[RFI] Repeater Desense from Tower Light? Or what is it??

[KD7JYK DM09]

"Last night I was monitoring our county skywarn net on 2M as storms went 
through our area...I observed what I thought was a desense hit...I 
quickly realized it the was tower light.  Has anyone seen this or maybe 
dealt with something like this?  The light and antennas are at 400', and 
the repeater is in the bunker at the tower base.   Thanks in advance."

Dealt with?  No.  Observed?  Yes, since the mid-90's, and getting worse 
with old hardware, switching mode power supplies, electronic 
controllers, and LED lights.  The worst was a ~300 hundred foot high 
lone tower in the desert, that radiated hash for several miles from LF 
to VHF.

The same low-quality poorly designed garbage that affects us 
"hobbyists", also affects critical life saving infrastructure.
