OK I understand that first must get to the TAPR site but then what in the devil does it take to get to a newsgroup or SAG? The added forward slashes lock up the system!! Normally one types DIR and uses some ordinary DOS commands, but I have yet to get anything but a flashing cursor for this effort. There is no way of breaking out of the error. I simply have to hard reset the machine which makes the server terribly unhappy. There is something terribly different about the TAPR system and I need some instructions on the proper use. I feel left out and there is just too many good things going on to allow this to continue!

But most are quietly lurking, waiting for something to happen. :-) This list has only been around for a couple of months, and has not generated lots of traffic, but I think it's just a matter of time. There have been several good postings with pointers to sources of information, and some very interesting accounts from some folks who are using commercial SS WLAN hardware. For the latecomers, you can peruse last month's archived postings by sending this request in the body of a message to listserv@tapr.org: get ss jan.96 As for discussion topics, someone just said that "SS is compatible with FM" (or words to that effect), and inferred that most or all of the 70cm band could be used for SS. Anyone care to take that one on? :-) Seriously, interference is an important topic for SS, since no matter where we try to use it, we're going to be sharing the spectrum with other services. Does that mean we should favor FH over DS? Discuss amongst yourselves...

I doubt that you'll see SS ATV on the 440 band because there's just not enough bandwidth available. Spread spectrum works by spreading the bandwidth of a signal out over a much wider frequency range than it normally would occupy. For example, if an ATV signal has a bandwidth of 4 MHz and a spreading factor of 10 (10 dB processing gain) is used, which is relatively small, the resulting bandwidth is over 40 MHz (for QPSK; it's over 80 MHz if BPSK is used). The same problem exists for high-speed packet. High data rates multiplied by large spreading factors result is very large bandwidths. We've gotta go to the microwave bands to make it work within our frequency allocations.

If you will send me a note with the following info, I'll take a look at it and see what I can do: - Type of client you were using (e.g., Unix FTP client, WS_FTP for Windows, Netscape, etc.) - Date and time you tried to connect - Host name or IP address from which you connected - The commands you issued Note that some older clients have trouble with some of the multiline responses that WUFTPD use. You might try putting a "-" as the first character of the password (i.e., your email address) to turn this off. If anyone has trouble logging into the FTP server, try this first!

True for existing ATV, but suppose, for the sake of argument, that an intrepid ATVer decided to dump NTSC and instead use highly-compressed digital video at say 64 or 128 kbps... if it can be done using ISDN, why not packet? At that rate, you could get a decent amount of processing gain even if you confined it to a 6 MHz segment like ATV uses now. And think of the advantages: interference resistance (NTSC has zilch), the possibility of having multiple simultaneous users, internetworking via the Internet or other wireline means, multiplexing with other data, etc. This would be far better use of a prime piece of spectrum than NTSC, n'est-ce pas?

Yes, I think digital SS video is the way to go. MPEG takes about 1.5 MBits/sec AFAIK for "VHS-quality" video. Does anybody know of any relatively cheap ways to compress video to lower bit rates? You mentioned ISDN - I'm not aware of 64 kbps video over ISDN products, but if any exist, they would be worth looking into. Obviously, once it's digital, making it SS would be relatively easy. Does anybody have any info on existing products that could be used for this? My ultimate goal, of course, is digital SS video at the same screen size & resolution as analog ATV. 73 de Will KB9JTT From ATVQ@aol.com Sun Feb 11 23:50:54 1996 Received: from emout09.mail.aol.com (emout09.mx.aol.com [198.81.11.24]) by tapr.org (8.7.3/8.7.2) with SMTP id XAA21173 for ; Sun, 11 Feb 1996 23:50:52 -0600 (CST) From: ATVQ@aol.com Received: by emout09.mail.aol.com (8.6.12/8.6.12) id AAA04621 for ss@tapr.org; Mon, 12 Feb 1996 00:50:21 -0500 Date: Mon, 12 Feb 1996 00:50:21 -0500 Message-ID: <960212005020_219890396@emout09.mail.aol.com> To: ss@tapr.org Subject: Re: [SS:78] Digital SS Video THE LOWEST MPEG rate know of that will give full motion video & color is about 1.2 mbyte/sec. In digital video storage the bcst boys use 9 gigbytes of hard drive to store 70 minutes. that is using a "secret" bit reduction scheme and mpeg. You can get twice that by dropping one field, below that the video gets rather ratty, more like 6 hr vhs copied to 6 hr vhs. The "grand alliance" uses mpeg plus 16, 32 or 64 carriers to make a "constellation" of phase/amplitude modulated signals in VSB format to fit 5.5 MHz of data into 6 MHz of spectrum (go figure, since the full NTSC signal fits there just fine!) That is with multi frame look-ahead/behind fill and vector descriptions rather than actual bit stream. Ma Bell says they can get it down a twisted pair up to 2 miles, but they are using highly EQ'd line and a very low bit rate on multiple carriers and the video is real crap "VHS quality" more like 6th generation VHS from what I have seen so far. But Ma bell is going fiber as fas as she can to add not only video but other services direct to door. I have yet to see any digital system that takes less room than an analog where both offer the same quality video. But hey, microsoft will join with IBM and Intel and do it sooner or later.... for more $$ than I have!. 73 Henry KB9FO From srbible@mindport.net Mon Feb 12 06:47:54 1996 Received: from polaris.mindport.net (root@polaris.mindport.net [205.219.167.2]) by tapr.org (8.7.3/8.7.2) with SMTP id GAA09511 for ; Mon, 12 Feb 1996 06:47:53 -0600 (CST) Received: from polaris.mindport.net (synapse-05.mindport.net [205.219.167.24]) by polaris.mindport.net (8.6.12/8.6.12) with SMTP id HAA03387 for ; Mon, 12 Feb 1996 07:47:52 -0500 Date: Mon, 12 Feb 1996 07:47:52 -0500 Posted-Date: Mon, 12 Feb 1996 07:47:52 -0500 Message-Id: <199602121247.HAA03387@polaris.mindport.net> X-Sender: srbible@mail.mindport.net X-Mailer: Windows Eudora Version 1.4.4 Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" To: ss@tapr.org From: srbible@mindport.net (Steven R.

