CB interferencee to tv sets in the 70s and 80s

Yes, a lot of people recieved interference from cb radios on their tv
sets in the 70s and 80s.

However, despite what was said recently, the majority of these were
NOT caused by CB radios operating with illegal power.

The majority of interference was on tv channel 5 and caused by legal
power CB radios.

Cable tv did not exist in most areas yet. Cale tv was not even
available here until the middle of 1989.

People used OTA TV antennas back then.

Check the first, second, and third harmonics of 27.185 mhz (CB channel
19)

And check the frequency of tv channel 5.

THAT was the cause of most CB interference to tv sets back then.

It was NOT the CB operators' faults.

Yep, I went thru this myself. I was getting complaints from neighbors,
even though we had cable at the time. A cheap low pass filter from
Lafayette (remember them?) fixed it.

....Yep. Had to install one of those myself on my base station because
the inbred idiot living behind the house threatened to burn down my
house if we bled over on his football games again. We called the cops
on him after my RG-8U got cut one night in four places, but the
******* apparently used gloves because no fingerprints could be found
that matched his. After we replaced the coax and added the TVI filters
from Lafayette, he apparently was satisfied. Until about a year later
and a Ham set up his rigs a couple of streets over, and was running
1KW most of the time. The inbred climbed his fence and tried to cut
the coax *and* the guy wires on his mast, and wound up getting caught
red-handed at gunpoint. After he got out of jail, the bozo packed up
his **** and his kids - couldn't tell between them too easily - and
moved away.

Good approach but not guaranteed to cure it. It's nice that people with an
antenna near their home are identified as CBer's though..10-4 qsk.

(mind the obvious cross posted bait and happy new year anyway)

LOL, wow I didn't have problems like that. My neighbors would just call on
the phone and ask me to stop, which I did.

I was running a Heathkit base station (a GW22 I think) that had 5 (count
em!) channels available via the front panel switch. You could actually use
any channel from 1 to 23 as long as you plugged in the correct crystals!
It was built by my older brother, and I sorta "inherited" it when he got
married and moved out.

Yes, it *was* a GW-22. Picture he

http://www.retrocom.com/New_Folder2/...20%20GW-12.jpg

the one on the left is the GW-22. The controls are off/on volume and
squelch on the bottom, and the 5 position channel selector above. Didn't
get much simpler than this!

In this case it *did* fix it.

....The problem was centered on the fact that Cable Channel 5 in those
days was assigned two channels that swapped off, one for Waco, the
other for Belton-Killeen, and both were MW relayed using some pretty
****ty equipment that was prone to odd WXI - sturm und drang didn't
seem to phase it, but there was this mountain fog that would cause
signal degradation and cause ghost images. One stretch of the MWR went
over a man-made lake that carried heated waste water from a power
plant, and the thermal convection actually played a bit havok with the
MW signal when the temperature was just right - IIRC, ~55-60F. This
was going on for about ten years already when CB showed up, and the
Chicken Banders all got the blame for something that had long been
around and understood. Adding low-pass filters usually did the trick.

....We had one jackjaw who was running massively illegal back in the
Glory Days. Every night from about 8:30 to sometimes as late as
midnight, he'd crank up his 1kw footwarmer, and start spinning his
Moonraker 8 around looking for someone to either QSO with who was
outside the 60mi limit, or for someone to complain about all the
bleedover so that he could zero the beam in on him and effectively
ruin his evening by going into a long 40-50 minute tirade about why
eveyrone should bow down to him and simply shut up and stay off the
air while he ran the channel. When the FCC was called in on him, they
couldn't find his footwarmer because it was elaborately hidden in the
wall with the coax placed so that when the coax was pulled, a string
was also pulled to simulate a short reach of cable. The FCC chalked it
up to just a "finely tuned antenna" but before they ran additional
output tests the agents were recalled in the '77 downsizing, and never
followed up on it. That night, the jackjaw got on and started cussing
everyone out within earshot, vowing to find out who turned him into
Uncle Charlie. and promising to melt their rigs with "10kw" of power
which some ham was reportedly building for him.

....Needless to say, all of us nearby had had enough. One windy night,
we crept to the back of his house via a creek that ran behind it, cut
his guy wires. and watched as a 50mi gust bent the mast, antenna and
all over his house and through the roof. As it turned out his roof
wasn't ensured for damages caused by a falling mast of his own
construction - he thought it was covered under the tree and phone pole
clauses! - he had to not only pay for the full damage to the roof, he
didn't have enough cash to rebuild the mast. Several montns later, he
got diagnosed with testicular cancer, and we never heard anything more
from him after that.

....I remember the GW series quite well. They were one of the reasons
the FCC imposed PLL requirements on all CBs sold after 1/1/77, to
prevent crystal swapping that would produce out of band ops.

CB interferencee to tv sets in the 70s and 80s

Half the teens on my block were transmitting well above 4 watts from
their high antenna towers. I was transmitting at 16 watts on Channel
19 & 16 all the time. Yes, it made Channel 5 a living hell, and
channel 5 was WTTG out of Washington, a popular independent channel at
the time. By the early 80's, most of us in the nieghborhood lost our
interest in SB (interest changed to women)...... kind of a shame,
women cost a lot more to keep happy. But a CB won't keep you warm at
night or take care of your manly needs (unless your a sick
perv)....... so I guess I was 16 when I stopped with the CB nonsense.

54 MHz is channel 2, which gets the most interference from multiple
offenders.
