[amsat-bb] AO92 L/V mode??

[Jeff]

I agree with Patrick on moving the AO-91 L/V mode back to the weekends. Last
couple of weeks there have been only 3 or 4 people working the mid morning
L/V passes...

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!
