#SSB on the #QRPLabs #QMX+ 5W HF transceiver is just so unnecessarily painful. The built-in microphone doesn't work. Standard microphones don't work.

The very specific microphone capsule required goes for 21 € inc. shipping from Digikey. A finished microphone assembly by G7UFO is 41,85 € inc. shipping. The whole QMX+ kit is only 125 USD, on comparison.

I have revision 4 of the PCB. Really would have expected it to have been fixed to take any microphone by now, or come with the microphone.

@DC6ST You can get the AOM-5024L-HD-R from Reichelt for 3,15€ I use them in the K6ARK Housing with my #QMX for several Month now.

@DG1JAN 9,10 € (including the cheapest shipping option) makes it a bit better, thanks.

@DC6ST I also wished Hans would just put a fitting capsule in the Kit. Would make things much easier and cheaper.

@DG1JAN The whole absurdity is the QMX+ coming with a capsule. It goes on the front panel by default, but could also be turned into an external microphone.

If it worked.

I really hope PCB revision 5 will just have the missing pre-amp. Should have been there from the beginning, but the whole microphone path seems to never have been tested before the SSB firmware was released.
