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).
