Chuck AA5J Rick W wrote: Hi Stelios, The reason you may not have heard from others with their difficulties with Linux, is that they there are few who have even tried and those who have may not talk about it. I take the middle path, where I see the value of both OS's, but the value of Microsoft is still very large, at least here in the U.S. As Andy can tell you, I had a lot of trouble for several years with Linux not able to run my 22 Samsung SyncMaster 225BW, particularly with my higher end AMD/Nvidia HP computer. I have been able to run openSolaris from a live disk, not that I would plan to move toward that OS, HI. They always tell you to make sure that you try the live disk so everything can be checked out to work properly. Then when it does not, they tell you to install the OS and do the various configurations, downloads of software, etc. to get it to work. Most people have no interest in doing that and never will. I have spent many, many hundreds of hours with Linux, partly because I was going to figure this out and get it to work. It has been quite expensive compared with Microsoft products because of books and some commercial software that I have bought to try and get a better understanding. But after considerable interfacing with support groups and even to the point of getting a commercial product sent to me from the company, I could not match Microsoft. I eventually realized that if techy types like me are having this much trouble, it just is not going to go anywhere with average users, and that includes ham users too, if they can't get something to work well. Not just getting by, but with good usability. More recently I have tried live disks of Mandriva One 2009, Ubuntu 8-10, openSUSE, fedora 10,and others and found that although I could get the resolution correct for the monitor from some (not all), on my lower end emachines computer (2.4 GHz/512 Meg RAM), the font rendering of all Linux that I have seen thus far is inferior to WinXP and Vista. And I have also found that Vista is better than WinXP. Some will outright deny it, but I have had some agree that, yes Linux is not quite as good with font rendering, but that doesn't bother them because they want the freedom from MS, etc. I don't have any problem with MS at all as long as the product works well and supports what I am doing with computers. I have a brother who is an administrator for a well known University system and he runs many Linux and MS servers and has no problem with either. When I mention the desktop, he laughs and says that he would never use Linux for that, although he might use Apple Mac OSX. For me, (not others perhaps, but for me), if I switch to another OS, there has to be a reason other than I hate someone. It just has to work as well as what I am currently using and have additional advantages. Linux may have advantages in terms of viruses and malware, however a prudent person will still run security software on any system. But most all the programs that people like to use on Linux, which are generally free as in beer and free as in speech, are also available on Microsoft OS's too. For casual users who need mostly the web and an office suite, they could use Firefox and Open Office on either platform. For those who have specialty interests, especially ham radio, then MS has the edge since the best ham software is often only available on Microsoft OS's. Sometimes the only software. Since Microsoft OS's are typically pre-installed on computers here in the U.S., I don't see any change coming soon where you would buy a computer without an OS. Even the eeePC which Linux had a lock on the market for many months, is now mostly MS. If it can not beat MS on that platform, when will it? I see Linux gaining momentum in developing nations and since they make up the majority of the world's population, that has to eventually cause the tide to shift toward Linux. But that could be a decade or two away here in the U.S? For PSKmail, my expectation is that you need a sort of critical mass of users. That can not happen here without running the client on Microsoft OS's. Even then there are competing systems depending upon what you want for capabilities. Even for those who are Linux averse, it is not unreasonable that someone who wants to run a server could get that to work. I know that I could do it, as at one time I had fldigi running under Linux. (It did take quite a bit of effort and tremendous help from Dave, W1HKJ who is simply outstanding with his support). One area that you mention with the use of ARM based computing, or other low cost, low power systems, has to be the strongest value of Linux at this time. It can scale up or down as needed and Microsoft can not match it on the low end. It will

