The joys of a FT690R and wspr

I have been slowly convincing a FT690R that WSPR is a good idea.
Having a 40Hz droop on your single is embarrassing to say the least. Upgrading the regulators supplying the main PLL is slowly helping and now down to less than 20Hz frequency drift, with receiving stations starting to decode my transmissions. One regulator to go!
