Hi,
As there are some German GSM experimenters here, what happened to your demo licenses after the DECT guard band frequencies had been auctioned away to AFAIR Vodafone? What a stupid idea, they did not listen to the technicians and just had the $$$ signs in their eyes :(
I got a reminder last week, my license would expire soon, and if I would like to renew it. So I answered intentionally unknowingly "yes, please do so". Let's see what they will do now :) The second possibility would be asking the management of a German provider if they would lend me one of their unused guard channels. Although I see there chances I really would hate pulling this wire...
Ralph.
