Although Space-Track public relations are issued as the point,
OBJECT Number of PRISM 'B', not 'J', was shown with some proof.
It seems to be better to think that TLE is not fluid decision

If it cost $4,000,000 to launch a HEO we would have put one, possibly
two of them up since AO-40. We would at least be building the second.
Also $500,000 will barely cover the cost of the solar panels. It will
not cover the cost of the motor.
Dream on Macduff!

I had only a 8 degr elevation pass first and used both TLE for analyzing the
Well, it seems my assumption was right - seems we have to change the TLE for
PRISM to OBJECT J.
After this second pass with higher elevation (32 degr) I am sure that PRISM
is OBJECT J.

I had a pretty high pass early last night and heard nothing here in FN13....
Left the radio on and around 2100-2130 local heard a bunch of packets, some strong, some not. Not sure whether anyone was digipeating or not, cound not get UISS up and running fast enough before LOS.

- and I just listened in on the 0305z pass here from Huntsville...
I heard some packets, but couldn't decode anything.
Also don't see any current beacons via findu .. ..
Signal seemed pretty weak.
Any other reports ? Maybe I just got out of practice .?.

Assuming I am not interfering with anyone,
I am going to attempt a QRP SSTV transmission
from Hawaii at 0348Z today (01/28/09 UTC date)
via AO-51. Several west coast states should
be within the footprint. I will be using a Yaesu-
VX-7R with a homebrew Yagi. Please feel free
to listen in and I'd appreciate any feedback
(good or bad!)

I don't know what time you are referring to on AO-51.
The first pass on the west coast (01:04Z) was OK,
Had exchanges with KE5GDB and VE7VW with no
problems. Good pictures both ways.
The second pass was completely quiet. I called on voice
several times and sent CQ pictures with no reply
I did hear some Spanish voices in there a couple of times,
and a couple of other unidentified voice transmissions.
