I have just become involved with packet radio, using a TAPR TNC 2.  My question
is, what is the latest software revision available for this TNC (mine is dated
1986) and where could I obtain it?
Thanks.

This wasn't meant to be a funny comment. I think that it's unrealistic
to expect commonly used voice rigs to be suitable for high performance
data transmission. We see this same problem at VHF/UHF when people insist
on using voice radios for data communications. Alinco made a half hearted
attempt at a data radio, and Kantronics has done much better with their
D410. You don't expect a voice radio to be a good ATV rig and you shouldn't
expect it to be a good data rig either. Different modes need radios 
optimized for different characteristics. Radios that use the Collins
mechanical filter, or it's equivalent, have a pass characteristic more
suited to data use than the current crop of amateur consumer voice
radios. Yet a Collins filter can be had for $30. This isn't so much
a cost issue as a design issue. One size does not fit all. I suggest
that the path we took with the 56 kb RF modem is the direction that
high performance RF data transmission must take. That's to make the
modem the radio. That way it is optimized to the characteristics of
the modulation used.

Piccolo and Clover are not PSK, but they also aren't a single 300 baud FSK
carrier either and they are illegal under the current rules. Transmission
of multiple carriers in the same band by the same station is forbidden.
The rules weren't designed to handle this case. A simple bandwidth
restriction without other constraints on signaling method would make
more sense. Note that while Clover occupies a bandwidth of about
200 Hz, Piccolo occupies a bandwidth similar to a AM voice transmission.
It's thruput is high of course. What I'd like to see is a realignment
of the rules to concentrate on bandwidth restrictions only. Thus a
Clover or CW or FSK signal would be ok in the narrow bandwidth subbanda
and voice, SSTV, and Piccolo and the like would be ok in the wider
bandwidth segments. Concentration on modulation *methods* rather than
modulation *results* make the rules unnecessarily restrictive. This
doesn't leave a place for SS, but then current rules don't either.

Summary: Problem solved.  Use 0.1uF cap and 2200 Ohm Res.
Organization: Texas A&M Univ., Inc.
Date: Sat, 29 Aug 1992 23:14:12 GMT


Concerning my previous post, I have it working now.  As I mentioned, I had
used various values for both C and R.  However, I wasn't able to use the
suggested 2200 Ohm resistor since I didn't have any.  I bought some today.

To make a long story short, the key to getting this to work is to use
0.1uF capacitance and 2200 ohm resistance.  When making the connections,
make them as short as possible (mine are 1/8" long leads now).  Once I
did this, the 727 worked fine.

A side note:  the 727 uses a 12V battery pack (12.5 actually).  The
Yaesu charger/DC supply does not supply enough current to drive the 727
at full power.  I am using a 13.8V DC (auto "12" volt) supply to run the
TNC and the 727.  I tweaked the output voltage to 13.25 (from 13.8) and
it can supply the 727 with as much current as it needs.  This was an
important fact when using the HT -- if it doesn't have enough juice to
transmit, the packet's beginning will be lost.

Thanks to all who responded!

     Princeton's BITFTP gateway still exists but it's been closed to everyone

     There's another such gateway at decwrl which was still operating as of

address you poke to make decwrl emit its help message.

With the likes of BP8s it is easy to get it apart, just unscrew the
screws and pry the halves apart.

Several companies make pre-made "inserts" to replace the cells in
these packs.  Periphex has been my favorite at 800 634-8132.

The newer "S" series of packs are ultrasonically welded and cannot be
fixed, at least they were not designed to be.

transmitter buffer size from 8K to 4K (is it still too much ?)

The assembler source is included with the package.

Importaant note: if the driver does not work on your PC
boot it with minimal config.sys/autoexec.bat

that the driver would not work unless he removed from autoexec.bat

The only commercial products I'm aware of that run at reasonable speeds
for reasonable prices use Gunn-diodes doing direct FSK on 23 Ghz.  They
are microwave Ethernet transceivers.

