[RFI] Alarm Systems and EMI/EMC

[WA3GIN]

HAHA,


That happens in DC under the TV towers.  Also, some years ago I ran 1kw on 
40m from the mobile. The vehicle was a Isuzu Trooper. Just keying the radio 
up would flip the door locks.  I found the controller for the keyless 
system. It was loaded with diodes which had no bypass capacitors at all.  I 
installed more than 20 caps and that solved the problem. Just for fun one 
Sunday I drove to the dealership. Keyed up the radio and listend to about 20 
vehicle doors locks opening and closing on voice peaks, haha. I told the 
dealership don't know if they ever did anything.

That Isuzu was great for mobile...no significant ignition noise but brother 
the door lock problem took a lot of hours of tender loving care ;-)

73,
