Will it hurt to leave my mt1000 on the charger with the radio on during night-time hours? Will it stay fully charged? Its the only radio I have that has tone squelch that I can use in the house so that I don't wake up unless my departments tone is set off....there are 11 fire departments that use the same vhf freq and each has their own two tone alert.

I know its not recommended, but sometimes if I am using my mobile somewhere that its not in the house, I keep my GP300 on while in the charger, but dont try to Tx in the charger!

Monster is right. They say not to do it, but assuming you're talking about the rapid charger, there will be no problem. The rapid charger knows when to reduce the charge rate to a bare trickle, etc. I've had a P200 (just about the same radio as the MT1000) in a rapid charger for a couple of years, monitoring. It works fine when I pull it out, though it's not the best battery in the world. Never a problem though. Probably a 6 hr charge instead of 8-10, but so what?!

If you have the standard charger - the little base with the wall wart - that will cook your battery if you leave a charged battery in it. So the above is based on you having the rapid charger.

Monster is also correct - don't put a speaker mic on that radio and transmit while it's in the charger. You'll sound horrible and likely fry the charger. Not good. To transmit if needed, pull the radio.

We used rapid chargers on MT1000
for 9 years without one problem to
rx only when charging.

Leaving the radio on with a slow charger will prevent charging. Leaving the radio on with a fast charger will confuse the charger and may lead to cooking the battery. A better bet is to acquire a second battery for "overnight" use, and recharge it while you're working during the day. Or get a Motorola battery eliminator and hook it up to a 12V power supply.
