OT!!! Re: [digitalradio] cognitive radio systems;?
Same here. I do not operate digital modes at all personally, even those I helped to create and/or improve. I operate 160m and 40m CW almost exclusively. That does not stop me from conducting experiments, doing design work, and using the brain I was given to learn and expand knowledge. I believe this is in the highest tradition of amateur radio and should continue. When that stops, I have lost interest. Simon and I and many others like us write lots of code and do lots of experiments. And rather than look at the development of all of this as dehumanizing, I view it as humanist in the extreme. It is an enabler of new things by the HUMANS using the new capabilities. I think we should leave philosophy and concentrate on digital radio here probably. CR is here to stay as is SDR which has been around for a long time. In my case, I was doing SDR for work two years before Mitola popularized the term. I am happy amateur radio OPERATORS are benefiting now from that experience and effort.

So long as vanity repeaters are put up by people who are willing to become litigious, this is a war that will have MANY casualties.

Bob Bill V WA7NWP wrote: I first heard of cognitive radio systems when efforts were underway to make use of the 'white space' in the television broadcast bands. The whole idea is to make more efficient use the the spectrum by putting situational awareness in to the client device. One example we're discussing is how to use the repeater channels (over allocated - under used) for data when the repeaters aren't in use. Cognitive radios could learn which channels had the least use and make more use of them. There are issues to be resolved but the concept is promising at the very least.

Re: [digitalradio] cognitive radio systems;?
Cortland Richmond wrote: One problem with cognitive radio is that it seems it will be designed to detect only emissions similar to those it is meant to receive. Therefore, it is best used in spectrum particularly allotted to just those kinds of emissions. This rather defeats the purpose of white space. RMS Express by way of contrast has a busy detector that will prevent transmitting over many kinds of modulation different than it uses. Compare this with (say) ALE, whose polling (encountered on MARS frequencies) takes no account of voice or even Olivia on channels it happens to select. Cortland KA5S This is not correct in my experience. In all serious systems under development, the CR is looking to characterize all energy to some degree or another, irrespective of whether it is a matched filter to a particular waveform. The purpose is to find a channel that works. Energy on the channel is an indicator it would not as the source would be cochannel interference and with some high degree of probability, the interference would be mutual. Dislike for any particular system which automates channel usage but does not behave responsibly is not to be used to condemn responsible digital system developers. The enforcement of this responsibility is done by pressure (peer) and performance (being interfered with by those not detected).

RE: [digitalradio] Help with FLDIGI ..
Hi Ron, Not clear from your message is if you've got sound card connections made up also. I'm having to guess that if MixW and HRD are working for you using data modes over the air that you do have a working sound card setup. The CAT cable is only going to be able to set and read the frequency of your radio, and control or retrieve mode information - and that direct-connection operation will only work if nothing else is using the serial port at the same time as fldigi is trying to use it. PC hardware inherently allows only one software program or driver to use a particular serial port at a time. So you might need to close one or more other programs before fldigi can capture the serial port for CAT operations.

[digitalradio] CQ WW contest has a new category, XTREME
For those who are amateur radio operators and are interested in software radio, cognitive radio, diversity reception, and other such things, the contest committee at CQ Magazine has put together a new category of operation to help promote innovation. The brain child of K3LR and K1DG with support from many other members of the committee made the following official rules and the announcement follows. Doug, K1DG, came to the SDR forum at Dayton and announced it directly to us (before the contest forum heard the official announcement). The Xtreme class is anything goes within reason and within reason is clearly defined and quite generous. Who knows if the within reason will continue to be as generous as this but the developer/geeks are clearly having the gauntley throw down. Some fantastic experiments can easily be foreseen. At the contest forum at Dayton, it was revealed that banks for Perseus receivers had been deployed around the world to record the contest and some truly fascinating analysis and use was made of these recordings. I am personally interested in being on a team to develop and operate in this class but please contact me OFF LIST, direct email. Here is the official announcement. Please, take this and send it everywhere you can think of where we might gather some interest. Bob McGwier N4HY -- This year at Dayton, the new CQWW Xtreme categories were announced. These new categories (single-operator and multi-operator) have been established to allow amateurs to participate in the CQ WW Contest while experimenting creatively with Internet-linked stations and other new technologies that currently are not permitted in any of the existing contest categories. The full rules for the new Xtreme Category, as approved by the CQ WW Contest Committee, appear in June CQ magazine and also at: http://cqww.com/CQ_WW_Xtreme_Rules.pdf This PDF file may be copied and re-posted to other Web sites as long as this text is included: Reprinted with permission from the June 2009 issue of CQ magazine; copyright CQ Communications, Inc. Please forward this email to your local club reflectors and newsletters. The new categories are effective with the 2009 CQ WW Contest later this year. In essence, (almost) anything goes! The almost part means that you must obey the rules of your country, including power (up to the CQWW 1500W maximum), licensing, and remote operation (if you use it). It is permitted to use multiple transmitting sites with one callsign (if legal in your country), but all transmitting sites must be located in the same country and CQ zone, and only one signal is permitted on a band at any time. Single-ops with packet, Skimmer, robot stations, on-line databases, etc. are OK! Multiops with remote operators and remote receiving sites around the world...OK! The initial response at both the Contesting Forum and SDR Forum at Dayton was very positive, with some of the SDR Forum attendees actually challenging each other in public!

RE: [digitalradio] Question for the Linux gurus
Hi Dave, First would be to make sure there really isn't support for it. If you can get to a bash shell, and get logged in as root, you can run ifconfig, and see if it lists the USB ethernet adapter. I say this from the perspective of an even older laptop, for which I had (of all things) a parallel port to ethernet adapter - and the installation I did recognized the presence of the adapter, and initialized it. Run ifconfig -a and note what interfaces it comes up with - probably just the loopback interface, but if the laptop has an infrared port, it might also be reported. Then plug in the USB ethernet dongle, wait 10-15 seconds for Linux to enumerate the device, or if you're running from CD, perhaps longer - wait for the CDROM drive to spin down? Then run ifconfig -a again and see if there's a new interface. At that point, if it's connected to a network with a dhcp server, you'll probably have a working network connection.

