Hi,

As I would like to take advantage of the recent increase in
the 40m allocation here in the UK, I wonder if anyone has made
any sense of the diode table (D8 - D12) on the TS-850S digital
board schematic. This as far as I can see determines the
destination region and thus the rig's operating band limits.

I know that it is possible to change the existing arrangement
to give general coverage to the transmitter but would rather not
do that. Initially I did a hex dump of the ROM but found it too
big a task to decode without experience with the particular
processor code - a uPD78C10.
