I work 80M most every night. 4 states shy of WAS on JT65, 25 states shy of WAS on JT9. Only 4 countries though (compared to 62 countries on 10m and 15m). I've never seen any other modes show up in the 3.576+3.5kHz band while I was operating so I'm under the impression we aren't interfering with anything. This is, of course, anecdotal. Has anybody complained? And if we don't coordinate such a change with other JT65 software packages all we do is confuse a lot of people don't we?

The RSGB specify 3580 - 3600 for narrow band modes with the top 10kHz allowing automated stations. They also specify USB dial QRG of 3580.15 for PSK31. So that would seem to preclude 3580 because of existing PSK31 activity. OTOH 3586 is going to cover most of the available RTTY bandwidth for non-automated stations so neither is perfect. If the PSK31 activity really is at 3580.15 + DT then 3586 may be best. I have little on-air experience because I hear very little on 80m due to severe local 24/7 QRM. > > -- Joe, K1JT 73 Bill G4WJS. ---------------------------------------------------------------------------- -- Comprehensive Server Monitoring with Site24x7.
