calibration: FCTR and
external counter on TP1, select 28 MHz, match counters using CTRL-C22. [You
must re-run CAL PLL (on all bands) and CAL FIL (tweak all BFOs) before you'll
get any benefit out of the C22 change! ] |
VCO Align:
Frequency set to 4000.1, DMM to left side of R30). Adjust L30 for 6.0 Volts |
