Well, if I'm searching and pouncing for multipliers in a contest I like to tune down the band and hear what I'm coming up on before I get to it. 1 kHz is about right for that. That way I can tune more quickly than if I have to sit on a frequency long enough to see if someone's there -- someone I want to work may be listening to someone I can't hear and I could skate right by them if I went too fast. A wider filter makes this possible. Of course you can use a 2.7 kHz roofing filter + DSP which is exactly what I plan to do, being too cheap to buy the 1 kHz filter. If I were a more serious contester, I'd get the 1 kHz filter. It could mean an extra multiplier or two now and then. 73, Carl WS7L _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