Re: [digitalradio] SignaLink USB Interface Reviewed in Popular Communiations, September 2008
Mark Thompson wrote: http://www.popular-communications.com/PC%20Highlights%20Sept%2008.html TECH SHOWCASE The SignaLink USB Interface—A Plug-And-Play Solution For Digital Communications Modes by John Kasupski, KC2HMZ Anyone who has experimented with receiving digital format signals by radio has undoubtedly experienced one or more of the difficulties that typically arise when you set out to decode digital signals using a radio and computer. Your sound card is incompatible with your software, or you don’t want it tied up doing digital decoding. You have more than one radio you want to use and don’t want to have to buy or build separate interfaces for each. Or perhaps you just don’t want to pay a fortune for all the software you need in order to decode the numerous digital modes that exist (with new ones seemingly being invented daily). If this is the situation you’ve found yourself in, you’ll find this article to be just what the doctor ordered. Earlier this year, I purchased a SignaLink USB interface (Photo A) from Tigertronics in Grants Pass, Oregon. This device, which costs less than some of the competing commercially available radio/computer interfaces ($104.95 if ordered with a cable to fit Kenwood and ICOM radios using a 13-pin DIN accessory port; $99.95 for everybody else), not only interfaces your computer to any radio, it also contains its own built-in USB sound card. That means that the sound card already in your computer is left free for whatever else you want to do with it. How It Works And What You Get The SignaLink USB connects to your computer’s USB port and is powered from the USB port so that no external power source is needed. All the necessary cables come with the device, including the USB cable, the cable to interface the SignaLink USB to your radio, and a mono cable to connect to radios that don’t have receive audio on the mic or accessory jack. Additional cables can be ordered if you have more than one radio and they don’t use the same cable. The mono cable can be used to connect the SignaLink USB to an external speaker jack on a scanner or shortwave receiver, or if using a transceiver, the connection is made using the radio cable. This can be accomplished using a connection to a 4-pin round, 8-pin round, RJ-11, or RJ-45 mic connector, or you may instead order the radio cable to connect to a data or accessory port that uses a 5-pin DIN, 8-pin DIN, 13-pin DIN, or 6-pin mini-DIN connector. An un-terminated cable for radios that use a different type of connector is also available in case you have an unusual situation, such as wanting to build a cable for a handheld radio. Also included with the device is a set of jumper wires that simply push into a socket on the SignaLink USB’s circuit board. A software CD is also included with the device and contains jumper settings for the most popular radios. Settings for other radios can be determined by following the procedure in the included manual, or by contacting the Tigertronics tech support staff.

Re: [digitalradio] Re: RFSM 8000
dmitry_d2d wrote: 1. A few words about OFDM and serial tone modem. Let's find out how the fight between ISI and Doppler shift takes place in these systems. OFDM uses the great number of low speed channels so the symbol duration increases. While the duration of ISI is much smaller than symbol duration everything goes well. Consequently there is an aim to increase the number of channels ad infinitum BUT at the same time natural limitation takes place. It's just a Doppler shift effect. Hence there is always a compromise between ISI and Doppler shift. Moreover we should take into consideration a big peak factor which results in non-effective usage of power of transceiver. There are methods directed at improvement of peak-factor, but the most part of them makes the system characteristics worse. In case of serial tone modulation the fight ISI with Doppler is provided with adaptive algorithms. The more effective and faster they are the larger number of Doppler and ISI the modem can manage. As for RFSM it should be mentioned that now it includes rather efficient adaptive algorithms that work properly at a speed of 600(500) up to 4800(4000) bps (wide/narrow mode). To work at a speed 6400(5333) - 8000() much more compound algorithms are needed. In particular using turbo-equalization will improve noise proof feature at all rates. Therefore OFDM and serial tone modem can be more efficient in dependence on channel statement. In my opinion serial tone modem with effective adaptive algorithms is the most effective. We'd like to mention that under certain circumstances either serial tone or OFDM modem can fail to provide connection, for example, when the Doppler shift is extremely high (polar communications). In that case one should use the methods of spectrum spread that extending the symbol in time and frequency. Unfortunately the speed would not be high in this case. So the best way out is to measure the channel characteristics and choose the speed of transmission and modulation method according to them. The full adaptation of the all characteristics is required. 2. About our users. The project RFSM-2400/8000 was initially aimed at organizations (not for HAMs)! (First version had no 0,3-2,7 band, which is adapted for HAMs). Its prime value is that high-performance algorithm is used in it. Consequently only technical specialists of organizations where data (files, mail etc.) transmission through HF is needed can estimate the program at its true worth. They need the following: high speed of connection and data transmission. They are the FIRS GROUP OF OUR USERS. For example there are organizations (our users at the moment) who even haven't looked upon HAM -modems (little speed, instability, absence of files transmission in spite of excellent chat-exchange). If you are interested in RFSM as in a program for chat- exchange (or even for file transmitting but you do not need a high speed) and runner is not important for you:. You are the SECOND GROUP OF OUR USERS. $60 may be a pretty penny for this product for you. There is also not numerous GROUP OF USERS - THE THIRD ONE The representatives of this group are specialists in HF- radiocommunications and radioamateurs at the same time who is interested in algorithms of a high efficiency - the runner of the program. May be $60 is rather expensive for them but they can trial versions for free. They communicate with us suggesting interesting and moreover useful ideas. We really appreciate their advices and suggestions. Due to the THIRD GROUP the first version of RFSM has transformed in the product adopted for HAM. 3 . There are several remarks on the open source codes. a) RFSM-2400 (and all the more RFSM-8000) is not just a dumb modem though such a rate is also possible (it was used in PSKMail). Our product is an accomplished system of communication that provides different types of services including receiving/transmitting e-mail on Internet. b) Speaking about OFDM it should be pointed out that we have got experience in such a kind of modulation and can remark that to construct this modem is incommensurably easier than Serial Tone Modem. But the modem of this kind doesn't compare with RFSM characteristics. If we were not be able to realize Mil-STD correctly and use OFDM in RFSM, we would not be sorry to distribute source codes. c) Philosophy. Professional free software is possible because qualified developer has been grown up by certain company. The buyers have already paid for software and progressive developer as well. Then at the same time free software appears (like RFSM-2400) - like an ad, to create an image or ease consumers' tasks. The fact that software is free is a result of successful sales of developer.