[digitalradio] Re: Who Is Where Now : Idea, needs inventor
If I understand the concept correctly, this basically is self-spotting - which I believe to be a great idea. It certainly would not be allowed in contest scenarios, but for most users it would be a wonderful resource. I now use Dave's (AA6YQ) DXLab SpotCollector program for cluster management. It's an excellent program which allows you to view spots using almost any imaginable filter. You can see spots by band, counry, mode, callsign, state, LoTW, etc. - or any combination. A program or online page providing the capabilities of SpotColletor to filter results could really make the Who is Now Where application a powerful - and POPULAR - resource. Instead of spotting someone else, you are just spotting yourself either manually or (preferably) your logging program polls your rig and does it for you. Bob - K3MQ
[digitalradio] Mode of the Day, Spots, Digi activity
Being new to digi modes, the biggest problem I've encountered is finding someone to have a qso with. It's rather difficult to try a new mode (they are all new to me!) without someone to chat with. Being new, I have a real difficult time IDing the signals, and determing the mode and setting. I've joined multiple Yahoo groups and a few clubs. The Feld Hell Club seems quite active, and I worked their Sprint last weekend - great fun! I think having a mode of the day is a great idea ... ESPECIALLY if ops would post their activity on the sked and spot pages. I was really disappointed at the lack of activity on the K3UK DigitalRadio sked page, which is a VERY powerful resource. It's use really fosters extra activity. The same goes for the W6RK spot page and HamSpots.net. Digital spots on the regular web cluster are few and far between (with the exception of PSK and RTTY). IMHO, having a number of ops all working the same digi mode on the same day, AND spotting one another on the cluster AND announcing their activity on the spot/sked pages would have to generate added activity and enthusiasm. If someone is watching DxSpider and they see a bunch of spots all day long for DominoEX, perhaps they'll fire up DM780 and give it a try. Even we we don't get MOTD going, I really hope more digi ops will use the sked spot pages. Not only do they help locatet activity, but they really help in IDing the mode. 73 Bob - K3MQ
[digitalradio] MFTT - questions
I tried out MFTT Sunday. Made a half dozen qsos and have all kinds of questions - hopefully someone else here has used the program before. Lots of activity on the digitalradio sked page. Capuring a pilot signal automatically matches the mode and speed to the originating station? Yes .. No ? If the receiving station captures the cqing station's pilot signal, the cqing station does not need to capture the receiving. Is that correct? I'm thinking that if both capture, one station will constantly be off ... not sure ... I found out real quick you must be absolutely sure that both stations are locked before gertting into longer exchanges. I would be great to get a discussion going on this mode. Lots of new guys checking out the new mode. If you haven't tried - see the lastest QRZ article. Software is a free download and simple. Bob - K3MQ
[digitalradio] Suggestions for digi newbie
Well, I guess I will give the digital modes a try, and need a few suggestions on which modes to try first and which software to use. I've had tons of psk and rtty qsos, but want to try some of the more exotic ones. With the upcoming TARA Skirmish and Feld Hell Sprint, now would be an opportune time. I normally use Winwarbler for psk and rtty. I recently downloaded DM780 and had one Feld Hell qso. From what I can tell, Olivia, MFSK16, JT65A are pretty popular modes, but I will need a different program. At this second, I'm downloading Multipsk. Is that my best bet for a multi-mode digital program? And, are those three modes the ones I should start working with? It would be really great if there is enough activity on each mode to keep me occupied. I'm using a pretty fast computer with plenty of capacity, a good sound card and interface (MicroKeyer) tied to a Icom 756 ProII. I'm familiar with the sked pages. I'd appreciate any feedback.

RE: [digitalradio] Re: Using CTSS on a digipeater?
Your situation is creating for you a huge hidden transmitter problem. Is there anything that says you can't do either of these things: 1) Use a directional antenna - reduce the signal strength from the far-away mountains. Using down-tilt to both better illuminate the valleys close to the digi, and at the same time, reduce the strength of signals on the horizon, by tilting enough to put them well down the main lobe. 2) Move the antenna or digipeater site to a lower location, perhaps where you can gain some benefit from putting the mountain between the digipeater antenna and the most likely interferers 3) Use a different band entirely. It's usually easier to find underutilized frequencies to use for packet, on 222 and 420-450 MHz. A thought associated with hidden transmitters, that we've had huge success with here, but is more complicated, and that's to get a repeater allocation and put up a repeater dedicate for packet communications. This has a number of benefits: 1) No hidden transmitters - at all. Collisions are pretty much non-existant. 2) Everyone connects to everyone direct. No digipeating needed, which instantly doubles your throughput. 3) All fixed operations can use beam antennas for packet because they don't need to be able to hear or talk in multiple directions. Additionally, using beams usually means that if multipath is a problem, you can usually find a direction to point the beam to eliminate the multipath. Movable resources can be equipped with a beam, which can be set up if multipath at that site is a problem. 4) If you don't provide any services on the repeater, like a public BBS, node, or DX Cluster, chances are the repeater won't see a lot of use, meaning it'll be available. The biggest down side is that a repeater is more complicated than a digipeater. There are more pieces to go wrong. But the repeater doesn't need a fancy controller. In fact, using the TNC DCD indicator line (with a KPC 3x set for software DCD) or any other TNC with True DCD, provides the COR line to key the transmitter. Further, the TNC can act as the repeater ID'er - just to send an ID packet every 10 minutes. That has been confirmed to constitute a legal same-mode ID, when the repeater is intended for packet use. If that's an interesting option, I can provide more details. We've had a number of packet repeaters over the years, one of which has been on the air since 1985 or so. The others were on 9600 baud, which is a can of worms I don't recommend, because so few radios that claim to be 9600 baud ready really are not. 73, Bob, KD7NM -Original Message- From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com] On Behalf Of Terry Breitenfeldt Sent: Tuesday, February 24, 2009 8:00 PM To: digitalradio@yahoogroups.com Subject: [digitalradio] Re: Using CTSS on a digipeater? Let me thow out a couple more issues about this problem: 1) The Digi would be located on a hill over 10,000ft high, in an area prone to immense RF inference. Because of its height and the nature of digital signals, I'm concerned that a KPC+ would be overwhelmed hearing multiple signals from hundreds of miles away that might make the TNC unavailable, just when it needs to be available exclusively for ECOM. 2) The purpose of the Digi is specically for RACES traffic and needs to pass ECOM traffic from mobile command posts back to the EOC, for both large and small events. There are other circuts available for non-RACES traffic, so I'm not really concerned that other hams would be excluded from this one Digi. The goal would be to provide the County with a high point that doesn't currently exist. From a technical stand point, I would be concerned if a CTSS tone would be counter productive to the radio reponding quick enough for reliable packet communications. I was also concerned about packet collisions that could be caused by the TNC not hearing all packet traffic on the frequency. I guess the best solution would be choose a packet frequency thats used very rarely by other groups and leave the Digi as a open machine.

