RE: [digitalradio] Global traffic and emergencies
We all have out opinions. 2.4 KHz is well within the 3.0 KHz bandwidth. The desire of Hams to operate on top of another station is another reason for serious consideration of NTIA spectrum for reliable communications and the discipline necessary to conduct them. MARS still handles some MARSGRAMS also; mostly during holidays, so I see no indication of competition with the license renewal notices and birthday greetings relayed by the NTIS. Unfortunately for those who want to send everything via 500 Hz in serial format, all Federal agencies are looking for something to handle their requests in formatted binary/compressed packages. P1 and P2 can move this along in an environment that is not time critical, but, in all cases, if you want to get the info flowing in large quantity for timely delivery, you have to dedicate the bandwidth to do so. That is why we aren't using 8 bit machines running at 4.77 MHz anymore. Beginning to see a pattern here?

RE: [digitalradio] Global traffic and emergencies
Rick, Andy, All, It is totally unreliable, undocumented and probably not reputable. I can't remember if it was during Huntsville or Dayton that the headshed made these assertions and small publicity came out afterwards. For the most part this discussion has always flown under the radar. It never gets too much attention, and should probably be swept under the rug as uncomfortable. After all, All amateurs can directly interface with FEMA, GEMA, TSA, EPA, and the other Agencies and Federal entities that make up the SHARES network, so there is no need for any division between use of FCC (ARRL) Spectrum and NTIA (MARS / SHARES / Federal ) spectrum. Someone has to provide ground truth reporting of the actual incident, so I guess it should be an Amateur from a few hundred miles out, rather than a local operator using last mile infrastructure. I guess it is more comfortable thinking that the converse is the rule. Think about it. If you were managing communications to save lives and property, would you rely on relay, or direct contact? Would you expect remote reporting of local conditions from hundreds of miles away, when last mile infrastructure was in place and able to do so? Would you use a group that maintained rigid net discipline and regular, daily training, or someone who shows up to an Incident Command center with a dead battery in his HT and hungry? Would you expect your ARRL AREC diplomas to allow admittance to a Incident Command site that is functioning under NIMS, or would you travel with certificates of completion of IS100, IS200, IS700 and IS800A? (MARS is considering requiring both; at present, only ICS for Billet Call holders are required.) Do you know what NIMS is; what ESF#2 is, what the National Support Framework is?. Do you know what TWIC is? (On December 2nd, you certainly will). Emergency Communications is a subject that is undergoing great flux... If wideband digital modes are what is required to send and receive an IS213 form in proper formatting, it stands to reason that any Federal response would require the medium that is capable of delivering. Anything else is inviting failure. If the mode is unwelcome on FCC governed spectrum, and has an active and efficient network on NTIA spectrum, which would you choose? As for non ARQ modes, I have used MT-63, Olivia, and even played with Contestia in 2000Hz bandwidths. Each is somewhat useful for unformatted text and forward error correction. EasyPal looks very promising and the programmers have been very responsive to tailoring it for the MARS program; because someone thought enough to ask. I hope that WinMor will be in the competition with Pactor III and other Proprietary modes, but it will all boil down to bandwidth necessary to carry compressed information. That is what the entire discussion is and has been about. At present, the only way to get the job done to the requirements of the served agencies, on a Federal Response is on NTIA spectrum, as they allow wide-band digital formats. Pay no attention to that man behind the curtain; I was only kidding.

According to HFN International ALE Coordinator Bonnie Crystal, KQ6XA, the main purpose of the Network is to provide efficient emergency and disaster relief communications to remote areas of the world. Beginning with a core group of six North American radio operators in June 2007, HFN rapidly expanded to cover large areas of the planet with 24/7 digital communications, she said.HFN was designed to be an open framework for global Amateur Radio emergency services to interoperate on HF using the Automatic Link Establishment (ALE) system. Relying on ionospheric radio communications, interconnected HFN base stations scan the radio bands every 10 seconds, from 3.5 MHz-28.0 MHz.

RE: [digitalradio] Black Friday deals of interest to hams
On the Dell, better be sure to buy a powered USB hub for Ham use. I spent a few hours getting the sound and printer going on a new one for a relative last week. The Dell USB powered speakers, keyboard and mouse consumed 3 of the rear USB ports. A Brother color laser printer took up the fourth one. Until I was able to balance the load among the 4 USB ports in the back, there wasn't enough current available for stable voltage to get a recognition signal on the bus for Vista to identify the USB items and activate them for use. With most ham software written for Serial ports (which haven't been standard on computers for nearly a decade), the need for high enough current reserve on the USB bus is a must. Dell managed to fall below the minimal acceptance on this model, but a properly powered external USB Hub will probably solve the problem. Otherwise, it looked to be an OK computer for beginner or dedicated purpose. I don't know how the sound card would do on digital modes, but it did have front-mounted line in and headphone out jacks, and the sound applet lets you disable rear channels and special effects for straight stereo and 2 speaker operation.

