Re: [digitalradio] Disinformation about ALE by N5PVL Re: Getting serious about ALE / LID factor
Bonnie, sitting on the side, I see both sides of this. You, on one hand, always appear to be pushing expansion of new modes (which is good in some respect - that's what makes for advancements in science), but on the other hand, you appear to always want to push other users away, with broader bands, higher speeds, and be dammed with any mode you do not want to use. I haven't been reading much of your output this past year, because I truly got tired of seeing that, particularly when you seem to just ignore the expense of present users. I would like to remind you that many of us have, over and over, been the victim of some digital mode popping up on a busy frequency, and driving us off. You could make a great contribution to acceptance of these new modes, if you would just step up and agree that it happens, and that the contributors (program writers) should write in for busy frequency checking of the bands, before transmitting their own signal. We already require this of CW/SSB/RTTY/PSK etc. users. Why should a user of these higher-newer modes not be held to the same requirements? With your knowledge and experience you can make a great contribution here, but really need to help cut back on the push to allow interference to others, for advancement to techonology. Please give this some thought. And by the way, contesters are a very main reason for advancement of technology in antennas and hardware - and they have been here a long time. ( I agree, they too should be limited to set sub-bands within the spectrum, but that is unlikely to happen because the sponsors are quite unwilling to accept the facts of their interference to other users).

So instead of mechanical switches, I always use relays. I also convert all connectors to D-subminiature or 3 conductor 3.5 mm stereo jacks. So what I would do is buy a cable with a 13 pin DIN plug on it and wire a DB-25 to the other end. The box would have a DB-25 and two DE-9's. The DE-9's would connect to the ancillary equipment (assuming that no individual piece of equipment needs more than 9 of the 13 pins). The control for the relay bank would be via a 3 conductor 3.5 mm jack. I can get cheap 3.5 mm patch cables and D-sub cables at the swap meet. Rick N6RK

I'm no fan of the way in which many contest stations seem to use, and abuse, the band plans, but neither am I a fan of digital modes that, maybe unintentionally at times, trample upon other legitimate users of the bands either... Unfortunately, legislating against either abuse is both unlikely to work and probably impossible to implement. Personally, I would like the organisers of the various contests to enforce their own rules against persistent offenders. However, experience over many years suggests that they either will not, or dare not, do this, which begs the question why have the rules? I would prefer that the DX community did not trample on top of people at times, and listen before they transmitted and I would like the Band Police to not transmit over the top of what they think should, or should not, be done on a frequency. I would also like the ALE and digital community to recognise that they share the bands with everyone else and are not immune from the 'listen before use' rule either. However, these are just my 'would like to have' and are obviously not shared by the majority, as they do not happen. Dave (G0DJA)

[digitalradio] Moderator comments : Listen-Don't listen
Before we go down the path of debating listen first or not. I will remind folks that most of the argument has been stated before. Aside from the legalities of the issue, there are camps that strongly advocate that every hams should also listen first and not transmit if the frequency is busy, and those that feel some modes have such short initial identifying bursts that listening first is not necessary , and perhaps antiquated. I think we should acknowledge both viewpoints, without dragging the issue on and on. What I do feel needs pointing out is that if you take the first position, that one should always check a frequency and inquire if it is free, logical would dictate that this applies to all aspects of hams radio including contests. A contester that calls CQ Contest without QRL is as guilty as an ALE or Packet station. Since I am a contester, I might argue that although the frequency is crowed, I think my signal can fit next to others without undue QRM. That might not be that much different than a Propnet station that fires up 32 hz away from me. I may think it annoying but they might feel I should be able to operate with a close neighbour. Feel free to share your opinion on the matter but do so with respect for other opinions. In the scheme of things , whether one believes in QRL first or not, does not make the person with contrary views in to a evil dastardly person. We just differ. Andy K3UK