Another alternative that can be done remotely is to change the MYDIGI setting to respond to something else, but that's only a short-term fix, since anyone that's monitoring can see the digipeater callsign. Perhaps the most important thing, is if the operation is of a limited period, remember to set operations back to normal operations before shutting operations down, or when the emcomm traffic volume is reduced enough to support normal operations. From a technical perspective, using CTCSS as an operational modifier is a poor solution, for the reason Vince mentioned, and additionally, depending on the TNC and radio combination, having the the CTCSS tone present at the input to the TNC may cause it to make more reception errors than if it's not present. Also, anything that delays the digipeater (especially) from being able to tell that the channel is busy, and that to wait for the channel to clear before transmitting, is going to kill performance and require many more retries than leaving the digipeater open.

RE: [digitalradio] Re: How Can We Push HF Emcomm Messages to the Field?
And further, this thought should be considered as VHF FM, or VHF SSB? In a base/mobile or mobile/mobile environment, SSB on VHF works over much greater distances. With voice communications, VHF SSB benefits from having flutter resulting in the desired signal amplitude going up and down, while the background noise level is held pretty constant, by the AGC in the receiver. FM is opposite in that regard - when the signal gets weak, the background noise level comes up, at least until the squelch closes. In my perception, I seem to be better able to fill in the gaps in syllables when the signal drops out, than when it's filled with noise. VHF SSB also has the benefit of probably not requiring the mobile station to have to take time to set up an antenna. If the mobile station is parked in a null, chances are that moving the vehicle a few inches will change a multipath situation enough to provide good copy. If there's benefit to be had by setting up a portable (v.s. mobile) antenna, putting a VHF omnidirectional stick up 10-20' is a pretty trivial task. While there can be benefit to be had by using horizontal antennas, unless you're into serious weak-signal work, it's not necessary to realize large gains in coverage, even using omni antennas on both ends, using SSB. Digital modes that are designed to work well in weak signal circumstances on HF SSB rigs will similarly work well on weal signal VHF SSB rigs, because the same linear-mode technology is involved. Probably the biggest caveat to that will be frequency accuracy and stability. Radios on a net will need to be well warmed up, or have high stability oscillators, if they are operating unattended, and expected to be able to be received by the sender. I've encouraged those that are working on upgrading our regional hospital network to use the IC-706's that they already have set up for HF pactor, to try VHF pactor using the SSB mode, as a way to gain from the more readily available spectrum, so they don't have to compete for access to the very few frequencies available on HF for digital operations. It'll be interesting to see how they do. 73, Bob, KD7NM -Original Message- From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Howard Z.

HF is the way to go - but both ends of the conversation need NVIS antennas. HF antennas tend to be large, and NVIS needs to be horizontal. I'm not sure there exists an NVIS antenna for a car or truck. Maybe something horizontal can be setup in the bed of a pick up truck? In general HF antennas for vehicles do not perform very well - but they are better than nothing. There are portable NVIS HF antennas available that can be setup rather quickly. Perhaps this is something to be done when he arrives at his destination, and then call the base on HF?

JNOS has KISS as one of its historic interface methods. As long as you have a more modern serial communications chip in the computer you're using (16550-compatible) you should be able to configure it to have adequate communications with the TNC at either 57.6kbps or 115.5kbps, if the TNC supports it. The SV2AGW family of programs may also support that fast serial data rate - I don't have an easy way to check where I'm entering this email. The AGW Packet Engine (AGWPE) definitly also understands how to do KISS. My home Airmail station is using a shim to talk to AGWPE, which is talking to an AEA PK-96 using KISS, which is then interfaced with the radio. Perhaps I've not been watching the list carefully - what over-the-air data rate are you using that makes performing serial communications at 57.6kbps an advantage?

RE: [digitalradio] No Moving Parts (was Fast ARQ Hardware)
I think part of the problem is that in the marketplace, high power PIN diodes that have a carrier lifetime for operation down to 1.5 MHz, and can also handle a couple of hundred watts, don't appear to be easy to find. It's probably one of those problems where the market has moved to higher frequencies, and the parts manufacturers don't mass-manufacture the parts that HF applications need. It's either that, or we need to figure out what the military HF fast-ARQ high-power radios use, then convince the radio manufacturers that they need to use the same design approach. Of course, the military might be using seperate transmit and receive antennas. I know there's at least one company out there that manufactures broad-band wide-dynamic-range low-noise-figure RF-fiberoptic-RF conversion, so the receive antenna can be losslessly connected to the receiver over a distance of miles. That approach eliminates T/R switching.

