Hmm, it's not international, the 9cm band starts at 3.3 GHz here, and there are a couple of large chunks taken away, auctioned off (I believe being used for WISPs). 73 de VK3JED http://vkradio.com From dlj at bach.altaphon.com Sun Apr 29 21:31:12 2007 From: dlj at bach.altaphon.com (David Josephson) Date: Sun, 29 Apr 2007 14:31:12 -0700 Subject: [Ham-80211] 3.2 GHz?

Our allocations are 3300-3500, but this band is for wireless LANs in much of the rest of the world (typically 3.4 to 3.6, for instance in Germany where it has been auctioned off for commercial broadband), so there is some equipment out there. There is a new band at 3650-3700 for wireless ISP's in the US but very little equipment has been certified for it. W6QAC operates a couple of networks in the Silicon Valley on 3.3-3.5 using modified commercial gear. > > It would appear that you could fit over 20 channels in our bandspace. > http://www.qsl.net/kb9mwr/projects/wireless/allocations.html > > Curious what other details regarding Ubiquiti Networks frequency > freedom technology or further Atheros chipset secrets anyone knows... > that seems the most practical way to go, but transverters are also > possibilities. Ubiquiti radios are Atheros chipsets with transverters onboard. -- 73 de WA6NMF From k8ys at fuse.net Mon Apr 30 00:02:46 2007 From: k8ys at fuse.net (Bob) Date: Sun, 29 Apr 2007 20:02:46 -0400 Subject: [Ham-80211] Reverse sma connectors?

Signal passes through two 12" thick solid brick walls and tthree frame walls. I do use the laptop near a large window and signal fades if I do not. You may need to orient the case so it does not block the antenna. They also sell a decent mag mount with a N connector base which can be used omnis which I have used in my car with some success. Orders less than a $100 are best handled through a reseller such as wlanparts.com 150' is enough for me around the farm but I suspect your WAN is considerably larger. I am planning on trying a 900Mhz solution with Ubiquiti cards next month to try an connect to my office 13 miles away. The topography is not in my favor but with two relays, I might make it.

Like I said, you could give away licenses, but that doesn't ensure people will use them, or stay active with the hobby. I think inspiring experimentation is they key. I got interested in ham radio in the 90's in high school. I remember reading something about The Amateur Packet Network by KC4WZK, and later a classmate brought in a copy of the Now Your Talking. After obtaining my license, I cross paths with a student from my own school on the air. He introduced me to other hams at my school and all the local ham clubs, and activities like fox hunting, etc. There was one club at an adjacent school that we all best associated with. This was the Ashwaubenon High School Tech Club. Around 20 students from that school became hams, and what was unique was that the school allowed a "users group." This group was made up of other students from other local schools (such as I), and it also included other instrumental and sometimes older-elmering members. What was fortunate for us was that these instrumental older-elmering members, were never the type to discourage us by questioning rule interpretations. Instead, they helped us get a repeater going, and later set up "cool" things like a NASA select audio rebroadcast. That type of encouragement, lead to experimenting with SPI and the printer port where we interfaced the repeater controller to the club TCP/IP packet machine, and other unique ideas that we came up with. Now, I happen to work in a school. Every year I give a ham radio sales pitch to administration. And I see the importance of creating that appeal & encouragement in the hobby. We just had a recent ham radio demo/expo here in town. I think the pair of IP phones hooked to the wireless modules got the most attention. And PS. no I don't mind if you quote me, please do.
