Topband: noise

[Gary Nichols]

I have in addition to noise that comes on with the street lights and stays
on until the lights go off in the morning another noise that sounds like a
unstable data transmission of sorts and it appears every 36 khz through the
band starting at 1812 repeating at 1848, 1884, etc...any ideas of what to
look for?

Thanks, de gary, kd9sv
