I read the rules Malcolm and saw the "Theme" -
Then I read on and found SOTA operation is equivalent to RIVER operation -
It looks to be a reasonable proposal to have the NA<>EU S2S event on the same day. I couldn't see an explanation for not including the WARC bands, but it is what it is. Presumably antennas are unrestricted, so setting up something with a bit of gain could compensate for the difference between the 30 watts out fairly common in the NA<>EU S2S event and the 5 watts in the QRPTTF.
