Hello all,

As of this morning, power and ALC fluctuates while transmitting in FT8. The problem appears on every band and no matter the power i use. In WSJT-X the power slider as no effect on the ALC.

here is my setup:

Radio: 7610
Tuner: 7610 built-in tuner
Antenna: MyAntennas OCFD-8010
Power supply: Astron RS35M

This setup has been working for months. My last transmission was yesterday around 22:30 (local time) and it was ok at that time. I tried shutting down WSJT-X and power off/on the radio but the problem remains.

Any ideas what might be causing this ?

Many thanks
