If you want the 2.8KHz, you can swop out the 2.7 and replace with 2.8 at a discounted price On 10/12/07 17:13, Mike Geddes [EMAIL PROTECTED] sent: My K3/100 has been on order for a couple of weeks now.

Re: [Elecraft] Recommended K3/100 filters
FWIW I hear the difference as the 250Hz kicks in as I change the bandwidth from 300Hz down to 250Hz, the difference is (I think) less DSP noise - maybe Lyle can explain. It's not a problem at all. For SSB I have the 1.8kHz and that really is a great filter, I was listening on 40m a few hours ago with 1.6kHz bandwidth - very, very good. I agree about 1kHz for tuning about on CW.

Re: [Elecraft] Recommended K3/100 filters
Hi Mike, Along with others here is my recommendation. You work mostly SSB very little CW and no contesting to speak of. I don't see why you would want a CW filter more narrow than 1khz. If you need to be tighter than that, probably not, but you can narrow it all down with the DSP. OTOH if you have the bux, go for it all. de Joe, aa4nn - Original Message - From: Mike Geddes [EMAIL PROTECTED] To: Elecraft elecraft@mailman.qth.net Sent: Monday, December 10, 2007 12:13 PM Subject: [Elecraft] Recommended K3/100 filters My K3/100 has been on order for a couple of weeks now.

There is certainly a noticeable improvement when the bandwidth is reduced beyond the 400 Hz mark and the narrow filter is automatically switched in. For CW I wouldn't want to rely solely on the 2.8 KHz filter. Dave, Perhaps you can comment on what sort of improvement was noted when the 400 Hz filter was switched in. Noise? Steeper skirt selectivity? Impulse response (ringing)? IM products? Thanks 73, Terry N6RY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
