John, Stefan, LF!

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.
