(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. -Ron K9AGL ------------------------------ Date: Mon, 14 Feb 1994 19:25:16 GMT From: ucsnews!sol.ctr.columbia.edu!howland.reston.ans.net!europa.eng.gtefsd.com!news.umbc.edu!eff!news.kei.com!uhog.mit.edu!nntp.club.cc.cmu.edu!cantaloupe.srv.cs.cmu.edu!news@network.UCSD Subject: Central Ohio ARES contact?

Here are my comments JWA= Jack Albert RWM= Pobert W. McGwier ------------- 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. --- Jack Albert WA9FVP Fellow Radio Hacker Tele (708) 378-6201 Tellabs Operations, Inc.

A couple of green stamps should do it. My >feeling is that if I need the card...right or wrong, I'll send the bucks. > 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.

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. 73 es GM from Jeff Amateur: WA6FWI@WA6FWI.#SOCA.CA.USA.NA | "It is difficult to imagine our Internet: jangus@skyld.tele.com | universe run by a single omni- US Mail: PO Box 4425 Carson, CA 90749 | potent god.
