Not sure if all of you have noticed, but Ossi, OE5ODL is providing such a signal nearly all the time around 137775. It would be ideally suited for Stefan because it's very well outside the so called "Near-field" and thus giving "true" results. Stefan, if you need such a signal for test purposes just get in touch with Ossi, I'm sure he will be glad to assist. 73 OE3GHB Gerhard Am Mittwoch, den 17.08.2011, 19:09 +0200 schrieb John Rabson: > Mal, > > > It's called “stepwise refinement”.
