Finally had a chance to connect the antenna up to the radio using the coax running through the conduit from the garage side of the house into the shack. Up until now, most of the operating (what little of it there’s been) has been out in the back yard with the radio connected directly to the antenna.
This weekend, I thought I’d give the ARRL November Sweepstakes (Phone) contest a try. After making a 40m contact Sunday morning, I noticed the network had gone down. Discovered the GFCI breaker for the circuit that our service provider’s ONT box is on had tripped. Not entirely positive it was because of me operating on 40m, because I had made a handful of 40m contacts on Saturday without any problems (that we noticed anyway). Seems likely to be an RFI issue though since the network was up just prior to my QSO.
Reset the breaker, got the network back up, and switched over to 20m but then the wife spotted one of her edge lit acrylic signs flickering on and off while I was making another contact and basically turning it into an “On the Air” sign.
Not wanting to risk messing up anything else in the house by overloading them with RF, I wrapped up the ARRL November Sweepstakes contest with 12 contacts in the log and 240 points with most of my contacts from Saturday evening on 40m (40m opens up pretty nicely out to the West coast in the evenings from here).
I’ve had the antenna up a handful of times since we’ve been in the house, but most of my operating has been outside, so any RF-induced problems there might have been in the house have generally gone unnoticed (except maybe for the time the Nest thermostat died). I’m pretty sure the issue is because most of the antenna lays on top of the roof and on the side where most of the wiring is (electrical service entrance, breaker panel, network router, AC unit, etc). Running 100W is probably causing a lot of RF to be coupled into the house wiring.
So it looks like I’ll have to work on changing the antenna situation. Moving the antenna and mast to the fence on the other side of the house would probably get the antenna far enough away to solve most of problem, but then I wouldn’t be able to use the coax running through the conduit without making the coax run a whole lot longer. The mast would also be on the street side of the house making it even more visible when set up. I could also order a ton of ferrite chokes to put on pretty much any current carrying wire in the house (that could get pretty expensive). I guess I could also take my operations portable and head out into the field or a park.
