think that many here was like me and have to handle multiple transvetrter problem when switch of band
by need to swap PLL / IF and PLL reference ..
during holiday i got nice idea and put it into practice ,take a custom relay board tie to a raspberry-PI for web interface
ther day anyone have tablet / smartphone or laptop during operation
so i start by DC-DC for suply the pi whit 5.1Volt and 3.3v then 6 RF-relay for IF , 6 for PTT line and add 6 output distribution 10Mhz for PLL
finally i add python code for Talk to my Flex-6500 radio via telnet and got VFO frequency for extract band data so in auto mode it completely automated
just like my radio spam from 160m to 10ghz
i put all detail including source and Gerber on my blog (i use forum as blog for better management and close user registration)
that code may change for adapt to any radio CAT interface via PI USB to serial to internal TTL serial port
i plant to make version for my FT-817ND soon ...
