Could the robots manage a closeup or high quality photo of the physical
condition of Oscar 40, just to stir the pot? I must guess that a great many
interested minds would be highly motivated and inspired by such a report!
Imagine how amazing it would be to know such things as the spin and

the time?

Not an AMSAT-NA member? Join now to support the amate
mes as having been
heard(telemetry only) on the "oscar.dcarr.org" site inside their database,
using Mode-S.
I am wondering if it is worthwhile to listen for this beacon (using my newly
installed BBQ-grid antenna), or is it definitely not making any noise?

girl, or Informator-1/RS-14 which were both directly overhead and whose
dopper-shifts were similar at the time... I confirmed it to be definitely
coming from AO-7.
As I push "send" the carrier is still clear at 3.5 degrees over the north
pole...

I probably would not have heard it then even if I tried... I don't hear well on
29MHz ;)
Is it known to beacon on Mode-A?

Another observation from DO33 (yo Bernhardt), I've always had trouble

completely different from that which predicts simple satellites around one

Although I'm nearly deaf on s-band, I did hear activity just now, about
12KHz below where Orbitron was telling me to tune.

Hi All,
Is RS-15 sending telemetry? I see that the pattern is different, nearly
constantly on on this pass as I type. I just can't hear well enough
today(local qrm) to tell what it is.

In my sub-urban QTH, I can hear nothing EXCEPT wifi noise starting right at
2401.025MHz in all directions. I'm planning to optimise my BBQ grill/3733
antenna in order to improve off-axis rejection, and hopefully the noise -
without having too sharp of pattern for manual tracking of AO-51. I'm

Thanks for the informative reply!
