If an unattended station contains a busy frequency detector, then it can respond to an activation signal from a remote initiator as long as the busy frequency detector indicates that the frequency has not been in use. Additional confidence could be gained by designing an unattended station's control software to respond to a universal QRL signal, for example the letters QRL sent twice in 5 wpm CW. And won't that 5 WPM CW step on the hidden station anyway? Why 5 WPM if I can copy 20 WPM and more? 20 to 22 WPM is a usual speed for a satellite beacon, for one example. Well, probably with the new breed of morseless operators already showing up, any speed of Morse Code will be tagged as QRM. It is the proverbial snake biting its tail... It seems that the QRL signal is the only thing new out of this long inefficient discussion. (A zillion bytes in, three bytes out) And, taking it to the extreme, it could be tagged as QRM too...

Re: [digitalradio] NBEMS HF testing frequency suggestion
I too downloaded the .iso yesterday and immediately burned a CD to boot both of my computers. While I do not expect Linux to be able to properly drive my Samsung SyncMaster 225BW monitor to its native resolution, I can usually get by with one of the other resolutions. Even though not acceptable for normal use, it can work well enough for experimental use. The problem with both computers is that the program tends to lock up and crash or if it does key up I get a kind of machine gun sound in the audio coming from the sound card. This was also true of a previous version. Almost like an interruption in the stream. Now the curious thing is that in the past one one boot disk I was testing had another digital program which worked quite well. Could I possibly be correct that it was Digipan running under Wine? Even the audio settings were right on with that program, but on the same boot disk the main flDigi program would not run properly. Has anyone else had this problem? In order for PSKmail or NBEMS to even have any realistic chance at being used here in the U.S., it simply has to run under Windows at this time. Dual boots or Boot disk approaches are not adequate for practical use, although they can give you a feel for the program. Hopefully many of you are having better luck than I am. With a Windows version you could avoid the downsides of Linux. Although ten years from now it may be a different story, it was about ten years ago that I predicted that Linux OS would be a major desktop player in 5 years. You could say that I was a bit wrong on that call:( 73, Rick, KV9U Rud Merriam wrote: I just burned the CD. I will setup the laptop and rig to try on these frequencies and nearby.

[digitalradio] Re: NBEMS HF testing frequency suggestion
I had a number of problems with the system. It booted fine. I got both programs running. I have a Rigblaster Plug Play which is a USB serial port. I could not determine what serial port that would be to setup the C-IV for my Icom. I needed that for PTT. I also tried to follow the directions for setting up their rig control but (1) where is $HOME/.something? I opened the file viewer, clicked home but saw nothing that looked like that directory. I could see no input. This is a laptop and I only have mike input. I could generate output from the sound card so I think the sound card was found okay. I decided to pass on this for right now and switch back to Windows. This is the first use of the Rigblaster since I got arrived on Wednesday. It is working under Vista using DM780 and HRD. It is neat using the C-IV to control the rig! The only hassle is that the mike input is to hot so overdrives the sound card. Guess I need to put a pot to allow adjusting it. Since this is my first digital experience I do not know what signals I am hearing to select the digital mode. I did listen to a PSK-31 QSO. But while I can hear and see other signals I cannot get them to decode. Rud K5RUD

