Cordless Phone Interference This article has been edited for length it is available in it's entirety at: www.n7viv.com/interference.htm
On March 20, 2000, a carrier appeared on 147.000 MHz at or about 9:00 to 9:15 P.M. MST in Boise, Idaho. This particular frequency is the repeater frequency for Mt. Harrison repeater located 200 miles SE of Boise. But the signal wasn't coming from Mt. Harrison. It was a low power signal coming from Boise, Idaho. I located the signal coming from a house at 3691 N. Jullion St., Boise, ID 83704. AC7BF, came at my request and also DF'd the transmitter to make sure I was correct on the location. There wasn't anyone home so I went home and did some searching on the internet. Armed with a phone # I called and asked for Ben, the owner of the property. I introduced myself to Ben and asked, "had he recently got an amateur radio license." He told me, "no do I need one?" I then explained to him that I had tracked a radio signal and it appeared to be coming from his residence. I asked him if maybe he had recently got a new piece of electronic equipment that might possibly be transmitting accidentally in the amateur bands? He said the only thing he had, was a cordless phone but he didn't have a radio. I mentioned the antenna I could see up on top of the patio roof. He said that was the antenna for the cordless phone. He said it was a "NOKIA" and it had a five ( 5 ) mile range. I had never heard of a cordless phone with a five ( 5 ) mile range. Ben invited me to his home that evening at 9:00 P.M. MST to look at the cordless phone and check it out. I accepted. Well as it turned out the cordless phone was indeed transmitting in the two ( 2 ) meter band. Myself, N7VIV and KB7SYC both had our frequency count
