7. Adjust LOAD control to place the illuminated TUNE LED at the “V” mark on
the TUNE scale.
8. Repeat steps 6 and 7 at least twice.
9. Increase excitation until 99 output is about 1500 watts.
10. Repeat steps 6 and 7 at least twice.
11. Touch up TUNE for maximum power output.
The ALPHA 99 is now correctly tuned to deliver 1500 watts RF output on SSB, CW,
FSK, SSTV and FM. The TUNE LED normally fluctuates during modulation or
keying. Illumination of the first red LED on the RF OUTPUT bargraph indicates
output has exceeded 1500 watts.
To operate at reduced power in any mode, decrease drive (i.e. transceiver power
output) and doublecheck all tune settings for efficient and RF-clean operation.
