[TenTec] Model 544 Frequency Hopping

Hi Ten Tec Users,

I recently acquired a model 544 Ten Tec Triton IV--and for about a week it
has been working perfectly. Then this evening I noticed that the frequency
display was jumping all over the place--it was not just a display problem
but the frequency was moving too! The worst case is on 20 M where the VFO
feeds the mixers directly. The frequency jump can be as much a 1 Khz. It is
random too! Once it moves it continues to do so. Sort of like the one of the
first VFO's I built.

I suspect a voltage regulation problem. The regulator board has a 723
regulator that is set for about 8.0 volts and this powers the VFO--but there
is no adjust ment--( to see if raising the voltage would cure the problem).
Any one out there seen this problem before?

I will call TT in the morning but thought some one here on the reflector
"has been there, done that"

Thanks

Pete W6JFR
