Dale and others, Thanks for the suggestions thus far. This morning I took off the top and bottom covers and don't see any loose connections. Does the back circuit board, on top side of the radio connect directly to the RF connectors or are there other jumpers between?
Connected -40dBm tracking signal spanning 20M band using Rohde & Schwarz generator into each of the 3 antenna input ports. Result: when each antenna port is selected I see and hear the signal but it is 80dB down. So I connected the tracking signal directly into the RX1 IN port and selected use RX1 Out to RX1 In loop on the antenna selection form. Result positive: see and hear the -40dBm signal, connected antenna directly to RX1 In port, receiver works this way. Sure wish I had a schematic of the radio, getting close. TX/RX circuit hardware stuck in TX?

When we run them here, they will fail. So, the fact that the other tests all ran fine (except for the two failures -- more about that in a minute) indicates that your radio receiver is actually working fine. I think we're getting closer to the I/O board on the back panel. You may be exactly right in your speculation that a cable has become disconnected somehow. Regarding the two tests that failed, I'd suggest that you try just those two tests again. I usually end up with one or two tests that fail, yet when I try them again, they work fine. Click the "Clear All" button in the 'Bands' section beneath all the checkboxes. Then, check both the 17M and 160M checkboxes and run the tests again (they'll go a lot faster this time because you're only testing two bands). My bet is that they'll pass this time around.
