Wow. That's a real bummer. I'll have to crack my knuckles and figure out how to get the ball rolling again like I did for my club that was about as dead as the old folks walking in. Rough thing to say, but that's the way it was. For one reason or another, a lot of folks were sitting in front of the TV instead of the radio or work bench, and even though this is only my second post, the idiot box is the main problem. I don't know what it is now because I joined the Army and now deployed to the stinky country of Iraq. If you spend more time in front of the TV than you do the work bench, I think you may want to disassemble the problem, or reallocate the asset for something useful. I've been working on a project, just a draft right now, but will be manifesting into the real deal in a little while. I would like to know everyone experiences with different multi-level modulations like QPSK, 8-PSK and the others that are being used. I like the QPSK or 8-PSK as that is what we use for our satellite internet. What I'm working on is a TCP/IP setup that will have the functionality of a wireless router, but will have the functions amateurs like to see, and also be open source Linux so we can attract more computer people in here. Seeing how this a group with people who are computer oriented, there shouldn't be anyone griping "this is ham radio!" If you are one of them, then pay no mind as I pass you by. If you are familiar with DD-WRT, it may have that setup as I like using that on my linksys and Motorola WRTs. the main thing I like about this idea is that it will NOT require drivers on a computer to work so an old Toshiba Satellite 75MHz Laptop with an PCMCIA Ethernet port and TCP/IP support with Win3.1 will work. ~Benjamin, KB9LFZ ________________________________ From: ham-80211-bounces at lists.tapr.org on behalf of Bob Keyes Sent: Mon 28-Jan-08 22:30 To: TAPR Mailing List for Ham Radio Use of 802.11 Subject: Re: [Ham-80211] Activity - what is the data world doing?

I know the bands are virtually empty except for a brief period around rush hour but most that territory has been claimed. The 220 band is almost completely vacant except for empty repeaters and we have a megahertz or so around to 19 specifically for data transmission (channelized, 100 kHz wide channels). ---eric -- Speech-recognition in use.

Geosynchronous satellites have a higher RTT, which affects the applicability of short packets with acknowledgements. LEO satellites will have less delay, but may be harder to track, and when they approach horizons of course will suffer distortion due to more atmosphere to penetrate. > Experiences are one thing, actual parts availability and > bang-for-the-buck might be different.

There's much happening with regards to the AR5K driver in Linux. There's a move from the 'closed' HAL, provided by Atheros, towards the reverse-engineered OpenHal and its relatives in the BSD and Linux worlds. There is also much legal uncertainty here, as the US Gov't. requires that spreading codes are standardized for DSSS, though I am not sure what restrictions are in place for OFDM. > Historically, 64QAM was what the telephone company settled on as the > best compromise for long distance microwave hops.

I think that anything that is not open-source (be it BSD or GPL) is not ham radio. We have no use for proprietary schemes and they should not be tolerated or even allowed. Considering this, we should try to move as much Amateur Radio activity towards FOSS as possible (too much of it is Microsoft centric, and this is a real problem for me). > > If you are familiar with DD-WRT, it may have that setup as I like > > using that on my linksys and Motorola WRTs. I prefer OpenWRT which is why I develop under it. I believe it has a greater future than DD-WRT because of its OS redesign from the ground up. I don't fault you on a philsophical level for using DD-WRT though. > That (and its cousins in the open and mostly-open source community) is a > good start.

Eh, I've got a big stack of such old laptops (I actually just chucked anything that was less than 90 Mhz!) and I'd like to find uses for them - but these can be on HF with less demanding protocols. > That's a good start. But it has to be cheap, too. Cheap is crucial. But how cheap? There should be a sliding scale of expense that translates to performance. I'd like to think that with a lot of elbow-grease and $50, a station can be assembled which will share some compatibility with thousand dollar stations. The reason for this is both from idea that some people may not have as great an interest or need to have powerful stations, to those people who do not have the economic means to afford more expensive hardware. What bothers me right now, is the separation of the open-source Community Wifi movement and that of Amateur Radio. There is a an amazing amount of enthusiasm and energy in the former, but experience and resources in the latter. At my club (Harvard Wireless Club - world's oldest station!), the emphasis has been for some years on HF and contest operation. Tese are good folks, but the number of undergraduates involved in the club in reaching dangerously low levels. I am told that other clubs are in serious danger, and we may lose them entirely unless their decline can be stopped. I believe this can only happen by amateurs seeking out and adopting the new generation of digital hams. I don't want this to be interpreted as saying I want to ban AM & SSB on HF, but I believe that digital radio shoudl be acknowledged as the future of amateur radio and awarded spectrum as such. But digital hams must make sure that our DSPs can detect analog modes and operate with the minimal amount of interferences as possible. I think we can do this. CPU power and DSP methods, along with speech recognition, are growing by leaps and bounds. But such CPU power does not come cheap, which is why we continue to need bands which are digital-only, for those stations which are less sophisticated (because they need to be cheap). I know I am going on at some length here, please forgive me, as I have had too much coffee. I believe that Amateur Radio must continue to justify its existance and its allocations in light of the vast demand and monetary value of bandwidth (even though, per radio act of 1934, bandwidth is not to be sold!). We must do this in a non-competition basis with commercial providers, especially as those providers are paying more and more for spectrum. Greedy governments will be increasingly casting eyes on underused amateur spectrum in search of money. We must prove that the spectrum is being used, and is being used wisely. This will involve some rather introspection by the amateur radio community. These philsopical arguements can go hand-in-hand with those in the FOSS (Free Open SOurce Software) community. For instance, is it appropriate for a commercial entity to utilize amateur radio spectrum when the information they transmit is freely available to others without charge? How useful to the public does this information have to be in order to to be a legitimate use of the spectrum? I have thought of this issue in relation to sensor networks. I believe that meteorological information and climatological sensor information is a legitimately public use of the amateur spectrum. I have done some preliminary design of some possibly radical changes to sensor networks, as a result of my involvement with sensor networks projects at Harvard (CitySense.Net - though I am no longer employed by them). But what about other information? If I were to say, put a sensor on amateur spectrum which provided information on the water level of a certain reservoir, would this not be more appropriate for a commercial or municipal license? Or what about atmospheric carbon dioxide levels downstream from a coal-powered utility plant, which would be primarily for the use of the owners of that plant in proving their compliance with various regulatory reuirements? But as it could also be used by their critics, and atmospheric researchers in general, is it still legitimate, even though it is "boring" to the rest of the amateur radio community? Perhaps these issues can be addressed by considering how much of the valuable spectrum they consume, and what benefit they produce - but do we want to make every sensor transponder open to the bureaucracy and competitive sniping that such policies might entail? If fashioned correctly, a new policy might not only protect amateur spectrum, but to increase it. For instance, I would think that an automated digital NVIS system would be of great pragmatic value, while also allowing amateur use and maintenance. Lastly, I would like to find a way of FUNDING such research an implementation of this infrastructure which may be useful to both amateur and scientific use. Consider the advantage of volume-produced digital NVIS gear, for instance. Of course, as a researcher in digital radio communications, I;d like to think of some of that funding paying my rent and an occasional conference, be it formal or a beer-gathering with friends. 73, Bob Keyes N1YRK
