In a word 'No'

This phenomenon normally occurs with a transceiver which has had a PLL synthesizer alignment without letting the radio warm-up first.

As per the alignment procedure, put the clarifier control(s) in the center detent, then re-adjust offsets.

You'll need a stand alone frequency counter with 25mV sensitivity, an oscilloscope, ceramic trimmer tools, & a service manual.

Failing that, have it done for you by someone with the appropriate equipment & experience.

PS Where in Yorkshire are you? West, East, etc???
