Hi All,I understand this RFTG-m-RB and RFTG-m-XO already discuss many-many time
in the past but I need to ask for something that I don't clear enough..1. my
GPS antenna position can give 6 to 8 satellite at once times with a good signal
is that enough ?2. I believe the GPSDO and Rubidium are "comparable" in
stability so I do not fully understand why I need Rubidium GPSDO ?3. I
understand Rubidium has "lifetime" are this lifetime count from when its use or
from its manufacture ?4. How good the psu I need ? I see inside of my RFTG-m-RB
and RFTG-m-XO they use an DC to DC converter are 24v switch PSU is good enough
or must I linear PSU ?5. How to sure my RFTG-m-RB and RFTG-m-XO combo are in
spec ? 6. The best and the only calibration place I know here in Indonesia are
Indonesia NMI with a PHM the cost for calibration is "not much" but the time is
long (6 month) with 10-e10 maybe 10-e11 are this kind of calibration (without
adjustment) is to much ?
Sorry for my Java English and for so many basic question.
Thank You
