Re: [IRCA] New MW QSL (KCFM)
I always wondered if anyone was using a Kintronics Kinstar system. Do they
get out as well as before? After putting in the Kinstar they had to decrease
day power from 1 KW to 900 watts and nighttime power from 68 watts to 37
watts. Why? Was the ground system at their old site really messed up and
this one is so much better that they'd cover more area if they ran the same
amount of power? They didn't move very far; a little over 2 kilometers.
There's a whole lot of top loading going on here. The system does eventually
add up to a quarter wavelength (90 degrees electrical height) but 61.2
degrees of that is top loading. The dealbreaker for me is that even though
the towers are a lot shorter there have to be four of them instead of one
and they still have to have a traditional quarter wavelength ground system;
120 quarter wavelength (60 meters) copper wires spaced three degrees apart
and 60 meters long. Their new site still occupies as much land as the old
one.
I swiped some of this from the Engineering Statement:

Subject: [IRCA] New MW QSL (KCFM)
After having such a long dry spell, since May, I received MW QSL #3006
in todays mail.
1250 KCFM OR, Florence, received very friendly letter in 6 days
for CD report.
from Jon Thompson-GM/Owner. Address: 4480 Highway 101, PO Box 20000,
Florence OR 97439.
The station moved to a new tower setup and dropped to 900 watts. They
are using a Kinstar system of 4 poles that are 70 feet tall, instead of
their 200 foot tower. "Kintronics recently got FCC approval on this
tower arrangement, but ours was the first commercial tower ever
constructed and tested."
