    bob85 schematic

    Honestly it's hard to predict what value r2 and r4 have without knowing the part number of the pwm ICs. PWM - Pulse Width Modulation for DC Motor Speed and LED Brightness - Robot Room this website points to a 10k pot for both r2 and r4 but says you need two diodes to vary the on and off times...

    Uniden 980 SSB - Ranger SRA-117A echo mic

    Ranger RG99 and President Jackson

    All the exports put out about 25wssb and 8watt am/fm. that's the most you should run them at to avoid damage to the board. Some have bigger finals than others but the boards are the same.

    I never had a jackson but I do have an export grant. The export jacksons had fm and 5 or 6 bands , im not sure and the export grant had 3 and fm.

    Ranger RG99 and President Jackson

    AFAIK no clones of the jackson were made. It's probably a clone of a president grant, like every other 10 meter export.
