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. ~Brett -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Iain MacDonnell - K6IAM Sent: Monday, July 28, 2008 11:57 AM To: Mark Volstad Cc: [email protected] Subject: Re: [Elecraft] K3: General Coverage Receive Filter Hi Mark, Can you be more specific?
