George -
'Exercise' the slide switch on the left side of the radio, and make sure
it is left in the 'TCVR' position. This is the most likely cause of
what you are seeing.
Other possible causes are relay contacts, 'fuse' bulb in the receiver
antenna circuit, associated wiring, or last and much less likely, a
fried input coil on T9.
Looks like the clock back-up battery in your computer has died too! :-)

Just got home from Dayton with a TR4CW/rit. Hooked it up and find that
the transmitter will put out 150w on cw. All controls seem to act
correctly. SO I think I am OK on the transmitter side. The receiver
needs some work. I can hear signals but the s meter does not react.
The calibrator moves the s meter to S9. Keying my K3 kicks the s
meter to 20 over. Signals which are S9 on my K3 are just readable on
the TR4CW w/o any s meter action. I plan to DeOx first and then
proceed from the antenna relay looking for trouble. But before I go
through the usual suspects, does anyone know if there is a frequent
"violator" typically causing these symptoms? Although I have
experience troubleshooting the Drake C line, this is the first time I
have dealt with a Drake transceiver. All help appreciated.
