Please this is just a technical matter :-)
Here this afternoon with Yubileiny AOS at 1430 UTC and
AO-51 with AOS at 1441 UTC in Copenhagen, the downlink
spectrum of Yubileiny was strong when listening to
the AO-51 frequency.
Yubileiny is on 435.315 MHz and AO-51 on 435.300 MHz.
During some of the pass they were at the same Az. angle.
Since their orbit is much different it will change over the year.
The spectrum from Yubileiny is very broad when transmitting
the APT like modulation. Also the signal is very strong.
It helped to use FM Narrow on the IC-910.
I still hope they have included a transponder in Yubileiny.
