[GEORGE WALLNER]

As Jim points out: This is non-trivial.
I have not published the details as so far nobody has asked for them.

Indeed, it has to be a serious DXpedition to justify the effort needed.

The magnitude of this achievement technically is to realize that the two modes areworking within 20 kHz of each other, and listening within 10 kHz, and the CW station is running high power!
