[1000mp] Frequency Accuracy/Stability

[Jeff Goldman]

I would like to increase the overall accuracy and stability (time and 
temperature) of my FT-1000MP.   Any recommendations on the possibility 
of adding a small oven on the main oscillator?

Or what about some sort of scheme that would allow frequency control 
from an external source (such as the good time base in an ovenized 
counter, etc)?  The main problem I see here is that the MP's frequency 
is 10.48576----not exactly easy to generate from a typical standard 
frequency.

I know that the TCXO-4 and -6 are available, but even -6 is at best 0.5 
PPM from 0-50 C, and an oven will be better than that and almost 
totally eliminate the temperature drift if the oven is powered on 24/7.

Any thought or comments would be appreciated.
