No, probably not the case. My observations are that the CB vs. 2M popularity is far more agrigate than just geographic. Kurt's 75 to 90 percent is perhaps true with his core of regular trail companions but is waaaay off the mark when speaking of the 4x4 enthusiast community as a whole. I would never venture a guess at the percentage but it would be very close to the opposite of the sacle that Kurt used. He did preface his statement as a guess though.
I think you both may have misunderstood what Kurt was saying. I think I get it.
He didn't say 75 percent of
off-roaders use a 2m.
Obviously that's not correct, most of the off-roaders I see run no 2 way radios at all, and if they run one it's more likely to be a CB or FRS than anything else.
What he said (at least what I understood) was that
of the 4x4 owners who have HAM radios in their trucks, 75 percent of
them are on 2m.
That, I think, is correct. In fact, I think it's probably more like 80-90% of the HAMs who have radios in their rigs have 2m or dual band with 2m capability. The % of HAMs who 4 wheel and who run HF, 6m and the like, is pretty small from what I've seen.
So to sum up: Not 75% of 4x4 drivers, 75% of HAMs who are 4x4 drivers.
Incidentally, I haven't seen any statistics (I'm sure they're out there) but my guess is that a solid majority of the HAM radios sold in the US each year are 2m units.
