have access to an MFJ 1274 TNC for free. I've been told this is *not* a
TNC2 clone so not suitable for the UIDIGI-ROM swap. That just leaves me
with the question as to whether I'm going to be able to make this TNC
work as a NEWn-N digipeater (fully compliant except the SSn-N is
optional in our area right now). Are there any special things I need to
know? I have some experience with the KPC TNCs, but the bulk of my
"expertise" is with UI-View-based digi operation.</span></font></div>

The 1274 is a derivitive of the TNC2 with enhanced features. However,
it has no APRS-specific firmware and is incapable of callsign
substitution, N-n decrementing and other features requred for APRS
operations. As-is, it can only implement a "dumb" WIDE1-1 single-hop
home-fill-in type digi. <br>
<br>
I believe it can be made to work with UIdigi, but requires some
motherboard hardware hacking as well as the firmware change. <br>
<br>
It can be given "APRS smarts" if used in KISS mode with an external
program (digi-NED, UIview, etc) running on an attached PC. <br>
<br>
<br>
<br>
Off-the-shelf stand-alone (no PC required) alternatives include:<br>
<br>
o The ubiquitous KPC3+ (not original KCP3) TNC<br>
<br>
o The new SV2AGW micro-TNC. This cigarette-pack-sized
USB-interfaced TNC can run stand-alone as a smart digipeater.<br>
<br>
o In the near future, an optional piggyback daughter board will be
available to convert the inexpensive KISS-only TNC-X (USD $50 kit) into
a standalone new-paradigm digipeater. Details at:<br>

P.S. you committed the common error of quoting an email address or URL
at the end of a sentence, and then reflexively typed a end-of-sentence
period immediately after the address. This breaks the automatic
live-link click-to-reply function of most email programs since the
ending period gets quoted into the TO: address on the "send new
message" form creating an invalid email address. <br>
<br>
One MUST leave plenty of white space around cited email addresses and
URLs (preferrably quote them on a separate line for easy
select-copy-paste) to avoid this problem. <br>
