I used to use my KPC3+ with my FT-857D quite a bit.? I also use to use a Signal Link for digital modes.? I have not touched the radio in about a month.
I recently tried to check in via packet for local net.? Connected the KPC3+, tuned to the frequency, changed the mode to 'PKT'.? I could see other nodes on the frequency via the S meter, but the TNC was not responding.? I tried to connect manually and the TNC would not connect to the radio.? I reset both the TNC and the FT-857D to factory defaults and tried again.? Nada.
I broke out the Signal Link.? Connected the HF vertical, tuned to 7.074 USB and checked to ensure menu 38 was set to 'USER-U'.? Again, no joy.? I cannot decode or encode FT8, JS8, or PSK-31 no matter the menu 38 selection. Somehow the 6-pin DIN interface has gone dead.??
?
Just to ensure that the KPC3+ or signal link are good, I connected them to my IC-7100 and everything works flawlessly.
Has anyone seen the 6-Pin DIN malfunction or die?? I am at a loss.? Usually the FT-857D just works.? It has never failed me before and thus I have never had to troubleshoot an issue.
Thanks,
Chuck, K6CES
