[JRC] JST245 Band info decoding...

[Fabio IZ4AFW]

Hi guys,
    I am going to build a microprocessor-controlled antenna switch, 
to automatically switch my antennas when I change bands.
Originally my idea was getting band data from the PC (running 
Logger32 and/or Writelog), available on the parallel port, but 
actually I am thinking that the very same data should be somewhere 
available from the radio (JST-245) itself.
Unfortunately, the task seems to be more difficult than what I 
originally thought, because in this case we don't have a separate 
connector with band data (like in some Yaesu rigs, I think).
Anyway, I think that the data should be available, because if you 
connect a JRL-2000F linear amplifier that one can be tuned remotely 
from the '245, so it has to know the frequency.
Looking at the various connectors available on the back of the '245, 
I noticed a TXD and RXD pin in the Linear Amp connector, respectively 
"Bus line output" and "Bus line input". Could the info be here?

Does anyone have more info on this, please?
Thanks a lot in advance,
73
