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.
