Re: 2.4GHz QRM



Most 2.4 ghz phones use channel hopping.  If you left
your transmitter on for 1 hour, it may not bother the
2.4 phones very much.  
Unless they are in the same building you are in or
apartment complex.  The phone users would usually not
know it was you.

A Microwave oven will jam 2.4 phones also.

Trying to intentionally jam 2.4 phones is not
recomended.

I like the suggestion of telling them that you can
hear them (very simple and true).

Another option is to suggest they use 5.x ghz phones.
Tell them that 2.4 will jam their WIFI and 5.x will
not.
