I remember seeing the schematics you are talking about, they were over on
www.packetradio.com. I cant find them now, but they are probably there
somewhere.

Hi Eric,
I'm not too worried about lots of packets perhaps
interfering/colliding with each other. I have a couple of repeater
sites with two controllers. I want to have remote control of each
controller. I don't want to share the RS-232 side. I'd much rather
share the RF side. The circuit was pretty simple. It used diodes
on the PTT for isolation and resistors to mix the TX audio. I'm not
sure if there was any other control or not.

Dave,
I'd like to see that article, too. Connecting two TNCs to one
radio is
easy, but allocating the RX and TX functions between two devices
is hardly a
trivial matter. Unless a buffer is used to store outbound data
while the
radio is busy receiving data on the other TNC, collisions will
occur
regularly. This should be interesting! Is this a good idea?

Hi all
Some time ago, I saw an article on how to connect two TNCs to a
single
radio. Does anyone remember such an article an either have a copy
or point
me to a site where I can download it?
Thanks,
