How do we get the AO-16 packets over to the 144.39 network or to the
internet APRServe?  Several methods.  None trivial.

1) At my old fashiond work QTH, we have 9600 baud old dumb-terminal
network which can establish a TCPIP connection to APRServe.  ALl I do is
use dumb terminal to establish connection and then connect output of my
TNC/PSK1 modem directly to this serial port.  Most of you cannot do this
since you use more modern ISP's.

2) Let the TNC digipeat.  This can work if you are using an external PSK
modem connected to your TNC modem header.  The packet will be received via
PSK and the TNC will digipeat it.  But if you jumper the modem disconnect
header so that the TNC can still transmit AFSK instead of manchester, then
just connect the original TNC output to any 2m radio on 144.39 and let it
go out to the terrestrial network.  

I doubt this will work with all-in-one modems unless you can select PSK on
downlink and separately select AFSK on the send side independently????
Anyone know ????

3) Software!  SOmeone write a program to take monitored packets and then
turn them around and send them out your terrestrial TNC and 144.39 radio.
The ONLY thing required is to insert the "}" at the start of each packet.
THis is the APRS 3rd party protocol.  Trivial to do, but takes a program
to do it.  I wrote such a thing for DOS, but everyone is using WISP...

4) ANy other ideas???
