Hello,
I am looking for a little help.
I have an Kenwood TMG707A which I have reset the chip
diodes / resistors so that it is the European (TMG707E)
version. All is well with the frequency coverage / bandplans
etc.
But the 1750Hz tone is so low in volume that it can not be used
to access the repeaters that still have not got CTCSS on them.
CTCSS tones work OK.
Has any one got a service manual / circuit diagram or knows how
to adjust the 1750hz tone level. Nothing else needs adjusting
only the volume of the 1750hz tone - the deviation checks out OK
and the rig sounds great.

Thanks in advance Martin
