I'm running a Clover port on my BBS.  This is on the Civil Air Patrol Digital
Network.

Our National Clover Network consists of 22 Clover equiped BBS, all operating
on 7.920mHz.

How well does it work?  After using it for six months, I think it is one of
the slickest things I've ever used.  We pass traffic overnite that used to
queue for days or weeks waiting for a good opening on the same channel.  It
works better than HF packet, AMTOR, PACTOR, and as far as I can see, better
than G-TOR.

There's a good article in QST regarding exactly what you are asking
about, this month.  Look at the AEA PK-232, the Kantronics KAM, to start;
these are far and away the most popular TNCs.

Except for the TNC, which isn't all that expensive, you have everything
you need to get going!  Digital is great!!

"...MUCH software available for it..." but what about the difference between
Quality and Quantity? Just how many word processors, terminal programs,
spreadsheets, etc, is enough? Sometimes more choice means more choice among
better products, but not in this case. The best PC/Windows software are
ports from the Macintosh. I recommend you choose a Macintosh, I did 5 years
ago and love it.

Unless there is some reason you CAN NOT use a Macintosh, a Macintosh will
never bother you about video drivers, video modes, mouse drivers, "real"
mode, AUTOEXEC.BAT, CONFIG.SYS, Extended Memory vs. Expanded Memory, memory
managers, HIDOS, IRQ conflicts, CD-ROM drivers & cards, sound cards, and the
magical 640k limit.

You would not want a Macintosh if there is one particular software package
you need to/have to/want to run. One of the things I do at work is write
software for embeded 68HC11 based systems, on this Macintosh. The editing
and compiling environment on the Mac is the best that can be found
anywhere. I use the same Mac to draw the embeded system's schematics,
layout and autoroute PCB's, parts lists, documentation, everything except
in-circuit emulation. The Nohau emulator is hosted on a PC, as is my EPROM
programer.

Additionally, (at least with the Powerbook 180) the accessory video port may
drive either a second monitor, or a copy of the LCD. The difference is when
you have a second monitor, both the LCD and monitor are running at the same
time and your "desktop" is expanded to the sum of the 2. The mouse slides
right off one onto the other. If you want to see a big drawing, just stretch
it across both monitors, the Mac's operating system will take care of it,
the application doesn't have to know. PC's can not begin to do this. Macs
support up to 6 monitors at once. I'm using a 21" 24-bit monitor, a 19"
1-bit monitor, and a 14" 16-bit monitor on a Macintosh IIvx. No video
drivers. No jumpers. No hassle.

On the other hand, Unix is often chastised for being obscure, complex, and
difficult to maintain while I've found Unix to be much easier to maintain
than PC's, MS-DOS, and Windows. And a PC running Unix presents the worst of
both worlds. Rarely does a Mac run Unix, but it can, and DOS also, at the
same time.

Subject: HP100LX + Baycomm = Success?
To: [e-mail]

Has anyone had any success using a Baycom type modem with the HP
100LX palmtop? Before I go out and mess with it, it would be good to
know if it is possible or not. The Hamcom interface I built wouldn't
work with the 100LX serial port, and so I am now skeptical and would
like some reassurance before I invest in the parts to build an
interface for Baycom.

To: [e-mail]

Just go buy a KPC-3 works good tastes great.
Seriously I used to use a Baycom from Tigertronics.
It is a memory hog and likes power. I don't
think the added cube of the KPC-3 is enough to
warrent the hassle of the Baycom. The KPC-3 runs
forever on a lithium 9V battery. My mobile com
program is a freeware item called pax. The only
real advantage of the Baycom and associated software
is the lower box which shows all packets received
so you can sniff the call of a local BBS when in a
new area. You can do this with 'passall' and 'trace' with
other modems. Pacom also makes a pocket sized modem
with a nicad internal however I have spent a great deal of
time trying to get there stuff to work and am not yet
impressed. Hope this helps. When you get on packet de

I have looked around quite a bit and about the only software that I have
found that supports the FAX and SSTV modes for the MFJ1278 is MFJ's
multicom program.

Ned,
If you are that close to the backbone, have you ever considered setting up a
node of your own?  I suspect if you have poor 2m reception, others near you do
too and might be interested in helping you.

Just the thoughts of a lunatic near the full moon!

Hi all!

    I was just looking through my EEtimes rag and came accross an as

TMS320 DSP on it.  Is this a good (i.e. complete w/t d to a and a to d
and amps) kit for voice filtering and Frequency displays?

Gary,
We may have to watch the term broadcasting.  The FCC takes a dim view of
broadcasting in amateur freqs.  Now don't get yourself all bent out of
shape - and don't go grabbing your Part 97 and flaming me with quotes from
the current regulations.  I am just pointing out that while the broadcast
model uses the frequency more efficently, the FCC may not like the hoards of
HAMs using it without special permission.  I personally could do without
the FCC knocking on my door with a NAL.

I suspect special arangements would need to be made similar to the ARRL's
for broadcasting their code practice & such.
