Odd tuner behaviour in two Yamaha receivers.

Radio Road

Which tuner to get and getting the most from it. Thank God, for the radio!

I have two Yamaha receivers from the 1980s, an R-50 and an R-70. I just picked up the R-70 to replace the R-50 that has been in my workshop for a few years, and is showing its age. The R-70 volume/balance control needed a bit of TLC but nothing serious, and the receiver is working great now; with one exception.
The FM tuner regularly reverts to an even number frequency (e.g. 100.5 displays 100.4), even though it seems to be tuned correctly. You can see in the photo that it doesn't happen all the time. Oddly enough, BOTH Yamaha receivers have the exact same quirk. I only have one other digital tuner, an Accuphase T-107B, but it has never had this problem.
Any ideas?

I am not allowed to have a signature line.
