Equipment / Re: LOG Not Performing Well
« on: September 08, 2021, 0220 UTC »
Funny you should ask 
I have spent the past month or so working on a LOG for my LF/HF RX. Mine ended up 300 feet long, 75' per side square. I made my own matching transformer (?) , a simple 5:2 wound with magnet wire using a binocular core torrid as my feedlines are 75 ohm. It is incredibly quiet, but....I need to run a lot a gain sometimes (MOST times), depending on conditions. All I have to compare it to is (was) a 120' end feed longwire with a 9:1 balun, until a recent wind took it down.
The Longwire seemed to pick up more signals, but there was a lot of noise as well. The LOG signal levels are much lower, but I can really crank the gain with the low background noise. As with most antennas I ever bought, built and/or used...Conditions are everything. During the day on MW and HF it is pretty good, but after sunset it reallys seems to come alive. LF is all but dead during the day, but at night it's a totally different story.
My radios are a SDR and a Kenwood R1000, so nothing incredible there, but I do use a homemade pre-selector and preamp and it seems to help, again...depending on conditions
