[Elecraft] OT 4M

[Joe Subich, W4TV]

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.

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.
