Hans, Page 107 of the manual requires changing, two references to 160m. 73 Alan G4ZFQ

I will be doing another CW on the air practice session on Friday 10 January on 30 meters. Anyone is welcome. This practice is intended for operators who are new to CW or they need some practice. IT

Hugh, the QMX plus does work on 160M. ?I think you have a poor solder joint on the band pass filter L401. ?It is tapped, for 160M and 80/60M. ?Your output is good on 160, so the LPF is fine. The

I activate almost every park I do with a QMX I buillt (mid-range) and it's been flawless. I'm on the latest firmware and it's been wonderful. However, last weekend I activated, I was working on 20

Same problem on my side. After a couple of QSO's, QMX does not start up anymore.. Gérard

Thanks for the response Alan, I was under the impression that was the QMX not QMX +, but if that's so I can rest easy? and wait for a firmware upgrade. 73 Hugh

Despite have a good stock of BS170 MOSFETs, I don't apply power to my QMX unless I have something connected to the BNC connector. I'm just too forgetful. Apologies for the unsolicited advice. 72 de

Many thanks Nick. And first result with 8V ps , builded it for 9V. 73 hanz YL3JD

Glad you got there in the end Hanz.

Yes a termination on the output will help, but possibly more useful it’s to set the sidetone to ‘absolute’ and turn down the volume. ?This enables you to adjust the sidetone level independently

Many thanks Greg. Yes the USB interconnections can make us mad HI. Now next step, looking forward to to work with it. Take care and 73 hanz YL3JD

I started with these parts: -- 73 Karl KI4ZUQ

It's a 12V version by the way. Also dropping price to $200.

The current manual says " because 1.84 MHz is in the 160m band and this is not one of the bands currently supported by QMX." I think this is still waiting a firmware upgrade? 73 Alan G4ZFQ

Hi, Has anyone do an offline test for the SMPS ? I mean do the process explained on? /g/QRPLabs/wiki/37128 Testing on PCB#2, step 1 is OK, but when I go to step 2 and ground

Is it possible to disable the RF input when using practice mode?? There is significant background noise when practicing morse, since I can't turn off the reception..... I guess a dummy load will

Now that's persistence. Congratulations.? That pesky 'off' before plugging in the USB cable drove me crazy when I first started trying to connect my IC-7300 to WSJT-X on Windows a few years

I have recently finished the build of a QMX+ with RWST transformer for 12V operation. I have gone very cautiously with testing via PUTTY, starting at 9V and always with a 50 ohm dummy load. I’m
