RE: STUPID DIGITAL QUESTION



This is still to be determined since it requires changing to the high power
transmitter and we are currently assessing the risk of doing this in light
of the transmitter problems that we have experienced since launch.

The problem with TX0 has reduced considerably, and is largely insignificant,
however if it is related to transmitter power then increasing the power may
not be desirable.

38k4 does work with TX0, however the link margin is not particularly good.

Cheers
Chris

In the interest of a challenge,  when can we expect to see some scheduled
38k4 
downlink activity on TMSat  ;-)
