Mark,
A few months have passed since this discussion. Based on activity I
have seen since that time, it appears that L/V activity on the Tuesday
nights and Wednesday mornings dropped, compared to the previous
schedule on Saturday nights and Sunday mornings. The only times I saw
activity that approached the previous weekend schedule were around
Christmas and New Year's Day which fell on Wednesdays.
I think it is appropriate to consider moving the L/V activity back to
weekends. There are many with new IC-9700s that might have an easier
time trying L/V on a weekend, rather than a late weeknight or a
weekday morning, along with others trying all sorts of combinations of
radio and antenna for the 1.2 GHz uplink. I'm still enjoying the
Alinco DJ-G7T HT with a 10-element Yagi for my L-band uplink,
sometimes dropping from 1W "high power" on that band to 300mW.
As for the previous experimenter's activities on AO-51... those ran
for a week at a time. After AO-40, I think running those different
modes for a week at a time on an LEO satellite like AO-51 was better
than simply scheduling one day a week. You and Drew may have had to
put AO-51 into a mode like V/S, and then put the satellite back into
its normal mode, where AO-92 automatically switches from L/V to U/V
after 24 hours. I enjoyed V/S in those days, even with the need to
adjust for Doppler on the 2.4 GHz downlink almost constantly for 10
to 15 minutes, along with the cross-mode V/U where we had to transmit
in SSB or CW to be heard on the FM downlink. I worked a couple of
stations one year during Straight Key Night on AO-51 that way.
73!
