Yes, both TNCs wanting to transmitting at the same time is a
problem. I have not thought about it much but there may be a way to
interconnect the DCD and PTT such that when #1 transmits #2 would
hold off based on DCD. There could still be a problem if both
asserted PTT and the same time.<br>
<br>
UIDIGI completely replaces the normal TNC functions with dedicated
ui digipeater functions. With UIDIGI the serial port will not work
with an APRS client like UI-View. It can only re-transmit data
based on the AUX port setup or it can used with a serial terminal to
do UIDIGI sysop functions.<br>
<br>
Another possible solution would be to shutdown the UIDIGI and just
run an APRS client and enable it to do the digiapeater function.
This of course would require the the client be up and running 24/7.<br>

I've seen two radios hooked up to a TNC but I don't think I've
seen two TNCs hooked up to a single radio before; interesting
thought. What would be the implications of them interacting --
i.e. both TNCs want to transmit at the same time?
<div>

<div>I was thinking something along the lines of a TNC 'sharing'
program such as AGWPE or ldsped, replacing the physical
connection to the TNC with a TCP/IP connection for all the extra
features. I'm not familiar with the UIdigi ROM at all but if
the serial port can still be used to connect a computer while
the TNC handles the digipeating, it should work. I think the
weather station already has a dedicated computer that is on 24/7
uploading it's weather to the CWOP servers, so there is some
flexibility there too.</div>

I had a thought on a possible way to solve the local monitor
problem. How about hooking two TNCs to the digi radio? One
would be the present N0CXX-5 running the UIdigi code and the
other a stock TNC connected to a PC running UI-View or
APRSIS32.<span class="HOEnZb"><font color="#888888"><br>
