note:
Older versions YAESU FT817 have different values of the resistor
to the ACC connector for the +12V output.
10R is ok, older versions have 75R inside, so the ext. Display
didn't work.
Replace the resistor R1235 with an10R size 0504 (main unit backside
close to the ACC connector)
YAESU
FT817 controlled via bluetooth
Connect
bluetooth adapter (~10,00) to the ACC connector
for example:
Install software YO3GGX Pocket RXTX Pro (for ANDROID users
->PLAYSTORE)
