We had an incident where a power supply was causing a guys AM stations to buzz. Replaced the power supply with a diferent one, same mode etc, solved the problem.
Doesn't hurt to try.

Hi Everyone
Here's one I haven't seen here before.....
I am in the process of expanding into a new town. The company who's tower I'm using for my APPO is telling me that when my APPO is powered on it interferes with their TV reception - specifically channel 7 (VHF).
I don't know how 2.4 GHz would bother channel 7 (which is what, 140 MHz?) but I know the guy who owns the tower, and he woudn't make this up. Plus
he is sharp with computers/electronics. If he unplugs the power to the
APPO the signal instantly clears up. Plug the APPO back in and channel 7
becomes unviewable.
This is important because his business is a TV store and he uses the off-air signal (channel 7) to demo new televisions to his customers.
The tower is set up like this:
| My Omni Antenna | | 10 feet | ------- His TV Antenna | | | 60 feet | | | | Building with TVs for sale in it -------------------------------
My omni antenna is horizontally polorized, 12 dB. There are no amps on my stuff.
Are there any filters I can get or anything I can do to help prevent this? I can move my antenna to a different location in town as a last resort,
but I'd really like to keep it where it's at. But the guy's main business
where it's at now is selling televisions, and leaving it as-is is not an
option. Would putting the TV antenna above the omni make any difference?
Is there anything else I can to to prevent the interference?
Thanks Everyone! Sam
Update: I also found out that I'm knocking out Channel 7 all over the town. (One of my APs is on the local television tower.....) If I can't fux this I'll have to move that one too, and that would be devastating. :(
