A question for you "Tekkies". Today, for the first time I can recall, I widened the P3 span to the full 200K bandwidth display. While listening on aux receive antennas for 160 meters, I could see a half moon shaped noise floor that started gradually rising from S0 at about 1.775Mhz, peaking around S3 at about 1.830 and slowly declining again until back to S0 level at around 1.875Mhz (A nice even arc of noise).
Would this be noise from my series fed 115ft top loaded 160/80M xmit tower that I am seeing? I have a vacuum relay that disconnects the feed /radials from the tower when receiving and I didnt see much if any difference when switching the relay in and out manually. curious now as to what I am seeing.
