This is one of the original batch from ebay and consists of 2 separate amplifiers in a single case, each are capable of more than 100 watts on 2.4Ghz each.
I have taken the modified PA module complete with Arduino bias control and refitted back in to the PA case. I have then tested the unit and confirm both PAs are working. It is ready to go on air when supplied with 50v but will require the coloured PTT wires from the Arduino to be controlled by your PTT.
