I appreciate your comments. The problem I was having was - while split and fake it operated just as you described, the actual desired audio frequency was not correct. I verified this by monitoring my actual transmitted signal on a second radio running WSJT-X. The ACTUAL transmitted audio had a constant offset. NU4E also experienced this problem at his station. The offset caused severe problems when operating because the frequency (say 1000 hz) I thought was being sent was not sent. Instead 1500 Hz was actually being sent. (I don't remember the actual offset - sorry). I verified this on the second independent radio and WSJT-X setup. I was making very few QSOs when this happened, even with 1 KW output. Once I stopped using split or fake it, I verified the ACTUAL transmitted signal on the independent WSJT-X and the problem was gone. I started making QSOs at good rates. I run SO2R FT8 & FT4 so verifying this problem was easy. My second SO2R radio setup never experienced this problem.
