Subject: [aprssig] HamHud Documentation
Hi All,
Pardon the slightly off topic post. I am looking for documentation on the
HamHud devices. I have been to the websites and the Yahoo group, but can't
seem to find documents that describe it's feature/function and how to use
it. Maybe I missed it. If someone can point me in the right direction I'd
appreciate it.
Thanks
Russ

Russ, the links are there under the "HamHUD II Kit" page.
I'll give them to you here:
Assembly manual for latest kits:
http://www.hamhud.net/hh2/HH2RevE-1_2.pdf
User's Manual:
http://www.hamhud.net/hh2/252_HamHUD_Manual.pdf
Be aware that about 90% of this "updated" manual is good. The only thing
missing is information on the new two-level menu system that was launched
in the last firmware upgrade. When I get some time, I am going to take the
manual and update it for this new function.

An alternative that would be cheaper and more "expendable" would be the
TNC-X with it's piggyback digipeater plug-in board. At $50 a pop, you
could afford to deep-six three or four of these for the cost of one

Yeah, but you'd still need a tracker, assuming you want to beacon position
reports. Once you plug the X-digi into the TNC-X, it does nothing but
digi. The T2 can do both at the same time.

Subject: [aprssig] Signal Locator WEB page
WEB based APRS Direction Finder
APRS has a rich set of Direction Finding tools that have not been
implemented in many APRS clients. As such, these powerful techniques are
rarely used by most operators.
However, if we had a WEB based Direction Finder DISPLAY system tied into
the APRS-IS, then we would not only leverage the power of APRS DFing, but
then ALL ham radio operators in the area could see the developing solution
in real time and we would get 10 times as much data input!
Please see the OMNI-Dfin technique in APRS:
http://www.ew.usna.edu/~bruninga/dfing.html
The web page would draw the map with the overlaping signal strength
contours reported by APRS packets. Browser based stations could also enter
their report on the same web page and add to the display of contours.
This narrows the area down very rapidly to a mile or so.
Any takers? It really does work. And all it needs is input from people
that have or HAVE NOT heard the signal. A reliable NOT-HEARD report is
even more valuable than a heard report, because it blacks out a larger area
of where the signal cannot-be. Enough of these, and you can eliminate so
much area, that it is easy then to focus mnore carefully on where the
signal may be.
I sure wish I knew how to write active web pages like that. TO me, this
would be the biggest asset for HAM radio 3rd to tracking, and Weather on
APRS.

One could do this with an Xastir instance hooked to an internet feed, set
up to do snapshots every XX minutes. Feed that snapshot to an Apache web
server and you've got it.

Can't do that though. One would need a web page form that then generated
APRS packets which would then get injected into the local Xastir server
port. Not terribly hard to do, but someone would need to code up the HTML
and a CGI script (perhaps Perl).

I'm not sure I see what the web has to do with it. Every time I've been
DFing I was mobile, not sitting in front of the computer surfing the web.
Why not use an APRS client that's smart enough to create and understand DF
objects?

Yes, but you are missing Bob's point.. that even *before* you go out on the
road, mobile you can get informaiton from fixed stations on where *not* to
look. Saves a whole lot of time (and gas;-)

Bob's point is that DFing is much more powerful when you can take advantage
of the vast (?) network of amateur home stations who can report at the very
least whether they hear the target (jammer) at their location.
It's especially useful if they cannot hear it at all, because it sets a
radius where the location of the target is more unlikely to be.
If you can harness all those home stations out there, you don't have to be
driving around to get multiple points.
