I am looking for a place where I can find the Poor Man's Packet
modem (or some similar device). I have tried to e-mail and write
to the person who supposedly can sell me the kit for PMP, but I
have had no response. Can someone point me in the right
direction?
Thanks! Jeff

Gentlemen:
You want to SHORTEN the PLL time constant. The highest frequency
that can be modulated is related to 1/time-constant!

To: ham-digital@ucsd.edu
Just uploaded into ftp.ucsd.edu /hamradio/packet/tcpip/incoming as
'conversd.v1.4A.tgz'
*** THIS IS AN ALPHA VERSION 1.4 ***
This is a version of conversd 2.55 that with distributed with WAMPES 931001,
its since been modified to include a great number of new features.
Linux is the only supported OS at the moment.
This is a redistribution of the standalone package, it does not specifically
require the WAMPES931001 distribution to be run, it *should* work with the
latest version of WAMPES just as well.
To hopefully be found in /hamradio/packet/tcpip/wampes/.
Many Thanks go to the WAMPES team for producing the original code.

I've called the KaGold BBS # a dozen times to download a copy of their

Is there any such beast as a mobile-mount 12VDC packet
TNC? Hopefully something the size of a mobile mount
xcvr or smaller.

Subject: New UK TCP/IP mailing list
To: ham-digital@ucsd.edu
Hi folks,
There is now a mailing list set up for the UK TCP/IP Networking Group
(UKIP). This is a loosely-organised group set up to promote the use of
TCP/IP networking protocols over radio in the UK, and to encourage the
establishment of high-speed backbone links and network gateways.
If you want to subscribe:
Send mail to ukip-request@cs.nott.ac.uk. This is handled by a
human rather than a listserver, so be polite :-)
To post to the list:
Send mail to ukip@cs.nott.ac.uk. Subscription requests and other
administrative bits and bobs should go to ukip-request, _not_ to
the list as this just means that lots of people read your
subscription message and get cross.
Have fun! I hope to see lots of interesting discussions happening very
soon.. *grin*
By the way, the next UKIP meeting is to be held on the 15th October in
Nottingham. Details to follow..

Subject: new version of dsk-loader for the macintosh
To: ham-digital@ucsd.edu
I uploaded version 1.1 of my TI-DSK loader for the apple
macintosh to the info-mac archive (sumex-aim.stanford.edu and his mirrors).
It can be found in /info-mac/app/dsk-loader-11.hqx.
you also can ftp it from oak.oakland.edu (/pub/hamradio/mac/digital),
and from ftp.funet.fi (/pub/ham/dsp/320C26).
Here is some information:
DSK_Loader 1.1
DSK_Loader is the Macintosh equivalent of the DOS program DSKL. With
this program you can communicate with the DSK (DSP Starter Kit) from
Texas Instruments. This program bootloads a simple communications
kernel and then loads other software using this kernel.
Other options are:
* Fill DSK memory with a certain value.
* Dump DSK memory into a textwindow, for further processing.
* Execute programs on the DSK.
* Graph output from the DSK.
* Act as a dumb terminal to the DSK.
changes since version 1.0
- fixed crash when scrolling in 32 bit memory mode.
- fixed hangup of PowerBooks when downloading to the DSK.
- enhanced graph window with offscreen update, grid, and
background which can be selected by the user by setting
misc options.
- some cosmetic enhancements, better errormessages etc.
- added a few more .dsk files.
The DSK and thus DSK_Loader is most interesting for people who want to
experiment with Digital Signal Processing at low costs. For HAM-Radio
operators it is a very interesting piece of equipment, Some
applications, like the KC7WW port of the W9GR filters are included.

Subject: Off the shelf modems for packet?
To: ham-digital@ucsd.edu
The pc modems that are "SoftModem Technology"
are now reasonably priced IMHO, and should be reprogrammable
for the modulation standards of the radio and TDD worlds.
This would allow "off the shelf" hardware, but we need custom
software. These modems download the DSP program from the pc.
The Digicom DSI Connection and the similar Cardinal MVP144DSP.
use ram program storage, not flash-eprom.

Subject: Question: Variable Baud Rate Modems/Packet
To: ham-digital@ucsd.edu
I don't know how to ask this question in general terms but I l'll do my
best....
I am looking for information or a source to get specific information about
changing a modem or Packet Terminals baud rate to an odd baud rate (such as
2500 baud, 1600 baud, 1250 baud etc.).
The real question is:
Does this require hardware modification, software modification or both?
I am mostly interested in packet modifications but anything relating to
modems will work. I can apply the theory (I hope) for modems to packet.
ANY HELP OR INFORMATION ABOUT THIS WOULD BE GREATLY APPRECIATED.
Thanks, Mike

Subject: Ramsey Kits for 9600 Baud pakcet?
To: ham-digital@ucsd.edu
Has anyone out there used the Ramsey FX line of VHF and UHF radio kits for
9600 baud paket? Ramsey advertises that these radios have a dedicated packet
connector (5 pin DIN). Does this work at 9600 baud or are modifications
necessary?
In general, would this be a good radio for experimenting with packet?
Are there any other kit manufacturers that offer similar radio kits?
Thanks in advance,
-Ross
(still awaiting my call sign)
BTW: Is there a list (available via FTP or otherwise) of public access
NNTP servers? The server my college connects to by default doesn't work
very well and also doesn't receive many of the newsgroups.

Subject: Whats the theory on the DCD state machine?
To: ham-digital@ucsd.edu
Can some one explain the theory behind the DCD state machine circuit!
What is significant in the HDLC data stream that this thing keys in on?
How does the circuit typically interface to a TNC. I've never
seen the schematic or state diagrams, so perhaps what I am asking
is obvious given those. Looking at the schematic of the PK88, it looks
as if it would replace the modem chip's (AM7910) carrier detect output.
Or would the circuit just gate the RX Data to the SDLC hardware?
Questions, questions, questions!
I don't presently have one, but I would like to understand the theory,
and then add one to my PK88! Thanks!
