I can only go by my own personal experience. I have tested used 5 different
DX-398s in the past few years. Each of the units have had significantly lower SW
sensitivity off the whip as compared to the 7600g (I have 2) and 400PE. There
have been mods developed to improve the sensitivity on the 398/909 - which lead
me to believe that is a general problem with that radio. The reports on the
newsgroup of equivalent sensitivity off the whip make me wonder about significant
unit to unit variability on the DX-398. I really like my 398, but it takes an
external antenna and AC adapter to get it into the same league as the 7600g. One
thing to consider when buying the radio as the Sangean version (909) or RS
(398)....Radio Shack's warranties tend to be on the skimpy side. The 398's for
example is only 90 days. Sangean's warranty is a full year.
Which of the three radios is "best" depends on your listening priorities. My
priorities are SSB amateur listening and MW/AM. For me the 7600g is "best" for
that. 398/909 does MW well, SSB well ,but poorer SW sensitivity - so that gets
2nd place. The 400PE does MW well, has good SW sensitivity but is abysmal on SSB
reception - that one goes to 3rd place for me. If tons of memories are a
priority for the SWL, then the 398 may win out. For FM reception, I think the
7600g is behind the other two. If battery life is important - the 398/909 is
easily the worst of the bunch.
Neither of the 3 are "perfect" but each do some things better than the others.
Wonder if the 7600g prices will drop for closeout as the 7600GR is introduced?
