HamLAN


Ham radio enabled (more than that - created?  what's the word?) Local Area Network.

A play off the Hamwan folks..

Focus is RF (no direct internet operation - some limited Internet Resource Gateways)

Log in with Captive portal

Messaging via 'groups' even for individuals.

Slowest and resource discovery via APRS 1200 baud.

Others supported:
  regular packet
  soundcard faster packet
  5.9 GHz wifi
  channel -2 wifi
  Ricochet

Use 'real' WIFI for Access and some inter-node content sharing

It's not a success until you're fired.


List the ranges of participation...

Ham Projects 2016



  1. Mobile Data Station
    1. Not new but time to take some ideas from the inbox and make it happen.
      1. Two, or three, portable.  Probably in Home Depot orange boxes.   Two stations is a link, three is a network.
      2. Frequencies
        1. Two meters at 1200 baud
        2. UHF at 9600 baud
        3. Standard WiFi AP
        4. (maybe) long distance Wifi
        5. Portable HamWan node - 5.9 GHz radio
        6. Ricochet Metricom 900 MHz FHSS
      3. Computer ?   (12V, no moving parts, Openwrt?)
      4. Software
        1. WiFi captive portal.  Community groupware
        2. Ham APRS and messages.
        3. Ham TCP/IP - 
      5. Goals
        1. Access home from the mobile via various modes in the Puget Sound region.
  2. xyz

Packet Radio 2016


Data at 1200 baud?    That's plain and simple baud - not Mega bauds or Giga Bauds..   Crazy?  Maybe not.  Much of what we do when Video isn't involved can be handled with slow and simple systems.

If we do it right...

Here's a start of a fresh look at  putting 1980's data technology to real use.



  1. No more than one digipeater.   
  2. Use APRS for resource discovery.
  3. Separate users and data backhaul.  Shared channels cause exponential degregation of performance.
  4. Use full duplex digipeaters for wide area resources.
  5. Use DAMA style resource management. 
  6. Move away from fixed mode hardware TNC's.  Soundcard packet options are here and offer higher speeds and better data simply by changing the software.
  7. much more...

Who's the backup?


It's easy to donate resource to ham projects.   What happens when you don't control those resources?  Who's the backup?   Who's the backup for the backup?

How often do you eat at McDonalds?

Quick, easy, relatively inexpensive.   Why not eat there all the time?

Same can be said for Ham Radio over the Internet...   Quick, easy and inexpensive.  Who needs to bother with silly radios, antennas and all that stuff...


Or maybe it's just like cooking at home..   Better, healthier, learn more, more fun...   It's radio that makes what we do special.  When we bypass the radio - which is so easy to do these days - we lose all the opportunities that make make it so much more.

First Gigabit Link


Purchased a Netgear GS105Ev2, mostly for education about modern networking with VLANS - as described by AREDN.   Secondary was putting it to use right away on the new 'real-IP' home LAN.

GS105E or GS105Ev work.  Other similar models are not 'managed' and will not work.




Put the GS105Ev2 between connection to web switch in the computer nook and the upstairs home computer.  Noticed that both LED's were lit on the switch - left light is 100 MB, right light is 10 MB.  Both is 1000 MB or 1 GB.   Need to check that cable as it might not be CAT 5E or CAT 6.  Regardless it's showing as 1 GB and that's the first I've noticed a link like that even with all the various local network circuits.

It does have a nice web interface. The only trick is accessing it the first time (192.168.0.234?) in order to put it in DHCP mode so it can be accessed on the local LAN. Manually setting a system to the 192.168.0 net should allow access and that initial tweak. The web interface looks like a functional duplicate of the Windows management application.. So outside of the install issues and the byte counters that count bytes (instead of the much more practical petabytes) I'm still giving it a thumbs up.

Mine was already in DHCP mode and all I had to do was query the openwrt router for the assigned address. Pointed the browser at it and there it was.  Thumbs up here too.
