Hello, All! I have put some recordings of the 144.100 HF cw beacons made using the K2, Linrad, and the SDR-1000 at http://www.qsl.net/w3sz/linradnoise.html Each recording spans the 3 minute beacon cycle. Further Details at that URL. Go down the page to the last section at the bottom and you will see the files and commentary. 73, Roger Rehr W3SZ FN20ah http://www.qsl.net/w3szLINRADDARNIL
