WITS/Red Sox

I am surprised that WWZN's NIF is that low! And if CJRS were still on the
air (and assuming that, when it was, it ran within its licensed paramters),
it would be a significant contributor to the CO-channel component of WWZN's
NIF (much greater than WNLC at night--WMEX et al's main problem with WNLC
occurred in the daytime). Since CJRS (like nearly all dark Canadian AMs)
remains notified to the US, its contribution (or its contribution assuming
it ran within its licensed parameters) must remain in WWZN's NIF
calculation. It would be interesting to know whether JT ran the calculation
with or without CJRS.

Anyhow, if 7.4 mV/m is the operative number for WWZN, the outlook for WKOX
doesn't appear especially bright. According to JT, WKOX's NIF is 13.5. The
combination of a less efficient antenna system than 1510 and a significantly
higher NIF really reinforces the idea that WKOX's 50 kW signal will be no
great shakes (especially at night). Of course, WKOX's frequency is 20% lower
and SawMill Brook Parkway is probably superior to Waverley Oaks Rd in terms
of soil conductivity. And one can argue that WKOX's patterns are more
favorable than WWZN's. But whereas there are some who are in love with the
SawMill Brook Parkway site, based on my lousy reception of WUNR all of these
years, I can't understand why.
