There are threee adjustments on A5 board (under speaker):
R20 marked "PWR" calibrates forward power measurement
R21 marked "REF" calibrates reflected power measurement
R179 marked "ALC SET" calibrates actual output power
Adjusting R179:
* connect external power meter and dummy load;
* set TX power to 100 W using MULTI knob;
* press TUNE, then PWR and adjust "ALC SET" for 100 W on the external power meter.
According to the schematics, A5 board is the same as on original Orion.
