Wyatt,
Thanks very much for all the great contacts and new grids. You did a great
job! I appreciate it!
Jeff, NX9B and Kevin, N4UFO generously kept me on the loop every time during
your rover operation. It was an exciting hunting!
Thank you guys!

Asunto: [amsat-bb] Ac0ra trip
Well just another four hours of driving till we get home. Well I am riding
now but will drive the last stretch through Iowa. By the time we get home we
will have been on the road for about 22.5 hours.
Any way I just did the tally and I have 238 contacts in the log from 25
different grids and from 6 different states.
A few of the high lights of the trips as far as sat ops go was working vo52
from two grids while mobile. For the First three minutes of the pass I was
in dn91 then passed into dn90 and worked three station from each grid.
Also at the last minute I decided to take and hour detour north off of i80
to the en01/00 gridline just north of grand island to work quite a few
stations.
And to all those who worked me on fo29 while I was mobile I am sorry for the
weak signals. My half wave mobile whip got damaged early trip by a big bird
at 80mph and it never worked right after that. For a while it didn't work at
all but with some roadside repairs i got it working to get us through the
trip.
Also if you working me you might have noticed sometimes I signed mobile and
sometimes I signed portable. Well this was for a reason that is quite
obvious. When I signed my I was using my ft857 with halfwave mobile antenna
for 2m and three el arrow for 70cm. Mostly was semi duplex while mobile but
sometimes used the ft817 for rx.
When I signed portable I was using the ft897/817 pair with an arrow antenna
which performed flawlessly. Well all but my battery charger for the ft897
batteries stopped working which wasn't an issue because I had a back up
35amphr gelcel along. Charged everything while driving through inverter and
once in the hotel room.
If you want qsls for grids which I assume some will of you could send a sase
with the contacts you want with the grid I was In writen on the card that
would be good. It might take a little bit for cards to get back out as I
might need to get some made. But it shouldn't take more then a month or two.
Thanks to all who followed me along the trip!

You'd think I would have this figured out by now. I never paid very close
attention to exact antenna direction until now. I mean the satellite was
always within the beam pattern. I tried the SuM part of Satpc32. I am
thinking of trying some EME, and I looked up the boom of the yagi' and I was
about 8* high and maybe 10* to the right of the moon, still probably within
the half power point of the beams. This is where the obsessive part comes
along, should I use the moon as the "grand phooba" of calibration? Or
compass true/mag. I mean the moon is "pretty" consistent. As always the
collective thoughts of this bb are never wrong.

What I do ( and I'm not sure I'm right,but seems to work ) is to use the
North star to calibrate. I live at 41.2* latitude, so if I crank my
antennas to 41* elevation and point north 0* azimuth I should be pretty
close. I also live at 1* magnetic declination, not much so I don't worry
much about that. Now I don't do much EME as I don't have any power, but
I've monitored EME and this seems to get me pretty close. I will also be
glad to see what others do to calibrate.

Hi Bob,
I use the Sun, late in the afternoon. The satellite program tells me where
the Sun should be, and I aim the rotor to match. Then up on the roof I go,
to align the rotor mount so the shadow runs down the beam. Worked quite
well for aiming at AO-40.
Of course in the Pacific Cloudy West, you may have to wait awhile for a
clear day...

The North Star is the best. even tho it itself is a little off from
exactly North also. But less than a degree. About 0.6 degrees or so.
If that isn't accurate enough there are tables you can look up to learn
what we call cumulation of Polaris. This is a time when Polaris (AKA The
North Star) is directly above or below the pole. and then would give you
an exact AZ setting, then 6 hours before or later Polaris would be east
or west of the pole exactly and this would give you an exat elevation
setting.
Never use magnetic readings. depending where you live it can be a LOT off.

Only if your program is accurate and operating correctly. The Sun is not
a smooth mover, at say Noon, it is not due south in AZ all the time.

There's also the Heavens Above website, which will tell you exactly when
local Noon is. The Sun will be at 180 degrees Az at that time. The
disadvantage of this is that it will also be high in the sky, reducing
accuracy. Unless you're at a high latitude... Bob wins on this one.

Hello (again)...Is there a way (program) that one can predict when the
apogee of a given satellite will favor a given grid square? Specifically
FO29 varies from about 813 km to 1351km. One can potentially "stretch" the
footprint when it is at apogee.
