Can anyone ID this sweeper?

CODAR.

Not sure which one. The ones in NC and NJ use 4525-4550 kHz (NC sweeps up
in freq and NJ down in freq).

I should probably add that in each case above, there is more that one site
transmitting in each state (more that one site sweeps up in NC and more than
one site sweeps down in NJ). The same is true for the Florida system.
This is common for CODAR. Thus a "sweeper" is usually more than one site.
