Hermes-Lite 2 - Band data

With my Hermes-Lite 2 (HL2), I wanted to be able to control my Juma PA1000 and my CAT controlled vertical antenna band changes.
My HL2 is from before the newer add-on board was available, so you had to make your own solution.
It's relatively easy using the HL2's serial port to decode the current frequency of the HL2, convert that to bands and convert that to BCD data as per openHPSDR/Anan.
I also coded it to work with a Hardrock 50 Linear Amplifier before I got my Juma PA1000.
The HL2 serial port is only 2v5 and so I use an Arduino Pro Mini, 3v3 powered internally from the HL2 as per pic below (click pics to go SUPERSIZE)

I use 'software serial' on the Arduino Pro Mini and set the internal pull up to get reliable serial decoding from the HL2.

The mod involves removing the original 20 way joiner and using new headers soldered to the PCB as in the pics.  All wiring on the PCB is simple point-to-point as required.

My CAT controlled Juma amp and vertical antenna is on my QRZ page...
