Over the years, I've had several of the small coils in both the LP/HP and
bandpass filters go bad...I'm sure due to excess RF. They seem pretty
fragile. Since I started using RX limiters in the RX line, I havent had any
more trouble.

Subject: [Yaesu] Ft1kMP loss of receive gain
I am noticing a receive loss of around 10-12 dB. I have checked Antenna
B and receive antenna inputs. They are the same.
What I do notice is around 2-4 s units difference in indicated signal
strength between main and sub Rx, which would indicate the problem is
after the 1st mixer.
We recently used the radio as a spotter in CQWW CW at G5W . Whilst it is
unlikely, we could have zapped the front end somewhere.
Anyone got any thoughts?
