[TowerTalk] Weekend from hell

Tue Nov 19 07:14:16 EST 2019

I was first licensed in 1962 and when in the USAF in 1966 I had the base 
commander's permission to operate an electronic entertainment system 
repair business from my on base house. My main parts supplier was in 
town 15 miles  and an expensive long distance call away so I used CB to 
talk to the supplier as well as to coordinate with two partners. A near 
neighbor said nothing to me but turned in a formal interference 
complaint stating I was jamming his TV with my CB.  I got a letter from 
the FCC and had to get a 2nd class radiotelephone licensee to 
investigate and report via a form the FCC supplied.  My equipment 
checked out OK but upon checking the complainants TV it was found to be 
a very old obsolete unit with an IF frequency in the 27 MHz band.  I was 
transmitting directly into his RF chain.  I was not required to do 
anything and the complainant could suffer the interference or get a 
different TV. The 2nd class was a USAF officer who did the work pro bono 
as he was a pilot and I was the instrument trainer operator/instructor 
he came to for 2 hours per quarter.

I was the Director of Operations at the time and we received an interference complaint from a person in Stockton that our signal was getting into their TV. This was unheard of because we'd never had any prior reports. My only tech (small company) was on vacation to I went and visited this complainant. Sure enough, it was our paging signal getting in to the TV.

He allowed it and I found the coaxial cable from the tuner (IF out) was terminated at the motherboard with an RCA connector. The male RCA connector on the coax was pushed in just far enough that the center pin was holding it in but the shield was not connected at all. I pushed the RCA connector all the way in and the interference stopped. I put the TV back together and never heard from him again.
