Hi,

OOPS! On a second reading I think that I misunderstood
the posting and realise now that the device was meant to
generate an annoying signal for a few minutes 'after' he
had released the pressel. Were it close enough to the
offending station, it would only need to be of quite low
power and limited sensitivity so restricting it to the
offending individual.


That's what I got. To do this @ 455KHz would require lots of antenna
or power. 1/2 mile is very long. I used to interfere with other kids
transistor radios by tuning mine 455 away so that the LO in mine was on
their Rx freq. weeeeoooeeee. Only works a few feet.

A friend of mine was thinking of building a small transmitter that would
put out on 262khz, 455khz (am) and 10.7mhz fm. It was to be a low power
portable transmitter to be used mobile when he got cut off my some
***hole on the road. He could then curse the guy out over his radio
(assuming he had the radio on).

As we all know, one of the intentions of those who seek
to disrupt a channel is to subsequently wallow in the
result of their efforts. This signal then would help
prevent them from enjoying the fruit of their labours.
Unfortunately though there doesn't appear to be a newsgroup
equivalent.

Hi,

The way I read the post is that the pulsing noise would
come out of the rig of the offending individual each time
he keyed-up which puts this 'device' in the urban-legend
category.

Just "pin" his coax.

I guess I always get confused by these posts. What good does it do to
jam the offenders receiver? He can't hear it until he unkeys. If he
keeps getting that annoying tone in his receiver, the easiest way to get
rid of it is to go key down again.

small,,,it was placed in close proximity to his house, within 1/4
mile. When he would key up on ch-19, it would start a audio carrier
that was intermittant,,it was like a pulse for 5-7 minutes, he would
key up again and once again get this pulsating tone, is the best way
to describe it. Needless to say he cleaned up his act, and started to
come around. So now I am in willamette valley and have the same
problem. the person who made that "toy" has passed on,so now I am
looking to get something of the same concept made. Any ideas? JPT.

try taking a look at the ubiquitous 555 timer chip - one could rig the thing
so that it would key up a radio upon recieving a carrier that was above a
certain level - something like taking the signal from the s-meter and using
it for a trigger signal works real well, and ensures that only the local
area gets qrmed. naturally, the interval it keys up for is up to the
builder, with the 555. Another interesting thing is , that if this is placed
real close to the guy's house, very little power will be needed to operate
it. a motorcycle battery would last a long time at a 100 milliwatt
level.......... and if close enough, would give him 20-over s-9. Think i
remember someone doing this once, but cant remember just who it was... G

Kind of sounds like another CB urban legend to me. Usually only the
receiver is mixed with 455 kHz, not the transmitter. And I've found that
most CB LO's are at 10.240 mHz. You could easily construct a transmitter
for that frequency but not legally operate it.
