Overall it was useful to me in locating a few sources of RFI, you point it in the general direction of a noise source, and wave it around until you get a peak in the meter. Once you have that, you walk towards the source, waving the antenna around, following the peaks.
The device is reasonably well constructed, MFJ quality control seems to be good, as the unit I got has no defects in it. It came boxed nicely, and was simple to construct. There were a few items to note… Continue reading
Radio noise from sources associated with hardware on distribution power lines was the
primary kind of radio noise affecting the signal-reception capability of radio receiving sites for many years. Only a very few remote sites that did not obtain power from overhead distribution lines and did not have distribution lines within line of sight of the uppermost part of antennas were free from the noise problems described in this document.

The ARRL is currently sponsoring a program for exchanging QSL information in a secure way for use in obtaining various awards from the ARRL. This program is called “Logbook of the World”. The ARRL was late to the blocks in implementation, eQSL.cc was first, however the ARRL decided to implement a tighter security model than eQSL. Hence eQSL ended up being on line earlier than LOTW.