Yes. Thank you for your very welcome explanation. I guess someone has to stir the pot, but I was having fun in my ignorance and bliss. I don't really want anyone to clarify that I can not do something that I have been doing, just because someone else did not understand the rules. The people who are at FCC now, well most of them, were not even there when the rules, well most of them, were written, and probably don't understand the English language any better than you and I. So why stir the pot for a specific ruling unless you have some sort of agenda or are on some sort of power trip? Yamamoto said I fear we have waken a sleeping giant after attacking Pearl Harbor. Others have said Let a sleeping dog lie. Many other sayings along those lines, might make one think that Don't stir the pot is also appropriate advice.

Some one has to take action or nothing will change and we will continue to have absurd arguments over each person's individual interpretation. Not a good situation. When you identify a problem in understanding a rule, and clearly there is no question that a number of rules are at issue, and you contact ARRL and ask for understanding, and they consider a rule to be unclear, what else can a reasonable person do than ask those who are the rule interpreters? How could you possibly not agree with that? How could anyone not agree with that other than a person with an extreme agenda? As a long time instructor, I feel that of all people, I should know the answer to most any Part 97 rule since I teach these rules in my classes. If I don't understand it, how can I be expected to explain it to others? It has nothing to do with any power trip. We all know the folks who are involved in that! Remember that even a lawyer can not help in such cases, unless they happen to be the lawyer who is enforcing the rules. That is why you need to find the person where the buck eventually stops and they can make an interpretation. If you don't like their interpretation, you can petition for a change. As a professional consultant involved in environmental safety and health for many years, I did this frequently. You don't just tell your clients that no one really knows. It is not possible to just know the interpretation of every rule as written in a regulation. You simply must contact those who do the interpretation when you are in doubt.

Aw, pshaw. I am sorry that I hurt your delicate sensitivities, Bill. Get over it. All this political and administrative bs has absolutely nothing to do with digitalradio. It is one clique fighting with another clique. One group is asking for clarification about the other group's operation. How is that OK? If you think that I am not allowed to express my opinion, then you prove my point. However, I will not stand by without comment and get wet from your pissing contest. And I will not stand by while less than 0.5 percent of the US amateur radio operators mucks around and potentially screws it up for the other 99.5 percent. It was small groups of activists that got us in the incentive licensing fix, and it was small groups of activists that got us in the separation by bandwidth fix. It will be this small group of activists that makes the next change happen. I just hope the trend doesn't continue to worse and worse and worse.

Very little. It is a fairly broadband 1:1 transformer at HF frequencies and it forces the currents in the center conductor and shield to be equal.

I agree with Joe on this point. Amateur radio has always been self policing. How can we self police the Pactor operators, automatic or manually controlled, when even if we spend the big bucks to acquire a pactor modem, we can not monitor their transmissions? We can not even know whether the operator is even a ham.

