HW2M

[Mike Bryce]

I do not believe the problem is with the memory battery..

I suspect a switching transistor used to key up the tx..

or it maybe as simple as a problem with the ptt switch.

the reason why the ht cycles on low battery is when the tx is called  
on, the battery is drained to the point the tx drops out. but the  
battery has a few seconds to recover and whoa! the tx goes back on.

I think a quick study of the schematic will show you a switching  
transistor (perhaps a steering diode) that is shorted.

I have an HW2M heath HT in otherwise good condition,
however, if the battery is well charged, when I turn
it on, it locks up in transmit (when the batt is low,
it cycles in and out of transmit).  Any ideas?

I suspect that the internal coin cell is used up.
Also, how do I reset it after rfeplacing the cell?
