  OFFICE MEMO          ARRL Digital Conference                Date:6/28/94

The deadline for submission of papers for publication in the Proceedings of
the 13th annual ARRL Conference on Digital Communications has been extended
to July 5, 1994.  Papers should be submitted to: Maty Weinberg, ARRL, 225
Main Street, Newington, CT 06111 or via Internet to [e-mail].  It is
not necessary to present the paper at the Conference for the paper to be
published in the Proceedings.

So, if you haven't already done so, put your fingers to the keyboard and
write-up your software and hardware developments, experimental results,
ideas, theories, philosophy, etc., to share with the digital communications
community.

The ARRL Digital Conference will be held August 19-21, 1994, at the
Thunderbird Hotel and Conference Center in Bloomington, MN, U.S.A. (near the
Minneapolis International Airport).  The main Conference presentations will
be on Saturday August 20.  In addition to the presentation of papers, six
forums are planned covering digital data methods, DSP developments, HF data
methods, TCP/IP developments, ARRL Committee updates, and high speed data
transfer.

For more information call Cathy Thomas at 1-800-726-6715 or write to ARRL
Digital Conference, Paul Ramey WG0G, 16266 Finland Ave., Rosemount, MN 55068,
U.S.A.

Not really. The commented source code needs to be made availeble so that
programmers don't have to re-invent the wheel to add functions to the unit.

Yes, and I have not seen any word of further upgrades in the immediate future.

>Is the AEA DSP unit programmable

Yes, but unlike the Grace unit, AEA does not encourage outside development.
This means that all improvements are written by them ONLY. It took them well
over a year just to get the step outputs working for the PSK Pacsats...

> and if so are programs written for it compatible with the DSP-12?

Unfortunately, no. Although they do use the same DSP chip (56001), their
control processors are completely different, as well as their underlying
operating systems.

I have been using the DSP-12 for three years now, and I thoroughly enjoy it.
If I ever get some time to play with it, I would love to do some programming
with it. You can't do that with the DSP-2232...

I've got power line noise on 20 meters about 50 percent of the time. Is
the DSP-9 capable of doing anything about this? de Rick VE9HF.

                                            The Netherlands, June 28, 1994.
Hello dear reader,

Today I distributed NET_Mac2.3.42.sea.hqx...

For those who don't know NET/Mac...   NET/Mac is the application that
supports TCP/IP over packet-radio, which means, that hamradio operators
can use NET/Mac for their wireless TCP/IP network...

I believe I made some slips-of-the-pen in the 2.3.41 FTP-mods...
Although I have not been able to reproduce all of the bugs that were
reported, I still hope, that 2.3.42 cures those...

In this version of NET/Mac I implemented the following:

- Fix for mods that prompt for username and password
- Support 'rdate' command (see HELP-info)
- Fix error in TRACE-output, introduced in 2.3.41

This version obsoletes all versions of info-mac/comm/net/radio-netmac in
the Sumex-Aim archives.

The new NET/Mac has (hopefully) been uploaded to:
ftp.ucsd.edu, to the directory hamradio/packet/tcpip/incoming.
If it's not there then look at hamradio/packet/tcpip/mac.

It may have also been uploaded to:
oak.oakland.edu, to the directory pub/hamradio/mac/digital

Kind regards,

Adam PA2AGA  (e-mail: [e-mail]  )

I don't know what the difference is, but I could not get JNOS 1.10b to run
correctly when compiled with Borland C++ 4.0. Actually, it seemed to come up
OK but crashed (hung the system) on exit. Based on this information, I never
tried to actually attach any ports or work out the problems. I figured Borland
C++ 4.0 expected the stack frames to be unchanged and fixing it would be a
major bear.

I grabbed JNOS 1.10d and have been running it for a few weeks. In the interim
I ran into all kinds of problems -- users and a local PBBS would
intermittently get a 'busy disconnect' from me for unknown reasons, etc. I
finally traced that to a bug in iface.c (around line 40 the line ifp->flags +=
... should be changed to ifp->flags |= ...). While trying to fix the problem,
I compiled JNOS 1.10d with Borland C++ 4.0 with full debugging information
(add -v to the compiler flags). For whatever reason it's been running without
problems for a couple of weeks. The only changes I've made are to the makefile
to select BC4, and I add the experimental mods for F6FBB style forwarding.
