- 04:28, 24 January 2015 Token (Talk | contribs) uploaded "File:CODAR.mp3" (Audio recording of a 4 MHz area CODAR. The recording is done in multiple receiver modes. The first 40 seconds are in USB, the next 40 are in AM, and the final 40 are in LSB.)
- 04:21, 24 January 2015 Token (Talk | contribs) uploaded "File:CODAR pulses.jpg" (Amplitude / time image showing a few pulses of a 4 MHz CODAR. In this case the pulse is about 950 microseconds wide, with a 1900 microsecond pulse repetition interval, giving the fairly typical (for CODAR) 50% duty cycle.)

Remainder of the recording at more "normal" receiver passband widths, as might be heard by most listeners.)

In this case the swpet wdith is still 20 kHz, but the sweep repetition rate is only 25 Hz, so the chirp rate is halved.
