I have heard 0ne person in 2 1/2 years on 6m ,of course I don't monitor it 24/7, I think monitoring deep space for ET to call would be more interesting. Have heard some guys on a jeep forum talking about them using 6m instead of 2m for their off road groups, we tried it here but couldn't even be heard by a base 20 miles away, and iffy mobile to mobile over a few miles, maybe we weren't holding our mouths right or something. Seemed like it should work, heck back in 70's we used 37.180. ,42.900, 45.200 for SO and Fire freqs, worked great mobile /mobile,and base to mobile. Of course about 1977 we went VHF . I have a bunch of radio friends down here, some hams for years, only one has had luck on 6m, there is a net in Corpus Christi, rumor has it that maybe 2 or 3 can talk across town, but friends that live across the bay have never been able to make contact, most of us took down antennas to free up space for better 2m antennas, trying to maximize for simplex.
