[1000mp] Sub VFO on FT-1000MP

[Michel van der Walle]

Hi from Down Under.
My FT-1000MP has develloped a fault in the Sub VFO.
When rotating the tuning knob the frequency does not change accept the last digit on the display.
However this digit changes randomly, sometimes going up in frequency when tuning down and visa versa.
The change is not smooth but jitters.
There is no jitter in the display when not tuning.
Is there anybody on this reflector that has come accross this problem and perhaps knows what it is and how to fix it.
Or perhaps a technical guru that knows this radio better then I do that can help.
My other option is to send the radio for repair to Sydney which is a 1000 Miles from my QTH and I really don't want to do that.
Damage to the radio in transit would be a real possibility.
Looking forward to advice
Warmest Regards
