I've received this from several sources today. CODAR is that loud swishing sound (30 kHz wide!) one hears on several (of just 5) 60 meter channels. I know ham use is secondary on 60 but I don't think CODAR (which isn't gov't) should be allowed to rip up a good chunk of spectrum. I hear it loud 800 miles from any ocean. Surely it can be heard overseas.
This woodpecker-like garbage is a terrible precedent. Belongs in the Soviet Union. 60 today, maybe 20 or 40 tomorrow.
"60 Meter CODAR Interference - documentation needed - URGENT and IMPORTANT-
All 60 Meter users & listeners,
Recently it has been brought to my attention that a Wave Measurement
Radar System, (CODAR), is causing interference to 60 Meter channels 3
and 4. These systems are deployed in coastal areas and some of them
are operating on or near 5.365 MHz. This is a swept carrier radar
system and the resulting sweep passes through the 60M channels."
