The only problem he might have with this is: (posted by Kent Frazier)"My
current hardware is an Icom IC2720 dual band in my personal vehicle with a
Comet C767 dual band antenna." , so he's mobile. He'll have to sync-up his
time via another means such as a wristwatch.
Kent, just to make sure, ARE you using your PC in your car to control your
radio??

Hello John,
Thanks for your query about LO-19.
Thanks to the good efferts of our AMSAT Operations VP, Drew KO4MA and his
establishment of the right contacts, a few weeks ago I spent some time
corresponding with the LUSAT/LO-19 team.?? They are a great bunch of hams, and
they are (rightfully so) very proud of their "old" bird.??
We came to the conclusion that the failure mode of LO-19 is quite different
from that of AO-16, and that any change from its current state of CW telemetry
would either be impossible, or sufficiently risky that it was best to "leave
well enough alone."? So, I think we can expect that LO-19 will continue to
report CW telemetry for a long time.? It's a great bird and its 18 years of
continous operations is an amazing feat.
Drew KO4MA has been attempting contact with the WO-18 folks.?? DO-17 isn't
such a likely candidate for doing much of anything...
Other thoughts...you can include IO-26 as being "nearly the same" as the
original microsats, Oscars 16/17/18/19.?? In fact, I have started?some
preliminary testing of IO-26.?? The testing is especially slow, and it will
take some time to sort out its current state (what works and what doesn't).?
Once we know that, we can begin to consider what function(s) IO-26 might
serve.? While we have no idea at the moment if it's feasible, in theory its
hardware could?permit being?reconfigured like AO-16.? We just don't know what
our options are for now.
Rest assured, we're working on it :)
73,
Mark Hammond N8MH

Good Afternoon, Everyone.
Last month, a question was posed about the possibility of reconfiguring
LUSAT/Oscar 19 in the "bent pipe" style that AO-16 is currently in. ?As I am
writing this, both AO-16 and LU-19 are overhead...and both have stellar
signals.
Is there any news/update as to whether or not this can be accomplished??
Upon reading the Satellite Handbook, it appears as though 16, 17, 18, and 19
were pretty much similar. ?If I am wrong, then I will stand as corrected,
but if 16 could be converted in such a fashion, what prevents 19?
Wishing for Spring!
John KB2HSH

Re Time Sync: The clock on my computer is currently synced with an internet
time server. It only varies by about 3 seconds from the atomic clock on the
wall.
I am not using the computer to control the radio. With the exception of this
morning, all my monitoring has been from the driveway of my house while
stationary. This morning I listened while taking my daughter to school.
The AMSAT Online Satellite Pass Predictions showed a pass of AO-51 for this
morning as follows (Times UTC):
29 Feb 08 13:55:12 00:07:29 277 8 318 20 14:02:41
I didn't hear anything on this pass. Could this be because the elevation was
only 8? I started listening at 13:50 and ended at 14:10 hearing nothing but
noise.
I'll try to listen for for the 20:19 pass which shows a maximum altitude of
75.

OOPS!!
I listed the pass prediction for ISS, not AO-51. Here is the correct AMSAT
Online Satellite Pass Prediction for AO-51 this morning:
29 Feb 08 13:58:51 00:13:47 20 44 110 179 14:12:38
I was trying to listen to both. I wanted to see if I could hear the ISS APRS
digipeater. AO-51 was tuned on one band and ISS on the other. Nothing but
noise from either. I'll concentrate on AO-51 now until I get a better
understanding of what is going on.

Kent:
We're lucky today to be able to do 'sanity checks' when we get no
results from the birds. This list will reply to such requests, but you
might find it is more slow than you'd like. If you'd like to know
right away if the bird was transmitting, you should look at
http://oscar.dcarr.org, which tabulates near-real-time reports from
observers around the world. This is especially handy for the mode of
AO-7.
Of course, this web resource depends on reliable reporting from people
like you and me.

McSoft has its own internet time client built in, I think its default
is off, just turn it on in administration, and set the update
interval to something reasonable, or get the free Tardis2000 time
sync software, if you are running a small network, set 1 machine to
check time from an atomic clock server, then have the accompanying (
also free ) client program called K9 on the other PC's, and it will
keep all PC's on the network time sync'd. Tardis and K9 hail from Dr
Who.. the Master and Servant!
