Re: Video of indoor, ultra-cheap cubesat operations



This morning I used the same setup to listen to a 2 deg. max elevation
pass of LO-19. Its signal is stronger, of course, but it probably
would be less well-suited to demonstration because it sends telemetry
periodically, not continuously. It is easy to lose the signal in the
doppler as the telemetry goes silent. However, with a practiced hand,
familiar with the period of the LO-19 telemetry it is quite possible
to record 559-ish copy from this bird without a preamp and with a
directly-attached 1/4 wave vertical.

I wonder if one could design a circularly-polarized antenna for 435
MHz that directly attached to the BNC and could be supported by an
FT-817...
