[Elecraft] K3: General Coverage Receive Filter

[Brett Howard]

The K3 has greatly reduced sensitivity outside of the Amateur bands.  The
bandpass filters are designed to be just slightly wider than the amateur
bands so as to reduce interference caused by broadcast stations outside of
them.  

Well if it's the broadcast stations that you want to listen to these amateur
only band pass filters give you poor reception of the broadcast bands.  The
general coverage receive option gives you a path around the amateur only
band pass filters and provides wider filters for when you want to listen
outside the ham bands.  Granted the K3 has the ability to receive between
the bands with out the module but the receiver is not being used to its full
abilities unless you install the general coverage receive option.

Hi Mark,

Can you be more specific? What function of the Drake or JRC could you
not replace without the general coverage receiver option ?
