Do we have *firm* confirmation of the reception of Stefan's 8.97kHz signal=
s
at distance yet? From the evidence seen so far this looks likely, but it
would be good to have the details confirmed for the record books and to
satisfy the sceptics. Even Mal may have a go on 8.9kHz if this test
transmission was as successful as it appears, HI.

What was the final TX and antenna arrangement and what did those who
received the signals use for antennas and receivers?

Bernd told me that many stns have become QRV in the last weeks in the loca=