[digitalradio] Re: Sound card question
The following is an excerpt from the web page Sights and Sounds of Digital Signals, http://www.w1hkj.com/FldigiHelp/Modes/index.htm. THOR Modes General Description THOR is a family of offset incremental multi-frequency shift keyed modes with low symbol rate, closely related to DominoEX. A single carrier of constant amplitude is stepped between 18 tone frequencies in a constant phase manner. As a result, no unwanted sidebands are generated, and no special amplifier linearity requirements are necessary. The tones change according to an offset algorithm which ensures that no sequential tones are the same or adjacent in frequency, considerably enhancing the inter-symbol interference resistance to multi-path and Doppler effects. The mode has full-time Forward Error Correction, so is extremely robust. The default speed (11 baud) was designed for NVIS conditions (80m at night), and other speeds suit weak signal LF, and high speed HF use. The use of incremental keying gives the mode complete immunity to transmitter-receiver frequency offset, drift and excellent rejection of propagation induced Doppler. Protocol These are unconnected, manually controlled message asynchronous simplex chat modes, using binary convolutional Forward Error Correction. The default calling mode is THOR11. Coding and Character Set A binary varicode with ASCII-256 user interface (same as MFSK16) is used. Lower case characters are sent faster. An ASCII-128 secondary character set extension allows a fixed (typically ID) message to be sent whenever the transmitter is idle. Modulation uses two dibit pairs, symbol synchronous, differential. The FEC system uses binary convolution to generate two dibits per varicode bit, and halves the corrected data rate compared to the equivalent DominoEX mode. Rate R=1/2, Constraint length K=7, Interleaver L=10 (40 bits).

You must however abide by the the license under which it has been developed and published. To date one other amateur product has used fldigi source with great success, DM-780, by Simon Brown. DominoEX-FEC and THOR differ in two ways: The FEC table structures in DominoEX-FEC have been manipulated in a way that prevents the transmission of control codes. THOR uses the same FEC table as MFSK and can transmit the full ASCII character set. The interleave used in THOR is longer than used in DominoEX-FEC, and it will have a slower throughput but greater immunity againts multi-path. Fldigi can encode and decode both DominoEX-FEC and THOR. 73, Dave, W1HKJ

Great idea.

Both are much more tolerant of poor band conditions than PSK and who cares if Olivia is slow - you're talking about ragchewing, not contesting. Too, I haven't found MFSK16 hard to tune at all.

RE: [digitalradio] CW - last resort?
Isn't this just precious. . The move is divisive, and obviously geared toward attrition. Navy seems to be leading the charge Chief NAVMARMARS managed to honor tradition, and managed to make policy move back toward the stone age. Nice tantrum. What a comfort. I will sleep better at night. For those that haven't followed the media campaign, MARS is moving toward a Customer-Based Emergency Communications organization. Since they are now involved directly with TSA and other Gov't ESFs, it seems only logical that they should try to pass their customer's traffic in CW. After all, it is more common than Latin, and all of their customers will certainly be able to copy. Further note, I don't think he really views CW as a last resort. .

RE: [digitalradio] ARRL Introduces Fifth Pillar at Dayton HamventionR
Too bad all the potential hams that wanted to hear this 20 years ago are now top Cell Phone engineers, WiFi Gurus, running Satellite Radio stations, etc. Paragraph 4 is the affirmation of this and the effect from the cause. It could have read that professional technical minds have always gravitated toward Amateur Radio as a means of expanding their understanding. But, thanks to the league, they chose to take their talent elsewhere. The league spoklesperson forgot to include the identifier senior hams attribute their affininty to Amateur Radio as launching their professional careers. Somehow, the league's steerage has driven the wheels of the concept of keeping up with technology; until now (Wink, Wink - Nudge, Nudge). I sure hope they didn't miss the chance to break this earth shattering decision to the world on a CW broadcast. Oh. Wait a minute; I have erred. That should have read a RTTY broadcast - After all, this is the 21st century. The league of exceptional shortcomings in foresight has spoken again. Don't tell these guys about USB or Firewire interfaces - it might confuse them... David KD4NUE ***- ARRL Introduces Fifth Pillar at Dayton HamventionR On Saturday, May 17 at the Dayton Hamvention, ARRL President Joel Harrison, W5ZN, plans to announce that the League will expand its identity program to include greater emphasis on technology. Harrison explained that Ham radio operators, and particularly ARRL members, closely identify with current and emerging radio technology. Today, we are naming 'technology' as ARRL's new fifth pillar. ARRL's other four pillars, the underpinnings of the organization, are Public Service, Advocacy, Education and Membership. For hams, expanding the four pillars to include technology will reinforce one of the organization's guiding principles -- that ham radio is state-of-the-art, innovative and relevant, he said. Radio amateurs have entered a new era. More than a dozen Amateur Radio satellites are presently in orbit with more to come. Software is expanding the capabilities of their radio hardware and communication by digital voice and data is expanding rapidly among hams, Harrison said. In addition to the new fifth pillar, the ARRL has launched a year-long ham radio recruitment campaign emphasizing the Amateur Radio Service as a scientific national resource. The campaign invites newcomers to discover ham radio in the 21st Century -- where hams are using science, technology and experimentation to explore the radio spectrum. For more than 90 years, the ARRL has been at the forefront of technology, encouraging experimentation and education through its license training resources, publications and periodicals. ARRL provides its members with top-notch technical information services, trusted product reviews and radio spectrum advocacy, Harrison said. The ARRL Laboratory is a centerpiece of ham radio technology, contributing to radio electronics experimentation, spectrum development and advocacy, and radio frequency engineering. Harrison also noted that many hams attribute their affinity to Amateur Radio as launching their professional careers in radio engineering, satellite communications, computer science and wireless communications. This is less about defining a new course for Amateur Radio, but simply recognizing a course that has always been a precept of radio amateurs and the ARRL, he said. Referring to the federal rules and regulations for Amateur Radio, Harrison explained that one of the defining principles of the Service's very creation by the government is the amateur's proven ability to contribute to the advancement of the radio art. Harrison remarked, Today's technology is nothing new to ham radio! Page last modified: 03:06 PM, 16 May 2008 ET Page author: [EMAIL PROTECTED] Copyright C 2008, American Radio Relay League, Inc.

