> The frequency is the same used in the telemetry commands and telemetry channel
> (435.100 MHz) and the activation of the digipeater function is scheduled every
> week during the weekends (from Friday at 00:01 UTC to Sunday at 23:59 UTC).
> The software kit can be downloaded from the same web page. The satellite digipeater
> implements a store-and-forward message service and works at 435.310MHz (U/L and D/L).
> GreenCube Digipeater package
> Here is the test version:
> There you can find client application and two modems for SSB and FM mode.
> UZ7HO, I guess SSB version will be preferable because you can use
> additional decoders (see "Modem" settings) and no decoupling issue because the
> FSK 1200bd signal is quite "low-frequency". Just make sure that you use correct
> offset in USB mode (for 1600Hz should be -1.6 KHz).
> UZ7HO, I noticed that the original SSB modem has 350mS TXDelay. I fixed the
> default TXDelay value to 400mS, since it makes sense for better AFC.
> Please check the following settings:
> Additional pairs: 2 or more (up to 8)
> TXDelay: 400
> Take care!
