Hi Fred, I stayed with the standard 2.7 khz filter for SSB and went with the 1000hz filter for CW.
With my antennas here, the best one being a 2 element yagi for 20m at 30 feet, there is little chance that in a contest there will be a signal so big as to unsettle the hardware AGC in the K3 and then cause trouble with the DSP that would be within 1khz of me. On the rare occasion that it happened, I can just move since I so search and pounce in the contests. If you are a contest guy that has big antennas and wants to run (call CQ) and keep your frequency, then you may want some more CW roofing filters of a lower frequency value but the way I see it that's an extreme scenario. On SSB, the standard 2.7 filter is probably optimal as well for the vast majority of normal activity, given the strength of the dsp. My guess is the 1khz filter in my setup here is actually just insurance, I'd probably need it more if I had a neighbor that's a ham and we operate on the same band. =================================================== [Elecraft] K3 - Which are Std. Narrow CW & SSB Filters? from [Fred (FL)] [Permanent Link][Original] I ordered the basic K3/10, with one (1) KBPF3 GC Rx filter and the MH2 Mike. Which of the other filters - would one consider the "standard" reasonably narrow SSB and CW filters? In other words - not too narrow, but narrow enough to do their job during crowded CW and SSB band conditions? 73 de Fred, N3CSY _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
