[digitalradio] Automated Launching of Dxkeeper and Commander when Multipsk starts?
All, Is there a way to automatically launch both Dxkeeper and Commander when Multipsk is starts? They work well together and it would be nice if they launched together. Just a thought. Tony -K2MO
[digitalradio] Re: Comparison of RTTY software sensitivity
By synchronous detection, Vojtech, do you mean treating the first start bit as the beginning of a synchronous multi-character sequence, thereby providing some protection against broken start and stop bits within that sequence? Brian K6STI referred to his decoding technique as employing a flywheel, which I interpreted as a means of adjusting the synchronous timing with high-quality start bits decoded within the sequence. Dave, what I mean is to consider all edge into sync recovery. Most software I know is using pretty stable clock and fills the spaces with idle characters. The decoder needs to know how long the stop bit is, which may be estimated on the air or configured by the user. I suppose 1.5 bit length is the most common? Then you may try to search for raising/falling edge at 2x bit speed and slowly adjust the sampling point. Yes, it is some kind of flywheel, that any synchronous decoder like PSK31 uses. 73, Vojtech OK1IAK

If you have DXKeeper installed then you probably have installed DXLab Launcher as well. If not then download the Launcher from one of DXLab's download sites, http://www.dxlabsuite.com/download.htm , and follow the instructions. - Once you have the Launcher installed run it and open its Config-Window. -Select the application files for Commander, DXKeeper etc. in the DXLab Applications pane. -Check the Enable-boxes for Commander and DXKeeper. - Select multipsk.exe in one line of the Other Applications pane and check the Enable box. - If you like to start all three applications whenever you start the Launcher check Auto Start in the Config-Window as well. Whenever you like to use all three programs start the Launcher and click on start in the Launcher window or - if you have chosen the Auto Start option- all programs will launch automatically. You should be aware, however, that the Launcher will terminate the DXLab applications when you click on terminate in the Launcher window but not Multipsk. Multipsk needs to be shut down manually. This configuration works very well at my second qth where I use more or less only weak signal modes like Olivia. 73 Juergen, DL8LE --- In digitalradio@yahoogroups.com, Tony d...@... wrote: All, Is there a way to automatically launch both Dxkeeper and Commander when Multipsk is starts?

Re: [digitalradio] off topic, 3819Khz
Hi Andy I probably was too far out with this off topic , but after a half an hour listening to the stream I was in chock. I have never heard such bad language on the band and since people on this group often write about US regulation I took the chance to ask. Yes, the Pinell radio is a great toy. It has over 15,000 Internet radio stations and Podcasts to choose from. 73 de la5vna Steinar On 23.01.2010 16:41, Andy obrien wrote: Regardless of who is in Govt at the current time, there seems to be an increase in the USA of hams who express political opinion over the air.