[digitalradio] how ?
yesterday looking around 30m with psk(not sure if 31 or 63), i saw, but did not catch the tail end of a signal in the waterfall with a 73 printed after it. this did not look like an video id as used by multipsk. this signal was simply formed by the psk signal itself. anyone got an idea ? david/wd4kpd
Re: [digitalradio] Re: another non- contest on a no contest band
Hi AllSSB is allowed by all countries on 30m.. SSB stands for Single Side Band and is a form of modulation and not a Mode as suggested by some.many people use SSB to mean Speech or Voice which is a Mode and a misuse of the term SSB. RTTY is sent in LSB or Lower Side Band form of SSBmost digital modes are USB another form of SSB.all allowed on 30m. i think you will find in most Amateur Radio Regulations of all countries that Voice or Speech is donated as such and not SSB Yes i know this is a usage hangover from the 'wars' between ops of AM and SSB but by now should be buried and the terms used correctly.AM Voice or SSB Voicejust as the new technology is being called Digital Voice The misuse of terms is also confusing to new hams who in classes are taught correctly..

The 30m is perfect for that, exactly because there is no event, no contest, no pile-up, no DX chasing, ... Well, because it's quiet and there is a lot of free bandwidth for experimentation. I don't know about other country, but the french law explain in the radioamateur definition that you can transmit ONLY for learning purpose and technical experimentation.

But i'd like to keep the 30m for learning purpose and experimentation... as it's supposed to be on every band. That's why i'm personally against this non-contest/event/weekend.

RE: [digitalradio] Re: 10 Tips for the PSK31 Digital Mode
One more consideration is AGC recovery time. Slow AGC and static crashes are not a good combo in many of the digital modes. No AGC or Fast AGC will make a difference in that situation. This may not apply to PSK-31 as much as more complex digital modes, but a point worth considering. DSP filtering of signals above and below the signal you are trying to copy are also a great help; if your rig will allow that narrow of a passband. David KD4NUE -Original Message- From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of kh6ty Sent: Wednesday, March 12, 2008 4:13 PM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] Re: 10 Tips for the PSK31 Digital Mode There is no difference between an RF gain control and AGC. AGC is just Auotmatic Gain control instead of manual gain control. The only way to copy a weak signal adjacent to a strong one is to prevent the strong signal from affecting the AGC, and the only way to do that is by using a narrrow filter or notch filter (at IF, not audio) to attenuate the strong signal. You can use a wide (SSB) filter to see all the stations in the passband, and then use Passband Tuning or IF Shift, or a narrow filter (at IF, not audio!) to narrow in on the station you want to work if it is one of the weaker ones. You do not need to do anything for the strong signal unless it is overloading your front end and then you can switch in attenuation and switch it out again when you are finished. Many people have experienced a weak PSK31 signal disappearing or waterfall darkening when a strong signal comes on. This is because the strong signal is reducing the gain (and therefore the noise background), just the same as if you manually reduced the gain, and generally the only cure for this is using narrow filtering. Some receivers, designed specifically for PSK31, such as our latest PSK-20, do not use AGC, but distribute gain in such as way that it can copy weak signals adjacent to strong ones, without distorting the last IF stage or detector, but few transceivers can do this. A dual-loop AGC system may help and some high-end transceivers have this. 73, Skip KH6TY

