If you support the work that TAPR is doing, we would welcome your membership of the organisation. You can join by clicking on http://www.tapr.org/tapr/html/orgf.html . We have also been listening to members requesting that we support electronic commerce. TAPR are currently testing the use of PayPal in association with the current ordering system on the Web. We will post a message on the WWW site as soon as this is available. Until then you can still join. Just fill out the electronic form as normal, and state in the comments that you want to pay with PayPal when it is available. Digital Communications Conference This years DCC will take place at the Hartford/Windsor Marriott Airport Hotel in Windsor, Connecticut, on the weekend of September 19-21, 2003. The hotel is 6 miles south of Bradley International Airport (BDL) and 13 miles north of ARRL Headquarters in Newington. Information will soon be available on http://www.tapr.org/tapr/html/conff.html. Until then you can find more information in the PSR at ftp://ftp.tapr.org/psr/Winter_86_2003.pdf We will soon be issueing a call for papers for this event. Have a think about what you want to write about and start planning your paper now. If you are unable to come up with a subject, it is often possible to find friends with something to write about, but who don't have the time. You can help your friend and the Ham community by writing the paper on their behalf. There will be two popular discussion points at the conference - Software Defined Radios and 802.11 networks. DCC Conference Proceedings We have also reduced the price of each of the proceedings of the DCC up until 1997 to only US$6 each. This makes the a real bargain. We are also making available sets of volume 1-10 and 11-16 available for $US$33 each - but please bear in mind that we no longer have copies of a number of the proceedings so we cannot guarenttee that the sets will be complete. Electronic Distribution of Packet Status Register (PSR) Magazine Listening to members we have found that many people are concerned about missing out on the PSR now that it has gone electronic. We recognise this as an issue, and we have come up with a solution to make things a bit easier in this digital age. We have created two mailing lists to assist you with keeping up to date with the quarterly magazine. They are PSR-Announce PSR-PDF PSR-Announce is designed to advise the availability of the PDF file for download. We recognise that many people are on slow internet connections at home, or in fact have to pay for their bandwidth. So we have created a mailing list just to tell you when the magazine comes out, and to let you know how to get it. You can subscribe by visiting http://www.tapr.org/cgi-bin/lyris.pl?enter=psr-announce&text_mode=0 PSR-PDF is designed for people who have a faster internet connection, or who know that they will never get to read it unless it is sent directly to them. Since PSR often contains graphics, the file can be over one mByte. You can subscribe by clicking http://www.tapr.org/cgi-bin/lyris.pl?enter=psr-pdf&text_mode=0 802.11 Mailing List Whilst we are on the subject of mailing list, TAPR have started a mailing list for 802.11 'Wireless Internet' operations. It seems that every community has a mailing list dedicated to 802.11. So how is the TAPR one different? It is dedicated to 802.11 use in ham radio. The list contains active members of the entire range of technical ability - from the most basic understanding of how radio works, to the deep internals of this equipment. Such a broad range that everyone is sure to fit in. You can join by visting http://www.tapr.org/cgi-bin/lyris.pl?enter=ham-80211&text_mode=0 GNUradio receives HDTV Matt Etus and the other people at the GNUradio project have announced that they have managed to decode the HDTV data stream on their PC's and have published the source code online. This is an amazing feat by Matt and the team. They are not quite to the stage of real time HDTV decoding on a PC, but are close. Write for PSR!!! PSR needs articles, and we would love to publish lots more in the PSR magazine. PSR is a great place to publish articles on everything from local operating practices to deep technical papers. And since the last issue TAPR is now rewarding those people who are helping others by writing articles for the magazine. Following the last issue, six people had their memberships extended by three months. This is just a small thank you from us at TAPR to those people who help us out. More details on PSR can be found on www.tapr.org Conclusion I hope you have found this document informative and useful. TAPR is always looking for new things to do and how to improve what it is already doing.

If you have maximum signal you can get 11 Mbps. As the signal drops off the speed will go down to 5.5 Mbps. Finally, it will go down to 1 Mbps, etc. Also, keep in mind that there is a good bit of overhead with 802.11b, so the maximum actual throughput is about 9 Mbps. Couple this with the fact that 802.11b is half-duplex and you are down to about 4 Mbps actual throughput. However, given the short distances involved, I suspect you have some cable loss or a bad connector(s) in the systems somewhere.

Hmm, always this magic 1/2 figure seems to get thrown around when considering a half duplex link. What is data is flowing in mostly one direction (with only short ACKs in the other direction)? Then more than 50% of the channel's time could be spent actually transferring data. As a case in point, I have _measured_ throughput between two well sited (i.e. next to each other) machines running 802.11b and got around 600 kB/sec (or close to 5 Mbps). Others in our wireless group have managed even higher on good paths. I usually test by using a throughput measuring tool, or a plain old FTP transfer.

