I seem to have dodged this bullet, or something very similar. While powering up my QMX+ for the first time noticed that although it powered up the supply was current limiting.? Tried increasing the

Yes, the SSB software works on all QMX devices, but not QCX or QDX. And you got a good microphone.? I just assembled my kit from Erik and the mic element he is providing is much better (higher

It's really nice to discover what really happened.? Great job in patience and persistence to figure it out, and not just blame the kit - it's almost always something we do that causes the

Hi Zhenxing Thanks, I will do that! But if it works, God knows how many other tracks or vias are open or broken. will be able to do it only tomorrow but will keep You posted. BR Azgael

Hi Azgael, it seems that you're saying the drain of Q102 is not connected to the input of IC101? If that's the case it might indicate a manufacturing error in the PCB. On rev3, Q102 and IC101 are on

Ordered! And I have a backup plan.

I know it's been a Han's project for many years, with many "interruptions", such as SSB on the QMX+!!! Anyway, I recall that at one time, Han's had the vision/plans for a QMX++ (I forget it's real

Hi Ludwig I have been following that sequence despite talking about Qmx and not Qmx+ with embedded sources for 3 and 5v. The voltage out on the mosfet I meant is the drain voltage on both of them.

Correction, it draws 40ma before power switch is depressed.

I just applied power, 7v, limited to 250ma. I long pressed the left rotor encoder. When power jack is first inserted there is no current. After power is turned on, current is 40ma. The QMX does not

Hi Stan and Ludwig, thanks for the help! I think now I know what happened. I believe this was indeed what happened: 1. I did attempt SSB calibration from the on-device menu a few times although I

Hi Stan, I now have one of Eric's little mics to use.? It is nice and small. BTW, do I understand that this new CESSB software can be loaded on my 20m QMX rig, besides on the QMX+? -- 73s, Glen,

You'll probably find this strange but ... I was thinking about portable field use at 12V? power IN with a target of 10 Watts out, for just an extra 6dB (I know, just one S unit maybe, but a bit more

What do you mean by out? Which voltage at "+12V"? Which voltage at LIN_REG_EN when pressing the encoder? Please read QMX QMX_plus Startup ( /g/QRPLabs/wiki/36878 ) to see how start

Hi Doug, May I suggest to remove T1, cut the leads with a flush cutter and then remove the individual pieces left. Use a solder sucker and maybe some solder braid to clean things up. Also if you need

Dear group Took me a long time but finally I have finished a build of a Qmx plus rev 2 (my 3rd kit) and when powering it up nothing happens. so I start debug the power supply with the following

Gwen, Just keep using your wonderful rig and enjoying all those neat keys you have. SSB, especially CESSB is just a passing fad (I heard that somewhere someplace back in the 1960s). Use what works,

Hi Jindra In SSB firmware 003 there's a bar under the 'A' when in transmit with audio. When in transmit without audio it would be a dot under the 'A' (top left character of the display, the VFO
