I have a "Grundig TR II". I purchased it about 7 years ago for use
mainly on camping trips. I find that with the internal antenna it has
limited reception, at least that is the way it seems to me. I do not
think the radio is faulty. I suspect that if I put an external antenna
on the radio it would pick up more stations. My question, has there
been improvements in the reception sensitivity of small portable SW
radios that would justify the purchase of a newer unit?

Thanks for the help.
