according to the ARRL six meter band plan:
ARRL 6 Meter Wavelength Band Plan:
 50.0-54.0 MHz


50.000-50.100 CW and beacons

a.. 50.060-50.080 Automatically controlled beacons
50.100-50.600 SSB
a.. 50.125 SSB DX calling frequency
a.. 50.200 SSB domestic calling frequency (Note: Suggest QSY up for local & 
down for long-distance QSOs)
50.600-51.000 Experimental and special modes
a.. 50.700 RTTY calling frequency
50.800-50.980 Radio Control (R/C) channels, 10 channels spaced 20 kHz apart 
(new)
51.000-51.100 Pacific DX window
51.000-52.000 Newly authorized FM repeater allocation
51.100-52.000 FM simplex
52.000-52.050 Pacific DX window
52.000-53.000 FM repeater and simplex
53.000-54.000 Present radio control (R/C) channels, 10 channels spaced 100 
kHz apart


a.. Supplementary info says that 50.8 to 51.00 is now commonly used for RC 
control, and 53.0 to 54.00 is used for repeater operations... I believe that 
six meters has a 20KHZ band width limitation for transmitters, so I would 
presume that repeaters would be spaced around 30KHZ apart typically.
a.. That said, there seems to be no universal spectrum allocation as there 
is on 2 meters and 70 CM as far as band width and where repeaters must 
transmit.
a.. I would say a general 1MHZ scan between 53 and 54 megs would be a better 
way than trying to program in every possible repeater frequency...you would 
probably have to program a channel every 5KHZ to cover them all between 53 
and 54.
a.. that said, my own observation says that most repeaters are located from 
53.4 to 53.7 or so.
