Re: [Elecraft] K3 CW set up
Since the xtal filters in the K3 are roofing filters I'm going with the stock 2.7kHz filter, and just adding wider filters for 10m FM and broadcast AM reception. I'm betting that the DSP will provide all the narrow filtering I'll need. -- Julian, G4ILO K2 s/n: 392 K3 s/n: ???

Re: [Elecraft] K3 CW set up
John, I started back up with the QRP Fox Hunts on 40M. Sometimes there are strong sigs near where the packs are running so I use the 500 Hz filter. I also have the 200 Hz installed so if I really narrow the BW it comes on automatically. But its probably not needed unless there are S9+40 sigs very close to the operating frequency. I would recommend the 500 Hz roofing filter for best performance if you are only looking for one extra roofing filter in addition to the 2.7 kHz that comes with the K3. - 73, Greg - AB7R Whidbey Island WA NA-065 K3#0009 On Tue Nov 6 8:01 , [EMAIL PROTECTED] sent: How aie you K3 folks setting it up for QRP cw such as filters, etc? or, i.e. is the basic unit enough or do you do some add-ons?

Re: [Elecraft] K3 CW set up
I've settled on the 1 kHz roofing filter to start out with since it will allow a more expansive context when using the Dual-passband CW filter feature, something I'm really interested in.

Re: [Elecraft] K3 CW set up
I set up my K3 for RTTY and CW especially with the 8poles and 400 and 250. It depends what you want for CW - do you want to isolate signals or is a wider passband your normal procedure? I can tell you that the DSP does a very nice job narrowing the BW to isolate signals down to 100 or even 50 Hz (nice for isolating the response of a weak VO1 from the QRM of calling stations, for example.) But when you cross from 450 to 400 or 300 to 250 and the narrower roofing filter kicks in it is like a brick wall slams down. You really can hear the difference. Reducing interference from close stations is imperative in RTTY, I'm looking forward to trying it out in the next RTTY contest. I've also ordered the 1.8KHz filter for phone contests - especially SS phone! I have the 1.8KHz roofer for the FT1000D, it'll be interesting to compare them. hope this helps - jeff wk6i -- Jeff Stai [EMAIL PROTECTED] Twisted Oak Winery http://www.twistedoak.com/ Winery Blog http://www.elbloggotorcido.com/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
