-Thanks, that is helpful. I will give it a try this weekend. Andy K3UK -- In digitalradio@yahoogroups.com, Vojtech Bubnik [EMAIL PROTECTED] wrote: If I wanted to compare WSPR, JT65A, and Olivia on a 30M frequency at a given power output will it do that ? You need to run the WSPR/JT65A or Olivia software on your PC in parallel with pathsim. Digi software will produce sound to the sound card, pathsim will sample from the sound card and produce wav file. All you need is some kind of loopback between sound output and input. On my old laptop it was possible to setup the loopback on a single sound card by windows mixer. You just have to select recording from sound output. On my new laptop this is not possible and I have to connect earphone output to microphone input with a cable. There is also a freeware dummy windows sound driver on internet, which creates two interconnected virtual sound cards. The output of one is routed into an input of the other. After you capture the processed wav file by pathsim, you just need to play it back by any sound player and let the digi software run in parallel with the same sound loopback in action. The digi software will now listen to the distorted digital stream and try to decode. Pathsim will add configurable amount of noise to the signal. SNR is calculated relatively to the signal RMS. One needs to consider crest factor if he compares digital modes. But the modes you are interested in have all crest factor 1 (not true for Olivia, but I believe its crest factor is nearly 1 also). All three are single tone FSK mode. From the pathsim manual: If the AWGN source is enabled then Gaussian white noise can be added to the input signal in order to simulate various SNR ratios. An SNR of 0 means that the input signal rms level is equal to the noise rms level as measured through the 3KHz bandpass filter. 73, Vojtech OK1IAK

Re: [digitalradio] another non- contest on a no contest band
Hi Guys, What is the actual objection? is it you worry there will be some rule change in the future to allow WARC band contesting? You know there are other groups who promote the use of 30m for events too (and have done so for some time) including the FISTS club WARC Band Challenge - they even use a scoring system for it. What about RTTY or CW DX on 30m? there are many times that DX appears and the whole band is concentrated on working them regardless of the other users. This may not be a contest but it sure sounds like one. I don't think a digimode QRP Weekend is going to cause any problems to anybody as long as we avoid the QRSS segment which is the normal rule anyway. Realistically we will only be using frequencies from say 10.137 to 10.142, 5KHz (less the QRSS segment) in total. This is surely not a problem for anyone. As long as there is no required exchange, scoring system, goal of working as many people as possible I really don't see how you can call it a contest. If anything it will be a very interesting scientific study of which digimodes work at these levels and which don't. How can that be a bad thing? 73, Sholto KE7HPV.

Re: [digitalradio] another non- contest on a no contest band
Steinar, I certainly don't want a rule change to allow WARC contesting it would be a big mistake and if I honestly thought that the 30M QRP weekend could lead to that I would not participate. But events like our proposed QRP weekend will never lead to a rule change or even an acceptance of WARC contesting. The pressure to change (if it ever happens) will be from the big contest organizers like CQ ARRL and the majority of contesting amateurs. I am not particularly interested in contests (other than CW QRPp because it is a *real* challenge) but for many people it is a part of radio they enjoy and this hobby of ours is all about live and let live. BTW have you experimented with the Jason IFK mode on HF Steinar?

Re: [digitalradio] another non- contest on a no contest band
I am not a real strong supporter of contests, but it seems to appeal to the highly competitive type of people. But then I am not into DXing either which is closely related. But is there any kind of legal restraint on using the WARC bands for contesting? While most groups have indicated that they won't support such activities, would that really stop others? When I was first licensed in 1963 and joined ARRL to get QST, I did not really comprehend what was going on with contesting. It was not until I was relicensed in 1980 that I started to pay more attention to the various subsets of amateur radio. I was quite stunned to find out that grown adults will literally spend their entire weekend at a fixed operating position. My reaction was, this can't be true, people would never do such a thing. But I was wrong and they do. I have operated for an hour or two in a few contests as it can help some of your operating skills. And I have a rare prefix, so even DX stations tend to have an interest during the WPX contest:). Field Day finds me helping to set up and even operating an hour or two, but my interest is more in being able to provide emergency communication. (Yes, it is officially an operating event, but depending upon who participates, it is a contest to them). Now, the comment about QRSS is a good case in point of having some sub specialty interest that most of us don't even know anything about and will likely never even operate. I often will operate digital modes just above the PSK31 watering holes on 80, 40, and 20. And of course keep within the band and emission types permitted by my license. Other than that, how could anyone expect someone using a shared band to know any other special mode location? I have absolutely no idea about any special frequencies for QRSS or any other modes on 30 meters. If you asked me for where ALE soundings were made, I would have no idea, same thing for narrow automated stations who can operate wherever they wish to operate in the text data portions. The one exception is that I do expect all radio amateurs to realize that we have certain spot frequencies for NBEMS and ALE400 that they should always leave clear for the users of those modes;-) The main area that I operate digital modes on 30 meters is typically around 10.135 to 10.145. I know that there are packet stations toward the top of the band and also automated stations in the 10.140 to 10.150 area and I make very sure that I keep well away from the middle of the band due to the non radio amateur digital station and sometimes number stations that have precedence over our activities. Finally, I would have to say that here in the northern midwest part of the U.S., as long as 30 meters is open, there always seems to be stations operating. Generally, a few CW stations, sometimes a dozen or so, and up around 10.140 (like right now at about 1:30 in the afternoon) there is at least one PSK31 station, several Pactor, and some packet up high. 73, Rick, KV9U Sholto Fisher wrote: Hi Guys, What is the actual objection? is it you worry there will be some rule change in the future to allow WARC band contesting?

