Jim, AC4AV: I have not heard CW telemetry from RS-22 for over a week or so.
A couple days ago, I did hear some interesting audio, but caught the last few seconds before LOS.
RS-22 is sending short bursts of telemetry every 5 seconds on 435.352 MHz (FM)
This morning I could hear heavy downlink traffic. This data transmission system is called DOKA.
The DOKA modulation is PM with Manchester-encoded data on sidebands.
It uses 4800Bd data, one block contains 256 frames with sync wsequence and frame counter. The length of a RS-22 frame is 608 bit (76 byte).
