| DL6NVC | Dennis | 13.VI.2009 | 00:28 - 00:59 | 0.5 | 539 | JO62RM | 538 | RST 539 at max., Signal was mostly audible over the 31min observing time. Tonight again no local carriers on 500.000kHz, which unfortunately isn't usual here. * ANT abt.15sqm wireloop not tuned, RX-IF BW 150Hz * Thank You! |

Your signal was surprisingly strong and quite constant, varying beetween say 439 and 559 over the 78 minutes observation time. Thanks!

Berlin city. QRG seems to be blocked by a constant local carrier 24h/7d. But isn't there a very gentle, barely audible, "somehow keyed", abt. 2 Hertz interference on this carrier? Yes! Tonight I counted the timing of this interference! Managed to write down the qrss ... -.- -.... .-. ..- -.. and ears/brain even managed to copy fragments of the fast cw sequence! |
