[aprssig] Quick APRS hardware survey (APRS Hotspot)

[spam8mybrain]

YAAC runs on a Raspberry Pi and has a webserver for this sort of thing (see an example on F5VAG's website, though he's not using a Pi for his webserver host). See the example at http://f5vag.nerim.net/yaacws (a subpage of http://f5vag.eu). Setup documentation at http://www.ka2ddo.org/ka2ddo/YAACdocs/config_transmit.html
Incidentally, why be restricted to a short range on WiFi? Get a Ubiquity Bullet and an omni antenna, restrict it to the WiFi channels in the ham bands, and you can legally cover a few miles with portable antennas on portable masts. My ARES/RACES group does this routinely for a multi-agency exercise in our area

Does this already exist?

A Raspberry Pi WiFi hotspot connected to a local APRS radio.  The Pi is a
server delivering WEB pages to everyone in 1000 feet showing the APRS
tactical situation that the radio is monitoring.

This is for ALL people in the field with hand held devices to be able to see
the tactical situation on their handheld device.  No internet anywhere is
needed.

I am really impressed with what the OUTERNET people did.  The difference is
that their "radio" montors the INMARSAT downlinks (anywhere on earth) and
serve up the content (which includes an APRS channel).
See http://aprs.org/outnet.html

The stock WiFi antenna is only good for a few hundred feet range, but
soldering on a 1.5" piece of wire as the WiFi antenna high and in the clear
easily  got to 1000' radius.  Enough to cover things like Dayton Hamvention
for example.

As some of you know, I haven't been very active in the ham world for the
last three years or so.  That's mostly because a sideline project building
LED hula hoops (https://www.youtube.com/watch?v=Sn-AP8DP254)
really took off. We've moved to a larger shop, hired more people, and
acquired some cool new production equipment, but the
OpenTracker/Tracker3 line has been basically in maintenance mode.

The ADS-SR2 project, that started out as a dual-port successor to the
ADS-SR1 simplex repeater, is my main development focus now. It's snowballed
into a multi-function thing with simplex, cross-band, and duplex voice
repeater support, and I'm merging all of the major functions of the Tracker3
into it.  It has a full-fledged BASIC interpreter with a high-level command
for manipulating voice traffic and APRS packet and support for Modbus RTU
(and yes, I'll probably add
1-wire) for sensors and relays. I've got a partially-working Echolink client
running on it.  It has Wi-Fi support and is web configurable, does IGating,
has a telnet server and client, and can work in access point mode so you
could use your mobile phone to access your VHF-connected mobile hotspot and
do APRS text messaging, and maybe even gate mail from a standard mobile
email client through Winlink eventually.

I keep growing in different directions with it, but I really need to nail
down specs for a hardware version or two and the initial software release.
I'm curious what everyone's most interested in. The full-size Tracker3, the
OT3m, has really slacked off in sales. The embeddable T3-Mini sells
considerably more.  I think the market for a device like the T3 without
network connectivity is pretty well saturated already.
There's a lot to be done in the network-connected device arena, and there
could be a much smaller version, potentially with a built-in 1-watt
transceiver.

What would *you* be most interested in, in terms of new embedded APRS
hardware?  What do you want to accomplish that's too much hassle or expense
with the existing options?
