Congratulations! Actually activity on the 137 at the 137.700 around into QRSS-3/10, 137.777 TA-window, 136.320 EU window QRSS-60 to 120-240. Orient to DF6NM grabber, for example: http://www.alice-dsl.net/df6nm/grabber/Grabber.htm 80m's LW without loading coil is not good idea for all time, for the start only. The other grabber links onto my grabber page: http://qrss.nm.ru/grabber.html Roman * Pieter-Tjerk de Boer <ptdeboer@cs.utwente.nl> [Sat, 16 Jan 2010 21:16:26 +0100]: > Hello all, > > I've added an experimental 137 kHz "grabber" to the Twente WebSDR > receiver.
