More on WWV, Frequency Alignment, and Yaesu Radio Data Modes

Last month I posted a tip on how to exorcise the built-in – and incomprehensibly documented – data mode offsets in some of the newer Yaesu radios.  This past week I've spent some time helping a friend sort out the same problem on his FT-991A.  A couple of hours into this process, we likely still have at least an hour more to go.

Now I see that other people are having the same problems, and documenting their solutions on the web.  Generally this involves using WWV's signal as a set of reference frequencies while plowing through menus and manuals, zeroing out unwanted pre-set offsets one by one, and muttering small curses all the while.

If you've got the patience to fix these factory-standard defects, now is a good time to pick up otherwise fine radios at fire sale prices.
