[ICOM] Icom 746 in contest conditions

[Mike]

Hello John,

I've been using a pair of 746s for RTTY contesting and have done 
quite well.  Both have the Icom digital filter, FL-232, in the 9 MHz 
IF and the INRAD 400 Hz filter in the 455 KHz IF.   The 746s are used 
to drive GS-35B amps in a SO2R arrangement when contesting.  A radio 
is used on all the modes without the amp when not contesting.   MFJ 
4125 switching power supplies are used without any noticeable "birdies".

An improvement I hope to try soon is to install an INRAD 69.0115 MHz, 
Icom 765/775 Roofing Filter, in one of the 746s.  If it can be done 
without degrading but, hopefully, improving the contest capability of 
the radio, then will install another filter in the other 746.   Not 
sure if anyone has done the installation of the roofing filter in a 746.

Sorry, but I'm not familiar with the other radios.