You need to deal with clock, frequency, and distance uncertainties. On top of that you disquise your signal within noise and you need to be careful in terms of extracting it. You need a good quality channel and feedback loops to overcome the uncertainties mentioned above. >>By this >>I mean a DSSS signal in, mixed with an IF frequency and then >>out as >>another frequency. Can this be done? You always have to upconvert your signal. You cannot trasmit baseband if that's what you're asking. There is a lot of theory behind this but, the stages are: 1) Spread your signal (DSSS) this will increase your basebandwidth... 2) Modulate it (FSK-ASK-PSK or whatever suits your channel) 3) Upconvert and there you go!!! What will you send? Voice? Data chunks? What's the freq you intend to transmit? You need to examine your limitations.. You cannot always do as you wish. Have a look at www.rfcafe.com Start by considering the type of data you wish to send and the freq you want to transmit, and you can find out what length of code you'll use and the best modulation technique.

By this > I mean a DSSS signal in, mixed with an IF frequency and then out as > another frequency. Can this be done? You mean mixed with an LO frequency. No problem at all. Inside most DSSS equipment the modulated signal goes through at least one frequency translation before transmission, and another one on reception. I assure you no tricks are required. DSSS will go through satellite transponders, TV-type transposers and transverters just like any other modulation. If there is any problem, it's the need for wide bandwidth to pass the wanted signal. That leaves a transponder open as a barn-door to unwanted narrowband signals that could saturate the system. For this to be an issue the DSSS system would need serious amounts of coding gain to be capable of rejecting such interferers in the passband. In this situation you could also end up with more noise power being amplified by the transponder than wanted signal; unlike a DSSS receiver a basic transponder can't separate them. To fix this situation a code-domain filtering process would be needed; ie downconversion, correlation, synchronisation & all that.

I haven't had good luck with LYNX. There "problem" of the "Proximity effect" is BS. The real problem is lack of a buffer stage for the oscillator. Last time I looked, their transmitter is just one stage, the oscillator. That is poor practice, esp with a SAW oscillator. Too much loading on the circuit "pulls" it off frequency, and thence out of oscillation. A SAW oscillator is an LC oscillator that is frequency set by the SAW device in the feedback loop. The LC oscillator must be within 5% of frequency for the thing to work. If you are in the need I have a circuit that works just fine. > > What do I have to do to get FCC approval on the modification > Absolutely. Global Engineering Ltd in E. Haddam CT offers the best price I have seen. (No I don't get any $$ for this plug) TUV is the most expensive. > Also, what do I need to do if I also want to change the antenna. > In the States, the rules have nothing to do with power output for non-ss equip. They have to do with radiated field strength in the peak of the antenna beam. So a "gain" antenna forces you to use less transmit power. The power limit here is very close to an equivalent of running 3/4 mW into a isotropic radiator. If you run about one Mw into a quarterwave wire attached to your board, you will be darn close to the maximum radiated field strength in the peak of an omnidirectional beam. Probably two or three dB or so low, not about 6 dB high as you might expect. The difference is due to the poor ground plane (the circuit board, etc.) under the antenna element. Now, it is difficult to have only one Mw output with a two stage SAW based transmitter (see above for the reason for two stages. Read it again), so why do you want another antenna? Yes, it makes a lot of sense everywhere but in the US and Canada. Also, here your circuit must protect against someone changing the antenna. I have read that the use of reverse SMA connectors is no longer accecptable by our FCC. The low cost solution is to solder a wire into the circuit, and adjust the transmit power accordingly. To answer your question, every time you use another antenna, you have do retest and refile. You can download our rules from FCC.gov Go to the office of engineering technology (OIT) & follow the links. Jim Ussailis, W1EQO / VE1EQO jim@nationalwireless.com > And one last question..

I had one made once in 3.16 inch diameter circular guide for 2.8 GHz. There the fellow arranged several sheets in a symmetrical fashion on a plug at the end of the waveguide. Following that idea, I would put a carbon taper load in the back end of your ridge guide. Fabricating the load to a very fine point is very important for a good match.

A Message from N.E.Mastorakis

Dear WSEAS Members and Friends,

We are glad to announce you the organization of the following conferences.
You are invited to submit a paper or to organize a special session.
I will personally supervise the 2003 WSEAS conferences (see the list below)
and WSEAS Chairmen and Organizers can guarantee their success.

Please note that:
1) The multiconference in Corfu island will take place in the marvellous 5-Star
Corfu Holiday Palace (former Hilton of Corfu). The manager of the hotel gave us
extremely low prices for your accomodation.
The multiconference (it is in its 7th year) will host approximately 500-600 papers.

2) For the multiconference in Athens (Neural,Fuzzy, Evolut.Comp.),
all the accepted papers will be published in a Special Issue of WSEAS Transactions
that will be sent to the authors after the conference.


3) Also the WSEAS web multiconference offers to you many advantages like
remote presentation, low cost, etc... as well as the publication of your paper in the proceedings (and journals after selection)


Best Regards

Prof. Nikos E. Mastorakis, President of WSEAS,
WSEAS
Ag. Ioannou Theologou 17-23,