I am not going into the politics here, but is this type of network allowed in US on the HAM band ??? There is a widely held misconception about what is, and is not, allowed to be discussed on air. There is always the good sense point of view that certain topics will be likely to stir up bad feeling and argument and are, therefore, best avoided in the interests of good manners and avoiding embarrassment. However, legally it is usually the case that politics, religion and sex, for example, are not actually banned as subjects for discussion. That said, from the reports of the group in question, you have to say that a) they are talking to other people who hold their views and are unlikely to welcome any constructively opposing views and b) once you know their callsigns you can avoid having anything to do with them, so it's going to be a self inclusive group that is going to show its prejudice to anyone that listens for a while. A long time ago I stopped arguing with people with whom I was unlikely to persuade of my argument, or who I wasn't likely to ever be convinced of their point of view, as just being a waste of time on both sides. I suspect that groups such as those mentioned fall into this general category and I would also include groups who hold similarly extreme points of view on the other side of the political argument as well... A good case in point was a colleague of mine, who was espousing his own political point of view about how he thought people should vote in the UK the other day. In conversation over a pint or two I gave him my point of view, which he didn't accept, but I guess we agreed to differ and left it at that. Maybe that sort of conversation might be 'OK' on air, but I wouldn't want to have it because personally I don't think the Amateur Bands are the place to have conversations that you have in the Pub. But that's just my point of view. HI. Dave (G0DJA)
[digitalradio] Future of ALE and HF Link.
I have decided that I will not be a part of HF Link, in the formal sense. Many members of the Yahoo group HFlink have been helpful over the years and Steve especially has been of tremendous help to all. However, I have concluded that the rigid control and moderation of that group, have contributed to the failure of ALE to take hold as an effective method of amateur radio communication. Despite years of efforts, ALE remains perhaps the least used method of ham radio contact management, and is regularly used by less than 75 hams world-wide. I know of no other amateur radio method that is dependent solely on one group , and that one group has such prohibitive practices that it essentially dictates terms. The copyright policy of the HF Link group is directly contributing to a lack of openness that is rarely seen in the amateur radio world. PSK and digital modes have many organizations and email lists, CW has lots of groups, SSB-phone a zillion clubs, RACES/ARES accepts a wider choices of systems, weak signals modes like JT65A have varying groups, but ALE on hams bands remains centralized via HF link. Winmor has tight control on the software but is generally open to input and openly allows dissent. ALE should be allowed to flourish in an open market where hams take the idea and help it evolve and succeed. Steve and Charles Brain have made huge contributions but the warehousing of it via HF link have reduced it to a little understood concept . I will continue to use ALE both PC-ALE and Multipsk . but no longer associate with HF Link. I have raised this matter before , and have received constructive comments the suggest that the control is to prevent ALE bashing . I think that there is not a lot to bash about ALE...it is a very effective system, However the protectionism exhibited by HF Link has harmed ALE more than the occasional ALE bashing would ever do. So, the problems of busy detect and unattended operation notwithstanding, I will remain an advocate of ALE and hope others will help it get rid of its shackles. Heck , lets get rid of ALE as an emcomm concept , it isn't really (it could be , one day). ALE might be more sellable as a DXing method or net control software! Andy K3UK
RE: [digitalradio] Future of ALE and HF Link.
Re the control is to prevent ALE bashing Across a broad range of technical offerings, organizations that actively solicit criticism and respond constructively tend to flourish, whereas organizations focused on protecting their baby often fail to gain traction, despite expending a comparable amount of energy. The open approach motivates users to help - in reporting defects, suggesting enhancements, and spreading the word - and naturally leads to a enthusiastic user community. The defensive approach drives off everyone but the true believers; only something incredibly valuable can survive this. 73, Dave, AA6YQ From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com] On Behalf Of Andy obrien Sent: Sunday, January 24, 2010 8:24 PM To: digitalradio; alera...@yahoogroups.com Subject: [digitalradio] Future of ALE and HF Link.

[digitalradio] Super narrow filter: PSK31 with HB9DRV SDR-RADIO
Finally! When I bought my TS-2000 a couple of years ago, I was aware of one criticism for the digital operator super narrow filtering in SSB was not as easy to achieve as in other rigs.It can be done via a radio equivalent of standing on your head , using CW to receive and USB to transmit. The steps to achieve that are not easy to automate, so I have found it difficult to cope with those monster nearby PSK signals that swamp the waterfall, and could be eased out if I had better filtering in USB. So, tonight, I decided to see how that would be addressed with my new SDR-IQ receiver and Simon Brown's preview release of SDR-Radio . I was very happy to be easily able to dial in narrow filters, til my heart's content. All at the stroke of a mouse slider, couldn't be simpler. Simon's software is still very early in development , so not yet seamlessly integrated with his DM780. Take a look at this screen shot if you are interested, http://www.obriensweb.com/36hz.jpg I highlighted items of interest in a red ellipse. I used Mixw to decode the PSK31 because SDR-Radio does not do it itself. Yes, I know... Mixw displays 20M, but I was actually on 80M. I have yet to try this when there is a monster signal nearby that needs to be nulled out , but I think the results will be good. Andy K3UK

Have a go with Winrad or WinradHD as well Andy, you'll find that both those programs allow you to widen and narrow the bandwidth and adjust the filters. The use of click and hold whilst sliding the filter skirts is very useful. Using VAC you can send the audio to DM780 or any other digital mode program that recognises the VAC drivers. Dave (G0DJA)