RE: [digitalradio] Re: Signalink No Good for ARQ Modes
Recollection is that the SignalLink has its own internal VOX circuit, so can be independent of the VOX settings of the rig - except if the user makes the mistake of turning VOX on in their rig, and the rig has a longer delay time than the SignalLink does - which is likely. Either way, I cringed when I heard that the SignalLink uses VOX, with no direct control option.

This because due to sound card buffers, the obligation to work even with slow computers, and due to slow modulation, it is introduced big margins (several hundreds of ms or even seconds depending of the mode or the number of repeaters used in Pax, for example). So this delay is not critical. And as Rick said, it is a positive point about asynchronous ARQ modes which are flexible. Moreover they are economical as they transmitted only when requested and not everytime (transmitting padding characters). However, for quick ARQ modes (as RFSM2400 or 110A) it is certainly an other story, as the margins might be very low...and, moreover, I'm not very sure that the VOX delay is really constant... It might depend on a filter associated with a threshold. The delay with which the threshold will be switched will depend on the sound level at the input. The best is the direct switching from the serial port, then the Cat system and afterwards the VOX system. 73 Patrick - Original Message - From: expeditionradio [EMAIL PROTECTED] To: digitalradio@yahoogroups.com Sent: Tuesday, August 26, 2008 8:26 PM Subject: [digitalradio] Re: Signalink No Good for ARQ Modes Sholto Fisher wrote: I can't believe it makes any significant difference at least for ALE400 FAE.

Re: [digitalradio] Newbie ? PDA instead of computer?
Hi Mike, I suspect that the USB port on your phone will not be useful for using the phone to control anything. That's because most USB devices are not configurable to act as USB host devices. Most likely, your phone is in the same category - it's able to be supported by a host computer, as a client, but not able to be configured itself to act as a host. If the phone is able to be configured as a host, then you could potentially do serial port control of a TNC, or the PTT signal of a Rigblaster, but only if the phone also knows how to be the host for a serial port USB adapter. Using the sound ports on the phone are probably the more likely possible means of connection. The use of VOX for EMCOMM generally is intended to apply to actual live-microphone circumstances, which if you have the SignalLink plugged into the speaker/mic connector on the radio, probably doesn't apply, since it the radio will still be in PTT mode, and the SignalLink will generate the PTT signal. If you elected to use the internal VOX in the radio, there are a couple of ramifications: One is that you'd want to make sure that plugging connectors into the speaker/mic jacks on the radio disables the radion's internal microphone. You would want to test it to make sure that with the radio set for VOX, that talking loudly near it doesn't trigger the transmitter. The other is that the VOX delay has to be minimized as much as possible, if you're going to be using packet. Further, for other ARQ modes, the VOX will almost assuredly be too slow - it's unlikely that the radio itself will handle T/R switching times, with or without VOX. Hope that gives you an overview of what are likely hurdles to overcome, or that may not be possible to overcome. 73, Bob, KD7NM On Thursday 31 July 2008 09:38:04 Mike Souza wrote: Hello, I’m just starting to explore digital radio and have some basic questions.

Re: [digitalradio] Diagnosing issues with dropped PC
One of the other things I'd do, sooner rather than later, is to remove the hard drive from that PC, and either install it in another PC (like the ham shack machine) or in a USB hard drive enclosure, and see if the drive is recognized at all on the other PC. If it is, then copy over to the other PC everything on it that you consider not replaceable, while you can. The drive may not be dead, but if it's in any way physically damaged, it's only going to get worse, never better, and it's demise will probably happen pretty quickly.

RE: [digitalradio] Open wire feed line length
Where practical and available, instead of using a split-core ferrites, use a ferrite toroid. The split core will never achieve the level of magnetic coupling between the two halves that the toroid will, with its continuous magnetic structure, and all else being equal, that makes the toroid a better supressor. Adding more turns through either one helps two, as the inductance scales by the square of the number of turns. The control cable and coax for my screwdriver HF mobile antenna went to the front bumper by way of the engine compartment. By wrapping several turns of each cable through a ferrite toroid, one commonly used for HF baluns, I was able to essentially eliminate the ignition system RFI and the electrical noise from the screwdriver antenna, located inside the antenna. It also allowed me to operate using this antenna on 6M, something it was designed to do, without having the RF overload the engine CPU or sensors. Further, on 20M your ground wire is close to a quarter wavelength from ground - which causes it to create a fairly high impedance against ground. You might be able to benefit from a tuned ground, or if possible, run 1 or 2 1/4 wave counterpoise wires from the tuner, off along the baseboards of the room, to create a lower impedance RF at the tuner, and provide a path for the stray 20M RF currents that's not by way of your radio coax and cables to the computer, etc. MFJ makes an artificial ground that might be employed if none of these other things works out. I'd try to find one to borrow before pony up cash for one though. 73, Bob, KD7NM _ From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Dave AA6YQ Sent: Wednesday, July 02, 2008 2:39 PM To: digitalradio@yahoogroups.com Subject: RE: [digitalradio] Open wire feed line length I have used that multiband antenna configuration both at my home station (140' doublet, 450 ohm ladder line, 1500 watts) and when travelling (70' doublet, 300 ohm TV twinlead, 100 watts).

