WHAS and Cuba heard on 840 Khz.

Here’s another short AM DX clip of WHAS Louisville, KY on 840 KHz. Immediately after the station ID I rotated the loop to the south. The Spanish music heard is coming from Cuba. Both of these are regulars here. This clip demonstrate how effective a loop antenna can be at nulling stations..


1120 KMOX St. Louis AM DX

Here’s a clip of 1120 KMOX from St. Louis as heard here in northern NJ using my SDR PLAY and a DX TOOLS Loop. Plenty of splatter is evident from local Bloomberg Radio on 1130. Top of Hour, (TOH), ID is given along with a local business exchange of 636. This is usually a regular during this time of year. Sometimes it mixes with a station from MA.

Classic example of a CODAR transmission

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.
