK... I did some more troubleshooting. I tried two different battery packs (both Talentcell 12V), two different power cables and verified that the battery packs work with my QCX Mini and FX-4CR. I

Re: New Prebuilt QMX
I understand! I ordered in early August and waiting for it to ship only to have it arrive dead is disappointing. I have a QCX Mini that I bought used and it is great, so I have high hopes for the QMX.

Re: New Prebuilt QMX
Scary when I often see these failures happening.? I find myself hoping my QMX+ Order ID 91594 - Serial 6457 - Ordered 9-17-24 works as it is now #84 on the list. I know is a kit and made by humans

Re: QMX+ with HardRock 50+ amplifier
You can decrease the output of either a 9V or 12V QMX by decreasing the input voltage. For any given input, a 9V build will produce more output power than a 12V build. I have neither tested it nor

Re: QMX+ with HardRock 50+ amplifier
The QMX/QMX+ work fine down to a supply voltage of about 7.5V.? Somewhere around 7V it will cease to function.

QMX+ with HardRock 50+ amplifier

Re: QMX + manual tuner, SWR protection
I use a Emtec ZM-2 Z match tuner for my QRP rigs.? It has a Tune mode that puts a resistor bridge between the radio and the Z match, it also has a tune LED that will go out when you have a 1:1

Re: ABS for QMX+. Battery/charger design improvements over version 1.1 #PSU #QMXplus #ABS
Sardar, Dirk, I'm planning to order 5 rev. 1.3 Companion boards today so Stan and I can evaluate them. We think it's worthwhile to delay the big group buy so builders will not need to add large wires

I use an LDG RT-100 with my QMX's in QMX Test mode at home QTH and have for 9 months now. The RT-100 does a lot of hunting before settling in. So far so good. If I forget TEST mode, I get a SWR

Re: KANGA kits
I've built and use Kanga Pocket Transmatch with my QMX's. Half the size. I noticed that match on transmatch is different from match on rig. Read somewhere to match the rig. Makes sense.

Re: QMX + manual tuner, SWR protection
Eben, As Stan says, "Hardware tests -> SWR" is the way to go.? I reduced my 'voltage' setting to 40%, and use the hardware tests SWR measurement to set my Z match.? I have no fear of plugging in

Re: Auto-Tuner at 9V for 12V QMX/QMX+
Rich The EMTECH ZM-2 has an absorption bridge that is in during tuning. The radio being tuned never sees a greater than 2:1 SWR. -- 73 KD8CGH