As always, >comments welcome... Yes, I just read this review this weekend. The items they tested were only PC Card (aka PCMCIA) capable adapters along with their respective access points. The review has a good overview of wireless (now sometimes called Cordless) LAN technology. However, PC Magazine does not have a clue as what spread spectrum is :-). I think the next thing you can take away from this reveiw is the cost of the adapters and access points. Prices are coming down, however, they are not amateur prices yet. Plus the software supplied with the units supports various LAN protocols. Ofcourse this is not a problem if one keeps the units in Part 15 or lives in a land that does not require AX.25. I also typed in the products and manufactures into a web page and included their home web page if they had one. These are the products reviewed in the PC Magazine article. You can take a look (temporary) at: http://www.mindport.net/~srbible/wireless.html Perhaps Barry you can find something of use for your page. 73, - Steve, N7HPR srbible@mindport.net n7hpr@amsat.org n7hpr@tapr.org From cbuttsch@slonet.org Mon Feb 12 12:37:20 1996 Received: from biggulp.callamer.com (cbuttsch@biggulp.callamer.com [199.74.141.2]) by tapr.org (8.7.3/8.7.3/1.8) with SMTP id MAA26409; Mon, 12 Feb 1996 12:37:15 -0600 (CST) Received: (from cbuttsch@localhost) by biggulp.callamer.com (8.6.12/8.6.9-callamer-rdw080995) id KAA19694; Mon, 12 Feb 1996 10:35:56 -0800 Date: Mon, 12 Feb 1996 10:35:56 -0800 (PST) From: Clifford Buttschardt To: Johan Forrer cc: hfsig@tapr.org, ss@tapr.org Subject: Re: [HFSIG:872] Re: SLOW BPSK NEWS In-Reply-To: <24F41D42498@frl.orst.edu> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Hi Johan. Many thanks for your encouragement regarding the slow speed BPSK that we both are doing. I was most interested to see where your are using 30 bps ASCII! Since I had no clue, it is refreshing to know this. We are using ten bps ASCII also with seven data bits and two stop bits. This produces one character persecond. The software is entirely done, and in fact improved daily. We started out with 12 samples per bit and now are up to 20----the maximum that a 486 computer can analyze real time. The system is about to be changed to what is called PSKL which stands for Phase Shift Keying Lattice code. Where the 7 bit code and a two to the seventh or 128 possible pattern, PSKL proposes to transmit a 16 bit frame for each character instead of ten. Here is where things differ from anything normal. 128 characters have to be selected. Finally Bill DeCarle came up with 128 codewords that differ from each other by at least six bit positions!! After all this is done then the computer selects the one character that has the smallest number of altered bits. Now before I scare everyone off with all this, realize that the work done so far is ORDINARY ASCII----just as you are using. The PSKL is simply something we are doing for future evaluation. Maybe now it becomes more apparent why I have no patience fooling around with a silly bulletin board system that will not work for me!!

