Ahhh....I have replaced the AAs and I still can't receive any
frequencies. Like I said, I don't have much technical knowledge.
What's this shorting of positive & negative contacts? And might it
help? I've taken out and re-installed the AAs many times now and it
hasn't helped. I can even take out all the batteries (Ds and AAs) and
run it off electricity and it still won't tune in any stations.

Thanks,
Joe

You need the AA batteries for the computer even if you're running off
AC! Try taking out all the batteries and leaving them out overnight.
Then replace them and try again.

"Shorting the contacts" will presumably discharge any capacitors that
are charged, but this charge will "decay" if the power is completely
removed for a long enough period of time (like overnight).

If this doesn't help, someone has fried the sensitive FETs in the
front end (RF stage) of the radio. RS can fix it, but I bet you can
save money at a local shop.
