Hi Gary,

This might need more runtime from other people to be sure of what's going
on, especially since some others (i.e. Rick) don't seem to have that
problem.

I will note though that there were some tweaks to the transmit level for
the RADE signal, so as a reminder, it's always good to make sure you're not
causing ALC to trigger (adjusting the TX Attenuation slider as needed).

Thanks,

-Mooneer K6AQ