BACKGROUND AND STATEMENT OF INTEREST TAPR is a non-profit (501(c)(3)) scientific and educational organization with more than 2,500 members worldwide. It is chartered to engage in three principal activities: scientific testing and research into the development and improvement of technological systems for use in the amateur radio service including, but not limited to, digital packet radio communications; research and testing of systems, hardware, and software for packet radio local area networks and computer network systems; and disseminating to the public the information obtained as a result of such research and testing. TAPR was founded in 1982 as a national organization with interests in the areas of packet and digital communications. It grew out of a 1981 effort to design a packet radio Terminal Node Controller, or "TNC," that would be available to amateurs at a modest cost. From these initial designs emerged what is now the de facto standard in amateur and many commercial packet radio operations. Today, TAPR continues as an international, membership-supported research and development organization for the amateur radio community. TAPR continues to develop new communications technology, provide kits for the amateur community, and promote the advancement of the amateur art through publications, meetings, and communications standards. TAPR also maintains a web site (http://www.tapr.org), which includes a page specifically addressing current amateur spread spectrum issues (http://www.tapr.org/ss). DISCUSSION TAPR generally supports the recommendations made by the ARRL in its Petition. Spread Spectrum ("SS") technology has not made great advances in the amateur radio service since it was first permitted in 1985, in part due to the fact that, by today's standards, the Part 97 regulations on amateur spread spectrum are extremely restrictive. In particular, the small number of fixed spreading codes permitted under Section 97.311(d)(1) inhibits the use and development of SS by amateur radio stations. TAPR believes that it is in the public interest, and in the interest of the amateur radio service, to change the rules for SS in order to accelerate the adoption of SS by the general amateur community. TAPR also supports many of the specific recommendations made by the ARRL. First, TAPR supports the ARRL's request to modify Part 97.311(b) as it pertains to the unintentional triggering of repeater inputs. This section is redundant with other parts of the Commission's rules and, therefore, is unnecessary. Second, TAPR supports the ARRL's request to delete sections 97.311(c) and (d), in order to permit SS emissions and spreading codes that are not currently authorized. Elimination of the rule that dictates specific spreading codes is necessary to facilitate further experimentation and to match the provisions allowed under an existing amateur service SS STA, discussed below. In addition, it would facilitate the use and adoption by amateur radio operators of Part 15 SS equipment and hardware. Third, TAPR supports the ARRL's proposed change to 97.311(g), which would provide for automatic transmitter power control to limit the output power of an SS station to that which is required for communication, when more than one watt of output power is used. TAPR, however, differs with the ARRL as to just how simple this requirement would be to implement technically. While TAPR agrees that technically it is simple to control the output power of a transmitter, it is quite another matter to make this control automatic and foolproof. If the Commission decides to proceed with this particular change to the rules, it should phase the change in over some reasonable period of time, in order to give the amateur community the opportunity to develop and deploy SS equipment that properly can meet this requirement. While, as noted above, TAPR agrees with many of the ARRL's recommendations, it disagrees with a few of the proposals contained in the Petition. In particular, TAPR differs with the ARRL with respect to the question of which frequencies should be authorized for SS emissions. In the Petition, the ARRL proposes that brief test transmissions of SS emissions be permitted only on those frequency bands in which SS emissions currently are authorized. TAPR believes that SS emissions should be allowed on all frequency bands covered by the SS STA currently held by Mr. Robert Buaas K6KGS (6m and 2m, in addition to the frequency bands currently authorized by Part 97). In addition, the Commission should allow SS emissions in the 219-210 MHz band, which was authorized for use by the amateur radio service after the Buaas SS STA was originally granted in 1992. Finally, the Commission should not impose any restriction on the length of time SS emissions are transmitted. Ample time already has been provided for the experimental phase of SS usage in the amateur service (five years of experimentation under the 1980 AMRAD STA and ten years under the current Part 97 rules), and it is now time to allow SS use without restriction. TAPR also differs with the ARRL as to how station identification and documentation should be handled under a revised set of rules. The ARRL in its petition did not ask the Commission to delete sections 97.311(e) and 97.119(b)(5) of the rules, even though it questioned the practicality of the requirements set forth in these sections. TAPR, in contrast, recommends that the Commission delete these subsections of the rules. The interference and harm to the band in which an SS station is operating that would be caused by a requirement to use a CW identification outweighs the benefits that would accrue for monitoring purposes from the use of the ID. As a result, the amateur radio community should be permitted to develop an approach for handling the necessary functions of monitoring and identification. TAPR already is working on possible resolutions to this problem and in the near future will be in a position to make a proposal to the Commission on this matter. CONCLUSION SS technology can provide many useful benefits to the amateur radio community if its use becomes more widespread and mainstream. In order to accomplish this, however, certain changes must be made to the Commission's rules governing the use of SS in the amateur radio service. By making these changes, the Commission will create a regulatory environment that will give members of the amateur radio service enough flexibility to develop innovative equipment and hardware employing SS technology. For these reasons, TAPR urges the Commission promptly to issue a notice of proposed rule making to facilitate spread spectrum communications in the amateur radio service, as proposed in the Petition and as modified herein.
