Dean, the radio was cutting out. Initially, other pilots would mention
scratchy and broken transmissions, later the green "Receive" light on my
radio would illuminate but no audio would be forthcoming, finally, the radio
would not function. I'd also see a large voltage drop when keying the
transmitter - sometimes over 1 volt. Switching to a fresh battery would not
solve the problem. I expect switching batteries under load caused pitting
and/or carboning of the switch, making it a high resistance junction.

After two flights with the new master
switch installed it would appear that the problem is solved.

Dan, Just for interest what were the symptoms you were experiencing?
