N2GWK Trimode is back to normal after exchanging the XCVR with a backup FT-897D.
The original FT-897D suffered from IF Filter Failure and was deaf as a stump.
Bad connection on the power cable's HF 4 pin power connector to the radio knocked it off the air for awhile. Its been patched, but I will be replacing it with a new cable, connector and power pole connections this summer.
