From June 1985 BACKSCATTER, newsletter of the Association of
North American Radio Clubs' (ANARC) Over-the-Horizon Radar
Committee:
MAINE RADAR TO START UP SOON
"Test transmissions from the first sector of the US Air
Force's OTH radar in Maine are expected to start this
summer or fall. Listen for loud buzz-chirps with
bandwidths of 5, 10, 20 or 40 kHz. When the bandwidth
is 5 or 10 kHz, the waveform repetition rate should be
10 to 20/second; when it's 20 or 40 kHz, 20 to
60/second."
"The experimental OTH radar was authorized to transmit
in these bands, according to QST (April 80):"
_________________________________________

"Bands used by the operational radar may be different.
It will also be capable of transmitting in the 5000-
6740 and 22250-30600 bands, but will probably be res-
tricted to only portions of the added spectrum. In
general, look for it in the Fixed bands."
