I decided to try the same on 20m since 40m is relatively dead here. Using a 70 kHz SPAN and 400 Hz filter, after QSY I had NO signals falling outside my passband. I don't know what we're doing differently but I am simply aligning MKR A (in the Spectrum display only) which is 2 pixels wide with the signals in the Waterfall display directly below. I adjust REF LVL such that the waterfall background is relatively dark and weak signals are 1 pixel wide. I don't find it hard to align these but would actually prefer if MKR was 1 pixel wide instead of 2 (and I've told Alan that).

The advantage is that clicking on a decoder dot in Skimmer takes you to the *exact* zero-beat frequency. The downside is that Skimmer's "Softrock on IF" mode (which is what must be used on the K3) is limited to 24 kHz spans (although Page Up and Down allows you to jump these spans up or down the band quickly). IMHO the really unique advantage of Skimmer is that you can jump from one decoder dot to the next by simply using Up or Down arrows on the keyboard. This makes for extremely fast S&Ping up or down the band in contests. CT1BOH first described this below: http://lists.contesting.com/pipermail/skimmertalk/2008-November/000191.html This is perfectly legal for unassisted categories since Skimmer's Blind Mode is not displaying decoded calls. If the P3 can be made to do something similar this would overcome this weakness relative to Skimmer. The P3 has many other advantages such as 200 kHz span, better flexibility in controlling both VFO A and VFO B, etc. In the meantime, one workaround is to leave the K3 in CWT mode, click on the P3 signal and then tap SPOT for auto-tuning. However this still takes two keystrokes and requires that you at least get the signal inside your filter passband. I believe the P3 may eventually allow automatically sending the SPOT command to the K3 with its QSY command, but there are probably better ways to do this. I know Alan is very aware of this need and we'll just have to wait to see what he comes up with. 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-a-modest-proposal-for-QSY-tp5410950p5413246.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
