None that I specifically noticed. I get s2.5 to s4 noise floor though and im sure at least some of that is from the house.
Keep in mind the roof top radials act as a sort of shielding from RFI for the active vertical, so they are particularly good for rooftops.
The first time i installed this a decade ago though when id transmit my neighboors backyard light would turn on... which kinda sucked considering iw as running an APRS beacon 10 minutes apart :)
@freemo@kilroy_was_here I was thinking the radials might have that effect. Might give a vertical a try one of these days up there. I’ve found 40m CW or FT8 to be particularly triggering. Last night it rang my doorbell system. 😬
Its not usually the mode but the frequency + power.. i am willing to bet if you switched to FM on the same freq and transmitted youd get your doorbell going off too.
Yea its just cause they put more power into the band.. SSB if you arent talking but are pushig the PTT nothing will come out the antenna... it only puts as much power in aws the volume it hears... If you make a very loud whistle into SSB it would be almost the same as CW (except not quite as clean a tone obviously)
This is one of the reasons my elmer always told me to tune up in CW or AM mode (FM wasn't common on radios back in his day). The more power going through the antenna path the better you can dip your SWR meter.
Dear Dr. Freemo: The antenna looks pretty good on the Standing Wave Ratio (SWR), I have encountered the subtle changes in SWR readings when an antenna flexes in high winds. Have you ever encountered subtle changes in SWR readings during high winds?

@freepeoplesfreepress I have not seen changes in SWR during high winds when measuring it under these conditions or from the radio. I can pick it up, however, when i use my higher end equipment. Its very small though.