I hate to see ham radio being used as an internet email service that in 99% of the case the mail is not related to ham radio. I think that 99% of the ham support handling emergency traffic and would stay clear of any frequency that was being used for such a purpose. A lot of people including hams do not really understand the term emergency traffic. Simply put it means the threat to life, injury. and property. 99.99% of all emergencies are confined to a general local area. It very rare that one needs to send traffic from the west coast to the east coast or Washington DC. Ham radio serves a great purpose in these cases and we as operators should help out when we are needed. But for someone out in his boat just wanting to check is email should not be allowed on the ham bands. My 2 cents worth. Joe W4JSI

As to 20 meters, you are correct that the majority of RTTY appears to be above 14080, but I have heard it as low as 14.074 on non-contest QSOs. Give a contest and people go wild and you hear RTTY as low as 14.010, which is really irritating to a CW op. Most all of the PSK I have worked (128 countries to date) have been on 20 meters, and all of it within the 14.069-14.073 bandwidth. The other digital modes have all been around 14.065 - 14.070. This is the reason I was recommending the lower side of PSK rather than just above it. I havent called CQ on the other modes, above the PSK area, but typically when I have answered others they are below it. Right now, with such poor conditions I am hearing no digital signals at all on 20. I have worked few digital stations (other than RTTY) on 15-10 so dont know how those separate out. Also have not been digitally active on 80 or 40 all that much either. Mostly, I look for DX and those dont afford me new ones very often. The 160 meter band is an exception there, as I figure that new ones should be easier on PSK than SSB or even CW- but so far that has not been the case, for really long distance ops. I just dont think enough people are using the band with PSK or other new digital modes. Your last comment: Perhaps it would not incur the wrath of the FCC if we operated voice and then also transmitted data and fax and image in between voice transmissions, but do it in the voice/image part of the band? would appear to be exactly what we should be doing. It would keep the voice part out of the lower piece of the band and place both it and the images together - and as per my above - is totally legal according to the charts. I was hoping that would be what we would see on the other bands as well, but guess that is still not to be.

Re: [digitalradio] Re: NTS and traffic handling and digital
Greetings, As one who has been inactive in amateur radio emergency communications for several years, I heartily endorse the use of the Winlink system for EMCOMM. The reasons are as follows: Winlink 2000 tries to have 24/7 availability. And mostly succeeds, through the use of Automatic / Semi-Automatic (call it what you will) responders, we are able to connect to the world from anywhere at any time, if we have the capability to connect to the Winlink 2000 network. They have stations that monitor most (all ?) bands that will let us get through under almost all conditions. From my viewpoint, the important thing is communications. If necessary, we can send messages to the control operators theirselves with instructions to connect a particular telephone number, etc. and I AM SURE they will carry out the task to get the emergency message through. I have been inactive in NTS for several years, however in the several emergency situations I have been through, I would have been very happy to have a system equivalent to the Winlink 2000. NTS was typically manned by hams like me, I worked full time. I was not available 247 most of the time. In response to the tornado that ripped through Wichita Falls, Texas, my employer saw fit to let me off for one day to support emergency communications, but for the most part, I was only available for the evening NTS nets. I started the DFW Traffic Net on 146.88 and the Texas Slow speed CW net. Served as one of the DFW representatives to the Texas Traffic net, RN5 Liaison and CAN Liasion. We handled almost exclusively personal message, some 3rd party and some ham to others, except during emergencies. But, when the chips were down, we had the capability to pass message traffic that mattered. Whether we use HF, VHF, UHF, Satellite, or magic, the key ingredient to emergency capabilities is training. Untrained hams are part of the problem. Trained hams are part of the solution. Regards, ChuckM aa5j mailto:[EMAIL PROTECTED] Need a Digital mode QSO?

