[R-390] bad audio

[James Bischof]

I was just a thinking about the audio that comes out of a r390a. I must have
had about 10, r390es in my hay day. I have never heard good audio coming out
of these receivers, never. I think it is impossible if you ask me unless one
takes some drastic measures. Many years ago I made a solid state if
amplifier for my r390a. When I did that I got good audio. Of course I did
away with the Collins mechanical filters. AS far as I am concerned they are
junk. Talking about the old mechanical filters. Maybe the new ones are ok ,
but I have not played with a newer radio that has them. I Just felt like
expressing my self to night on the subject. James