RE: [digitalradio] MARS WinLink in Tennessee Storms
It is interesting , isn't it? MARS doesn't hold contests. MARS doesn't allow stations to intentionally interfere with other stations. MARS doesn't promote awards for the number of contacts you can make in a minute and not say anything. MARS doesn't get their panties wadded up when information is exchanged without being interfered by contesters, QRN or jammers. Army MARS offers training during 90% of it's net operations. MARS has requirements for membership. MARS promotes discipline and efficient operation. MARS gets to play on NTIA spectrum and doesn't have to subject itself to the bonfire of vanities experienced on ham frequencies. Kid of sets a precedent, doesn't it. This probably goes as far as any other single example to explain why the ARRL relegated the Amateur Radio community to the realm of last mile (VHF) communications in support of emergency communications and abdicated the HF realm to the Tri Service MARS organizations. Bread and Circuses has worked since Roman times; why should this be any different. The ARRL knew when to throw in the towel, and had a pretty good idea about the quality of their members; as well as their devotion level to do the tasks traditionally required of the Amateur Radio Service in exchange for the spectrum they enjoy. The operation has been a success; the patient is definitely dying Pactor III is probably more effective than CW ever was as a 'filter to determine the dedication level of emergency communicators. But, you have to consider that there is not a HF rig less than $500.00 new, and entry level for a HF rig that utilizes the best of 20th century technology starts around $1200.00 With that said, you can begin to appreciate that the $900.00 cost of a Pactor III controller (taking advantage of the 10% discount for Emergency Communicators) will deliver the mail, with the cheapest HF rig. A PTC-IIex controller connected to an Icom IC-718 cost about what an IC-7000 or a little less than a TS-2000 costs; in a field of choices that can cost up to $15,000.00 for a HF rig alone. The Contest Grade of transceivers that go north of ten grand will clog up the airwaves and render them unusable by others far more often than Pactor III and WL2K. Anyone saying that frequency usage during a contest is less adversely affected than by WL2K transmissions using Pactor III is sadly being less than truthful with their self and others, and there is simply no room for discussion to the contrary. A little intellectual honesty will trump knee jerk reaction every time Emergency Preparedness in our county in Glynn County, GA currently includes 8 SCS Pactor III controllers. At least 4 more are scheduled for purchase prior to Hurricane season. The reason for this is that nothing else will come close to the throughput and devotion of the WL2K system when other infrastructure is down. The county services have now learned the importance of owning their own amateur radio equipment and promoting operators from within their ranks to be able to have the additional layer of communications infrastructure available and in play during time of emergency. I would say this is a wake-up call, but, sadly, wake-up calls concerning the Amateur Radio Service are a small spot in the rear-view mirror. So, it is entirely predictable that the Amateur community would resist WL2k and Pactor III. It does what they no longer have the devotion to do. I continue to refine my ear, and ability to work voice under less than optimal conditions. I continue to refine my station(s); fixed, mobile and portable in an attempt to be prepared to do the job required to retain the Amateur Radio Spectrum. Pactor III is a tool that I use very sparingly. I am very fortunate to be able to use it freely on the NTIA spectrum, and, given a choice, it is a no-brainer which service will handle the most traffic during an emergency situation. To a T, the amateur radio community will continue to resist, until they have no ground under their feet. Spectrum refarming is very lucrative for funding . The FCC may seem slow, but they do have a little more will to survive than others under their blanket seem to... All in all, it is progress. The direction it is taking isn't pretty, but the outcome will include Pactor III, I am not too sure it will include Amateur Radio...

Hi Jack.you will note that the digitalradio group is populated by mainly US hams who love nothing but arguing among themselves about the merits of various digital modes.and the regulations controlling them they forget that they are only a percentage of the Amateur Radio Operators from around the world and we who are the others are having to put up with there arguing on two occasions i have withdrawn from this group due to the fact that two thirds of the e-mails coming into my mailbox i dont want to read as they are nothing but rubbish that doesnt interest this ham who lives in another part of the world i have suggested that maybe another group be started so that those who want to argue there points of view do so away from the rest of the world who are interested in DIGITAL MODES and DIGITALRADIO without all the arguments.This idea has not been taken up... im considering removing myself from this group again if the arguing continues much longer 73 David VK4BDJ Jack Chomley wrote: I think these discussions about ALE who, PSK this, who hates Pactor etc are starting to destroy this group.

I would cite a lack of knowledge of modes and bandwidths etc on his part, maybe he thinks the various digital modes all have retrys and error correction..so it will just sort itself out and all modes will simply share frequencies! Yesterday, I was on 20m and I heard a stack of signals which were not Pactor (I had a Pactor sked setup) I switched to PSK31 on my hardware boxno go. I fired up HRD on my SLUSB, still no go :-( I was not sure what signals they were, to be able to try and resolve them, being just interested in what they were. Being a little tone deaf and not having an intimate knowledge of all the modes and what they sound like, did not help me. Were they MT63? PSK250? I don't know If you run Digipan, you have no hope! With the increasing number of new modes being developed, the problem will get worse :-( Add the coming of improved propagation and this will become a spectrum quagmire in which no one will be able to operate easily. We have all helped create the mess we have. A gazillion software programs, all doing their own thing some with many modes and expanding more modes, nearly daily, others that don't have so many modes. No software that I know of has a decoder function, with an identify signal menu. Unless the software guys can come up with something like that as an integrated or standalone solution, the schemozzle will get worse. IF people can identify a signal, with callsigns, they will be less inclined to interfere with it, if a operator can't resolve a signal.they probably care a lot less about any interference to it. Sadly, only soundcard software solutions can be given this signal decoder ability, hardware boxes are a different deal. You need operator digital modes knowledge too, many people do not know what all the modes sound like, I know I don't, even though I have a recording of mode sounds that someone on the group was good enough to post! Now, this is not bagging all the good people, who do software development for the benefit of Hams, for little or no cost BUT..

