	My RFTG-m-XO arrived.

	Seems like they use a version of the UT+ timing receiver
R5122U1155, which is an 8 channel version of the Motorola Oncore design
optimized for timing.    This 2002 or so version seems to have been 
retrofitted to a 1996/97 base design.

	Apparently have an external antenna power supply on the mezzanine
board - presumably to allow the 80C188 to read antenna current (or maybe
it supplies 12 volts instead of 5).