MFJ recently introduced a balanced tuner; I haven't examined its schematic, but it sure looks like a Johnson Matchbox on the outside. 2. If you use an unbalanced tuner and an external balun, minimize the unbalanced connection length between the tuner and balun. My travel tuner is a small MFJ unit with a built-in balun, and it works very well 3. I almost always end up iteratively trimming the feedline length to enable the tuner to find a good match on all bands; I don't know of any effective formula or rule of thumb that would eliminate this process, so I just start with a lot more feedline than is physically needed and lop off 3' at a time until the tuner is happy everywhere.

RE: [digitalradio] Re: newbie wanting to make first packet contact
Hi Doug, Before you commit a lot of effort to learning about how to use dumb digipeating, i.e. using via, try to find out if there are still operational nodes in your area. These are generally much more efficient at moving traffic, because they are less dependent on every single packet transmission being received and passed along, through the potentially several digipeaters. Nodes work by first accepting a connection from your station, then you commmanding them to either connect to another node, or to a destination station. They maintain internal tables of the means to reach other nodes, and unless disabled, can be commanded to list the other network nodes that they know how to reach. When you command a node to connect to another station, be it a node or an end user, the node manages that connection as a separate AX.25 connection from the one it's maintaining for you - so any retries happen without direct digipeating - which reduces the retry interval, and greatly enhances the reliability of the data transfer. In the hey day of packet, some nodes would know how to reach as many as 100 other nodes. And by using dedicated linking channels, the end user you reach might not be on the same frequency as you are. There's less interested in creating and maintaining packet networks these days, probably as a result of the ease and ubiquity of the internet, at least as one significant factor. I was pretty involved with creating the packet network that started from the Seattle area, and eventually reached into British Columbia, SW Oregon, and as far east as the Rockies, or so, in Montana. On that network, one of the operating precepts was that user access nodes be on different frequencies, so that they didn't hear (and hence interfere with) other stations at a distance. A backbone was created to tie all of the user access nodes together. We also made good use of repeaters for packet - they help in that everyone can hear everyone else, to know when the channel is busy, and allows everyone to use a beam, to hit the repeater with the best signal possible. We did this at 1200 baud as well as 9600 baud. Then we did some of these projects all over again, as we moved to using TCP/IP over AX.25 - uaing automated routing based on the RIP protocol, and having as many as 20 IP lans in Western Washington. 'Twas a fun time. Now packet here is mostly used by Emergency Communications support activities. 73, Bob, KD7NM -Original Message- From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of wizhippo Sent: Wednesday, June 18, 2008 2:41 PM To: digitalradio@yahoogroups.com Subject: [digitalradio] Re: newbie wanting to make first packet contact Thank you.

On the North American continent, the APRS 2-meter frequency is 144.390 MHz. APRS stations don't operate in the connected mode, so you're not going to connect to other users. However with appropriate software (and there are several APRS-specific programs out there) you can exchange one-line messages with some stations you see.

RE: [digitalradio] Re: Microphone putting audio into PSK transmissions
Hi Dave, Rather than switching all eight lines (so you might be able to use a cheaper and easier to wire switch) I'd look at which lines are used for what purpose, and make some intellegent decisions about what you're using, and what needs to be switched. For example, you shouldn't need to switch any ground connections. You probably don't need to switch the PTT connection, though if you key the wrong mike, (except on AM/FM) you won't get any power output. If you don't use the up/down functions then they don't need to be connected. If you can get your list of required connections down to 3 or 4, depending on the switch, it could be a single-deck switch. Or you may only find a switch with 12 (or 6) positions, but the ability to put a stop in the switch, to limit rotation. That switch will have more decks, with some (to many) terminals unused. You'll also want to consider whether RF suppression will be needed - such as if you use a plastic enclosure, which (unless it's sprayed with shielding paint) will lack shielding, and could create an RF feedback problem for you. Just things to consider.

[digitalradio] The sorry state of VHF/UHF Packet
Hello all, I came across a box of old Maxon DM-0515 / 0530 data radios and am going to donate them to my University radio club, where they will be recrystalled and we'll start our local net. While talking to local packeteers and researching packet on the Internet, I have become quite dismayed at the state of the art and the state of the community. There seems to be lots of acrimony. There seems to be lots of decay and a general reduction in the site and number of packet networks on VHF/UHF. Much of the blame for this decline has been blamed on the rise of the Internet. While the rise of the Internet has changed the way people might think of the utility of packet radio, I don't think that this is the only reason for its decline. A survey of web sites and software shows the sorry state of affairs. The hits that Google returns for packet radio are so out of date, many have not been updated since the late 90s. Software is another big problem. I am a Linux user, and I insist that software I use be open source. Much of the software out there has become Microsoft-only or Microsoft-centric, and closed source. This simply will not do. Closed source is 'appliance operator' software. It does not allow, never mind encourage, and experimentation or innovation. This results in packet radio technology being stale, stuck in the last millenium. We need to reinvigorate the digital radio experimenters community on VHF and UHF, much as the way PSK31 reinvigorated HF digital radio, and Amateur Radio as a whole. This is not to say we need a copy of PSK31 for the higher bands, but some manner of progress. We need to identify the technical issues facing packet, and address them. We need open-source software, inexpensive hardware, and good performance. Perhaps we need to make a complete break with the past. I'd like to think we can continue to support existing protocols while at the same time advancing the art of radio, but that we would re-examine everything from modulation schemes and right on up the stack to address modern needs and abilities. I have to admit, I have been out of the packet scene for some time. I got caught up in WiFi networks, and I am still heavily involved in that area. Perhaps there are areas of progress that I have missed. If that's the case, please inform me, and also attempt to make these projects more visible. 73, Bob N1YRK
[digitalradio] DM780 and MFSK16
When using Simon's DM780 for MFSK16, I get a lot of question marks ? in the received text display. If I quickly switch to MultiPSK I don't get the question marks. It's kind of a pain. I assume the question mark is displayed because some unknown character has been received. Is there any way of turning this function off? Thanks--- Bob Christenson (WU9Q) Rock Island, IL
[digitalradio] Monitor interference
Hi Folks, I just found this groupa few weeks ago and have just been lurking. I have a Buxcomm interface on the way to my QTH, It may be here tomorrow or Tuesday. My question is I am getting some noise/interference from my monitor (Regular CRT, not lcd flatscreen) on my radio. The radio is a Yeasu FT-101Z. IS there any fiz for this interference problem ? Also, do the new LCD flat screen monitors have the same problem ?? Thanks Bob KC9GMN Clinton, Ill

