Ok, .08 KC is 80 Hz, right?

Assuming that you haven't added a CR-502 crystal oven, the station's 
specifications on frequency stability is:
"+/- 7 ppm from 1 min to 60 min after power on".

If f=50 MHz that would be +/- 50 * 7 = +/- 350 Hz.
So 80 Hz off seems to be well within the specifications of the station.
