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).
