TM-455E Is it dead, or just unconscious? ;-)
 

Hi,

I've just purchased a second-hand TM-455E 70cms multimode to use as an
uplink transciever for AO-40. It initially powered up okay, and receive
worked well. However transmit was "interesting". When the mike-key was
released the set would continue to transmit for up to around two
seconds. The period of time was not constant, and would depend upon the
length of time the mike was keyed. This happened on both FM and USB. I
couldn't find any reason for this in the manual, so I decided to do a
full reset by holding down the MR and Power keys. The set switched off
and I've not been able to power it on since. The fuse hasn't blown,
checked that. Tried wobbling the power cable and the cable between the
main unit and front panel.

What HAVE I done???
