site survey for W7TAE?
by Daryl Staehle 01 May '17

01 May '17

Hi- I am in Oso WA, but my shack is on a ridge with a 72’ tower, and I believe I may very well have adequate line of sight down the Stilly Valley to Paine or Marysville. Is there someone who could help me with testing the site before I commit to buying equipment?? 73s Daryl W7TAE From: PSDR [mailto:psdr-bounces@hamwan.org] On Behalf Of Ryan Elliott Turner Sent: Sunday, April 30, 2017 8:43 AM To: Puget Sound Data Ring <psdr(a)hamwan.org> Subject: Re: [HamWAN PSDR] Compatibility. Yes. They'd make a very excellent client node. If you haven't had a survey take place before, I recommend that you reach out to the community and request that. Nothing worse than getting all the gear just to find out a neighbor's house blocks your link.

Yes, that combination will work great. For the benefit of everyone who hasn't started shopping yet, there's a list of many working combinations here: http://hamwan.org/Standards/Component%20Engineering/Client%20Hardware.html Tom On Apr 30, 2017 08:38, "Todd Lilleness" <liltodd65(a)gmail.com> wrote: I have added these to my Amazon cart.

Antennas Mounted Indoors?
by Grace B Thomson 24 Apr '17

24 Apr '17

Hello, I live on the 5th floor of an apartment building in Belltown (98121) with windows facing Southwest. I am on 3rd Avenue, so there are buildings facing me, but I have a clear shot across the Sound to the WNW. I wonder if anyone can advise me regarding an antenna that might work mounted indoors (near the window) that has a good chance of working well. Unfortunately, the building does not allow anything to be mounted outside, so I am limited in this regard. Would it be better to have a device separate from the antenna (Metal 5SHPn for example), or a unit with an antenna built in? If You think an indoor solution is possible, Can You suggest some of the best hardware configuration alternatives. I am on a fixed income, so I am looking for an economic solution to start out with. If it looks like it is possible, I would like to purchase equipment and get this working within the next month or so. Thank You in advance for any thought or advice that You may have. Regards. 73 -Grace KC0BTM NNNN z

hamwan antenna placement
by Harold Kingman 23 Apr '17

23 Apr '17

Hi folks, Looking for some advice. Doing some calculations and I am approximately 12.5 miles SE of Capitol Peak. Situation is that I can put the antenna about 25 feet high on my mast which should just about clear some trees and some high power lines approx. 100 yards away, in line with the peak. Can this work? Or, do I need clear LOS? Thanks Skip K.

City of Redmond "Red.E.Net" Broadband Project
by Ed Morin 22 Apr '17

22 Apr '17

Hi Folks, As some of you know, the City of Redmond received a grant to implement a small broadband system with links to HamWAN. Here is a high-level picture of what we are doing: [image: Inline image 3] The links take a bit of a circuitous route because of the geography (I have spent countless hours analyzing it and testing it in the field). Even this design is going to be challenging to implement, but it seems to be the most reasonable of the various options we have been looking at. Since the grant was submitted, we will likely change the "PSB" (Public Safety Building) node to be on Redmond City Hall ("RCH") instead. (The overall link design/layout and equipment selection is fairly "set," but I'd say the "concrete is still a bit wet" if adjustments need to be made as we get into it.) While I am a Mikrotik fan in some ways, it is too intimidating for "novices" to come up to speed on; some may argue that point, but the grant was submitted implementing this network largely with Ubiquiti equipment (except for the HamWAN links). I also have a Cisco 2911 which we could consider using if needed. Specifically, what we need some initial help with is: 1. Bringing this high-level idea down a level and develop an address allocation plan (we have a class-C subnet on the 44.0.0,0 network) and routing strategy. (We'll keep the Internet peering solely through HamWAN for now, but may set up peering with another ISP "down the road someday.") 2. A preliminary equipment selection has been made (it had to go into the grant budget proposal) and the next step would be to acquire a few pieces of it and prototype one of the radio links simulating linking two of the sites. The best place to start would be the MOC (Maintenance Operations Center) to FS16 because it's a short drive between the two sites and the radio side of it is a no-brainer for the most part. We could start with a simulated setup in a conference room and then take it to the field to try out. 3. As things get tested out and ready to install, we'll need help with both indoor and outdoor installations, but I am not sure how much latitude we have for bringing in non-ARES members to help with. 4. We also have some funds for exploring using something like the Raspberry Pi devices for inexpensive temporary file storage and network monitoring. Developing the scripts and software "glue" to interface with the routers and radios is a whole project in itself. If anybody with network architecture, design, and router configuration experience is available to get together to talk over and do some whiteboard discussion about some of these things, that in itself would be a great start. Taking that down to creating router configurations and testing it out would be the next step. Anyway, this is just a thumbnail sketch. As those who have done this sort of thing before know, there are many, many more details than what I have enumerated here. We presently do not have enough people in our group with the necessary expertise to do this in a timely fashion. I think there may be some other cities that may be interested in seeing how we do this and may wish to use it as a starting point for their own networks. (It would be fantastic if it benefits somebody else. One way or another, linking with our neighboring cities is something we definitely want to keep in mind.) So, if there are a few of you available to help with any of these things, let me know and I'll see how we might be able to coordinate working together. Thanks, -Ed

College Students interested in Mesh Networking
by Katz, Joshua 22 Apr '17

22 Apr '17

Hello, I'm a one of the board members for the K2MFF ARC which is a school club at the New Jersey Institute of Technology. We are the owners of the K2MFF repeater/tower/shack and currently have a stong member base. I've always wanted to setup or use a mesh network. It's one of the main reasons I got my ticket and became a HAM. I had put that aside for some time to work on a few other things (college seems to take up just a little bit of your free time) until I recently found a book in our shack called High Speed Multimedia for Amateur Radio. This group is mentioned within the book. I was interested in knowing what kind of gear would be required to set up a mesh-network base station on our tower that could start routing traffic for other HAMs near us. We have access to some tall buildings, backup power, and fast internet at NJIT. I'm assuming you need more then just a weatherized WRT54G. Thanks for your time, - Joshua Katz

Let's talk about identity
by Bart Kus 10 Apr '17

10 Apr '17

No, not that kind of identity. Digital identity. Used to inform networks and computers about who you are. In my brief research on this, Wikipedia has listed a few systems: 1. SAML 2. OAuth 3. OpenID 4. CAS There are of course other systems, such as X509 certificates, or just plain old trusted keys or fingerprints. The question is, which of these systems are appropriate for use on Part 97 airwaves? The big P97 restriction we have is no use of secrecy or encryption. Early on we realized this means any system which relies on shared secrets (such as passwords) is not going to work well. One system that does work really well is public/private key based authentication. SSH key authentication and TLS client certificate authentication work really well because of this. However, those systems are not without problems. Both of them need to have the encryption option turned off, which requires a custom ssh client and server for SSH, and is nearly impossible to do with any modern web browser for TLS. Other applications that use TLS will also have the same challenge. I'd like to identify some acceptable identity systems for web browsers and web applications. It would be great if they could also be used for email clients (Thunderbird, Evolution, KMail, etc), and other applications like file shares. I haven't looked into security tokens at all yet, but those may work. That is, to plug a token into USB or tap it via NFC (cell phone case), and have yourself identified. Is anyone aware of which systems may be compatible with Part 97 and work in a user-friendly way? --Bart
