 OK, I see now about Pin 9 and would think it's bad practice. The same batteries are in the unit though as when I began all this and nothing seems to have been harmed. Must be a few hours of tests so far. Being a variable resistor i'd think it would still place any load onto the resistor and hence battery life not component life would be the issue. I could very well be wrong...and I don't mind being told that :)

Solved the 99/1 duty cycle problem. I read somewhere about putting a diode in parallel with R2 on the 555 (Pins 6+7). Doing so fixed the issue, so that now there is a brief blip to reset and rescanning takes place again. Simple enough fix.

We'll have to trade schematics !
