Not an AM radio? (IE - needs antenna tuning - or is that long gone?)

No I don't think its an AM radio. I plugged my old HU in and it seemed to have the same reception problem, so my only guess is that the antenna wire has a problem somewhere.

Peter, I have not seen an antenna trimmer on any modern digital tuned radio.  That went away with analog tuners.

Thanks Idiot. It probably goes with impedance matching... (you know, that some idiot used to think cause amp overheating with HIGHER impedance speakers). I can't recall if my AM/FMs have or had it, but it was something I read recently - though I presumed "AM" referred to radio age - and I have recently been playing with some car-collectors' AM radios. And now I am curious - digital tuning is one thing, but impedance tuning? Another trivia for the new (next!) millennium....
