TS-590SG and WSJTX errors


KA5VZG
 



Two antennas into an LDG AT-200Pro II autotuner, connected to TS-590SG. Using WSJT-X v 2.5 and JTAlert 2.50.6 .
Also using virtual COM port and following Kenwood web instructions for USB connection.

WSJT-X is set up per Kenwood "Setting up the TS-590S/SG for FT8 operations.

Using ant #1 (A-3) everything works fine.

Using ant #2 (Carolina windom 80) get these two errors:

OM,

errors on both audio and CAT control when both are carried by the same USB connection, and that only happen with one aerial, are highly likely to be due to RFI disrupting USB communications. There have been many threads on this list discussing this issue with many potential solutions. Bottom line is you need to reduce the level of RF currents flowing on the outside of cables within your shack.

Sounds like RFI.  Reduce your power to zero and I'll bet the problem goes away.

1st thing to do is describe your grounding system for your shack.  Too many people have poor ground setups.

Yes, and per Jim's K9YC document. grounding does NOT help RFI issues.   OCFD antennas {i.e. Carolina Windom} are noted to have high levels of common-mode current.  Grounding does not correct or cure common mode current issues.   Don't believe "old wives tails" or better yet "old ham lore" on grounding.  Most were incorrect to start with and the telling get worse, not better.   

Jim, K9YC, has great information on common mode current issues and how to address them.  Thus grounding I don't recall as being a solution.  Now, bonding of all equipment cases is the first start in solution to the issue.   Use of proper RF chokes is next.
