To all owners or those familiar with the BTA-1R series of transmitters:

The "Power Raise/Lower" variable resistor (1R405) is connected to the 
motor unit which turns it when switch #1S202 is operated.  The 
connection between the motor and the rheostat on mine is gone and I 
can't seem to find a legible picture showing exactly how the two 
circular pieces (the one the motor and the one on the resistor) connect 
together.  Mine had a make shift piece of felt held securely by a 
radiator hose clamp at one time, but this too was broken.  Can someone 
take a look at their 1R  and let me know how they are really supposed to 
be connected.  It appears that this may have had some kind of slip type 
clutch arrangement originally, but I could be way off base on that.

Any help and advice will be greatly appreciated.

73,
Rick/K5IZ
