Hint for Finding Nearby Transmitters
There's been discussion about neighborhood transmitters
interfering with TV's and stereo equipment. Here's a tip
for finding a radio transmitter operating close by:
Connect a frequency counter1 to an outside antenna!
One of my scanners was being overloaded by a nearby
transmitter. I didn't know anything about the type or loca-
tion of this transmitter, but was determined to find out.
By connecting my 520 MHz frequency counter to an outdoor 2
meter antenna, I was able to determine the station's fre-
quency. The strong signals were coming from another radio
amateur that was operating his own 147 MHz repeater in an
apartment about 500 feet away from me!
His signal was so strong, that my counter indicated a stable
frequency reading with a 19" wire antenna plugged directly
into the counter!
__________
1. Insensitive frequency counters may require the use of a
broadband preamplifier between the counter input and the
antenna.
