Longstandiong WUNR Towers Down (No Scott Photos?)

[Dan.Strassberg]

WUNR's 20-kW signal will be lower than its old 5-kW signal beginning
at an azimuth of 138 degrees true (that is, to the southeast), and
moving clockwise, all the way around to 6 degrees true (just a skosh
east of due north). The biggest gain will be at 83 degrees (just north
of due east), where the signal will be equivalent to a power increase
of almost 6.5 times. Remember that, because of the lower efficiency of
the shorter towers, the effective power increase is not 4 times but
only about 2.8 times, which maybe makes the 6.5 times increase in
effective power to the east seem a little more impressive. The big
beneficiaries will be Boston, Brookline, and communities on the near
North Shore, but you are right; the signal will improve somewhat in
Cambridge, Somerville, Charlestown, et al. Also Quincy and Braintree.

With regard to WUNR, I'm aware of the limitations to the
north-northwest,
at least in theory, and I'd expect signal diminution heading up route
3;
but WUNR must be getting SOME bang for the buck, and thus there may be
a
little boost east of due north, and therefore a person heading north
on route 93 after the switchover  should expect a little better
signal,
with the bulk of signal improvement hitting Boston itself, Somerville,
Medford, Everett, etc.  As for WSMN in its present configuration, I
was in Nashua recently and it covers the City pretty well during the
day;
how it does just after sunrise and just before sunset, the nemesis of
stations in the 15's, I can't tell.
