For the station Grid EM77 that contacted me in this bird, could you please
advise your call sign I am breaking in a Kenwood TH D 72 and had ear phones
on with no recorder hooked up as yet.
Trying to figure that out.
So if any one does have me on that pass on a recording please advise. Would
be appreciated
Thanks

I'd like to suggest another factor. The early passes on Wednesday UTC have
been moving slowly later in time.
Last night's passes were after "my bedtime." So I was able to participate
only on this morning's two passes.
Perhaps someone could look at the passes for, say, the next six months, to
choose a UTC day where the passes
would be more balanced in "normal" awake times.
Another question: Are we restricted to a UTC day for the L/v operation?

It's always the same people anyway. Generally those are the same people who
spend all day everyday beside their radio so it doesn't matter what day
it's on. Weekends are where new people with their dual band rig decide to
give the birds a try typically, keeping U/v gives them more chances to make
a first QSO.
Personally, my vote goes to turning on the camera on the weekends so
everyone can be frustrated equally with how our volunteer command stations
operate.

Looks like your observation is spot on. SatNogs is tracking it at 436.793
- and it actually looks like (from the waterfall), that that half kHz may
be there, too.

Be aware that Satnogs ground stations frequency are only as accurate as the

As I reported on twitter last night, I was the only operator on the 0602z
pass. Nice, high, strong downlink, crickets. And, being a working stiff,
that was the only available pass for me.
Totally for going back to the weekend. Thank you Patrick

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.

I believe Mike is on to something here, this surprise mode change idea
sounds interesting. Perhaps our outstanding IT volunteers could code a
random number generator script that sends an email to the 2 command station
volunteers on a surprise day each week. It would be a requirement of the
position that those holding command station authority shall upon receiving
this email halt their other activity and command AO92 to L mode on the next
available pass. Exceptions of course could be made if any 2 directors
object via the social media format of their choosing. If the command
station volunteer misses this message then they shall forever be banned
from command station authority, and will be forced to wear the "brown
baofeng of shame" at every symposium thereafter.
Who's with me?

+1 for returning the AO-92 L/V mode change over the weekend.
While we all appreciate N8MH and the other command stations ops efforts to
switch the satellite mode, I still believe the Operations Team should
request help from other operators with the necessary equipment, and time,
in order to ease the burden of commanding our satellites. In almost 5 years
working sats, I have never seen such requests.
