Joe,
I thought all the analog TV channels were de-allocated when we went all
digital.

In order to be of use a US allocation should match that of the rest
of the world - approximately 70.0 - 70.5 MHz. Unfortunately, that
is right in the middle of US TV Channel 4 and there are quite a few
authorizations on Channel 4. See: http://www.w9wi.com/channels/4.html
Protecting the grade B contour of each authorized channel 4 station
would make any 4 M allocation off limits in much of the US.

I would like to see 4M released for ham use, not necessarily for
repeaters, but rather for weak signal use. There are many times when the
MUF goes above 50 MHz, but doesn’t reach 2M. 70 MHz would be very useful
for sporadic E. Meteor scatter would still be good there, not as good as
50 MHz, but much better than 144 MHz. EME, with WSJT, should be
significantly easier than 50 MHz. With a limited number of 144MHz and up
ops here, 70 MHz would really help the VHF/UHF contest scores in this
area. The whole state of NM has a 50W limitation on 432MHz, so we are
limited as to contacts on that band.
Amateur use of 70 MHz should be able to coexist on a sharing basis with
current users, with perhaps some limitations near critical users, if there
are any. It is an issue that is pretty far down the priority list for the
FCC or the ARRL though, so it will be a while. - DUffey KK6MC
