-* 2009-12-21 I have decided to use DD-WRT instead of the above described installation of OpenWRT. The reason is that there is a so-called "superchannel"-license that permits the use of out of band frequencies in the B and G modes. So it is easily possible to configure the Fonera box to work in the Amateur bands and thus fulfil the requirements as defined by the Bundesnetzagentur.

So it is easily possible to configure the Fonera box to work in the Amateur bands and thus fulfil the requirements as defined by the Bundesnetzagentur.
 ** The Superchannel license costs 10 Euro per device and is thus reasonably cheap to stuff two of them. This is actually the last step to install a really official link between DB0MHB and DB0BUL, since only this license can guarantee that foreigners cannot hack our network and the HAMNET.

		+
		+	** The DD-WRT installation is not really conplicated. There's only one single file that needs to be flashed ("linux.bin") and I decide to install it not via tftp but via http. See above. As level shifter I simply take my 3,3V programmer for Arduino boards.

		+	Here it is in a weather-proof case. In order to protect it from humidity, I simply tool a plastic spray and covered the board with liquid plastic several times. In addition to that, there's the PCB housing and there's also the weather-proof housing on top. It is important to mention that both cases are open to the bottom to allow for condensated water to flow out. It will be interesting to see how it can handle ice in winter times.

-Yeah, I just bought a pair of 1 m diameter parabolic dishes. That will make not only 18 dBi but something around 22 dBi on each side. And I want to place the Foneras directly in the focus of the dishes. So no cabling at all! Let's see how optimized I can get it. So the entire signal will be around
+Yeah, I just bought a pair of 1 m diameter parabolic dishes and a couple of Mikrotik routers with 200 and 350 mW. As only for the antenna, hat will make not only 18 dBi but something around 22 dBi on each side.
-dBm + 22 dBi (- no further cable loss) = 40 dBi
+I don't know how many milliwatts or dbM that will be, but sure a lot.
