Re: Jammer on Cougar Repeater

Mark McClain

I have a lot of experience with tracking and catching jammers from 30+ years ago in So. Cal.  I've dealt with hams jamming other hams and repeaters, including law enforcement repeaters.  And I have had to deal with some minor occurrences here in the PNW over the last two decades with my repeaters 

The first thing to do is to establish a team, and use a non-public medium (ie- dont use this reflector or any other public or 'semi'-restricted forum.

I'll be happy to share additional info once someone determines how they want to communicate.

As of late we have been experiencing disruption of the club's repeater by an individual.  We refer to this type of person as a "jammer".

This Jammer typically disrupts the repeater between the hours 16:30 to 18:30 Monday through Friday.  These events last about 30 minutes or so and consist of rapid clicking of the mic PTT, broadcasting football games and playing music.  When I catch him at it, I turn the repeater off.  If you have noticed the repeater unresponsive in the evenings - this is why.

I believe this lowlife to be mobile, as I have heard him fade in and out on the reverse frequency (446.825) from my home QTH here east of Duvall.

Under FCC rules we as repeater owners are not libel for the content transmitted by others on our repeater.  We are libel though if we don't take action to stop these transmissions.  Hence the reason I have been turning the repeater off. 

If you have a chance, try listening to the input frequency of the repeater (446.825) during these times, to see if we can direction find these transmissions and locate this jammer.  Hopefully putting a stop to it.
