Orion Internal Power Adjustment
From the Ten-Tec Reflector October 9, 2006
There are three 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.
