    Another decent evening with few heard or perhaps the band is going long early; solar flux 75, A index 3?? Where is everyone???

    I did make one contact late afternoon but QSB with that rushing atmos. noise is still prevalent up here.

    I was on for quite a while.
    The early part had ssb jamming but they got tired or went to steal their kids candy.
    I worked someone running a swan 500 rig (carrier and one sideband) that did not sound that bad.
    First time I ever worked a swan rig on AM.

    I think the problem may be the band going long. 75m activity consists largely of roundtable groups, with stations all located within regions of a few hundred miles of each other. When the band goes long, the normal stations can't hear each other, and no-one attempts to venture out and start a QSO beyond their usual group. This is probably even more true with SSB than with AM. Since the beginning of this current season as the summer QRN diminishes, I have noticed a dearth of activity with both modes. Activity is also down on 160m, which should be at its best over a radius of a few hundred miles when 75m has gone long.

    Don has been filling-in for the late WA3PUN and W5PYT, night owls extraordinare, who could be counted upon to carry the airwaves all through the night, in all time zones.

    And from what I have heard, he really tests the duty cycle of his transmitters!

    Well, we don't do all this building and modifying for a push to talk QSO. If we wanted that we'd go get on the 2 meter repeater.
