[time-nuts] New pics of RFTG-m-Rb, and some comparison details

[Jason Rabel]

The RFG-XO doesn't have a GPS unit in it. It has a 10 MHz in, and of course
the 15 MHz out. It also only has three DB9 connection, the 24V, interface,
and alarm.... It is missing the RS-485/1PPS connection.

Similar the RFG-RB doesn't have the RS-485/1PPS connection.
