Something to stuff in the idea box, but there is a Wireless router, the
LinkSys WRT54G, that runs Linux and only costs about $85 last time I bought
one. Needless to say, it has been fully hacked now, and folks are running
quite a number of Linux applications on it. Look at this page to start:
http://dailywireless.org/modules.php?name=News&file=article&sid=2432
In any case, that is all well and good for 802.11b stuff, which of course
hams use, but how can we translate this to other ham activities? Take a look
at this page:
http://www.rwhitby.net/wrt54gs/serial.html
which adds two serial ports to the box. Are the wheels turning yet?
If not, let me run a few ideas past you:
Take John Hansen's KISS TNCX, port APRSD or APRSNOS over to the box, and
bang, instant APRS gateway you can drop anywhere there is 802.11x coverage.
Or put one of these boxes at your repeater site and hook it via the serial
port to your repeater controller.
Or slap a STC pactor modem on it and interface into the WinLink network.
Or.... <anything that can be controled via serial port>
You get the idea here, and I do need to note none of the above software
exists, yet the $85 box that could do the above does now exist.
Of course, it does make a nice 802.11b access point as well ;-)

Hmm.. Does this bode well, or badly? I guess Dayton will tell.
BTW: The sig seems incredibly quiet lately.

A pin diode switch can do this, but they aren't cheap, and you'd need one
for each radio.
Filters can do this, IF the frequencies are widely separated.
There may be a "magic coax harness" technique, or maybe something with
circulators, but they are also pricey.

If you can send messages from RF to the Internet, then you are already
receiving messages from APRS-IS to RF (the acks are standard messages).
So, the answer is: gating of messages between RF and APRS-IS is done
automatically by the IGate software. You do not (and you cannot)
specify which IGate gates your messages. Going to APRS-IS, the IGate
that gets the packet to APRS-IS first wins, the others are duped out.
Going to RF, the IGate software keeps a "recently heard" list to
determine which stations to gate messages to. In many metropolitan
cases, multiple IGates may be gating to messages to RF destined for the
same station.
Hope this helps.

If you are talking about off-the-shelf ready-to-run commercial units
that support WIDEn-N digipeating, callsign substitution, dupe
suppression, ec, the ONLY choice is the KPC3+. Avoid the earlier plain
KPC3 -- this is a discontinued unit no longer supported by Kantronics.
As a result, firmware upgrades for modern APRS operation are no longer
provided.
If you are willing to burn UI-DIGI eproms to replace the OEM firmware,
any TNC-2 clone such as the MFJ-1270x series will work.
What you do NOT want is non-TNC2 units such as PK232s, etc. None of
these have any APRS "smarts" that will let them function as stand-alone
WIDEn-N digipeaters. If you intend to use a computer running an APRS
program such as DigiNed or UI-View to provide the brains of the digi,
then any TNC that supports KISS will work.

Yeah, that's what I'm wondering. I just checked HRO and they're not
showing a status on stock.
