Subject: Amelia Earhart
From: ron.chester@lst.spacebbs.com (Ron Chester)
Date: Sat, 12 Feb 94 23:30:00 -0800
Tonight I saw the last half of a PBS show on Amelia Earhart which I
believe most DXers would find interesting. (I missed the beginning, so
don't know the name of the program).
According to the show, Earhart did not especially like radio
communication, and did not get properly trained up on radio navigation.
For her final around-the-world flight in 1937, she left her Morse Code key
at home, as she had never managed to master the code. She also did not
take along the airplane's trailing wire antenna, which she found hard to
use.
The trip was successful for the first 40 days, until they got to the most
difficult leg, which was the long flight over the Pacific from New Guinea
to Howland Island. The program asserted that the failure of this leg was
primarily the result of the lack of radio expertise on the part of both
Earhart and her navigator, Frederick Noonan. Among other things, there
was confusion on their part about what radio frequencies to use.
The Coast Guard had the cutter Itasca stationed at Howland, ready to
assist her in finding the tiny island. As she approached Howland, they
picked up and logged her radio signals as she asked for help. She was
circling all around the vicinity of her destination, but was unable to
spot the island, while running out of fuel. The Itasca heard all of this
clearly on their radio, and transmitted back to her over and over on three
different frequencies. But Earhart apparently never heard the Itasca
signals, and eventually disappeared into the QRN, never to be seen or
heard from again.
It was a fascinating account. Catch it if you see it in your TV listings.

Actually, Steve, Bruce asked the newsgroup if we wanted to have these
posted here, and I for you replied that I thought they were a good
idea. I like knowing what is happening at the FCC though I lknow it is
of little use to many. There are a number of informational posts that
are not of interest to all the amateurs in this newsgroup but that
doesn't mean they should be run off.
Please keep posting the FCC digests.

RWM
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.
JWA
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
of the Sound Blaster 16 with ASP. He is WRONG.
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
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.
JWA
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
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.
JWA
New information places the Hamblaster at about $275.00
RWM
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.
JWA
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
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.
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.
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.
JWA
Good Luck!
Programs for the Hamblaster will also be available on public
domain disk or BBS's.

I've been thinking about this a bit today (a dangerous thing to do!)
and I guess that the real issue is whether it is appropriate to run
a QSL manager operation for profit. I guess that a few managers make
a few bucks by managing QSLs for a DX operation, but it's generally
considered a public service to the amateur community.
I personally think that it's wholly inappropriate to charge upwards
of five times cost for the privilege of receiving a QSL card, as in the
case for F6FNU. You can't exactly pass a law forbidding it. But,
I recall that the DXAC was soliciting opinions on QSL practices last
year. Perhaps it would be appropriate for the DXAC to disallow DXCC
credit for any operation that utilizes an obviously for-profit QSL
manager.
Just a thought. Obviously, one would have to rigorously define what
a 'for-profit' operation is. In Germany, $1.00 is no longer sufficient
for air-mail postage to the states, for example. But the fact is that
in France, the cost of (reduced rate) air-mail postage is still
substantially under US$1. For-profit QSL managing just doesn't
seem to be in the spirit of DXing or amateur radio in general.

Best luck has been had with a Weller 140 Watt soldering gun with the tips
removed. Grease the braid with rosin flux, pre-tin lightly and re-flux
Install into connector, and straddle the hole in the side with the weller
tips. (This is resistance soldering technique) Feed solder into the hole.
Rotate connector and do the other 3 holes.
I usually solder the center conductor first to hold things stable. Take it
easy with pretinning the braid, if you make it too thick, it will not fit in
the connector shell. Also, for the connector to be "properly assembled" the
cable jacket is supposed to "screw" into the shell body.
Wonder of wonders, when the braid is properly soldered to the connector, and
the jacket is threaded into the shell, the connector is weather proof. Or
at least it is if you use Amphenol connectors instead of whatever cheap
piece of crap you can buy for 25 cents at the swapmeet.
