Dear David,

I too have a Sangean ATS-606AP though it's "retired" now; its
microprocessor was starting to "go" - the internal quality of Sangean
radios is not all it should be, at least in my experience with two
Taiwan-made units (the '606AP and an '818A. Formerly my travel radio,
the Sangean has been replaced by one of my Sony ICF-SW7600G receivers.

However, while my '606 was still functioning properly, I tried using
the Sangean wind-up antenna (via its 3.5mm plug), a Sony AN-LP1, and an
AOR WL-500 Window Loop.

While the wind-up antenna didn't improve things very much, the AN-LP1
and the WL-500 improved reception noticeably; the WL-500 was superior
to the AN-LP1.

I certainly wouldn't suggest that you buy one of the above just on my
say-so, but if you have an acquaintance who has one of them, why not
try it? I think that you will indeed notice a major improvement in your
radio's performance.

My Sony ICF-SW7600G and 'GR models are easily as sensitive (if not more
so)
with the whip as the Sangean ATS-606A and the Sony's synchronous
selectable sideband circuity makes listening much more pleasurable.

Any radio's reception will improve with a suitable auxiliary antenna.

Best,

Joe
