Hi Peter

I 'think' VR03 may be the mic gain on the front panel. I think the pot VR01 is the deviation pot on the TX board. I have tried this, but as it is deviation, only has any effect on FM.

Thanks for the info. I think I'll pull out the diagrams and have another look.

I was hoping fir a simple fix, but I think it may be a case of changing components to alter the gain of the mic amp. I was reluctant to do that for the sake of a headset!
