Well, according to the FCC's list at 
<http://www.dtv.gov/FULL_POWER_STATIONS_LIST.xls> there will be two 
"full-power"  DTV stations (WISE-TV in Ft. Wayne, IN and KSNB-TV in 
Lincoln, NE) remaining on Channel 4 after June 12.

So that's two stations coincident with the IARU R1 4m band (70.0-70.5 
MHz). Perhaps the FCC isn't posting accurate and current information on 
its consumer website, but ...

OTOH, it is quite true that many (205) low-power, Class A, and TV 
translator stations will remain on Channel 4 after June 12. Each of 
those would need to be adequately protected; and it would not be as 
simple as specifying a couple of geographic restrictions for amateur 
operation.

An even bigger hurdle that any petition would have to overcome is 
addressing the concern for interference from amateur operation on 4m to 
TV interface devices such as VCRs, DVDs, DVRs, satellite and cable boxes 
that have their outputs on Channel 4.

Preventing direct pickup interference to poorly-shielded consumer 
devices was the FCC's rationale for excluding Channels 3 & 4 from use by 
unlicensed, low power TV band devices in the television "white spaces" 
docket.

Trans-Atlantic 6m/4m crossband contacts have been completed. Perhaps 
some very limited operations under an experimental license such as the 
ongoing 500 kHz tests might be possible. But, I really can't see a 
secondary amateur radio allocation at 4m in the cards, at least not 
anytime soon.
