[WT-support] TRX Control for FT990

[Franta Bendl]

Hi Olivier,

I'm sorry to be a trouble to you. I'm affraid there is no other way for me to 
use WT with FT990 because the YAESU stopped meanwhile the support with the 
PROMs updates.

You are right, the problem is the amount of the data. The radio needs about 
2,5 seconds (1492 bytes over 4800 Bd) to send all the data and the reading of 
only the subset of them is not possible.

The last question before I give up. Do you see any easy(!!!) possibility to 
modify the TRX-control in WT for special FT990 (FT990.2) in such way, that 
only commands (band change) will be sent from WT to TRX but no data will be 
read from TRX? This solution would make me happy.
