If the radio is sensitive and overload resistant, then it may be worth
looking further.  If it has a standard IF frequency for which better filters
are available, then swapping the wide stockers for some better ones may make
a star out of it.

The original Delco radio in my 1988 Blazer was quite sensitive and
definitely intermod resistant.  On FM I changed the factory wide filters for
a set of 150KHz Muratas and it made a *huge* difference.  I have literally
hundreds of Murata 110KHz filters left if anyone is interested.

Unfortunately I could not find any filters for the AM side of it.  And, it
only tuned up to 1620.

FWIW as part of the ultralight discussion..

The Sony ICF-SW100S is another pocket-sized rig.  Has a sync detector,
150KHz-30MHz coverage, LSB/USB as well.  But it's not all that sensitive.
It really needs help to hear distant and weak stations.  Put inside a
passive tuned loop or next to a tower guy wire and it comes to life.  By
itself it's fairly deaf.  It's also too expensive to fit the Ultralight
definition.
