Sudden, strange Accuphase FM tuner behavior


I listen to a lot of FM radio through my Accuphase T-100 tuner which has been flawless since I bought it about six years ago. The signal level, as indicated by the signal meter on the front of the tuner, is usually just above 4 while listening to a local station (the meter goes from 0-5). While listening the other day, the music stopped and the signal level went to 1.5. I discovered that if I put the FM muting selector to “1” or “off” instead of “2” (where it usually is) the music comes back but with a little more static than prior to this problem. The signal level is still at 1.5 with the FM muting selector at "1" or "off". What is going on here? The service manual is available here, but I couldn’t find anything that points to the cause:

Something could have changed between the stations
transmitter and your location. It could be anything like a new
building or the landscape ( trees,etc)is blocking the strong
signal you had. Reorient your antenna and see if that helps. If
the other stations are clear the tuner is working fine.BTW,I
had that tuner many moons ago and it was the best sounding
tuner that I have owned !
