[amsat-bb] VO-52 loud and clear on orbit Nr 37097 over Europe

[i8cvs]

Hi All,

The VO-52 Dutch transponder was working very well on the ascending
orbit Nr 37097 with max elevation of about 30° from my JN70ES

Recorded the whole orbit on magnetic tape with recorder REVOX-A77

Worked only IW6OVD and IZ8JHD and made a long chat with those
Ham friends.

My uplink power was 30 watt on a 10 turns Helix antenna RHCP

No other SSB stations were available on the passband because
probably they were not informed about the recovery of VO-52

At the end of the orbit at 2° elevation only two stations were active
from Russia.

The transponder modulation is OK and very linear even if a
comparative report with the Indian transponder can be available
only in the next few days.

Signal strength: CW Beacon is very clear without chirps and signals
linearity on the passband seems to be comparable with that of the
Indian Transponder

The best polarization in 2 meters downlink is LHCP as with
experienced with the Indian Transponder.(same antennas)

The lession learned (in my opinion) from AMSAT-India and ISRO is
the following one:

"If you want a satellite to communicate it should be simple
and have only one mode of operation and redundant trasponders".

Critical report: ISRO and AMSAT-India should have more than
only one control station.

Congratulations to ISRO, to AMSAT-India and to William PE1RAH
