I gotta agree with Rob. An inverted L aerial wire will hear ALL the noise that is around. Mine sure does. RX antenna will help enormously if there is a place to put one that does not get the noise second hand off the L. Not enough room? A bit complicated, but "repeated" noise off the L can be dealt with.
The worst noises around here heard on my L were all repaired by the power company. The nastiest noise was very hard to find, I actually never "found" it by looking for it. Noise turned out to be from a bad splice in an underground 13 kV cable going from the 13 kV delta overhead out on US 64 to the transformer for my eastern neighbor and next house over. It would come and go with extended cold weather, but never would correlate to sunlight or darkness. I would hear it next to my transformer walking around with my battery K2 and a rubber ducky. It would never locate to up on a pole (only power noise that didn't). Finally the splice hard-arced, exploding the fuse up on the pole for the neighbor's 13 kV feed, and taking those two houses off the grid. The noise went away with the cannon shot noise. Blessed quiet on 160 and 80. I had put up with that for almost four years. In the end, Duke Energy completely reran his AND my buried 13kV lines, and replaced his transformer. 35 years in the ground, 35 year old cable design and materials, and deficient in THEIR opinion. Was really fun to watch them use this super-neat burrowing setup that went right UNDER the woods and the creek (whole other story). Now I can hear the lesser noises on my L from all over Apex and Cary :>) Need RX antenna for sure. That way I don't have to listen to the Cary, NC noise (NE) at the same time as the generally closer and louder Apex, NC noise (S, SE). 73, Guy K2AV On Tue, Jul 23, 2019 at 9:37 AM Rob Atkinson <[email protected]> wrote: > > Over past few months, I have picked up an S5-S7 noise signature on my TB > inv > > L antenna with K2AV FCP system. > > I would not use an inverted L for receiving.