Re: [digitalradio] Moderator comments : Listen-Don't listen
Unattended stations make no attempt to share at all, but assume the frequency is theirs whenever they want it, and actually they never know if it were clear or not, as they can just automatically transmit again until they are successful. This undermines the principle of shared frequencies, which is what Charles was trying to point out. Skip KH6TY but not ALE all stations (I can't speak for Propnet) are unattended.. I was in my shack at each sounding yesterday. Also, my ALE software pauses a scan and suddenly says listening for a few seconds before it transmits. It rarely prevents a transmit if the frequency is busy, but my brain causes a quick glance at the waterfall when I hear a scan stop (my rig makes a noise) and I can simply stop a transmit if the frequency is busy. The interesting thing is that the ALE data frequencies rarely busy . As I type this there is a Pactor station squawking away about 1500 Hz away but I went HOURS yesterday without having to stop an ALE transmit . Andy K3UK

[digitalradio] Re: Moderator comments : Listen-Don't listen
Bonnie your argument is some contesters and DXers QRM ongoing QSOs, so therefore its ok for ALL unattended stations to QRM ongoing QSOs. This is poor engineering; when we automate things, the idea is to automate good practice, not bad practice. You don't see anyone designing autopilots that can become disoriented, do you? And by the way, most DXers in a pileup do not seek to QRM each other, as that guarantees they won't be clearly heard by the DX -- even when using a powerful station. The idea is to seek clear spots in the pileup into which to drop your call so you can more likely be heard by the DX. This is particularly true in digital mode pileups. 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, expeditionradio expeditionra...@... wrote: Skip KH6TY wrote: A contester who calls CQ Contest is usually doing it on a frequency that is clear at the moment Hi Skip, What planet do you live on? :) I want to live there in that mythical land, where all contesters get to transmit on clear frequencies.

During an emergency, no one has a problem ceding frequencies to emcomm stations; its like heading for the shoulder when you hear an ambulance while driving. When there's no emergency underway, however, the automatic bands are available to all amateur stations, not just unattended stations.

Re: [digitalradio] Re: HF International Automatic Subbands
I agree 100% - and I operate an automated Packet station in one of the sub-bands. Fairly often, on weekends I see a good deal of RTTY contest activity there, and the RTTY guys have proven to be good nieghbors. I use MixW as an HF Packet modem, which allows me to open up a second or third window in RTTY mode and read the mail during the contests. Seeing how much fun those guys have, I've decided that if I ever get into contesting, it will be in RTTY mode first. 73 DE Charles Brabham, N5PVL Prefer to use radio for your amateur radio communications? - Stop by at HamRadioNet.Org ! http://www.hamradionet.org - Original Message - From: aa6yq To: digitalradio@yahoogroups.com Sent: Monday, November 23, 2009 7:34 PM Subject: [digitalradio] Re: HF International Automatic Subbands During an emergency, no one has a problem ceding frequencies to emcomm stations; its like heading for the shoulder when you hear an ambulance while driving.

[digitalradio] Dx pile ups..

Not ALL DXers , but the vast majority are doing what Bonnie describes when responding to a QRZ. If I hear P5DX QRZ?, then I hear November Seven Delta... starting a call and throw in Kilo Three Uniform Kilo on top of the 7 station (Danny) , Bonnie is correct that I have QRM'd him. I guess the difference is that this is accepted and actually encouraged. I still remember my utter shock when a new ham reading the ARRL handbook about DXing, and how a DX station would listen on incrementally different QRG and NOT tell you exactly where. The book explained that the art of DXing was to determine the DX station's methods and skillfully figure out where he would be listening. In Bonnie's context, this would be encouraging lots of QRM . Skip's earlier point would be that this still differs from unattendned transmissions but I think Bonnie's point is that the result is not that much difference.

[digitalradio] Re: HF International Automatic Subbands
My recollection is that the discussions leading to the creation of the automatic sub-bands included expressions of the same concerns that continue to surface here: an operator in California who activates an unattended station in Denver can't know that the unattended station will QRM an ongoing QSO between stations in Chicago and Dallas because the operator in California hears neither of those stations. The FCC's solution to this problem was to 1. remind amateurs that they are expected to solve technical problems like this one 2. confine automatic operation above a specified baud rate to the automatic sub-bands As has been pointed out here too many times, viable busy frequency detectors have indeed been developed, but they have unfortunately not been widely deployed. Perhaps Winmor will user in a new age of enlightenment. Your ALE setup is automatic, but its only unattended if its operating while you aren't in control. 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, Andy obrien k3uka...@... wrote: When there's no emergency underway, however, the automatic bands are available to all amateur stations, not just unattended stations.

