Hi Rick,
I can relate to that!! I have used one of those MFJ devices.
As a noise receiver it worked very well, but I found that the
telescoping dipole is almost useless for pin pointing noise
in areas where there are many service connections. In
other words the noise can seem to come from a number of
sources (an it often does). another thing about the MFJ...
wear headphones because the weaker noise sources will
not deflect the meter.
I would suggest building a 3-el beam, such as the one described
in QST...think the article was named "A noise sniffer that works".
I tried one of those Radio Shack aircraft band radios and found that the
"hiss" from the radio was just unbearable...no hiss from the
MFJ unit.
I made two modifications to my MFJ unit:
--Installed an external antenna jack and a switch to select either
the dipole or a external antenna.
--Installed a red LED behind the meter for easy nighttime viewing
of the meter. Another switch controls the LED.
73,
Charlie, N0TT
