I'll let Jon respond on his own situation but I think his -9700 is
externally referenced-- as is my FT-736.  And between Jon and I, we
are always exactly on the same frequency.

I am transmitting with offset 1480 Hz (per the WSJT setting) and Jon
reports all of my spots on 144.49080 +/- 1 Hz and 432.301480 +/- 1 Hz.

Similarly, I spot him at 144.490500 +/- 2 Hz.  I have not seen Jon on
432 yet today but I conclude his TX offset is 1500 Hz, the default.

Yesterday when we were playing on 1296, we were both on 1296.501500
exactly for each of us, on each spot-- no drift.

You can look in the WSPRNet database here,

https://www.wsprnet.org/drupal/wsprnet/spots

and set up the query to show what others are seeing from you and vise-versa
as a good way to check this sort of thing.   This of course assumes those
spotting are uploading their spots.