I would cite a lack of knowledge of modes and bandwidths etc on his part, maybe he thinks the various digital modes all have retrys and error correction..so it will just sort itself out and all modes will simply share frequencies! Yesterday, I was on 20m and I heard a stack of signals which were not Pactor (I had a Pactor sked setup) I switched to PSK31 on my hardware boxno go. I fired up HRD on my SLUSB, still no go :-( I was not sure what signals they were, to be able to try and resolve them, being just interested in what they were. Being a little tone deaf and not having an intimate knowledge of all the modes and what they sound like, did not help me. Were they MT63? PSK250? I don't know If you run Digipan, you have no hope! With the increasing number of new modes being developed, the problem will get worse :-( Add the coming of improved propagation and this will become a spectrum quagmire in which no one will be able to operate easily. We have all helped create the mess we have. A gazillion software programs, all doing their own thing some with many modes and expanding more modes, nearly daily, others that don't have so many modes. No software that I know of has a decoder function, with an identify signal menu. Unless the software guys can come up with something like that as an integrated or standalone solution, the schemozzle will get worse. IF people can identify a signal, with callsigns, they will be less inclined to interfere with it, if a operator can't resolve a signal.they probably care a lot less about any interference to it. Sadly, only soundcard software solutions can be given this signal decoder ability, hardware boxes are a different deal. You need operator digital modes knowledge too, many people do not know what all the modes sound like, I know I don't, even though I have a recording of mode sounds that someone on the group was good enough to post! Now, this is not bagging all the good people, who do software development for the benefit of Hams, for little or no cost BUT.. Someone bright enough to do it...is going to have to write that signal decoder program very soon.otherwise this whole problem will get worse. Fixing the WinLink problem is another deal altogether. 73s Jack VK4JRC Hi Dave CW id is not universally understood..i for one have a hearing problem and CW is very difficult for me to hear let alone decode...also what about those who are deaf...we do have a number of them around the world... most are now using digital modesi have worked a deaf op on PSK31 and i wouldnt have known he was deaf until he told me... today there are also many new hams who havent had to learn CW as it is no longer a requirement for a HF licence in most countries... 73 David VK4BDJ
Re: [digitalradio] JT65A reports
Barry Garratt wrote: Hi Dave, Actually what you describe is EME reports as opposed to Terrestrial reports. The OOO and RO are used for EME but are also the defaults in so much as the JT65 modes were initially mainly used on EME. Either will constitute a good contact as long as RRR is exchanged. The 73 exchange is not required for either EME or Terrestrial and is really just a courtesy. Usually you will see new stations both in EU and the US using the EME protocol until they have gained some experience and or someone has explained how to send terrestrial signal reports. Hope this helps. 73, Barry VE3CDX/W7 *From:* digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] *On Behalf Of [EMAIL PROTECTED] *Sent:* Saturday, January 05, 2008 9:24 AM *To:* digitalradio@yahoogroups.com *Subject:* [digitalradio] JT65A reports There seems to be a difference btween reporting systems between the US system and the European system on terrestrial JT65A contacts. Can anyone explain to me when a contact is 'valid' between two stations using the two different systems please? For example, I received the following today (callsigns obscured to not cause offence) on 20M 163700 12 -2 0.0 5 4 * CQ EA*** JM** 1 0 163900 10 -5 0.1 5 3 * G0DJA EA*** JM** 1 0 164100 6 -6 0.0 5 3 * G0DJA EA*** 1 0 164300 10 -15 4 3 RRR ? That was it, no report, not even OOOs. I was using what, in the guide, says is the European standard of sending the received dB signal strength, but the EA station was using the US version, appart from no OOO. A quick read through the excellent Bozos guide gave me the clue that the other station was double left clicking on callsigns (US system reports)and I am double right clicking (Eu system reports). Now, two questions occur to me at this point. 1. Is my EA contact 'good' or 'incomplete' and 2. What's going to happen when US stations and Eu stations work each other? I wonder why two reporting systems were created for terrestrial JT65A? My guess is that the US one will win out anyway, as that just seems to be the way these things go and left clicking is more the norm than right anyway, so why the alternative systems? Also, whilst I'm asking questions, why does double right clicking automatically turn Auto TX to ON? If you are not careful, and want to pre-load a callsign to call at the end of an existing QSO, you end up accidentally TXing over the top of the person working the station you want to have a go at next. This seems a bit like poor operating and it's not untill you do it for the first time that you realise what's happening... Thanks for any help with these problems I'm having - Dave (G0DJA) Hi Barry..as far as i can tell the 73 exchange is still needed for a complete contact. look in WSJT 6 Help Examples of minimal JT65 QSO's and both styles of EME and Terrestial are shown.i understand there has been some talk about this with Joe Taylor and his statement is that the minimal shown is the way that it always has been on CW or SSB some ops are very fussy about the 73 and ive had them send it several times until they get a 73 reply. hope to work you one day on JT65A 20 or 30 m 73 David VK4BDJ

