For frequency, it has no effect, and if the GPS 1pps is being used for audio phase this would just offset the phase as though the transmitter itself were moved by the same number of feet (and/or its feedline increased by that amount)... not audible at all, as audible artifacts only start after a few *miles* of phase error. > Also if these are VHF it could be that the reference frequency > (channel spacing) is 5 kHz, if that is the case a harmonic of a paging > tone might get past the audio pass band filtering 300 - 3000 Hz > typically and is fooling the PLL divider. >
I like this guess,... that the paging tone (or tone remote keying, as I suggested a moment ago) is causing one to come unlocked. Matthew Kaufman
