Well, not a lot really. You can't reason
with people of low intelligence. On the other hand you can minimise
the annoyance factor by the way you react to them. Nothing you can
do or say will stop them so simply remove yourself from the loop.
The answer is simply "don't get stressed, give stress".
The worst insult you can throw at a jammer is to ignore him. Act
like he isn't there. Act like he is of no importance, which of course,
he isn't. It's hard, but responding in any form means he's won and
you've lost. Instead, take satisfaction in the knowledge that by
ignoring him you are also annoying him.
Jammers have a need for recognition, so don't recognise them. Even
a one word response like "prat" is enough to boost their
ego enormously. If you respond, he's won and you've lost.
If he's a weak signal and is not effecting your QSO, then carry
on as if he wasn't there. Even if you go back with something like
"you're not making it so why don't you give up" is enough
to boost his ego. He's won and you've lost.
Kerchunk jammers can only do it on a repeater that isn't in use
at the time. If it was being used then the kerchunk method wouldn't
work. The answer is as simple as the mind of the jammer, switch
your radio off for five minutes. If he's still there after five
minutes, switch off for half an hour. If he wants to destroy his
equipment by continuously keying it up, then let him.
It doesn't really matter what type of jammer he is, the solution
is always the same. Either ignore him or switch off. Don't respond,
don't get into any sort of conversation with him, don't be a weak
minded moron yourself and get manipulated into his games. Just ignore
him. If you do anything else, he's won and you've lost.
You've spent a lot of time and money on this hobby, don't let somebody
else spoil it for you. You only become a victim if you allow yourself
to become one. Don't be a victim.
"Give a jammer enough rope and he will hang himself".
