Over the years I have repaired a few older JR transmitters with either non functioning or even worse still intermittent power switches.
As well as being a very small switch JR have in their infinite wisdom used the switch to separate two positive supplies.. I believe one pole of the switch feeds the RF board and the other the logic believe this is so that the logic can be powered from the receive battery without powering the RF when using the DSC facility.
I have an old but good x-378 transmitter that, whilst showing no signs of a switch problem I would still like the security of using both poles of the switch. Since I never use and never will use DSC is there any other reason to stop me linking both poles of the switch
