SSB radio reception
i have a sea 235r mounted next to my 2000r
and the ssb used to drive the 2000r nuts.
i mounted ferrites in the 2 cables on the 2000r and that solved my problem. they are available from radio shack.
you also might try adding a few ferrites on either wire coming out of the heart voltage regulator
i am sure that this can''t hurt.
where are you located?
