Hi all,

I believe RS-30 is NOT OBJECT C (NORAD 32955).

I compared both TLE OBJECT A (NORAD 32953) and OBJECT C with a small
software. This script calculate the doppler frequency (fn= 435.315MHz). In
even seconds the software is controlling my FT736R with TLE OBJ A and in odd
seconds with TLE OBJ C.
Now I analyze the audio signal with common spectrum analyzer software.

You can see the graph here: http://dk3wn.info/images/rs30_compare_a_c.jpg

Audio frequency with OBJ C is drifting away in direction TCA. OBJ A provide
a constant audio without deviations.

73, Mike
