Hi Bill, See blow.

The main bands where I've seen WSPR-15 used is on the MF / LF bands: 0.136, 0.4742, 1.8366, You can see the activity here: http://wsprnet.org/drupal/wsprnet/activity > 2) Does JT4 and the JT65 modes on VHF and up share a dial frequency?

Joe or the other VHF/UHF + guys will have to answer that, but I do know, the amount of bandwidth is huge, and QSO's are normally coordinated / scheduled ahead of time. This is one site that is used to coordinate: http://www.chris.org/cgi-bin/jt65emeA > 3) It turns out that it is easier to adjust the dial frequency to the > nearest configured working frequency when changing modes, I'm not sure what your meaning here. > 4) as there can, and will be, separate dial frequencies for JT65A and > JT9 on HF; this makes the +2 kHz check box redundant. I don't think I've ever used the 2Khz box, but then again, my rig has a variable width DSP filter. I would think, those rigs that cannot open their filter up past 2.4Khz would not be able to work JT65 and JT9 anyway and the 2Khz may be just a quick shift for them. > 5) I could leave the dial frequency untouched when changing modes but I > can't see a compelling reason not to change it when the target mode has > a different working frequency. As far as I can tell, there's only a couple bands that share the same space with WSPR. As for the shared JT65 v.s. JT9 goes, seem like setting the rig for the JT65 frequency seems the most appropriate, but everyone operates a bit differently. > > Comments and suggestions? > > 73 > Bill > G4WJS. 73's Greg, KI7MT ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ wsjt-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/wsjt-devel
