I bet 6 meters is going to be a whole lot quieter, once the analog stations go away. I think anyone who parses through the channel allocations for DTV will find that there are going to be only a small handful of DTV's operating on channels 2 or 3. This is because broadcasters found that low band VHF channels (2-6) are not very friendly to DTV signals, due to increased co-channel interference and increased levels of noise from powerlines and lightning. Most stations (like channel 2 in Chicago, for example) that were given DTV channels in this range are fleeing to higher frequencies, for the final transition.
Incidently, the next big push for broadcasters will be "maximization." This will result in a bunch of applications for higher DTV power levels, once the analog stations in the spectrum clear out.
