50.62 rang a bell with me, and I googled it.  It seems that Bob Bruninga
wrote a paper some time ago about the issue, and 50.62 is indeed the
frequency used in his area.  See http://aprs.org/6m-aprs.html and
http://www.tapr.org/pipermail/aprssig/2010-August/033903.html

Anybody using six for APRS?  What radios and antennas do you use?

I believe it is 50.62. 6 meter seems ideal for a longer range fixed station
messaging backbone. If we got some smarter path routing involved we could
get some real range out of the system without being reliant on the internet.

If anyone is interested in setting something up in southern california I
could setup a station(igate, digipeater whatevers needed) in culver city.
