Hi, I'm observing the strength of HGA22 since some years. At late evening of 2012-07-02 strong thunderstorm activity happened over E-Germany/Poland/Czech Republic. That's right below the reflection a
Hi Stefan, Start time is 18 UTC, mode DFCW-180, QRG 136.172 kHz, DFCW-shift 75 mHz. ... Strong as usual here at Kiel Canal: http://df3lp.de/misc/ham/2012-07-15_2030s.png gn es gl de df3lp Peter

Mal, Once again you are completely wrong! Real cw-ops would benefit from those sudden enhancements of field strengths lasting typically 1-3 minutes only. (^_^) Peter, df3lp

Roger, Don't worry, that's surely transient; if not try: 1. watching a cooking show on TV (in German!). 2. reading the source codes of ROS, Opera, etc. (recommended). 3. try to dance his call sign (s
Hi Peter, One short burst at around 08h52m. an it looks like same station. ... Confirming that! Look around 03:00 utc at 17.8 kHz. A broadband signal, may be airborne. Peter, df3lp

Moin Wolfgang, Just back from a fun-field-day at M30. Fine, that was my hope. Thanks! Out of curiosity : You aren't building a Loran-synchronized 10 MHz reference by chance ? ... That's not the first

Hi, I found some 10 MHz double-OCXOs in the junk-box and I need two 100 kHz LO-signals at 90deg. of phase shift. The idea is using 74HC390 for dividing down to 400 kHz (25:1) feeding a phase shifting
