[WT-support] 100 Hz resolution

Richard,

Maybe I don't understand exactly what you're trying to do, or how.  What
SDR are you using?

Win-Test should always follow band changes on your K3. Win-Test should
never "move it back" unless something is configured incorrectly.

Maybe you can provide more details step-by-step, including screen shots of
wtDxTelnet configuration and all appropriate CW Skimmer settings.

All spots are accurate to no better than 100 Hz resolution in the band map,
whether coming from a local CW Skimmer or a DX Cluster, as that is the
maximum resolution provided in the TELNET feed.  This is close enough in
most cases.  If you only click on the Win-Test bandmap, this works fine.

Win-Test has never supported using the Skimmer Waterfall to move the
transceiver VFO.   If you enable the "Allow Skimmer Commands" checkbox in
wtDxTelnet, the CW Skimmer cursor will track your VFO movement as long as
Win-Test is running (it sends SKIMMER/QSY commands to Skimmer's TELNET
port).  You can use a program like HDSDR and OmniRig if you want to click
on a waterfall to move a VFO.

It should be possible for Win-Test to support Waterfall Bandmap software
<https://groups.io/g/waterfallbandmap> some day to integrate a waterfall
with the spots in a much more useful way than CW Skimmer.  It could also
recognize the "clicked on" messages generated by CW Skimmer.  But it
doesn't.

73,
Bob, N6TV