I think I can set it to do aggressive deep search on a narrow freq. window. I am still not clear on how having freeze checked vs. unchecked works. Should I normally listen with it unchecked to search the larger subband? If it is unchecked, does the green bar in SpecJT make any difference? Does clicking somewhere in SpecJT or the other graph actually set the real transmit frequency? Sorry to be asking basic questions but it doesn't seem clear from the documentation and guides.

[digitalradio] RigExpert Plus and winDRM/Easypal_Lite
Has anyone had any luck getting either of these programs to work with RigExpert Plus?? I can receive fine, but have tried all combinations of the tx input and while the PTT works fine, there is nothing inputted. I have not yet tried a mic into the input of the sound card as I am just trying to get the programs to transmit a tune or in the case of Easy Pal, a BSR. There is simply no output even though the programs key the PTT without a problem. I could, of course, hook up the sound card in/out to the rig, but am curious why the RigExpert doesn't seem to work. I use it without a problem on PSK and other digital modes. .Bob

[digitalradio] Re: Those microphone thingies in digital bands
Andy, Here in Singapore the government has historically only allowed us to use 7.000 to 7.100 on 40 m. Interestingly, I found out that the CW vs. SSB sub-bands are not mandated by the government. They don't care about that. So we just go by the IARU Region 3 Bandplan that says the Phone sub-band starts at 7.030. Just a while ago the Singapore government allowed us to go up to 7.200, using 7.100 to 7.200 as a secondary service as long as we stayed off 7.135, 7.160 and 7.170. During the ARRL DX SBB contest I could therefore have finally worked a US station simplex in that part of the band. Funny though, the only ones I worked on 40m were the ones I worked as they worked split, listening for the Japanese stations in the 7.050 to 7.100 area since the Japanese stations still cannot go above 7.100.

The above circuit should work on your FT-101. The important thing is that the rig should not drift. While a jump of 50 Hz is OK on SSB, it will cause loss of signal on digital. You will be able to spot a drifting problem by watching the signals on the waterfall. I can send you a 4N35 if you can't source one locally; I'm fairly certain I have some spares.

RE: [digitalradio] Re: PK-232MBX
Is it the cable or is it the PK?? I am writing this because Timewave is closed, they send their people home at 4:30 their time. I found out the other day when I had them on the phone asking questions about this PK-232MBX concerning upgrades and cables. If anyone here can help it would be most appreciated. Any constructive suggestions would be welcome. I understood Timewave to tell me I needed a modem cable to connect the PK to the computer. They offered to sell me a set of cables for 30.00 but I don't have the money to spend on anything but bills and sons right now. So, I tried to make my own MODEM cable (like a good Ham) by cutting two cables which gave me a male db25 on one end and a female db9 on the other. I connected the cable to the computer com1 serial connector and to the db25 connector on the PK-232MBX. The MBX starts up does its self test and then goes into wait mode awaiting its next command, with the BAUDOT light lite, but the application I am using MODEMSWITCH says it can not find the PK-232 on any of the com ports. So I have now bought an AT compatible modem cable off of ebay with the proper connectors. I need to make sure it is not the cable I made causing the problem. Here was the procedure I used: I looked up serial modem cable wiring. I made copious notes and drawings of the wiring configuration and started to work. 9 PIN 25PIN 1 8 2 3 3 2 4 20 5 7 6 6 7 4 8 5 9 N/C I found an old parallel printer cable with a db25 and one of those funny looking parallel printer connectors on it. I cut off the printer connector and left the db25 and stripped the rubber back and then separating out all of the wire in tact on the db25. I rang out the cable with the db25 on it until I had the wires going to the correct pin numbers for the modem wiring. I then cut the end off of a cable that had the two 9 pin connectors - one on each end of different genders. I picked the gender that matched the db9 connector on the back of the computer and then rang that cable out pin to pin. I then matched the wires and soldered them together according to my notes and drawings of what I found for serial modem cable on the internet. I heat shrinked them to avoid shorting. 9 PIN 25PIN 1 8 2 3 3 2 4 20 5 7 6 6 7 4 8 5 9 N/C For some reason it isn't working but it seems that the PAKRATT is because it goes through all of its diagnostics and all is well. I have since rang out the cable again and corrected all errors but it still doesn't work, I have again rang out the cable and the cable rings true this time (double/triple checked) Any ideas how to test this system (Is it the cable or is it the PK??) 73 fer nw es gud DX, QSL VIA: BUR, LotW, e-QSL Bob AD5VJ Old calls: WY5L/KH3-KE5CTY-N5IET http://www.ad5vj.com/ Member: CTDXCC, NTCC, STXDXCC FISTS: # 12637, SKCC# 2369 10X# 37210, FP#-1141 SMIRK#-5177, RARS #-149 -Original Message- From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of earicci Sent: Saturday, January 20, 2007 3:37 PM To: digitalradio@yahoogroups.com Subject: [digitalradio] Re: PK-232MBX Dave: They sell any cable you need, and will even build custom if you need.

