I think for those areas that do install and 'plan' on a separate BBS packet
channel for bulk traffic, there needs to be a special BBSgate addon to a PC
in that area. Its purpose is to Gateway the very occasional APRS packet
to-and-from the BBS frequency. This way an APRS station that temporarily
QSY's to the BBS or bulk packet frequency would not be totally out of
touch. The BBSgate would:
1) Any APRS packet it heard on the BBS channel it would GATE over to the
APRS channel and insert "FMBBS" in the digi path so that APRS people
would know that that person was over on the BBS Freq.
2) Any APRS message packets heard on the APRS channel it would pass over to
the BBS channel (for any station that it heard there.. just like IGates
do).
Again, the idea is that the user doesnt disappear completely from the APRS
network, just because he QSY'd to pass bulk traffic. His station would
still occassionally beacon there and that should get back to APRS via the
BBSgate.
Of course this add-on code should NOT be added to eveyone's client software
because it would become a zoo if more than one station had it activated. So
this add-on code would only be used IN ONE PC when such a separate BBS/Bulk
channel was designated.
And of course, if we dont bother with the messages, then a simple TNC which
is listening on the BBS channel could simply digipeat APRS packets to the
APRS channel (if any are heard). Then the path would show the APRS world
where he went...
That was the original intent on all packet frequencies back in 1992 when we
first began the APRS concept. And that was that every packet station, BBS,
or NODE would send out an APRS formatted packet 'no matter' what freuqency
it was on. THis way, no matter what packet channel you were on, you would
soon see who all and what all was there (DIRECT ONLY).

Birmingham Hamfest this Saturday. I need help. I'm looking for a TNC
that supports the APRS function fully (uidigi commands, etc). Can you
guys send me input on what brands and models to look for and what price
ranges might not be too bad. I'll (of course) be looking for secondhand
to start. Thanks. 73. Keith. AG4AC.

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 ;-)