RE: [digitalradio] Dx pile ups..
In a DX pileup, calling on the same frequency that someone else is calling generally results in neither of you getting through, particularly if you are using a digital mode. The idea is to 1. understand the range of frequencies in which the DX station is listening 2. crop your callsign into a hole in this range so that it will more likely be heard clearly In lighter pileups, the DX station may exhibit a pattern -- .e.g. moving up 500 hz after each RTTY QSO. Astute DXers learn this pattern, anticipate the next frequency, and call there. However, this only works when there aren't too many astute DXers. Spectrum scopes have made it much easier to rapidly detect such patterns, turning the anticipated next frequency into a zoo. As a result, many DX stations have abandoned the pattern method; instead, they randomly look for stations in the clear across the range in which they are operating. No DXer should participate in a pileup if doing so would QRM an ongoing QSO. In my experience, politely asking the participants in the ongoing QSO to move almost always yields a polite and positive response. 73, Dave, AA6YQ -Original Message- From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com]on Behalf Of obrienaj Sent: Monday, November 23, 2009 9:17 PM To: digitalradio@yahoogroups.com Subject: [digitalradio] Dx pile ups..

[digitalradio] Digital busy detect
Packet radio gets by with a simple carrier detect, PACTOR can only detect other PACTOR stations, and from what I can tell, ALE has no busy detection at all. Several years ago I took a serious look at automated busy detection, and always ran across the same stone wall: A more sophisticated busy detect that can usually tell the difference between noise and a human activity like speech or digital transmissions is possible - BUT - only after the software has a fairly long audio sample to work with, and can look back upon that sample. It can't do this instantly, or even very quickly unless you have a supercomputer to work with. If it listens to a long sample and a new signal comes in toward the end of that sample, that new signal may or may not end up being identified. This is a terrible thing to have to report, but Packet's carrier detect is the most effective and sophisticated automatic signal detection scheme we currently have at our disposal. - It detects more kinds of activity *right then* than anything else that hams are currently using. There are lots of signals that carrier detect will not detect - but it is still the best thing out there, that can automatically detect and act in ( more or less ) real-time. The human ear works better, detecting signal intelligence and differentiating it from noise far better than any automated detection system. Period. Better still is the human eye, looking at a properly set up waterfall display that will show you recognizable patterns in the waterfall image that you may not be able to register just by listening. One thing to ponder is why carrier detect, developed over twenty-five years ago is not utilized by PACTOR or ALE, both allegedly more advanced than Packet. My feeling on this is that if they cannot detect signals as well as Packet does, then which mode is more advanced, more suitible for use on the ham bands? That is really an unfair question in the case of PACTOR III and ALE, niether one of which was designed or ever intended for use within shared amateur radio spectrum, in the first place. It is not the square peg's fault that it will not fit in the round hole. In the end, if we are not operating an automated station, then a waterfall display in combination with speaker audio is the most effective and useful busy detection system we have at our disposal, and this will almost certainly continue to be the case for a very long time. For real-time automated busy detection, carrier detect is highly likely to be the best thing at our disposal - again for a very long time. The Reed-Soloman ID system is a great step ahead for digital operation. It is not really useful as a real-time busy-detect, but it does give us a first step on something that may eventually take us there. As standards and hardware evolve over the years, we may eventually embed information into our data streams that can be instantly recognized as 'busy' by our software. - It may even approach the speed of carrier detect, and work with all modes. But don't hold your breath, it's not right around the corner. 73 DE Charles Brabham, N5PVL Prefer to use radio for your amateur radio communications? - Stop by at HamRadioNet.Org ! http://www.hamradionet.org
RE: [digitalradio] Re: HF International Automatic Subbands
This is true that only the FCC has set up automatic sub-bands. Most other countries adhere to the RECOMMENDATIONS of the IARU with respect to where and how to operate but these do not carry the force of law. This, and years of good operating practices has defined band operations. In Canada, amateurs are limited to a maximum power output, and a maximum bandwidth (6khz) except on 30M where it is 1khz bandwidth. Even with the freedom to operate any mode anywhere, the vast majority of operators more or less follow the established band plans.
