Whew! pretty awesome!
Guess what farmer Christmas will put in some lucky fella's stockings

But why, oh why, do Icom have to attenuate the MW band reception? - never
figured them out - they do that to all their radio's.




They do this to prevent front end overload for users in high MW
signal areas. There are some areas of the Windy, for instance, that are
a veritible RF 'Little Big Horn' of huge signals (50 kw).
It's not a problem for many users, but when it's a problem, it's
usually a big problem.

Padding the MW band is a lot easier and a lot less expensive than
increasing the headroom to accomodate signals 100 times or more hotter
than the average DX signal.




Do you suppose there will be a mod possible to defeat this unfortunate
design "benefit?"

There usually is. Most of the time as simple as jumping a pad.

Except in the case of the R-75. A bit more complicated...
