"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.
