[time-nuts] 20Hz p-p / 24 hours with a Mini-T

Hi group!

I need some opinions, counsel, help, whatever you can send my way:

I need to maintain the Mini-T within 20 Hz p-p in a 24 h period. I use 
T=450 and all is well until the thing starts to lose satellites one by 
one and goes into holdover and after a while, the VCO voltage jumps to 
the start value and with it the frequency (up to -150Hz).

The antenna is not in a good place and it can't be moved, but if I 
restart the Mini-T, all satellites that were grayed out come alive and 
strong. Any clues?

Thanks,

Miguel
