Edit: I think I got a little ahead of myself in posting the 'fix' for the problem ... I think it may have been even simpler than I thought in the first place ... I went back to the rig (that was working great...) and it was set to 'USB' instead of 'USB-D(ata)' and when I switched it to USB-D, the frequency display was way off again ... So I am thinking all I had to do in the first place was to change it to USB instead of USB-D to fix the issue ... I will experiment a little more and post back here ... I do apologize for that... End of Edit: Well, I fixed the problem ... All it took was a little research and problem solved ... I came across an article on MorseTutor.com ... and it was dealing with a different problem regarding the FTDX3000 Data Mode audio offset. Evidently, when the data mode is selected, the rig adds 1000 hz offset in the BFO and that was my problem. The solution was to change menu selection 067 to 'OTHERS' and menu selection 070 to '0 hz' ... and it fixed the problem for me working VarAC ... Now I am going to have to watch other modes and see if it affects any of those. Thank you to Gary N3CZ and htperry W4HTP for helping me sort it out. 73, AllaN0KFO