[digitalradio] Re: Need to Expand the HF Auto Band Segments
Posted by: Greg [EMAIL PROTECTED] Thu Oct 18, 2007 11:47 pm (PST) Apparently Bonnie is ignoring me because I keep asking how can you call winlink a 24/7 system when you need a live operator to generate the email and a live operator on the other end to read it. Lot of good that email does going to that automatic system only to sit there because no one, according to Bonnie's message below, is around to get it. Greg KC7GNM == Others are being ignored because the questions are too hard to answer. Back to the topic: I have read nothing that justifies why these wide band modes need to overtake the allocation of other modes. It appears to be a group that belongs to a sub-sub section of the population that believes they should have more of the pie over 99% of the whole. The emergency line of discussion is mute. All modes are needed during an emergency. But, there in no signal that is more important than the call for help in what ever form it need be. The op center reports and HQ updates should never interrupt or negate that priority. If you want the respect of other hams world wide, improve the robots. Make them more efficient in use of band width. Make them reactive to other signals on the frequencies. Make them better so they do not create QRM to other modes or themselves. Don't complain about your neighbors house when your own house needs fixing. As I often say to people who have problems, It is not the machine, tool, device, or technology that is good or bad, it is how you use it. Since my last three posts never got thru the email reflector, and I am not sure that this one will, I am done on this topic. I don't know if I have ticked off the moderators (no, Andy...) or the internet gods, but I am out of this discussion. I will delete this topic without reading from this point forward. 73 es God Bless, Dan, KA3CTQ __ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Alan, Your post just shows how people are missing the point. Just who is going to be able to copy D*? I wouldn't bet my life on D* communications. Would you? Too few people able to copy it. I might change my mind in 10 years but for now it's a fringe mode. One needs emergency communications modes that can be copied by just about anybody. 73 de Brian/K3KO --- In digitalradio@yahoogroups.com, Alan NV8A [EMAIL PROTECTED] wrote: On 10/18/07 12:01 pm Brian A wrote: The digital systems being proposed for emergency use require a rig with antenna, a computer with soundcard and functional software.

Re: [digitalradio] CQ DRCC...
Steve and group, A local ham in our area started the SKCC and there was quite a bit of interest in this. In fact, he mentioned to us that within a short time that if we wanted a number below 1000 we would have to hurry to get one. The point is that those who were interested in this signed up for a number. I think that this appeals more to contester types or paper collectors, of which there are quite a few out there with CW and voice since they make up the greatest number of operators. Probably the best example of the numbers game is the Ten-Ten International organization. You have to join for at least one year to get your number, after contacting 10 Ten-Ten members. Then it was good for life to that individual, even if you changed calls. This was done to promote 10 meters which at one time some were concerned could be lost due to low activity, as was 11 meters, when it was taken away from hams and given to the public for CB. They set up an awards program in addition to the basic number. With digital hams, you have quite a wide gamut of different interests and perhaps contesting and paper chasing is not as as large a percentage. And since we have very few hams who actually do digital modes, that means there is not that many who are interested in participating. The DRCC is not really an organization like other groups and the hams who have numbers did not join a group to receive them, so it is a very different situation. This reflector often discusses the modes and bands that we are using various digital modes, especially when a new mode is first developed and used. But it is not the primary interest of the participants which can only be determined by their interests and what they value. 73, Rick, KV9U n6vl wrote: Andy came up with a good idea a few weeks ago. He created the DRCC. It is a spin off of the Straight Key Century Club, of which I am a member. Unlike the SKCC, the DRCC hasn't taken off. The SKCC reflector on Yahoo has a lot of activity with ops excited about working CW the old fashioned way, with mechanically sent morse code. The SKCC is similar to FISTS, arguably the most popular CW organization. Why can't the digitalradio reflector have a similar degree of activity discussing modes, bands, and where to collect numbers. I think this is what Andy hoped for. After he, issued the numbers, I haven't sent a single message about how to go about collecting numbers. Does this mean digital ops don't have the same enthusiasm as CW ops? I don't think so. Let's give the DRCC a shot! 73, Steve N6VL
[digitalradio] Re: Newbie question...
Thanks for the clarifications! I suspected that using a DSB TX would result in two signals, but was unsure as the PSK31 modulation scheme itself results in a DSB signal. Summary: not a great idea to use a DSB TX for Digimodes.

[digitalradio] Re: Need to Expand the HF Auto Band Segments
I can tell you why. Because P3 is 2.4khz wide and every other mode you mentioned is much smaller so it takes up less spectrum and the fact that it is being used for email that is technically against part 97 because there is an alternative called sailmail out there.

The problem with creating another organisation that encourages digital modes is that there are already two that I know of, which are quite closely related, called the European PSK Club ( http://eu.srars.org/index.php ) and the Olivia Modes Club ( http://www.oliviamodesclub.net/ ). Although EPC uses 'European' in its title, there are members from several non-European countries who have become members, in the same way as the GQRP Club has a number of members who are not in the UK, but are able to be full members anyway. Then there is the Digital QSO Club ( http://dqso.net/start.html ) and probably others that I've not yet come across. Cheers - Dave (G0DJA) EPC number 1117 OMC number 069
