Hope Oscar 68 (XW-1)

I have yet to hear from Delfi-C3 again, but in the mean time below is some CW telemetry data from HO-68 decoded with MixW on Friday (10 June 2011). According to one of the Delfi-C3 team members the CubeSat’s transmitter drops out intermittently and functionality is only restored once the spacecraft goes through eclipse and resets (Delfi-C3 has no batteries on board). Cape Town is its last `stop’ before the spacecraft goes into eclipse again so the likelihood of its transmitter having dropped out by the time it is over head is large, I guess.

I have also experienced quite a bit of interference around 145.870 MHz, the frequency at which the primary telemetry downlink is for Delfi-C3.

I have still to try and decode the messages below, but here they are in anycase. Most of the payloads on HO-68 is non-operational but the CW beacon is still active at 435.7900 MHz.

In the next week or two I will try to start setting up our two TNCs and find some satellites with active data/packet payloads to test them. I might also start posting some information and pictures on our equipment and current setup. Last week we also received our SignaLink USB sound card.
