[time-nuts] Lucent RFTG-u REF0-REF1 cable

[Jerry Hancock]

It turns out I don't have an M12+ in the TAPR GPS.  I always knew I had an older model.  I 
checked the numbers and pictures and it it just what I need, an Oncore UT+.  So the first 
thing I need to do is get my REF1 standalone and then add this GPS to the REF0 and 
problem solved.  I also have to get the 10Mhz out of the REF1 but that looks easy.

Thanks for all the pointers.

Jerry
