While this would be a nice feature, and just about require
digital transmission, it is illegal to encrypt amateur traffic. While
this may change in the future, it is one of those hard and strict rules
that is here today(ie. This isn't like ordering pizza over an
autopatch). You would be better off with Spread Spectrum, since it is
legal, and no one would (probably) even know you were there.

Howdy:
In a recent spate of messages, we have been told of the capabilities
of the hamblaster. It sounds rudimentary so far but I am sure that
over time the capabilities (new software development) will proceed
and its capabilities will be enhanced and it will make a very
interesting tool for amateur radio communications, experimentation,
and learning DSP. There will be alternatives as you will now be told.
In other messages, John Alberts has told us of the lack of capabilities
of the Sound Blaster 16 with ASP. He is WRONG. I received my Sound
Blaster developers kit via UPS yesterday at last. It is easy to see
how John could have made the mistake he made. The manuals received
in the kit describe two distinct pieces of processing hardware.
One is called the DSP and the other is the ASP. The DSP has all
the limitations mentioned by John in his statements concerning
the capabilities of the Sound Blaster card (or lack thereof). It is
a proprietary gate array surrounding masks from other chip developers
to do stuff like DMA blocks of samples in and out, to convert PCM
to u-LAW, 2 or 4 bit ADPCM, CVSD, etc. It directs the flow of
MIDI commands, etc. It is a pretty neat thing in and of itself
but it is NOT what we want. We want a full blown DSP chip, with
a modified Harvard architecture and at least 16 by 16 bit -> 32 multiply,
accumulate, read new coefficient and data in one instruction time.
THE ASP is a real DSP chip and has all this. It is 512 words of off
chip program memory, 512 words of off chip data ram, 192 words of X RAM
on chip,128 words of Y ram on chip. X ram is program and sample
data, Y RAM would be used for filter coefficients. THIS IS A FULL
BLOWN DSP CHIP. It does NOT have the limitations John has told us
the hamblaster overcomes. Indeed, on the A/D, D/A front, it is quite
clear that the under $300 SB16-ASP is quite a bit MORE CAPABLE than
hamblaster. It has two channels (16 bits each), D/A, and A/D. The
sample rate is completely controllable by uploading a divisor to
the control register. The lowest available rate is 5 Khz and the
highest is 44.1 Khz. The processor runs at 12 MIPS so filters would
execute at around 25 MIPS. This is because it has the typical
DSP feature of multiply two numbers, read the next two, and accumulate
the last result while shifting the pointers in two instruction times.
That is plenty fast. I will be able to do dual channel modems for this
card. Since the thing does not also have a UART, or SIO, we will have
to the HDLC and UART functions on the chip when required. Other DSP
developers have done this all on chip (Finland DSP development group
on the Motorola DSP56001). We will be able to do a lot.
John should be more careful when he makes flat statements about
commercially available products. If he were a `real competitor'
of Creative Labs, he could get into a bit of a hassle. I am following the
philosophy of my dear friend, Phil Karn, in attributing to ignorance
when possible, that which could be attributed to malice (in this
case, competition). I told John in a reply to his mail that I
doubted the accuracy of his statements on the Sound Blaster16 with ASP.
I was correct. The Sound Blaster 16 with ASP is available from many
places for under $300. The developers kit is $99, available only
from Creative Labs. In addition to this, you must have a dsp assembler.
The developer's kit provides COMPLETE tools for uploading and
downloading programs to the ASP chip.
I will be writing programs for the ASP and giving them away on your
favorite ftp sites and through the ARRL download request service.
These programs will be the basis of articles for QEX describing the
algorithms and the operation of the sound blaster card in amateur
radio applications. Phil Karn has devised a new link layer for
packet, with FEC, etc. and I will be providing modems that use the
ASP. I believe I can provide what the latest hamblaster announcements
state and more in short order after I get the assembler for the
ASP. I will do this as quickly as possible. I am a bit miffed that I
stopped developing the Windows and DOS front ends and display stuff for
the SB16 ASP after John's note because I thought the SB16 was too
limited. Now it is full steam ahead.

For future expansion, the Hamblaster has an expansion connector.
Several add-ons will include, a better A/D-D/A, Packet switch,
real time tuning scope display driver and a microprocessor.
RWM
In other messages, John Alberts has told us of the lack of capabilities

JWA
Not really, because I own one, I was refering to the
Soundblaster Pro. Any referances to the ASP version
was based on information from the "Ultimate Soundblaster
Book" that I purchased from a local book store. I was
unaware and the book didn't mention it's programming
capabilities. I believe my actual words where
"Im not shure but" .
RWM

The Hamblaster comes with 32K of program/data memory.
It will be expandable to 32k of program and 32k of data
memory with a total os 64k words. More than you'll ever need!
Our packet modem software is 3K. It just won't fit in the
Soundblaster ASP 16.
X ram is program and sample data, Y RAM would be used for
filter coefficients. THIS IS A FULL BLOWN DSP CHIP. It
does NOT have the limitations John has told us the hamblaster

Indeed, on the A/D, D/A front, it is quite clear that the under

New information places the Hamblaster at about $275.00

That's great for HiFi work but for Ham use you only need an
8kHz sample rate and an 8 bit D/A-A/D. If you consider pipe-
lining the C25 also about runs 25 MIPS.
RWM

JWA
There's no way that a product made for Ham Radio will compete
with a product that will sell in the millions. In the Ham market
there just aren't enough sales to generate a reasonable profit!
You'll never get rich selling to Hams.
RWM
I told John in a reply to his mail that I doubted the accuracy
of his statements on the Sound Blaster16 with ASP. I was correct.
JWA
Not really. Because of the proprietary nature,
I can't disclose the full picture. When it's
released, A complete package update will be available.
RWM
The Sound Blaster 16 with ASP is available from many
places for under $300. The developers kit is $99, available only
from Creative Labs.
I think the Hamblaster's price will be competative!
They will offer help to third party programmers.

Good Luck!
Programs for the Hamblaster will also be available on public
domain disk or BBS's.

You might want to check kermit.columbia.edu or even better the cpm

Your best bet is to post on comp.os.cpm. There might even be a FAQ for

We have two of them running here in Phoenix. The mods were made by

I have one in operation with a Kantronics DataEngine w/G3RUH modem for

I hope I'm not missing something here, but as I mailed to the original
poster (postor??) I have been using 1200b through the data jack on the back
of the 5100 with my 1278 for close to a year now. Constructing the cable
with the instructions in the manual was straightforward, and I've had no
problems save some deviation adjustments when I originally set it up.
The thing I don't understand about Yaesu's reply is, what does the data rate
have to do with audio level and where it is fed??
