[RTTY] Filters

[llindblom at juno.com]

In my Icom 775 I have an INRAD 250 Hz in the 455 KHZ IF and an Icom  330 Hz in the 9MHz IF.  I also have 500 HZ Icom filters for both IFs along with the narrow Icom SSB filters.  

Each seems to have it's own advantage and disadvantage.  If several stations are calling at the same time the narrowest possible filter combination often allows one station to print clean while the others who are a might off frequency do not print.  Also if someone slides in too close to a good run frequency the narrowest filters come in handy.  But when stations are calling in one at a time the wider filters make it easier to print someone who is farther off frequency. 

Maybe filters are like antennas in that one can never have too many of them available to use;-)

250 is just right for serious RTTYing.  400 isn't bad, but it's wider
than needed for RTTY.  400 would be good for MFSK16, though.
