I started operating HF this year and have a 100W station with an EFHW 80-10 antenna. Station works great, but I have a couple RFI issues that I could use some advice on:
1) Even before I had the station, I used the antenna on an SDR receiver. Both my radio and the SDR are regularly overwhelmed by a pulsing RFI signal across all the bands. I can attenuate the noise, but it dramatically impacts enjoyment. Based on pattern of life of the signal, I suspect it is a neighbor's television set. (mostly on evenings and weekends, but not exclusively so. Not timed with sun rise / set, not ever present, etc.) What is the best way to track this down? I back to a number of houses.
2) On the transmitting side, a neighbor put out a call to a neighborhood facebook group asking if anyone was a HAM operator. Needless to say, she didn't want to inquire about getting a license. She is apparently a voice artist and recently bought some new headphones and could hear me clearly in them while working. (She sent a recording.) I obviously reached out and offered any assistance I could provide and agreed to help her troubleshoot. She said she ordered a new cable that is gold plated, but I'm a little worried that won't do the trick. I've had a couple issues with my own computer speakers and an old boombox around the house, but figured that was a proximity thing. I must be interfering with other neighbors as well? Anything I can do other than deconflict with her use of her headphones or suggest she keep trying other pairs?
Thanks in advance!