[digitalradio] JASON no tones
Jason on my XP HE PC does not generate audio tone when I press the TX button. The rig goes to PTT as expected but no audio. I do have the correct soundcard selected (as far as I can tell). Anyone else experience this ? Andy K3UK

If everyone who thought 30m was dead just called CQ, that opinion might change very quickly! Try it! It is a time-honored technique! ;-) 73, Skip KH6TY I agree Skip. A couple of years ago I tried to stimulate interest in an International CQ Day, any mode , CW, Phone, whatever. To honour Skip's point, I will get on 30M this weekend and actually call CQ. Andy K3UK

[digitalradio] Re: another non- contest on a no contest band
/snip/ It was not until I was relicensed in 1980 that I started to pay more attention to the various subsets of amateur radio. I was quite stunned to find out that grown adults will literally spend their entire weekend at a fixed operating position. My reaction was, this can't be true, people would never do such a thing. But I was wrong and they do. /snip/ As a fanatical DXer and occasional contester, you are 100% correct, Rick. It is true. My wife thinks I have something wrong with me. Maybe so, but it's harmless I tell her. Maybe I am too competitive? Think of the hacker golfer who spends tons of time on the golf course every free moment. He sacrifices sleep, social time, and relaxation time (the golfing is competitive rather than relaxing) for his quest of a par score. Only for me I sacrifice sleep, outdoor time, other hobbies, even eating just to catch some DX. It's an addictive personality thing, I believe. I have never smoked (only cigars, maybe three times in college) but after I worked the YK9G/Syria DXPedition for my 250th country today on 20 meter CW after 30 minutes through the pileups with my 100 watts, I felt like I needed a cigarette and a beer. Same feeling during contests - adrenalin flowing, competitive streak emerging, body tensing. Having said (confessed?) all that, I am concerned that any contest on 30M or other WARC bands sets a precedent which might not be a good thing. But it is balanced by increased activity on the band and interest in a growing field in our hobby (low power digital), which is always a good thing. Conclusion: result is neutral.

[digitalradio] SL-USB interfaced with IC-746 PRO and COMPAQ PC
SUBJECT: Having problems on 75m LSB PHONE with this new Interface set up. Hello Members: Can you make some sense out of this? Audio on 75m LSB Phone Mode is A + when: 1. SignaLink USB Interface is powered down and PC is powered down. -- OR -- 2. SignaLink USB Interface is powered on and PC is powered on. Audio on 75m LSB Phone Mode is TERRIBLE when: SignaLink USB Interface is powered down and PC is powered on. Might you have any suggestions why this is possible?? My THEORY is : since, the RADIO , SIGNALINK , and PC are all interfaced and linked, they are all dependent on each other. If the PC is ON and the SIGNALINK is DOWN , the audio on 75m phone is terrible. Turning the SIGNALINK back ON generates perfect audio on 75m phone. Please remember, this is a new experience for me..

