Just joined the list and I am looking for some advise.  I just bought
a Z3801A/58503A from an outfit in China to use as a frequency and time
standard for Ham radio.  I am undergoing a learning curve as I try to
get my mind around the technology.  The package came with an antenna
and some software and a power supply.  I have since discovered the
Z38XX software.  It appears to be a Z3801A in a an HP case that is
simuliar to an HP 58503.  It makes a nice looking package.  My biggest
concern is that the power supply that came with the package is 24
volts and the back of the box indicates that it requires a 36 to 60
volt power supply.  The unit powers up and locks on the satellites and
talks to my computer just fine.  I am concerned if I need to use a 45
to 55 volt supply or just go with what I have.  I have run the Z38XX
software but I dont really understand yet what the charts are telling
me, outside of the sat signal strength and pattern.

Thanks for you help.
