      I shut the system down and rebooted everything last night and even waited 10 minutes to power back on....Just in case. No change, my "Audio IF, Hz" Had to remain at 0 for the frequency to be correct.
      So this morning I fire everything back up and sure enough....Everything was off by 1700 HZ so I had to plug in 1700 to Audio IF. Nothing else had changed. It must be something between PSDR and Skimmer.
      SR is always turned off on PSDR but thanks for the tip.

      Make sure you do NOT have PSDR 'SR' enabled.....
      that will create the offset.

        The same thing happens to me. Usually the jump is by 1KHz. It's not an
        LP-PAN problem because the frequency offset of PowerSDR/IF is not
        affected. I sent mail to VE3NEA about it a couple of months ago but
        never got a reply.

            I just got another clue....When I call CQ, Skimmer displays my call as a CQ find about 800hz below the green arrow. I think it's picking up some spur from the LP-PAN. I've always seen these on PSDR's scope but it didn't matter.....So when I was finished calling CQ, Skimmer was off frequency again by the usual 1700 Hz.
            When it's off like this, I can click the signal from PSDR thus tunining it in and on Skimmer I can see the code but it's way off frequency. Clicking on the code changes the K3 by 830 HZ and of course I loose the signal. So now I have to change the Audio IF back to 1700 HZ.
            So Skimmer must be reacting to that spur somehow.

                Hi Steve - isn't this just a tad over the top? In the States, it's a
                long holiday weekend. I don't know if the same is true in Canada, but
                when you're dealing with a one-man outfit, and when it's a sideline
                business, you have to expect an occasional delay in response.

                    Thanks Ted.
                    There's always a defense team on these mail list. I've looked over all the post and see many unanswered questions. That's typical of freeware but $75 is at the top end so we tend to expect more.
                    I am impressed with Skimmer's ability to decode and I especially like the reverse beacon. I've directed several folks to it and everyone was impressed. There are lots of folks who want wider bandwidth for their use with LP-PAN and other systems but it seems the author has things locked in to the QSR-1 for whatever reason. I have not seen a good explanation for this other than it is a good way to sell QSR1s. Even then...If I had the QSR1 there are interface complications with other rigs so it would be much better if Skimmer could decode the entire 192 khz.

                    Hi n4lq, I have never used K3 myself, but I was told that the exact value of IF in this radio varies with time, e.g., when the user selects a different filter.

                          Alex: Yes...That was the problem. Changing the IF bandwidth causes the IF frequency to vary thus throwing off the skimmer display. I now remember something

                            Is it really solved in the W2UX version? I have been looking for a solution to the frequencies being wrong in Skimmer when the roofing filters change in the K3

                              Where do I find more information? Googling W2UX doesn't bring up much.

                              Yes...That was the problem. Changing the IF bandwidth causes the IF frequency to
                              vary thus throwing off the skimmer display. I now remember something about this
                              concering PowerSDR-IF and it was solved by W2UX in his version.

                                  Some misinformation here...

                                  1. LP-Bridge does include filter offset info:

                                  "SDR Linking... The following functions are currently linked between the K3 and the SDR software: VFO A, VFO B, Mode, IF Offset and TX/RX. The links are bidirectional, meaning that any change made on the SDR software will be reflected at the K3, and vice versa. In addition, LP-Bridge provides links for VFO B, K3 bandwidth and Preamp/Attenuator settings to allow the vertical scale in the SDR software to be re-adjusted whenever the K3 preamp or attenuator are activated. These require setting up an additional CAT interface port in the SDR software."

                                  http://www.telepostinc.com/LPB.html

                                  2. The K3 has filter offsets for 5-pole filters but no offset for 8-pole filters.

                                  3. Skimmer's Omni-Rig can only accept one offset.

                                  4. WU2X's latest version of PowerSDR does include offset corrections.

                                  "If you have selected the Elecraft K3 as your rig type, you don't need to put any values in for the IF Frequencies for each mode - leave them set to zero." (referring to PowerSDR...not Skimmer)


                                  To correct for the K3 offset issue with Skimmer, there are several potential solutions:

                                  1. Use only 8-pole filters which have zero offsets and thus do not change when switching filters.

                                  2. Keep track of which filter you are using and change the Skimmer > Settings > Radio > Audio IF setting manually when you switch filters. This isn't convenient but it's what I do. Since I use 500 Hz 8-poles in diversity 99% of the time on CW, it's not a huge problem for me.

                                  3. If Alex had time, it should be possible to read the K3 IF offsets via commands (as PowerSDR does) and correct the Audio IF settings automatically. However he's very busy and probably has higher priorities to worry about than this one.

                                  BTW I no longer use PowerSDR/HRD at all. I use only Skimmer directly with the K3, N1MM and LP-Bridge. For contesting and DX-ing on CW, I don't miss the PowerSDR/HRD combination at all, which takes quite a load off of my computer as well.

