Today I was using JT65 and saw a group of call signs that appear to be unknown or nonexistent.  Here they are does anyone recognize them.

They are invalid calls, based upon bad decodes in the software. There have been several threads about this in the past.   I don't think I've ever seen these in WJST-X, but they were quite common in JT65-HF.

Thanks for the info.  I suspected bad decodes but I never had them in JT65-HF so I didn't recognize the problem.  Now I guess I must figure out why I am getting bad decodes.
