Subject: MFJ-1270 A,B,C differences?

Is there a link somewhere that shows any significant differences between
the various versions of the MFJ-1270 TNC's? Is there anything bad about
the original version I should be aware of? I'm getting one this weekend
for free(still not sure which version) to play with and may want to donate
it for DIGI use in the future.

Since there's been discussions recently on possibly incorporating some kind
of Amber alert into APRS in the past, I thought this might be 'amusing' to
the people here.
At 9:29 tonight, the cable tv system in central Mass started putting a
banner over the top of screens notifying people of an emergency,
instructing them to tune to Channel 3 for information.
Tuning to channel 3 yields a screen that says a civil authority in Mass has
declared an alert for the entire state at 9:28 to last until 10:29.
No mention in made on channel 3 what the alert is. (Most assume it's
something to do with weather. A few people even suspect terrorist.) But,
there is absolutely NO info about anthing, other than that some kind of
alert exist, and it will last from 9:29 till 10:29.
At first I thought it was a test run amok. But no, it's real. Seems the
alert HAS been issued, but the people who have issued the alert I get the
sense that they didn't even know they triggered the cable tv system into an
alert mode. Ane the people at the site that apparently triggered the cable
tv interface system, have no idea what is going on. Where it happened,
what happened, why an alert, WHATEVER, other than the fact that there is in
fact an alert.
Geesh, can something be MORE screwed up if they try? Talk about an
incident to totally turn off the public with idiots in charge!
I'm just glad there were no links to HAM radio in this comical but sad act.

Because of the elapsed time of the alert, I would hypothesize that this is
likely a WRSAME test message that wasn't treated properly. The test
messages I've seen are always "effective" for an hour. A good description
of the system and the associated codes can be found here:

r_002/octqtr/47cfr11.31.htm
I could be wrong, but any terrorist alert would've prompted an outcry from
every major media organization, and it should be rather apparent if there's
a weather alert...

Well to defend the "system" .. this was the very first time the Amber Alert
was issued in Mass ... guess there is a few bugs yet to be worked out.
By the way, you were lucky .. my cable company interupted a broadcast in
mid-show for about 14 minutes with full screen non-changing alert text.
During which they played digital recording of a state police officer telling
the details of the Amber Alert .. or they tried to. It kept ending before
it was finished .. so they repeated it (from the very begining!) 5 or 6
times .. but never got it to play to the end .. I think they finally gave
up.

Why is this "stupid" ? It seems like a good policy to me.

I'll just say that it was in fact an Amber alert.
>From a missing persons report at 4:00pm
Now, you can't really fault the time delay because you don't know the whole
story...
But, once it was issued, it took over an HOUR to say what it was.
Turned out it was local to me. Probably less than 10 miles. And people in
this area just got 'something is happening' kind of thing 5 hours and 29
minutes after the fact. Then, they didn't get the actual facts that was
even an Amber alert until they went ON THEIR OWN and dug for them until 6
hours after the fact.
Btw, it was a mother and 3 kids. All in resonably suspected danger.
The system just plain doesn't work. Yet...
Hopefully someones head will roll for this.

Greetings Kirk (and folks)
So far as I know, having made chip sets for most of the TNC's, the original
1270 had only 16K of RAM, a tad tiny for anything other than the original
code, or (say) my "KISS only" chip.
The 1270A standardized I think, the 32K chip, and is ready to go for "APRS
digipeater" use.
The 1270B kept the above RAM, but added some bits and pices that could,
support an optional H.F. display and a real time clock.
The 1270C added more "bank switched" RAM, meaning that if you want to run
the standard (say) UIDIGI code, there are some (very minor) hardward
modifications to make.
I believe that Jeff's (KA9VNV) "questionable website" has all the
information, (right, Jeff ?) try : www.dididahdahdidit.com

In years gone by...I would tout PropNET as *not APRS*. That position
caused too much confusion...in fact: PropNET is APRS with a propagation
tracking twist. The PropNET community has fully embraced the new PHG/
scheme to the point that all stations use it (including our
"digi's"...called Hubs). Why? Because the circuit that we are testing
is the ether, not the ability to pass messages or posits.
You see...PropNET uses APRS technology in a whole new way, with a whole
different purpose...one that thrives on home stations participating.
While boring to many on APRS ('cause the map hardly changes), fixed
location stations provide constant signal sources with which to probe
the ether for band openings (both ionospheric on 20m, 10m and 6m, and
tropospheric on 2m).
This is an outstanding example of the power of APRS. It has the ability
to do many things, limited only by the imagination of those who dare to
try.
'Just taking the opportunity to share some encouragement and broaden the
scope of how APRS is used as a tool.

Sorry, incompetence is not grounds for firing or demoting a civil servant.
And chastising him on a failure might lead to self-esteem issues that
require group therapy. :)
On a similar note I recently signed up for a free Text Alert service that's
supposed to send weather alerts to your phone based on zip code. This
service seems to be on a different "wavelength" and standard to my SAME WX
radio because all I seem to get are alerts for possible funnel clouds one
county to the east of me. No other alerts seem to be issued ever...
I guess you get what you pay for.