                                    3. Skimmer's Omni-Rig can only accept one offset.

                                    4. WU2X's latest version of PowerSDR does include offset corrections.

                                    "If you have selected the Elecraft K3 as your rig type, you don't need to put any values in for the IF Frequencies for each mode - leave them set to zero." (referring to PowerSDR...not Skimmer)

                                    To correct for the K3 offset issue with Skimmer, there are several potential solutions:

                                    1. Use only 8-pole filters which have zero offsets and thus do not change when switching filters.

                                    2. Keep track of which filter you are using and change the Skimmer > Settings > Radio > Audio IF setting manually when you switch filters. This isn't convenient but it's what I do. Since I use 500 Hz 8-poles in diversity 99% of the time on CW, it's not a huge problem for me.

                                    3. If Alex had time, it should be possible to read the K3 IF offsets via commands (as PowerSDR does) and correct the Audio IF settings automatically. However he's very busy and probably has higher priorities to worry about than this one.

                                    BTW I no longer use PowerSDR/HRD at all. I use only Skimmer directly with the K3, N1MM and LP-Bridge. For contesting and DX-ing on CW, I don't miss the PowerSDR/HRD combination at all, which takes quite a load off of my computer as well.

                                      1. LP-Bridge does include filter offset info:

                                      "SDR Linking... The following functions are currently linked between the K3
                                      and the SDR software: VFO A, VFO B, Mode, IF Offset and TX/RX. The links are
                                      bidirectional, meaning that any change made on the SDR software will be
                                      reflected at the K3, and vice versa. In addition, LP-Bridge provides links
                                      for VFO B, K3 bandwidth and Preamp/Attenuator settings to allow the vertical
                                      scale in the SDR software to be re-adjusted whenever the K3 preamp or
                                      attenuator are activated. These require setting up an additional CAT
                                      interface port in the SDR software."

                                      http://www.telepostinc.com/LPB.html

                                      2. The K3 has filter offsets for 5-pole filters but no offset for 8-pole
                                      filters.

                                        It's not a huge issue for me since 24 kHz covers the most interesting areas of the CW bands for me. Plus you can Page Up or Down very quickly if you want to check other areas. When contesting with Blind Skimmer, I jump (up or down) to the next decoder dot. When you do this the 24 kHz window is always centered on the green passband window, so it's always tracking you as you S&P up or down the band.

                                        It would be nice to have wider spans, but the advantages of Skimmer are so great compared to any other SDR waterfall, I'm willing to live with 24 kHz for those advantages. If you really want wider spans there are other alternatives like SDR-IQ, Perseus, QS1R, P3, etc. The P3 already has 200 kHz spans with higher promised for the future, and I would carefully watch what Elecraft does with that AUX DATA output on the rear. I can imagine it might make an SDR-IQ obsolete in the future.

                                            I contacted Larry N8LP and he reported:

                                              I contacted Larry N8LP and he reported:

                                              "One of many things on the LP-Bridge list. First I have to add the telnet interface, unfortunately ;-(

                                                Telnet is how LP speaks to Skimmer. No telnet, no correction.

                                                What does Telnet and Audio IF correction have in common? Sounds like 2 separate projects to me.

                                                  Lot more interoperability being squeezed out of skimmer than what it was designed with. A bit tough without that capability as part of the original feature set so most guys have to work around this and that as Alex is understandability not wanting to do a lot to the code on this older project. New fish to fry and all that...

                                                  Oh, I should have said more properly "Skimmer speaks to LP."

                                                  Telnet is how LP speaks to Skimmer. No telnet, no correction.

                                                  What does Telnet and Audio IF correction have in common? Sounds like 2 separate projects to me.

                                                    Well the freq. change isn't all that big a deal now that I understand whats happening. I've just got one 8 pole, 400 hz filter and the rest are 5 pole so I can either skip 8 pole and jump to the 200 hz, 5 pole or change out the other 2 filters.
                                                    When I look at Skimmer I think....Wouldn't it make sense to turn the display up vertically like most waterfalls? So using the video card's options, I rotated the display 90 degrees and dragged the screen out to the full width of the 19" monitor. Now I can see 15 khz instead of just 6 khz of the band. Of course there is the sideways mouse issue and reading calls is not so easy.

                                                    Steve,

                                                    Lot more interoperability being squeezed out of skimmer than what it was designed with. A bit tough without that capability as part of the original feature set so most guys have to work around this and that as Alex is understandability not wanting to do a lot to the code on this older project. New fish to fry and all that...

                                                    Oh, I should have said more properly "Skimmer speaks to LP."

                                                    Telnet is how LP speaks to Skimmer. No telnet, no correction.

                                                    What does Telnet and Audio IF correction have in common? Sounds like 2 separate projects to me.
