Hi Guys,

?

the SSB modus for the QMX is awesome. Even with a small Magnetic Loop antenna.

?

I?m Using a microphone of the QRP-GUYs from California, USA. At the Antenna connection (bnc) I also use a LED SWR bridge from the QRP Guys. So I can tune my magnetic Loop antenna with full power about 4 Watts with 11V Supply(3 Watts keep in the bridge resistors..lol, 1 Watt will be used for the measurement) . When the LED goes out, I can switch into the operation mode. I NEVER switch of the SWR Protection off (SWR3 in the Menue of the qmx).

?

Has anybody an idea, if the internal microphone can be activated in the nearer future or will there maybe have to do any hardware change ?

?

enclosed my? video? :) :

By the way, I?m using a DC-DC converter to reduce the voltage to 11-11.5V . And yes, it doesn?t make any noise, believe me, Its a quality module from an european electronic supplier and not a cheap piece of sh.. from Temu ! Im using toroids around the voltage supply cables (lpf).

?

Have much fun with the QMX. YOu really did a great job Hans ,

Hallo.?

Reichelt Elektronik. Mittels Poti kann die Ausgangsspannung stufenlos variiert werden. Z. B. 8 V fuer WSPR 12.6 volt fuer den qcx oder <13v fuer den qmx

Das Progranmm von Reichelt ist gigantisch. Hast du noch die genaue Bezeichnung?
