Hi Stan. You are absolutely correct. Setting mode to NONE in both programs seems to have cured the problem. Many thanks. Roger 8P6RX

I think someone already pointed out that the internal mic is also activated during PTT as well as the external mic. Actually, if you enable VOX you can talk through the internal mic and the QMX

Additionally, there is a second REV 1 board with the same problem. I have two case numbers with Hans dealing with this. -- 73 Karl KI4ZUQ

I have some pin-sharp probe adapters for DMM normal probes that poke through that durable film that seems to cover all the SMD joints. The connection, for example between C422 and pin 1 of IC405 can

Hans, A minor discontinuity:? CW memory activates with a double press of the Tune button while in SSB mode.? It does not appear to transmit.? I occasionally get agressive with my button presses on

Alan, I just finished the Mid QMX as stated before. I was supplied the thin .330 wire and completed all the windings. All went well and the kit fired up on the first shot and firmware was applied.

USPS Shipping fee is US$50.55 to Austria.? I'm not sure if there is any customs fee; I think not, but maybe some. But that is high enough that it negates the savings of a group-buy, so it would

Ah, I see, I thought you wrote about tapping on the little hole of the _internal_ mic. As a hardware guy, I am faster with soldering than with thinking :-) Gottfried

I got my replacement chips from Digikey.? The chips are inexpensive, and Digikey has a $7 shipping fee which arrives to me in less than a week.? You can order tons of parts and supplies for that

Yes, this is caused by new CAT functionality. Now QMX+ has USB and LSB selections in the CAT; before, if you would try these commands nothing would happen. So what is happening is that JS8call is

Ludwig, Thanks so much for the insight!? I did just now take a closer look at Q508. The voltages are as you describe, with Gate at 3.3V and drain at low / zero voltage during RX, and Gat at zero,

Thanks for the feedback, Stan! I have a Rev 4 board, built from a kit, and i've confirmed that D516 is in place and seems to be behaving like a diode :) I did also confirm that Q508 shows very high

Excellent!? As I had hoped and expected. The PTT issue is a bug.? Hans fixed it in another update he posted this morning, so if you install the update you should be able to turn off VOX and just use

I made a successful MSK144 contact on 6m with the QMX+ as the exciter to a 300W Solid State amplifier this morning. SSB mode worked great for that. Thank You Hans! I did have to turn on VOX on the

Karl, how are you testing for a continuity break between those capacitors and the IC inputs?? It would require a board fabrication error, or faulty soldering on the capacitors or ICs to cause such a

Gottfried, thank you for your post. I understand the problem caused by the STM32. And like Hans wrote before the analogue channel for the internal mic is used for the reference signal. At first,

Please see my post in the other thread.

Hi Petrov I used a terminal program. Paul.

Greg, I had a QMX for repair on my workbench some days ago. I saw a similar behaviour. Both IC402 and IC403 were damaged. I desoldered T401 from IC402 and saw values at T401 different to the status