Re: [digitalradio] Re: another non- contest on a no contest band
Don As one of the moderators of this list let you thank you for you post stating what I really can't. BTW - I did sent him a note saying that we really don't need the screw you comment. John, W0JAB At 09:04 PM 4/11/2008, you wrote: David WD4KPD, I guess the bring it on means you want a response. I noticed reading many of your replies that you leave these types of remarks below your name/call when you reply to message posts to get a point across for what ever reason so I can only assume by what you have listed before on other posts you want me to respond or as you say bring it on. I for one want to let you know that I did NOT provoke a response like you have given me but my post was in good and positive spirit of Ham Radio. I also did NOT post the 30 Meter Digital QRP Weekend to be belittled by you or anyone else you have voiced your opinion and I can't change that nor will I try but by you voicing it publicly you are trying to sway others in your views they will have to decide what is right and wrong or what they agree or disagree with according to facts so far the facts are not on the Internet but by listening to the great bunch of digital ops on the 30 Meter band that have no intentions of contesting on the 30 Meter band. If you don't mind David I will answer your post publicly since you were so fast at responding to my message post that again didn't warrant such a reply you have given it but then again you have your own opinions so that is a right no one can take away and many have died for you to have that right here in the good old USA. for all intents and purposes, this non-contest is still a contest ..Right from the start your reply message changes my message post from a 30 Meter Digital QRP Weekend to ANOTHER NON-CONTEST ON A NO CONTEST BAND is of a mean spirited nature and negative and I'm not sure why that is but that is your call (many times I just use my delete key if not intersted)for those of you that do decide to work the 30 Meter Digital QRP Weekend on April 19/20 you are going to be very disappointed if you are looking for a contest. All you are going to find is a bunch of really nice digital ops making casual contacts, experimenting with low power, long ragchews and DX if the band allowsyou will NOT find is any rules on about a contest because there is no contest no rules for exchange no time limits ..no points .no logs are requested to be sent in for any contest prize for the weekend because there are none .the only winners are those that participate and have fun. there is a sponsor .a sponsor is one that spends money maybe on a contest or something and I guess would give out prizes for those winners and might gain something from all this. Again we might be putting the word out to give 30 Meters a try and we do hope for more Hams to participate on the 30 Meter band so that is true (could care less if they join the 30MDG because our main focus or goal is to have an increase awareness and usage of digital modes on 30 Meters if they join in 30MDG so be it but not our goal) ..having fun on Ham Radio is FREE and we don't spend any money on FREE fun again there is no winner for the most contacts or having the most points on the QRP Weekend because again David there are no points, contest like exchanges or contact limits and good luck on having fast contacts because there is a nice bunch of long winded ragchew digital operators on the 30 Meter band so you will have a hard time getting to that next contact very quickly even if you wanted to. and bragging rights are earned by contesters in the organization .oh really? I think bragging about how far a QRP signal may go or who hears your low power signal and maybe how many contacts you make using low power and to what areas of the World those contacts are made is what we do all the time, right? You David post your MEPT reports and I don't think that is contesting on 30 Meters yet it is bragging of sorts and very informative (thanks for doing that by the way). BTW, we are NOT an organization but a group of average `Joe digital operators just having fun on the 30 Meter band. I agree though there are some contesters in our group and some darn good ones, I understand you don't like contesting and that is fine and you have that right to not like it as I'm not much on contesting myself but even though there are contesters in our group doesn't mean they are contesting on the 30 Meter band in fact just the opposite as I think from reading the mail on many of them since 30 Meters is a WARC band and a NO CONTEST band they seems to like this place to come to and ragchew and get to know other Hams vs when on the other bands getting hammered by folks just needing a fast contact and 599 report to get them in the log and sometimes QRM'd to the degree they couldn't carry on a good ragchew if they wanted to. it may be legal .yes it is legal to use the 30 Meter Band (we are secondary users should give way to gov/com'l

Re: [digitalradio] SL-USB interfaced with IC-746 PRO and COMPAQ PC
Lee, I am probably not going to be much help on this, but I have had a similar problem with RFI and my rig is very similar (ICOM 756 Pro 2) and has the same rear connection. With one antenna, I would get enough RF in the shack to cause phone distortion. When I got an amplifier, it was much worse and prompted me to abandon my sort of homebrew interface using Radio Shack isolation transformers embedded in one of their products. When you say the Signalink is powered down, how does this happen? I went to the Tigertronics web site and it says that the power is always powered by the computer's USB jack. Is there also a power switch that powers down the unit or is it powered up whenever plugged into the computer? Are you unplugging it from the computer and leave the USB cable hanging loose? If you did that, then is it possible that there is some RFI getting into the cable? If you have a dummy load, you could see if the problem still exists when transmitting into it. Otherwise, do you notice increasing distortion with increasing RF output power? Do different antennas vary the problem? Different bands vary the problem? 73, Rick, KV9U KB1NAL wrote: _SUBJECT_: Having problems on 75m LSB PHONE with this new Interface set up. *Hello Members:* ** * *Can you make some sense out of this? _*Audio on 75m LSB Phone Mode is A + when:*_ *1.

Re: [digitalradio] Re: another non- contest on a no contest band
2008/4/12, Don [EMAIL PROTECTED]: What would you suggest David to promote the 30 Meter band? I'm all ears and you can list all your ideas here or email me direct if you wish. Simple. The 30m band don't need any promotion :) I like and use 30m because : - There is no contest - There is no SSB - There is no CW pile-up with tons of OMG CQ D FFS 59 KTHXBYE running on overstressed KiloWatt-class amp (who said CW had no bandwidth ? :p ) - lot of QRPer, fuzzy mode, Visual MEPT, ... - in 1 word : peacefull band :) The 30m band have many unofficial (a real gentlman agreement) sub-sub-sub-band. And bringing people that are not used to the lovely 30m band is a bad idea. I love the idea to promote QRP, QRPp, unusual digital mode. And the 30m band is perfect for that. 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. Event, Contest, ... shouldn't happen. It is, of course, totally ignored by most operator. 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. And about the bring it on. It look like a random signature from his mail client. *hugs* -- F4FQM Kerunix Flan Laurent Laborde