Re: [digitalradio] Re: Digital TV (off topic)
As a former user of a BUD (big ugly dish) of 10' diameter and analog TV signals, I can say for sure that there is absolutely no comparison with respect to video quality between the broadcast quality (eg., 34 dB SNR) video signal as received by the BUD and those transmitted by typical digital satellite providers such as Dish and DirectTV. The analog signal wins hand over heels. Now that almost all TV is sent digitally, the difference no longer stands out like it did back when. The HDTV signals, however, are much better on either type of display than were the analog broadcast band quality pictures. Except when the signal breaks up, for whatever reason into those gross digital blocks. I have never been a fan of analog cable due to the p-poor quality control. The SNR of most analog signals barely meets minimums at the user's TV set. My 2 cents. 73, Chuck, AA5J At 12:25 PM 1/28/2006, you wrote: I'm with Alan.

Re: [digitalradio] Re: The skinny on software timebombs
Hey guys! We are downwind here. Please stop pissing. :-) Chuck, AA5J At 01:52 PM 10/26/2005, you wrote: AA6YQ comments below --- In digitalradio@yahoogroups.com, DuBose Walt Civ AETC CONS/LGCA [EMAIL PROTECTED] wrote: snip I don't think any amount of signal bandwidth is going to allow telephone-quality voice connectivity between Boston and Sydney on the 10m band over the next couple of years. Ya don't huh Dave? How about the commercial HF DV communications that already do this? Well on 22 MHz, which isn't quite 10M. You made the outlandish claim that SDRs would enable HF communications in the absence of propagation. I cited a 10m path with no propagation as a counter-example. Your response that communication is possible on a path with propagation (your 22 Mhz example) is irrelevant to the discussion, and leaves your original assertion unsubstantiated. SDRs are great, but they're just an implementation strategy. They aren't magic, but they do open a world of new possibilities for amateur experimentation. Given our limited HF frequency allocations, I'd rather we focused our innovation on doing more within the current bandwidth limitations. Amateur experimentation? Where have you been? The commercial folks are falling all over themselves doing this. In fact, there is a U.S. Military Standard that says all new multi-band radios WILL BE SDR. You think that commercial firms and military suppliers have exhausted all possibilities with SDR, eliminating all opportunity for amateur experimentation? Seems unlikely, Walt. ...Given our limited HF frequency allocations, I'd rather we focused our innovation on doing more within the current bandwidth limitations. So what are our current bandwidth limitations...say for data? Part 97 says I can operate a data mode on 40M from 7.000 to 7.150 MHz and as longas the mode doesn't run over 300 baud per carrier/tone, I can use the whole 150 KHz available for the mode. Relative to 40m, §97.305(f)(3) says Only a RTTY or data emission using a specified digital code listed in §97.309(a) of this Part may be transmitted. The symbol rate must not exceed 300 bauds, or for frequency-shift keying, the frequency shift between mark and space must not exceed 1 kHz. If I understand this correctly, you're right: a non-FSK signal whose symbol rate does not exceed 300 baud could consume 150 kHz of bandwidth. Taking up half of the 40m band for one high-reliability 300 baud link seems rather antisocial. As I said, we should be focusing on doing more with less -- not less with more. Look what Peter G3PLX did with 31 hz! So tell me, in your opinion what did G3PLX do? Peter developed a modulation scheme that is easily implemented on a PC and soundcard, that required no major changes to regulations or band plans, and that enables worldwide communications with modest transceivers, power levels, and antennas. Its uptake in the amateur community exceeeds that of any new scheme since SSB, and it has stimulated the development of many new soundcard-implementable modes. What kind of communications do you need for your 1) pleasure and 2) to support emergency and/or disaster relief communications? For me, CW is just fine to meet my personal needs or perhaps MFSK16 or MT63. But to support the disaster communications work I volunteer for, I need something 10-20 times faster than MT63 and just as robust. Only 10-20 times faster, Walt? Why not 1000-2000 times faster? Don't you need high-definition video with surround-sound audio? Its fine with me if you can convince the FCC to allocate some non- amateur HF spectrum for wide-bandwidth amateur experimentation. My point is that such signals are incompatible with the modest HF allocations we have today, and should not be permitted there, the apparent loophole in §97.305 notwithstanding. 73, Dave, AA6YQ The K3UK DIGITAL MODES SPOTTING CLUSTER AT telnet://208.15.25.196/ More info at http:///www.obriensweb.com Yahoo!