Hi Everyone, I've been following this debate for the past several days and finally have to add my two cents. I'm part of NTSD, that's the National Traffic System Digital...We mostly use the old version of Winlink (before Winlink 2000) also reffered to as Winlink Classic running Pactor I II and sometimes III... We used to use AMTOR and Clover but have all changed over to Pactor... Many of us are still using PK-232MBX's for Pactor I, others are using SCS TNC's All our connects occur in the automatic band segments... Winlink Classic has a very good busy detector in it... I've seen it work on not only Pactor, AMTOR, and Clover signals but other including RTTY, dead carriers etc... Winlink classic when it hears another signal, postpones the connect and then tries 15 minutes later for a total of three attempts at a clear frequency. I can tell you that with an active busy detector, our systems are almost helpless against RTTY signals that come into the automatic band segments especially during contests... Traffic thru put declines severely during these contests. We're happy with staying within the automatic band segments with our 500 Hz Pactor I and Pactor II signals... It would be nice if others realized that the automatic segments do contain stations with busy detector armed and ready and please refrain from casual operation there, especially during a contest. I know I'm going to get a lot of flack from those of you that don't like automatic stations, but like I said Winlink 2000 is not the only Pactor operation around running automatically... We prefer to stay in the automatic band segments... Please have the common courtesy to respect our operations.

Dave, Thanks for your comments... We do make substantial use of 30 meters on a regular basis... However, within Eastern area we also rely heavily on 80 and 40 hence my comments By the way NTS has been around for over 50 years. Are your suggesting that we discontinue operations, especially during a contest?

I'm glad to hear that you are using a busy frequency detector, Dave. The detectors in PK232 and SCS modems are certainly better than nothing, but are quite limited. Neither detects PSK31 transmissions, for example. As part of the SCAMP project, Rick KN6KB (a member of the Winlink team) developed a soundcard-based busy detector that was reported here to be very effective at detecting most modes found on the ham bands today. I have repeatedly suggested that Rick's detector be incorporated in WinLink PMBOs -- a straightforward and inexpensive process -- but there has inexpicably been no progress on this front for several years. Our HF amateur bands are a shared resource; no one can stake a claim of ownership of any frequency or set of frequencies unless an emergency has been declared. If contests draw more amateurs to the HF bands -- as intended! -- then yes, there will be more congestion and it will be harder to find a clear frequency on which to exchange messages. Using HF amateur bands to offer a message passing service with guaranteed quick delivery times is simply incompatible with the defined usage model for these bands. There are techniques you could use to optimize performance -- like QSYing to the WARC bands during contests -- but nothing short of exclusively-assigned frequencies would enable you to achieve a guaranteed Quality-Of-Service. I personally don't think the assignment of exclusive frequencies to specific sub-groups is consistent with amateur radio -- except during a declared emergency. 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, David Struebel [EMAIL PROTECTED] wrote: - Original Message - From: David Struebel To: [EMAIL PROTECTED] Sent: Thursday, December 27, 2007 4:33 PM Subject: Re: [illinoisdigitalham] Will You Let FCC Kill Digital Radio Technology?

I do not believe these digital modes will be effective in a true national emergency. I do believe that they use a disproportionate amount of bandwidth for no real advantage. Email at less than 2400 baud is not cutting edge technology. In a real national emergency SSB and CW which depend on the operator's ear and not external devices are the only dependable modes. I agree with this petition, the author has given much thought to it.

I presume it does the same thing as Dimension4 does for Windows as i notice it uses a net time server Yes this is done via a modem interfacing to the net... i dont know of a way to do this via a radio and a time signal station such as WWV or WWVH...

HE SHOULD NOT HAVE CALLED ME FROM SO FAR AWAY USING WHAT AMOUNTS TO AN RIT IN EFFECT. GUYS...PSE TRY TO TUNE TO THE SYNC TONE USING THE RF DIAL, NOT THE CURSOR. GUD DX/WD4KPD please ignore caps...had finished text before i noticed it.
[digitalradio] help prevent qrm
20m was a mess today, everyone planting on 076. this is not necessary ! try this... set in spectrum the jt65 DF axis option freeze the program to 0, with tol to 200 tune whichever station you wish to tune by shifting your dial to place the sync tone on 0 the 200cps tol will effectively give you a filter 400cps wide around the other stations rf freq and it will not decode anything outside the window, this eliminates lots of qrm to you. if you rig cant quite tune that close, when most of the other stations tones are withing that window you can re-freeze the idea is to not use a large DF and take up more space than needed, and spread everyone out a bit. 300cps is more than enough to ensure no qrm. daivd/wd4kpd

Original Message Subject: channels Date: Thu, 05 Apr 2007 11:24:20 + From: David Michael Gaytko // WD4KPD [EMAIL PROTECTED] To: Harry Popov [EMAIL PROTECTED] hello harry well regarding the sideband issue, my understanding is that it was done that way because of the technical limitation of the mixer or sideband filtering method of the rigs back then would no allow the lower frequencies to maintain the mark high for RTTY. i don't think there be any modern rig today that has this problem. so now it is only because of tradition that this is still done. it could be changed. as to the channels, with modern rigs 100hz is routinely done, and all the stations i worked these past few days on wsjt have all been well within this tolerance. it seems that at least trying would be better than taking up unnecessary space by trying to qso with a very wide df. just trying to help. david/wd4kpd

