I just purchased a CPI CP2000 it’s up and running but it only has a 1 watt carrier. It willmodulate to about 5. On sideband I see about 10-12.
The question is does anyone know that to adjust for the am carrier? Also the modulation is a bit low. Any help would be appreciated.
 

  1. Peak L204, L202, L203, L205, and L201 in that order for maximum power output on CH 20. Adjust 8205 to maintain 4-watt carrier output. Check output power balance on Ch 1, 20, and 40. If this power varies more than 0.5 watts from Ch 1 to 40 complete the following. Slightly adjust L204 for maximum power on Ch 1 and L205 on Ch 40. Check power balance. Re-check 4-watt level and adjust 8205 if required.
  2. Turn to LSB mode and check power level with limiting 1 kHz modulation. It should be at least lOw.
  3. Set front panel meter to read 4w with no modulation on AM, Ch 20 using TX MTR CAL pot 8557 located on the Interface Board (73043). There is a small hole through the circuit board to allow adjustment from the backside.
