Classic example of a CODAR station (coastal ocean dynamics applications radar). land-based, High Frequency (HF) radar. It was developed between 1973 and 1983 at NOAA’s Wave Propagation Laboratory in Boulder, Colorado. CODAR is a noninvasive system that permits to measure and map near-surface ocean currents in coastal waters. It is transportable and offers output ocean current maps on site in near real time. Moreover, using CODAR it is possible to measure waves heights and it provides an indirect estimate of local wind direction.

This video is a bit different from my others. It is of a vintage Realistic DX-300 shortwave receiver, which was brought back from the dead. I had to replace the AC line cord, put in a new electrolytic filter capacitor and also replaced the burned out bulbs with white LEDs. This is a short video of it in operation. These receivers were from the late 1970s into the early 1980s and featured Wadley loop design.