In addition, the Order resolves a petition filed by the American Radio Relay League, Inc. (ARRL) for partial reconsideration of an FCC Order on amateur service rules released on October 10, 2006. The current amateur service operator license structure contains three classes of amateur radio operator licenses: Technician Class, General Class, and Amateur Extra Class. General Class and Amateur Extra Class licensees are permitted to operate in Amateur bands below 30 MHz, while the introductory Technician Class licensees are only permitted to operate in bands above 30 MHz. Prior to today's action, the FCC, in accordance with international radio regulations, required applicants for General Class and Amateur Extra Class operator licenses to pass a five words-per-minute Morse code examination. Today's Order eliminates that requirement for General and Amateur Extra licensees. This change reflects revisions to international radio regulations made at the International Telecommunication Union's 2003 World Radio Conference (WRC-03), which authorized each country to determine whether to require that individuals demonstrate Morse code proficiency in order to qualify for an amateur radio license with transmitting privileges on frequencies below 30 MHz. This change eliminates an unnecessary regulatory burden that may discourage current amateur radio operators from advancing their skills and participating more fully in the benefits of amateur radio. Today's Order also revises the operating privileges for Technician Class licensees by eliminating a disparity in the operating privileges for the Technician Class and Technician Plus Class licensees. Technician Class licensees are authorized operating privileges on all amateur frequencies above 30 MHz. The Technician Plus Class license, which is an operator license class that existed prior the FCC's simplification of the amateur license structure in 1999 and was grandfathered after that time, authorized operating privileges on all amateur frequencies above 30 MHz, as well as frequency segments in four HF bands (below 30 MHz) after the successful completion of a Morse code examination. With today's elimination of the Morse code exam requirements, the FCC concluded that the disparity between the operating privileges of Technician Class licensees and Technician Plus Class licensees should not be retained. Therefore, the FCC, in today's action, afforded Technician and Technician Plus licensees identical operating privileges. Finally, today's Order resolved a petition filed by the ARRL for partial reconsideration of an FCC Order released on October 10, 2006 (FCC 06-149). In this Order, the FCC authorized amateur stations to transmit voice communications on additional frequencies in certain amateur service bands, including the 75 meter (m) band, which is authorized only for certain wideband voice and image communications. The ARRL argued that the 75 m band should not have been expanded below 3635 kHz, in order to protect automatically controlled digital stations operating in the 3620-3635 kHz portion of the 80 m band. The FCC concluded that these stations can be protected by providing alternate spectrum in the 3585-3600 kHz frequency segment.

[digitalradio] ARRL Bulletin and Code Practice Frequencies
They've only been using those times and frequencies for about 50 (Fifty) years and all over the world people wait for them to start transmitting to practice their Morse reception under realistic conditions. I would think that virtually every ham in the world knows these times and frequencies. So why would you have to be deliberately on these frequencies when the ARRL begins transmission? Simply to be obnoxious? Surely there is room to move and surely you don't deliberately schedule a contact on these frequencies and at these times?

I've been following the list now for some months. I'm an OOT first licensed in 1960. And I am really interested in digital communication as I've earned my living up to now (retiring) as an EE working with networks. My question is: Does anyone ever ask: Do we need another digital Mode? It seems a new one is on the list about every 14 days. It takes me about 30 minutes to figure out which mode I should be decoding!! I am seeing mode proliferation that looks like it's being done to say Look a new mode and it does something better than another mode, ...but not everything, some things it does worse... It's like the feature proliferation in mobile phones, Geez I just want to telephone with the thing and none of them can do as good a job as a real camera or a real MP3 player. But they are more expensive and if you use the features to send pictures etc. the provider is making a LOT of money. 73, Bob DJ0MBC/WU5T Yahoo!

[digitalradio] SCS PACTOR New for Ham.Radio in Friedrichshafen
Here is the announcement and I have nothing to do with SCS except a happy user: Dear PACTOR friends! Just like every year we want to invite you to visit us at the Ham-Radio exhibition in Friedrichshafen, in the south of Germany. The show takes place from 23th until 26th of June. Our booth is located in hall 1 and has the number 432. As always we have a new firmware for all our PTC-IIxxx modems with us, more on that item below. Additionally we are going to introduce two new PTC modems, which are the PTC-IIusb and the PTC-IInet. The PTC-IIusb: -- As the name indicates, with this product we want to accommodate the increasing demand for a modem with direct USB connection to the PC. The external V24/USB converter is with this not required any more. With its features and functions, the PTC-IIusb finds its place between the PTC-IIex and the PTC-IIpro. Like the PTC-IIex, it is a single port unit with just one radio connector, which is capable of all known modes alternatively, but not simultaneously. But just like the PTC-IIpro, the PTC-IIusb has a full featured transceiver control port. Thus, with this unit it is possible to control a transceiver from the USB port of a PC. The size of the housing is the same as the PTC-IIpro. In opposite to all the other modems we refrained from backing up the memory with a battery because this has sometimes created some trouble, especially under maritime operating conditions. Finally, with our new modems we have the power switch on the frontpanel, which was also asked for by many users. The PTC-IInet: -- The PTC-IInet is a combination of a PACTOR modem (with transceiver control) and a Linux-PC, where both find their place together in a PTC-IIpro sized case. The PTC-IInet has a network connection (Ethernet 10/100) and can with this directly be connected to a router. If that router is connected to the Internet (e.g. via DSL- or cable-modem) then the PTC-IInet is also online this way. When the PTC-IInet receives a connect from the outside, it serves as a gateway into the Internet for that distant station. This function is called PACTOR-IP-Bridge (PIB) and works similar to WLAN, but with the advantage of a very large range of coverage and the disadvantage of narrow bandwidth. The PTC-IInet is by default delivered with PACTOR-III and can be configured with a standard webbrowser, which means that it has a build-in webserver. It is the same method how routers and WLAN accesspoints are configured, so this procedure can be assumed as well known. Another interesting viewpoint of having a networking PACTOR modem device with transceiver control capability is the fact, that with transceivers can be controlled via the Internet this way from any point of the planet. The PTC-IInet largely supports that feature with its web interface. The web interface also supports automated updates of the firmware and Linux kernel via the Internet. With a simple click on a button, the PTC-IInet connects to the SCS Internet server, looks for updates and installs them automatically, if available. If anybody wants to play with the web interface of a real PTC-IInet, he may use the link to one of them here at the SCS facilities: http://dl1zam.dyndns.org. I'm really curious how many simultaneous connections it can serve :-) A detailed article about the PIB with the PTC-IInet is available here: http://www.scs-ptc.com/download/pib_review_eng.pdf New Firmware 3.6: - The version 3.6 firmware considerably increases the functionality: For the first time the PTC firmware supports Automatic Position Reporting System as stand alone service. A PTC can be used as a position Tracker. The generated datagram is APRS compatible. Version 3.6 offers a further important new feature, an innovative, robust modulation mode for HF-Packet-Radio (HF-PR). This is also the ideal method to transfer position data with high reliability via shortwave. As a special feature for all the variants of Robust PR, a completely new synchronizations algorithm with catch properties that were not possible before has been implemented. Frequency deviations of up to ±250 Hz are immediately recognized and compensated without any loss of sensitivity, and this with signals that are buried deep in the noise. The new modulation method (Robust Packet-Radio) is available for free for the PTC-IIex and PTC-IIusb. For the PTC-II and PTC-IIpro a new DSP-Modem-II (plug in module) will be available from SCS as of June 2005. The new DSP-Modem certainly offers all the past PR-modulation modes (300-19200 Bd). Only the PTC-IIe is unfortunately not upgradeable for Robust-PR. IMPORTANT for the (old) PTC-II The firmware (firmware file profi36.pt2) will only be started by the PTC-II when the PTC-II is equipped with 2 MB of RAM. The PTC-II is upgradable to 2 MB of RAM, the price for that upgrade has been reduced to the half to make the decision easier. Further