Bdale and crew were working on doing something similar - the goal is to
have a box that you can plug into a PC(or mac, or sun)'s Ethernet hole,
and point its antenna at a similar box, yielding a highspeed link.

I think they got up to about 3mbit a year or more ago.  Dunno where it's
gone since then.

However, RCE and his crew have shown that this kind of performance is
probably ONLY available on point-to-point links unless you use some
sort of spread spectrum scheme that can deal with multipath, since in
any non-PtP application with high-speed data, the multipath just chews
the life out of your bitstream.  Even 56kb at 433 MHz dies from that.

Note that a repeater system can be equivalent to a PtP link, since each
participating station points his directional antenna at the repeater.

Greetings all...

There was a message on the local PBBS's that one of the groups in our area
(Phoenix, AZ) is going to shut down all their BBS's, nodes, etc. over
the Labor Day weekend to protest the ARRL position on unattended
forwarding. They seem to think this will "send a strong message to the
ARRL".

Seems kinda stupid to me. Seems like they will be only proving that the
world can get along just fine without packet forwarding, which I would 
think is exactly the opposite of what they want to show.

Is this a widespread protest this weekend or just an isolated group?

With these few cycles it gets hard to demodulate such a transmission unless
you know something about it.  For example, one could use one of many
self-clocking techniques.  How about maybe XOR-ing the intended data with a
repeating pseudo-random sequence everybody agrees upon, maybe, say at twice
the bit rate?  Sounds a lot like DS spread spectrum...

I don't know what Al means by "advertising", but ucsd.edu acts as the
nameserver for the ampr.org domain. Because of the unique nature of 
Net 44, finding an Internet address for one of these nodes doesn't
guarantee that you can actually reach it.

But sometimes you can. As a couple of other people have mentioned,
there are some gateways between the Internet and AMPRnet. Then there
are situations like my (now outdated) "mac.n6bis.ampr.org" listing,
which has an ampr.org name but was actually on Net 129. In other
words, it was reachable over the Internet, but not over amateur radio!

Is everyone sufficiently confused yet? :-)

    I use the HP95 with a PacComm HandiPacket and a
Kenwood HT 27A. It is a very compact setup. Beware
an error in the Buck Rogers article - the receive and
transmit data pins are crossed ( 2->3 & 3->2, not 
2->2 & 3->3 as shown there). The main point he makes
is correct: you need to tie pins 7 & 8 together on 
the HandiPacket because of the lack of hardware 
handshaking on the 95. Once that is done, works fine.

I've posted a couple of articles in the past about our attempts here in

and a similar Metropolitan Area Lan.

We've now completed the first phase of the system, and have a backbone
linking Dayton, Cincinnati, and Columbus through a set of 19.2KB
point-to-point links (5 node sites in all), and a full-duplex 19.2KB
packet repeater running in Dayton (currently with 6 users).

The system is built using the Kantronics D4-10 UHF DataRadios.  It
works.

I won't take up a lot of bandwidth here with a lengthy description, but
if you're interested I'll happily email info about this system.

Strictly speaking that's not completely true. CW is a digital mode
and it is permitted *anywhere* on the amateur bands. Then there's
SSTV, it's not voice, but is allowed in the voice bands. In fact
it's only allowed in the voice bands. SSTV is an interesting case
as well because it is in practice a digital signal transmitted by a
frequency and amplitude shifted carrier. That's because all current
generation SSTV equipment digitizes the video in a frame buffer.
It uses a 64 kb buffer that is transmitted in an 8 second frame
for an effective thruput of 8 kbs. This looks like a dodge around
the antiquated rules. We could load the frame buffer with data
and transmit it as a SSTV picture. The FCC doesn't require the
pictures to make sense when viewed on a monitor, except for the
ID every 10 minutes.

Even better, if we write the data in columns, read it out
for transmission in rows, and use matrix FEC, we have a rather
robust data system that should be able to shrug off burst errors.
This the way D2 digital videotape recording is done. When
the matrix is reconstructed, errors are smeared out across the
matrix so that the check bits for each row and column can be
used to reconstruct the damaged data.
