During the 3:00 utc (82 degrees elevation) pass I did
not get over ISS L band uplink (10W, 35 elements).

Hello Marc,
Roger is right ... 145.825 is the easiest spot on 2M to wait for packets
from spacecraft. I have some ARISS packet tips on a web page at:

Subject: [amsat-bb] Re: FM Sat Packet
The "easiest" answer is to set your receiver on 145.825 and wait for ISS or
PCSAT to pass by...
ISS is currently tasked otherwise and PCSAT is only partially usable in
daylight, but they both will give you the "easiest" reception in the next
couple of weeks...
Turn your PASSALL ON for PCSAT as it is only sending partial packets (longer
story) and open your received buffer to record daily activity and check it
when you get a chance...
UNPROTO is the best way to use these two "easysats" in packet mode.
As for transmitting...see how well you hear them and what their schedule is
first...
Happy New Year!

Repeater active for 02.59utc UK / Europe Pass.
Poor access time, squelch setting seems higher. Only solid signal got
through today where as yesterday access was maintained with a much weaker /
scratchy signal into the box.
No other stations heard.

Nothing heared this time. I did not get over the L band uplink.
Close to max elevation while TXing I heared squelch open/close
but that was all.

Hi Greg,
these transformers and motors are rated for intermittent duty so getting
them stuck and left that way kills them, if memory serves
they pull about 1.7 amps running, and drop to about 1.2 amps stalled, 1.2amps
x 25v = 30 watts and over time that heat builds up and
fries the windings.
It's just a oddity of this particular type of ac motor that it behaves this
way, if it was another type or a dc motor you would see
the current rise that you expected and fuses would pop.
I found this out when I was making a add on card to my LVB tracker to
replace the G-5500 control box, I thought I would be slick
and add one of the PPTC resettable fuses on the motors, so I needed to know
the running current and locked current so I could pick
the right one, I was also surprised when the current dropped a little instead
of going up, and then doing some reading on the web
about dual winding AC motors that use a capacitor to phase shift the other
winding explained why this happens.

Ha, really... Thanks, I was "sure" it was the other way around.
So, if the current drops a little on a jam, why would it burn up either the
transformer or motor?

Hi!
I have not done much CW in recent years. The last time I worked
this mode was for the 2005 ARRL Sweepstakes CW contest, which did
wonders for getting comfortable with higher CW speeds. I tried it
once via satellite unsuccessfully a few months ago. I decided to
try CW on the SSB/FM side of AO-51 tonight, after a few calls in SSB
without responses. I sent DE WD9EWK a couple of times, and Glenn
AA5PK showed up. We made a quick QSO, and now I have 1 satellite CW
QSO in my log. Thanks, Glenn, for the contact. A QSL card will be
heading your way.
I know I could change my callsign, to eliminate the one big reason
I don't do CW much (the "K" at the end of my call). That was the
reason why my first attempt at satellite CW didn't work out - the
other station thought my callsign ended in a "W". Now that I have
a CW QSO via satellite in the log, I may just try to deal with the
"K" and see if I can start logging more satellite CW QSOs. More
satellite fun for the new year, to go along with just getting on the
air and also getting on from many different locations...
Happy 2009 to all, and 73!

That was three of trying this morning then Henk.
David and I heard a couple of carriers and that
was it. Don't know whether it was his carrier or
mine that lifted the squelch or not.
If I am still awake, I will try the next pass too.

Poor showing this morning for some reason, the worst result since 30
December.
One brief burst of carrier and that was it.
Henk - Happy to have tried and more than willing to try again tomorrow early
morning. Thank you for copying my signal on the earlier pass.
If anyone else wants a last try tomorrow let me know.
I will listen next pass, 06.09, but elevation probably too low for my Tx
antenna especially based on this mornings earlier results.

David

Hi Kevin,
So, my take-away here is that it's not the stall itself that is the problem;
the motor is practically designed to self-destruct. Simply running the rotor
back and forth enough times will do the same thing. In fact, probably worse,
given the higher draw.
One thing just occurred to me... AC current measurements assume a specific
phase relationship between voltage and current - power factor, I think they
call it. This is a highly inductive load, and the phase-shift capacitor
throws another unknown into the puzzle. I wonder if the two measurements you
took are real? It could be that you think that the running current is higher,
when it may just be a measurement error. How were they measured?
