OK, if you don't like the mobile noise environment model, let's just look at
raw sensitivity and ignore degradation due to ambient noise issues. Would
you not agree that a good UHF repeater receiver with a GaAsFET ahead of it
will have better sensitivity than a typical mobile radio? If so, by what
amount?
There are some mobile radios out there that are quite hot. But my
experiences have been that the hotter the mobile radio, the more prone to
intermod and overload it is. The high sensitivity comes at a price - lack
of front end filtering. Where I live, "intermod alley" seems to be more
like "intermod county" thanks to Kenwood's wonderful receiver design, which
is why I use it only as a dial-around radio when I'm travelling but
otherwise I rely on an oldie-but-goodie commercial radio for working the
local repeaters.
