Tonight I was tuning around on my Panasonic RF-B45 and heard a "K" beacon with fair to poor signals at 5150 khz (the radio only has 5 khz readout). The beacon was pretty clear, as there were fairly low noise levels. Had a lot of QSB.
Grabbed my DX-390 and found the beacon in a bit weaker at 5153 khz. Was gone during recheck of the frequency at 0945 utc.