RE: [digitalradio] Winlink Scanning
to both the user and the spectrum to eliminate scanning so the user can tell if a PMBO is available, or busy on an alternate scan frequency. In the case of no scanning, it is CERTAIN he is not busy on an alternate frequency, and if he is busy with a station you cannot detect, then when he transmits his bursts, if you cannot hear that either, then you are out of range, so you do not need to use up a frequency trying to connect when there is no hope of making a connection. This keeps the frequency free for for others to use, doesn't it? - Here is additional information from Steve: --- Quote (k4cjx @ April 14 2005,08:23) Regarding scanning. Most Winlink 2000 stations scan only two frequencies per band. About 40 percent use more than one radio, so that they scan only on the given band. Each scan takes approximately 2.4 to 3.0 seconds. The purpose for scanning is to provide the user with a clear frequency where possible. Airmail reads the frequencies scanned by each station and ONLY CALLS for 3 seconds per frequency. So, after calling for 3 seconds, and no connect what does Airmal do then? I still don't understand why there cannot be one station on each frequency listening on a single frequency and not scanning two or three. Please explain... Thanks... Skip KH6TY -- I'd like to clearly understand this issue, so if anyone can explain, please do so!

Re: [digitalradio] Re: Win Link
coverage along the route (or so I'm told). A number of members have problems hitting the net repeater in the weekly net. Radio procedures are often amateurish. 3. The WinLink concept is a noble effort but won't solve these problems. All of the justification of amateur radio communications is based on the premise that all normal communications will be wiped out. Granted, that occasionally happens (and makes the national news), but in the vast majority of incidents that occur, normal communications (phone, Internet) are much more effective. Yet, the emergency communication systems being paid for (gov't grants) and set up in our local cities are usually amateur radio-based, with little attention to supporting communications via the Internet (which will usually be available). 4. With few exceptions, many of the advances in amateur digital modes are proprietary. Proprietary hardware in the amateur community will never make it. I applaud those who write software and then release it free to the amateur community (ironically, most of the good stuff comes from amateurs overseas). However, almost all of those authors are missing the whole point of the open-source software movement, by refusing to release source code under the GPL. The software is usually released with the restriction that the software may only be used for amateur radio purposes. Not that I mind the restriction, but who in their right mind thinks that some commercial enterprise is going to steal some amateur's source code released under the GPL, and make it into a commercial product? Our local RACES group tried to get the source code to ARESpack to no avail. The source code for FNpack is also not available. It's not like there's much to a software package like ARESpack or FN pack; after all, FNpack was written in Visual BASIC, which NO professional programmer uses (and for good reason). If those who develop amateur radio software would release the source code under the GPL, we'd see a *lot* of improvement in many of these packages, and digital modes would be more widely used. -- Dean The K3UK DIGITAL MODES SPOTTING CLUSTER AT telnet://208.15.25.196/ Yahoo!

Re: [digitalradio] Re: Winlink
of favorable propagation between Stations B and D. Station A does not hear station C or D, station C does not hear stations A or B, but station B hears station D. Station D needs a detector that detects activity in the bandwidth that will be occupied to prevent startup of the link, or station C needs to be able to listen to the receiver output of station D to determine if the channel is occupied. This is just one example. This concern was known to the FCC in 1995 when PR Docket 94-59 was released. The FCC stated: First, the control operator of the station that is connected to the automatically controlled station must prevent the automatically controlled station from causing interference. Second, we are designating subbands to which transmissions between tow automatically controlled stations are confined. So you can see from these statements there is no definition of semi-automatic operation. There are stations with a control operator, and stations that are automatically controlled. It is responsibility of the control operator of the station that is connected to the automatically controlled station to prevent the automatically controlled station from causing interference. Before the sound card mode explosion this was not as big of a problem. After the soundcard mode explosion, unattended stations using PACTOR did not keep up with the times and incorporate the tools necessary to allow the control operator that is connected to the automatically controlled station to comply with the FCC rules. The FCC also stated that we also are confident in the ability of the amateur service community to respond, as it has in the past to the challenge of minimizing interference with novel technical and operational approaches to the use of shared frequency bands. You have to admit Steve, the WinLink community has been dragged kicking and screaming in to the 21st century realization that the bands and modes have changed, and no longer are FSK signals the only kids on the block. 73, Mark N5RFX At 05:40 AM 4/12/2005, you wrote: Please explain hidden transmit effect with an example.
