Doppler measurements show that Thybolt 1 and 2 are
the objects 54363 and 54364.
Current separation: 1 s, so
it is not yet possible to determine which is which.

CW beacon frequencies:
Thybolt 1: 435.35447 MHz and Thybolt 2: 435.3522 MHz.

Nothing received on the telemetry frequency 436.175 MHz,
but that downlink is probably only active when in range of
India.

Al further (telemetry) information is available on this page:

Sanjay had posted that the satellite was functional. We hope it will be released for amateurs. 
Does anybody have details of the telemetry/data format and modulation?

In spite monitored for many passes, no signal detected on the FSK nor CW beacon QRG this side.
