Hi Alberto, All,
 
I think you mean the HP-10811 XO instead of the HP-80111?
 
I saw the HP-10811 on Ebay for about US$ 200 (after I heard about it in the
conversations of Graham on the recent Teamspeak)
I have to read some more I 'm afraid after all the good info in all the
posts here. (Thank you all!)
 
I don't know what one would have to pay for the Trimble Resolution-T or the
iLotus M12M pointed to by Graham but if I aim for an "HPSDR
average-per-card" budget of say US$ 150 to US$ 250 and both being not
surplus market items and priced as such I think the budget will be too
small........!   :-(   
 
I have to read a lot more I 'm afraid after all the good info in the posts
here. 
 
Thank you all!
 
 
73,
 
Henry.

Thinking of getting into precise frequency control for HPSDR, are there

other surplus GPS's currently available, better suited for frequency control

in the opinion of this forum, besides the Motorola Oncore UT+ mentioned by

Graham?

  


This maybe, the Trimble Resolution-T, with 15ns jitter (one sigma) on the
1pps pulse.
It is not surplus, it is currently on production, AFAIK. I have ordered one
to discipline
the double-oven HP-80111  I was  so lucky to find some time ago.
