[1000mp] Why??

[Al Toothaker]

Yaesu is playing (a little) specsmanship when talking about PPMs for
stability at a single temperature and on the next line in the specs, talks
about a range of temperature operation.  If the stability does not hold over
a range, what other specs also vary with temp?  For me, I really don't care
since the rig makes the QSOs I want.

Page 1-2 of the FT-1000MP service manual:

TCXO-4 <+- 2.0 PPM  (0 - +50 C)
TCXO-6 <+- 0.5 PPM  (0 - +50 C)

I think where the confusion lies is the way Yaesu states the stability
in your MPMKv user & service manual.  0.5 PPM (parts per million) after
1 min at 25 C and 0.25 PPM after 1 min at 25 C with TCXO-6.