If you are able to provide me with two documented instances of when the ARRL took the initiative to lobby for a proposed change in digital regs prior to year 1990, I would be happy. I am notfrom Missouri, but I seek proof that ARRL lobbying resulted in permission to use digital/data modes. Perhaps such changes have come about after my termination of ARRL membership. When I visit the local library and read QST, I might have missed something since 1991. I do recall the so-called Incentive Licensing initiative in the late 1960s, and the introduction of no-code licensing, sometime around 1983 I think. However, that does not seem to be saving bacon for anyone in the Ham community. And, then there was something about needing a segment for International HF packet stations to operate; the result being FCC's refusal to channelize HF spectrum and an introduction of a gentleman's agreement to reduce the RTTY sub band by 10 kilohertz. That was sometime prior to my personal decision to leave the ARRL club. When an ARRL Division Director stated to me personally at the 1991 Convention meeting that there are no Gentlemen operating on 20 meters I decided to decline future renewal in the ARRL club membership. At the time of PSK31 introduction (~~1999), I found myself at the library reading a QST article that seemed to want to put an end to the (obsolete) RTTY mode of operation.

RE: [digitalradio] Automated stations and W1AW
As far as I know the ARRL station has been using the same frequencies for several decades (40 years or so)!!! So although they do not have a right to the frequency, by convention we all know that's where they transmit so we try to leave the frequency open for them. They do not frequency hop or where would we listen? Or weren't you aware of this? 73, Bob DJ0MBC/WU5T -Original Message- From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Andrew J.

As long as the automated station does not transmit on a busy channel, nothing is really wasted. It is identical to any other human operator calling CQ. Eventually, we will may have some ALE modes that will increase the efficiency of HF digital connections and reduce the interference problems with quickly sounding out the channel. Not a great deal different from a CW QRL? The K3UK DIGITAL MODES SPOTTING CLUSTER AT telnet://208.15.25.196/ Yahoo!

I would seriously doubt that every time you talk on the radio you limit your discussion to just technical matters. I'm sure you've mentioned the weather, talked about your family, mentioned a great movie you saw or book you readand spoken of other ham friends. Once again this has missed the mark. How about phone patches for military personnel that are stationed abroad? We won't let them talk to family and friends anymore? Eric, KB6YNO -- Original message -- Mike hits the point . Ham radio is not an American radio service limited to the borders of the lower 48s Canadian regulation (Iknow third world countries don't count) but nevertheless Canadian Regs state that Ham communications should be of technical nature or not warrant the use of commercial means... in past times autopatch on the vhf was tollerated before de advent of cellular phone... etc.. Sending traffic that could and should be sent on the net or phone lines should be reserved to the net and phonelines,, And even if ham radio can be of invaluable help in emergencies and disasters situations no one should hijack world wide international requencies on the pretention that a system mode or whatever is prepairing 7 days a week 24 hours a day for some eventual local or regional emergency... And finaly who cares if 1% of stations carry 75% of illegetimate trafic...

Mike's message will not induce the FCC to eliminate the ham bands, nor will it induce the IRS to begin taxing amateur transmissions. Surely, you could find a less intimidating way of providing a correction. For example, let me point out to you that the QRM discussions here have not been limited to Pactor 3. The use of any Pactor protocol in semi-automatic operation causes QRM; these protocols lack the busy detectors that would enable station automation software like Winlink to refrain from responding to a request when the frequency is already in use. The QRM in question is not supposed; I have personally been QRM'd by Pactor signals on several occasions, as have many other users here. It would be nice if you and Steve K4CJX would stop pretending that this QRM doesn't occur, or that it only affects PSK operators using panoramic reception. When you deny reality, your credibility
