I think Doug has hit the nail on the head. For casual CW, just use the DSP. If it isn't good enough, you can always add the 500 Hz roofing filter later.
For more serious CW operating, I'm thinking the next filter to get is the 1 KHz filter to give better tuning-across-the-band performance. My 3rd choice would then be the ultra narrow (250?) filter. - Keith N1AS - - K3 711 - -----Original Message----- If you are a "casual" cw op (or plan to be), then I would not get any "cw" filter. The 2.7kc roofing filter is already narrower than 99% of everything else available out there (for a roofing filter). _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
