It is quite possible that there are some components in the tuner section that have 'gone south' - could be a diode - but more likely a cap or resistor - possibly even an op-amp or transistor-
Getting a 'tuner alignment' may solve the issue - if you can find a tech that can do it-
if the problem affects both the FM and AM, then the issue could well be in the AM section for the cub-carrier signal or the MPX section-
Happy Listening

Some one on the Vintage Asylum mentioned about a Roku being close by can cause the problem so I am going to check that first! I do not think that alone is causing all the problems,so if there is not much improvement,I will need a good place in WI. to take it in & have it realigned!Thanks for your advice & help though!
In the 'Audio' article there's a design for a spread rhombic with a wider pattern.
If it were me with all those stations mostly in one general direction I'd build that.