[digitalradio] jt65a channels ?
working last eve on 20m was fun, but when you work another with a large DF, you take up more space than necessary for a qso. also with the popularity growing, i think would be nice for a bit of channelization. suggestion that if 076 is the center of the band, and since WSJT can search over a 600cps range, that we establish a few channels. such as 075.3/075.6/076/076.3/076.6 etc, every 300cps. this gives a little guard band around each channel and will still pass all data. all you got to do is dial in the channel with dial freq, and freeze with a 200cps tolerance. with the accuracy of hf rigs today, anyone can do this and get within 100cps where you can capture without going to a df that covers another channel. with a little cooperation, this can be fun ! lacking VK S.America for wac on jt65a. what say ? david/wd4kpd ps.some standardization should be considered as to which sideband to use on each bandit was set out a ways back that USB was going to be used for all digi modes, except RTTY regardless of the band. should this standard be used, or should WSJT be operated like RTTY ? its not a real big problem yet, but with more ops, its gonna be.

WB0UNB was also able to receive my first digital picture transmission. Someday I'll get a PC with XP down in the shack and download EasyPal and it will all go a lot easier. But it's fun teaching an old dog (not me, but my TS-120 as well as my laptop) some new tricks... David WB2HTO

Live with it, and get used to it then QRM it. david/wd4kpd
[digitalradio] intentional QRM
for all intents and purposes, when Winlink transmits into the blind on a shared channel, that is intentional QRM. so by doing so, they are advocating QRMing others just as i suggested. i agree that my language was a bit overboard, and apparently in poor spirit, but please don't point me out as the sole abuser. i promise Andy, this will be my last on this issue. david/wd4kpd
[digitalradio] Olivia
Okay, I have downloaded and installed MultiPSK and am ready to try this new mode out. What are the best frequencies and times to listen for Olivia signals? Also, I understand there are variations in the mode - what do I operate and where?
[digitalradio] Re: Anyone using DigiTRX (Ver 3.11) for ditigal TV?`
Thanks again for everyone who has chimed in. The contest this weekend has made contacts difficult, but conversations with WD4KDK, N0TAO, N7AXL, and W0CYF and reading the postings I am pretty sure that between Windows Me (a real piece of you-all-know-what) and the relative slowness of the PII 166MHZ processor (which works fine with SSTV, PSK31, and RTTY) I'm not going to get very far with digital.

Thank you Howard, Andrew, and the others who have chipped in with suggestions. The PC is a Dell laptop PII at 166MHz, which makes your oldie look like a newie Others have also told me DigiTX won't work, neither will HamPal. I'm trying WinDRM but today is the contest and the band is jammed with people making 2 second contacts (how fast can *you* talk?) As to your question about the constellation, I have psoted a picture of a sscreen shot of DIGITRX during an unsucessful receive. http://www.bambinomusical.com/Constellation.jpg http://www.bambinomusical.com/Constellation.jpg --- In digitalradio@yahoogroups.com, w6ids [EMAIL PROTECTED] wrote: Hey Dave As I understand it, DigiTRX won't run on less than WIN XP.. I tried it with Win98 and failed to be able to transmit. I WAS able to receive pictures and I've been told that wasn't quite normal. Others have not been able to get Digi going on anything other than at least XP; the programs allegedly have been written for no less than that OS. Others have said that you need at least a 1 Ghz machine to make things go in Digi... I haven't seen that myself - my DigiTRX is working just fine. I only need to acquire a linear amp to get the transmit going. I run DigiTRX myself on a PIII @650 Mhz..an oldie. Personally, I like DigiTRX over the current offerings but I've never been one to follow the pack as it were. What do you mean the constellation never stabilizes? Can you pass along your settings as you have them? I noticed that Andrew sent you a message. He's pretty good with the Digi thingies.

[digitalradio] 160M digital meeting place
guessing the freq is around 1807, but when ? david/wd4kpd
[digitalradio] just wondering
getting interested in jt65 via hf. as all digital stuff i have ever seen in us and eu has been usb on the low bands, would kinda like to keep on usb for jt65/hf. there was a little mix up this morning with JE on 40m. just wondering what may be the consensus ? additionally, i think jt65c should do the best on hf as it does on 1.2ghz and up EME (as i understand it). seeking comments on this. david/wd4kpd
Re: [digitalradio] One last try for FSK keying
You should be able to pick up a used Pk-232 or KAM on Ebay for less than $100.00 Dave wrote: I've burned up a lot of bandwidth in my quest for a way to key my IC-746 (non-Pro) with FSK instead of AFSK RTTY, so this will be my last post on the subject. I'm looking for a used interface, TNC, or what-have-you that will allow me to use the RTTY mode of my 746 rather than USB/LSB. Can't afford new, or it would be easy. If someone has a working TNC, such as an older MFJ, AEA, KAM, or perhaps an interface of some type they would be willing to part with for a good price, I'd be pleased to give it a good home. I don't care if it has PACTOR or AMTOR, or any other modes except RTTY. All my other digital modes are set up for my sound card.

