[1000mp] MP/MV second RX Filter experiences

Wed, 10 Apr 2002 18:38:05 -0000

The 500 Hz 455 KHz Yaesu filter is a Collins mechanical filter. It is
sufficiently broad to be useful in the sub-RX, especially if the primary use
of the sub-RX is to monitor a split CW or RTTY pileup to find the successful
caller and to place your own signal.

Some ops may prefer a sharper filter for that purpose. IMHO, the above
filter is broad enough but not too broad.
