TAPR could....

TAPR already provides:

  • File repository archives
  • EMail List reflectors -

We Hams badly need, and TAPR could extend their services to provide....

  • Wordpress web sites
  • Wiki  (probably mediaWiki)
  • Computer Discussion Forums
  • Source Control project repository.  Similar to GitHug
    • Issue Tracking
    • Project Planning

Much knowledge and history is being lost as independently hosted sites disappear.

Rather Fight Than Switch - OpenWrt Mesh versions

> I am debricking another router so I can have 3 then I will switch.

Don't switch!

You are running OpenWRT...

You have two working nodes.

Add a third - then you'll have a working mesh.

Install NGIRC on one of the  nodes - WRT54GS with 8 MB would be best if you have one.   It's a well documented process on the HSMM site.

The BBHN GUI is clean and easy - it's a good way to start if you're not used to Linux command line routing and firewall operations.   If you dream in firewall commands - then go for the pure OpenWRT.

With 3 working mesh nodes you'll be able to find a fourth box, install the CHANGEME build and learn how to get it working.   It's way easier to add a new setup to a working system then to try doing everything cold from scratch.

Ok - having said all these nice things about the BBHN GUI - it's also time we move beyond it.  With all the recent activities they're trying to bring the same custom GUI to all configurations and essentially not supporting anything that's not using the GUI.   They've jumped the shark with this one.   The future is pure OpenWrt, maybe Luci, maybe a Ham-Mesh-Luci add-on.   Nobody can hope to keep up with a custom interface on top of all the cool new hardware that's coming.  (It's also important to realize that 'mesh' has a small place in the overall scheme of Networking - to put everything on the Mesh is to throw away much power and functionality.)

Personally I'm going to learn the command line and master the beast - but I'll still keep my old GUI-Mesh boxes around for compatibility checking and loaning out to folks getting started.

HPRAN - High Performance Radio Area Network

A local, experimental, high performance and robust data backbone.

* greater than 100 Mb/s performance.
* robust loss of any one node will on
* optional and controllable - passing OLSRD mesh routing info transparently. Learn how to do this.

* network monitoring such as MRTG or CACTI
* examples -

* Mikrotik radios, 5 GHz, NV2 data
* N or AC mode for user access - ideally both 2.4 and 5 GHz.

Do Next:

  • Access the nodes
  • Better plan
  • Get two nodes linked

Equipment Acquired or otherwise allocated to project
* 6/26 - Fired up Mikrotik radio for the first time.  One of the RB-SXT units.  Set laptop to static IP and it browsed to - Very rich tool set.   Now for a better plan of how to design the system.
* 6/23/2014 - Have RB-SXT radios.  Three DIR-825 for the node switch and access.  Time to power up.
* 6/17/2014 - ordered 2 Mikrotik RB-SXT 5 GHz radios from FAB Corp.
* x/x/2014 - 14xNn $80 Mikrotik Groove from XX
* x/x/2014 - 14xNn $95 Mikrotik 5SHPn 14xNN1 from XX
* 4/18/2014 - 14d41 $46 ECHO58 Echo Series 5.3GHz - 5.8GHz 17 dBi Backfire Antenna from FAB Corp
* 4/14/2014 - 14d42 $54 patch58-19 Tri-Band 5.3GHz - 5.8GHz 19dBi Flat Panel Antenna from FAB Corp

* Complete system will have two full service nodes each linked to two Link nodes
* The services and data on each of the servers will be identica.
* A third server will be running 'at home' to provide hot backup and development
* Full Service Node - all provide the same services with mirrored data
* Running on UPS
* Full size external hard disk of at least 1T
* User Access
* Two Backbone Radios
* Server -
* Asterix
* Link Node
* User Access - one switch with gigabit Ethernet and dual radios on 2.4 GHz and 5 GHz
* Two backbone radios
* DC power - probably 12V

Mikrotik Notes

Q: Dean - If you add lines to a list (say, the "/ip firewall filter" list), they are added at the end.  Then, you can "print" where they are in the list, and "move" them to where you want them.  You can't directly insert, but that's OK.   Where the idiosyncrasy comes is, if you save what you did, and later paste it into the command line (without including the "print" command), it won't work.  Apparently the numbering of the lines (needed for the "move" command) doesn't occur until you do a "print".

A: Nigel - You can indeed place them where you like, using 'place-before=NUM' in your add command, and yes, numbering is dependent on you having performed a

HamWAN Notes

Tom/LXL - With the SNMP stuff I've been playing with for MRTG/Cacti - it's just a read only port. If so, maybe Dean would open that up for you.
It should be enough to complete the snmp section of the client node configuration instructions:
/snmp set enabled=yes contact="#HamWAN on"
/snmp community set name=hamwan addresses= read-access=yes write-access=no numbers=0

Back on Packet - again - wip

D710 on the Linux server - it's not as easy as it should be - yet.

Soup and Cables

Stopped for soup on the way home from work..   Always a treat.  Just
so happens the local 'cable store'  (aka Goodwill) is across the
parking lot from the cafĂ©.   So what the heck - pickin's have been
slim but there might be a WRT54G or something that would work as a
high speed AP.  Or maybe even a Cat 5E jumper.

I was getting bummed when there was Nada for routers.   Nothing.  Not
even those old BEFWRxyz123's...     Had GW gone out of the 'cable
business?'   Can't be.

Ah - relief...   There on the side shelf behind the rack of cables (no
5E's - darn) was the typical shelf of routers.    No 'blue box'
WRT54G's but better yet - had to check the fine print twice but it was
right - a good as new box with all the original parts and pieces and
packing - a DIR-825.  One of the best 'meshable' routes there is.
Luck held and the revision on the box was B1.   A and C aren't OpenWRT
friendly but B1 and B2 are...

Bottom line - keep checking for those cables...

T3-9670 9600 baud data radio

Available in two versions from Argent Data
* T3-9670 Data Radio
* T3 Balloon Tracker - Data Radio tracker with GPS

* Relevant Options
- TXFREQ Ours=440.800
- RXFREQ Ours=440.800
- TXPOWER Percentage Default=100 Ours=10
- USBKISS ON # for KISS mode. Non-standard 3x control-C to exit KISS mode.
# to ping network, change UNPROTO and CONV to send out packets. control-C to exit Convers mode.
* Scott: The TOCALL field can't be changed - it's fixed at APOTxx.
* Scott: HBAUD is ignored for now. When I've had more time to test it, it'll support other FSK baud rates, but it won't do 300 or 1200 baud AFSK.


On Linux:
Plug in
'dmesg' command to see the USB port associated. Mine was /tty/devASM0 ??

On Windows:
Plug in
Find Unknown USB Device
Update software with .INF file from Argent. Full instructions at:
I had to update twice. The first time it wouldn't start.

Wishlist and tweaks:
* Adjustable faster HBAUD speeds
* Change the TOCALL field
* Remove the software carrier detect switch. It probably doesn't apply.

Conversd Server

Another project one of these months...

This is the system (IRC clone sorta) I was talking about.

JNOS has a server built in but the real answer (besides IRC) is Linux.
