Lacking what, specifically? I wanted a general purpose radio with full AM
coverage to 30 MHz, and I wanted it to be cheap and portable. Then I wanted
to give it a decent chance of getting signals when I'm not carrying it
around.

As for a radio that that is only fit for getting BBC World Service, are you
sure you're not confusing the ATS-909 with whatever Sangean's original was,
as cloned by Roberts with model R9921? That really IS a basic radio designed
for that purpose, the ATS-909 does more.


Yes, but you were not talking about the other bands that it covers, you
only mentioned HF.


Even you admitted in an earlier post that it was overloaded by anything
more than a whip antenna!!


Not the point. It's easier to attenuate than to do almost anything else. Even
the radio itself can do that.


So why are you so worried about the co-ax and SNR, if you add an
attenuator in order to make the radio work properly you will also
attenuate any interference (and degrade your SNR).


You would be far better off buying a dedicated HF receiver or a
transceiver with a far superior performance. They are available on Ebay
as well.


If you know of any that fit my description above, please name them.


Virtually any comms receiver will give you coverage of AM to 30MHz, many
also have Band 2 vhf as well, they are too numerous to mention, but have
a look at this link and pick the ones that actuall have good RF performance:
