OOPS! Well we saw 12 FD sites logged onto the CQSRVR but after seeing no
return-CQ's from anyone else, I ased the author and around midnight he found
a glitch and all of the CQSRVR re-transmitted messages were all stuck at the
server!
So that explains why we all got ACKS and saw that our messages had gone out,
but they hadn't and so none of us were seeing anything. It is fixed now.
But too late for this fielday.
Anyway, anytime you have a regional, national or global event, don't forget
you can use the CQSRVR for any such global message group. Just put CQ GROUP
as the first two words of any message and everyone else using the same GROUP
will see them. For SCOUTS all over the world, try the CQ SCOUTS group
during your campouts.
See details http://aprs.org/cqsrvr.html

Every FD site will usually have APRS on line. Remember, you can contact any
other FD site in the world on your APRS channel. (144.39 in North America).
Just send them an APRS text message.
Of course, this assumes you know their callsign. To facilitate learning who
else is on the air, send a CQ FD message to the APRS CQSERVER and your CQ
will go to every other CQ FD site on the planet. This has nothing to do
with FD rules and points. It is just a way to have fun and be able to
contact any FD site without knowing apriori their calling freq.
Just send an APRS message to CQSRVR and make the first two words of the
message be CQ FD .... for example, "CQ FD from Bob in Annapolis, MD". These
do not count for points, but are a great way to have ham radio fun with
other sites.
This will log you onto the CQ FD message group and from then on, you will
get ALL OTHER such messages from all other such stations. When you DO see
an incoming CQ FD message, now then you know their callsign and can MESSAGE
THEM DIRECTLY from then on.
To keep the load down, you can only send one CQ FD message once every 30
minutes, but you will remain logged on for up to 12 hours. After no
activity, you will be dropped.
Oh, for more info about APRS and Field Day, see http://aprs.org/cqsrvr.html

On Saturday, I was at around 2600-3200 ft elevation going through
Skyline Drive in Northern Virginia. I hadn't planned on working any
satellite passes since I was a portable station and not participating
in Field Day, but I stopped to listen to two AO-27 passes in the
afternoon.
The first pass, I was facing the west side of the mountains.
Amazingly, I heard 4 stations trying to get into AO-27 on the uplink.
I was hearing them direct on 145.85. The funny thing is, not one of
them ever was picked up by AO-27. Secondly, 2 of the 4 stations kept
giving their callsign over and over from AOS to LOS, even with AO-27
being on a seven minute timer. This tells me a couple of things: 1.
They don't know how AO-27 operates and 2. They apparently weren't
listening to the bird. I tried calling two of the strongest stations
on 145.85 after the pass, thinking they might be listening. Nope. I
never heard a response. Makes me wonder how many people leave the
volume up on the uplink side of their setup (if running full duplex.)
The second pass, I was pleased to hear several "5 land" stations
making contacts through the madness. However, I heard several
different stations on the uplink. This time it was the usual variety
of "hello hello hello" and "test 1 2 3." Again, I was hearing this
trash all on the uplink 145.85... The sad part is, I never heard a
callsign. It sounded like 2-3 different stations trying than on the
first pass.
I realize the satellite hears a lot more crap than I could ever hear
at 3200 feet, but it was a very interesting perspective I've not
encountered before. I have been in areas when other stations (local)
were on the birds, but this is different -- one of the stations I
heard on the uplink was 200+ miles away.

Does anyone know if there are any plans for a 9600bd Pacsat in the near

I dont't know, but I usually have zero trouble working VO-52 during Field
Day, but this year I never heard even a peep from it on about a dozen
passes that I tried. It felt almost as if the satellite was not there or
the transponder was off. Probably an equipment problem on my end, but I was
able to hear (but not work) AO-27 and FO-29 a few times, so I know I at
least had my Android phone set up properly for making pass predictions, and
they also matched the pass predictions on AMSAT.ORG online. So, unlike
prior years, when I've done stupid things like not correct for Daylight
Saving Time or updated the station coordinates, I know I at least had those
major goofs prevented. But I was shocked and disappointed that I could not
even hear the slightest bit of activity or signal return this past weekend.
Like I said, this has always been an excellent, reliable linear
transponder, so I was particularly surprised...

There was a ton of Field Day activity on VO-52 this year. I had no
problem making contacts for K6AA.
FO-29 also preformed very well this year on the passes I was on.
Poor old AO-7 was getting the daylights hammered out of her, and MANY
station were running WAY too much power.
If I can get an S9 signal back running 5 Watts with modest antennas, why
oh why do people run so much power the poor bird FM's?
Oh, well......

Must have been a hardware issue at your end, as VO-52 was quite active for
Field Day. Remember, its downlink is on 2 meters, while AO-27 and FO-29
downlink on 70cm, so hearing them would tell you nothing about your ability
to hear VO-52 (or not).

Does anyone know offhand whether the "guts" of any particular past or
present Yaesu rotor are a direct replacement for those of a G-5400B azimuth
rotor? I sent mine to Yaesu for an overhaul, and they returned it saying
parts were no longer available...

W5MSQ (MoSQrpitos - Houston QRP Club) had six VO-52 contacts during Field
Day. Doppler was an issue plus our QRP ops, but no odd occurances. AO-07 was
better for us with 13 contacts. We were ready for Mode A on AO-07, but it
did not happen. No problems!

There is no good reason for anything to be anywhere... therefore, anything

I also can confirm VO-52 was active, but I had to use an amplifier during
Field Day, with everyone using power it left my signal in the noise without
it.

Hi George,
I had a lot of difficulty finding this information as well -- in my
case, as to whether a G-5500 could directly use G-5400 parts. Yaesu
says "no", and it was hard to find those with direct experience in
parts swap.
It may be possible to overhaul the rotor yourself, depending on what's
damaged. I've regreased mine, repaired the motor, cleaned the brake,
realigned the sensors, etc. Photos in the links below (for the 5500
but 5400 is similar). The process is rather involved, but if you have
lots of patience, it might be possible get the thing running again.
