Repack

[Jim Hall]

I noticed WBZ-TV is running information about the channel repack due to
happen on 2 August, advising people to rescan as of that date. In the
repack, WBZ-TV will move from RF 30 to RF 20. At the same time, WCVB will
move from RF 20 to RF 33. My question is, why doesn't WCVB stay where it is
on RF 20, and WBZ-TV just move from RF 30 to RF 33? I'm sure there must be a
reason, but what is it?
