A friend of mine has a VXR7000 UHF 450-470 Mhz that was donated to use on the local ham club. He was able to program it via the windows software fine, but now only has 700 MW output power. Is there a tunign procedure that needs to be done to get it to work on the ham bands ?

If it has an internal duplexer,it will need re tuning.
Did it make correct power on it's original freq?