Re: [digitalradio] Re: New ARRL Petition
Just so you are aware. There are some of us who don't think that Winlink 2000 is the answer to our prayers. Most of NTS Digital is still running Classic Winlink 2.9 which doesn't offer internet forwarding and relies upon direct forwarding from each Winlink NTSD station via RF. We favor automatic operation in the assigned automatic sub bands. In fact most of our operation is confined within these sub bands. Elimination of the auto control sub band is a real problem to us. We plan to migrate to 3592 and 3594 in semi-automatic mode after Dec 15. That is a manually controlled station will have to initiate the connection. 73 Dave WB2FTX Eastern Area Digital Cooridnator NTS Digital Danny Douglas wrote: He appears to either be dishonest or ignorant.

I assume from your earlier sallies that you have some standing within this group, but it shouldn't lead to harumphing about comments that may not be exactly precise in discussing what is abstruse material anyway. What I find fascinating in the latest petition emanating from Newington is the ARRL's continuing fixation on WinLink 2000 and its concurrent inability to explain to members why WinLink is being given priority status in its Washington operation. After all, you only have a few arrows in the quiver, and it seems ARRL has gone to the mat for about 5,000 radio amateurs who use this mode from time to time and ignoring the loud objections from the remainder. Meanwhile its other Washingto initiatives are withering, not to mention that last week the League came close to calling the FCC Chairman dishonest.

Fully automatic means that the automated station will issue connects by itself. ... Semi-automatic operation will move below 3600 Khz after the 15th, in the 3590 to 3600 region. Hi Dave, There has been some misinformation posted on groups and websites about Automatic operation on 80 meters. It is understandable that many hams have been confused, with all those errors and confusion in the recent FCC ruling. But, there are also a few hams who are trying to exploit the confusion by spreading disinformation. In fact, it would be quite difficult to get a handle on what is automatic and what is non-automatic, since automation is a moving target in our changing world of technology. In the FCC's Amateur Radio Service rules, as far as I know, there are no such terms as Fully Automatic or Semi-Automatic used. If anyone can point out these terms, please elucidate. The new omnibus FCC rules for December 15th are *completely silent* on the topic of automatic stations. In fact, it seems that... whoopsy-daisy, the FCC forgot to read their own rules about them :) The only reason data/texting stations in USA, automatic or manual, are all moving below 3600kHz is that the subband above 3600kHz is scheduled to become a CW/Voice/Image subband for Extra Class licensees on 15 December. This will happen unless there is a stay issued by FCC in response to ARRL's recent petitions, for the FCC rules taking effect. Even if the stay doesn't happen, emissions still remain available for compliant automatic use in the 3500kHz to 3600kHz subband for data/texting/500HzBW-image. Automatic operation will continue in the 3500kHz to 3600kHz range in USA. There are many automatic stations, many types of automatic stations, and thousands of ham operators who use these stations for their enjoyment of ham radio, for emergency service, and for safety. All of us will be packed like sardines into the 3500kHz-3600kHz subband now. It benefits all of us, for good spectrum efficiency, for all the automatic stations to run fast data... as fast as they possibly can. That leads to one of the reasons for my recent proposed changes in the 80m bandplan and digital keyboarding calling frequencies. These help to provide a foundation for hams to effectively separate the relatively different techniques of time-efficient fast digital automatic operations from relatively bandwidth-efficient manual keyboarding operations.

Re: [digitalradio] Re: New ARRL Petition
There are other digital automatic users besides the email Winlink 2K systems you cite. The National Traffic System (certainly a part of ham radio, and has been around for over 50 years) uses the automatic section of 80 meters for passing traffic thru the NTS Digital system. The FCC new rule would prohibit this operation on 80 meters. Dave WB2FTX Eastern Area Digital Coordinator NTSD kd4e wrote: Must we wait for the FCC to request comments on the ARRL request or should we post our opposition immediately? Sure do not understand why a neo-commercial digital app (all automatic and most semi-automatic unattended digital modes) cannot find a more appropriate home on non-Ham spectrum. Surely between marine and homeland security spectrum there are places for that stuff, since much of it is marine communications and the justification for the rest has been mostly for homeland security apps. Just when you thought it was safe to go back into the water ... Sigh ... doc Rather, we ask only that the Commission restore the privileges unintentionally withdrawn from those who operate and who utilize automatically controlled narrowband digital stations between 3620 and 3635 kHz, the League said. The ARRL pointed out that while the RO left unchanged rules permitting automatically controlled narrowband digital in that segment, it eliminated RTTY and data as permitted emissions above 3600 kHz. end quote This confirms the conclusion that the FCC's Omnibus Report and Order in its present form would eliminate automatic and semi-automatic operation on 80m. It will be interesting to see how rapidly the FCC responds to the ARRL's late-in-the-game petition. 73, Dave, AA6YQ -- Thanks! 73, doc, KD4E ... in sunny warm Florida :-) ~~~ Thank our brave soldiers this season: http://www.letssaythanks.com/Home1024.html http://www.letssaythanks.com/Home1024.html ~~~ URL: bibleseven (dot) com
[digitalradio] how to make a good mode
a question is it better to spread the componets of a data stream across a band width of frequencies along with some type of redundancy, or have several independent streams with same info in each with maybe some type of time delay per stream ? like maybe 5 or so psk streams of independent data set side by side. david/wd4kpd
