Randy,
The External Reference will lock no matter which TCXO is used. Yes,
both the standard +/- 5ppm and +/-1ppm TCXOs are true TCXOs.
The difference between the two will be the desired short term
temperature stability when the External Reference is not active.
I think the rest of your list is accurate.
Your choice of the external reference type is quite apart from this
response. I have the Thunderbolt and am quite happy with it.

Good evening all. After seeing all the posts on GPSDO's I need a bit of
advice and clarification.
I have a K3 with new Synth boards (main and sub). I am thinking I need
equipment for freq stabilization/reference. I am looking at all of the
following and am not sure if I actually need all or any, and if I should,
do I need all of the following:
Will be using - *K144XV
<http://www.elecraft.com/manual/K144XV%20Data%20Sheet%20rev%204sm.pdf>
Internal
2 M 10w Option*
*KTCXO3-1 TCXO*
*K3EXREF* *Ext. Frequency Reference Input*
*K144RFLK K144XV Reference Lock Board *
Leo Bodnar GPS Frequency Reference (or something similar)
Any guidance will be greatly appreciated!
