Bob, what i would do is get a separate rx and one of those frequency
standards that used to be available (don't know if they still are or not)
that consisted of a 1 mhz xtal oscillator in a small box with a 2 or 3 ft.
whip coming out of the top. put the rig and rx on cw and on harmonic freq.
and zero beat both to standard. tx on rig under test into dummy load and
observe frequency difference on separate rx, or zero beat 2nd rx to freq.
standard, tx cw sig from rig under test and move it to zero beat in 2nd rx,
then unkey tx and observe where freq. standard is on transceiver's rx. Note that the standard doesn't have to be rock steady or accurate--just not drifting a whole lot over time so that during the minute it takes to do the test it hasn't drifted. Since you are measuring relative to what you zero beat on the separate rx, the exact freq. of the standard isn't extremely important--it's not what's being measured--it's just providing a reference to get everything set up on. I think these things used to put out enough harmonics so they could be used a number of multiples off their fundamental.
