[amsat-bb] AO-07, orbit 26364, Mode B

[Michael Fletcher <oh2aue@xxxxxxxxx>]

Hi all,

A0-07 loud and clear on orbit 26364
using FT290R portable with 4 element
yagi. Again copiable with a whip too.
Very clear telemetry, but several 
weird signals in the passband considerably
louder than the beacon. They sounded 
a bit like some kind of telemetry
signals (s/c over Greenland at the time).
Couple of European stations on SSB, one
on CW. The beacon telemetry CW was 
superimposed clearly on the loud
buzzy carriers, sounding like cross-
modulation due to severe uplink levels...

I wonder if the beacon TX is sharing the
common TX PA ?

Also, looking at an old photo of AO-07,
it looks like the 10 m antenna was 
spring loaded inside the s/c with pyro-
cutters to release it ? 

No wonder the 10 m beacon comes in so
well :-)

Also wondering if there was some kind of 
gravity boom experiment embedded in this ;-)
