[digitalradio] 10/12 meter openings
All, The 10 and 12 meter bands are open to the northeast as of 2100z. Good signals from South America and the Caribbean. Tony -K2MO
[digitalradio] Re : 10/12 metre openings
Both bands were open in Europe, but didn't produce anything of interest. The same people who operate on 40, 30 and 20 metres just turned their attention to 12 metres, there was no, what we could call, DX. Mel G0GQK
Re: [digitalradio] Re: Amazing ! Multispsk with SDR 48 Khz RS ID
Hello Ed, Very interesting, Andy. I had not noticed the RX RS ID button on the SDR window or the RS ID configuration window. Yes you have it: a RX RS ID and a RX Call ID buttons to the right of the SdR window. In case of reception of a RS ID by the SdR, it is also proposed to jump to the transmission shifting the bandwidth containing the RS ID to the base band. The MultiDEM program looks very nice. It has more functionality than the built-in SDR front-end but it doesn't appear to have the RS ID decoding option. Is that a possible addition in the future? Is there an advantage to the built-in SDR function such as latency, etc.? The Multidem has more SdR RX/TX functionnalities that the Multipsk SdR, but of course I use more or less the same code. There is not RS ID decoding in Multidem as it is not the objective of this soft. 0.0% to 0.1% is really very low. As there is an AGC, the level in the standard waterfall must be much higher. The problem with very low level depends on the sound card. If down to 10 bits it is only noise (standard sound card), all the signals (in base band) good or not will be mixed with the sound card noise and they will be bad. Now if the first 16 bits are clean of noise (Multipsk SdR working on 16 bits), the signals (in base band) will be good. The best is to have a comfortable global level, so there will be no doubt. 73 Patrick - Original Message - From: ed_hekman ehek...@cox.net To: digitalradio@yahoogroups.com Sent: Monday, February 15, 2010 6:14 AM Subject: [digitalradio] Re: Amazing ! Multispsk with SDR 48 Khz RS ID Very interesting, Andy. I had not noticed the RX RS ID button on the SDR window or the RS ID configuration window. Patrick, Is there a way to keep the RS ID window open while using the RX/TX screen? Is there any other notification of the RS ID detection when using the RX/TX window? The MultiDEM program looks very nice. It has more functionality than the built-in SDR front-end but it doesn't appear to have the RS ID decoding option. Is that a possible addition in the future? Is there an advantage to the built-in SDR function such as latency, etc.? I am still puzzled about the Global Level reported in the SDR screen. Mine still shows 0.0% to 0.1% although the decoding seems to work fine and the receiver noise is visible on the waterfall. The input levels on both computers are set to maximum. I tried boosting the input with microphone preamps but it had no effect. The sound card on one computer is a Soundblaster Live! 24 bit External and the other computer has an M-Audio Delta 66. I noticed Andy's screen shows 10.8%. It doesn't apear to be a problem but I am wondering what I am missing in the settings.

Patrick should get a Nobel prize for this, it will make digital mode hunting even better . It works as advertised. Phil KA1GMN and I did a test. I placed my received on 18090 and Phil sent an RS ID (he was CQing) on 18100 As you will see in http://www.obriensweb.com/phil.jpg , the wider (48 khz wide) Multipsk detected his RS ID , sent an audible beep to my PC , and alerted me visually that an RS ID was detected up 10 kHz. This could be very useful for bands like 20M where there is quite a wide range of frequencies for the digital modes (14065 to 14109). I finally did this by stealing my son's PC , just to test. My Pentium 2.3 single core CPU would not handle the load, but my son's Pentium single core 2.7 CPU did so, easily. See http://www.obriensweb.com/multipsksystem.jpg for system info. Thank you Patrick. At the moment, Multipsk is the only application that lets you feed wide I/Q data to it so that you can decode signals wider than the normal audio bandwidth, Andy K3UK Try Hamspots, PSKreporter, and K3UK Sked Page http://www.obriensweb.com/skedpskr4.html Yahoo!

[digitalradio] Netbook or Laptop better?
I run MultiPSK Ver 3.13 on a VERY old IBM ThinkPad running Win98 at 166 MHz. I'd like to get a newer, faster, better laptop. Is there any disadvantage to using a netbook as compared to an actual laptop notebook? 73 Thanks, Jerry KDØCA Washington, IA
[digitalradio] Logging
Hi all. Since the launch of the latest version of DX-BUDDY on www.dx-buddy.net the stream on Wolfgangs website was +300% so we can say that a lot of people where interested in this program. And because Wolfgang and I are looking further than just DX-BUDDY we came up with the idea to make a (freeware) logging program just for shortwave listeners. I know that on the www we can find many logging programs but mostly it is for ham-amateurs only. And for the SWL-logging program we need your help. We want to know from you, shortwave listeners, what features must be in the program except from logging frequency, call sign, station, date, time, loggers name, and remarks and most of all we want to know if shortwave listeners need such a program. For your ideas, suggestions and other stuff send me a e-mail: pdeh...@vodafonevast.nl or postmas...@shortwavemonitor.com Regards, Pieter Wolfgang www.shortwavemonitor.com image001.gif

Re: [digitalradio] Re : 10/12 metre openings
This raises an issue that I have faced, that the digital modes are still so much of a minority mode, that many days we just run in to the same hams over and over again. It is nice to meet old friends but some fresh meat is nice, every now and again.

If you only want to run digital modes on ham radio (espically portable) and no or very few other applications, the netbook is fine if you do not mind a small display and smaller keyboard. It does not take too much of a cpu to run many of the ham applications. I have a netbook Asus 1000. It works fine for what I uses it for, but I do have a regular desktop computer to use for serious applications. If it was the only computer I had, I would go with a regular laptop. I do like the long battery life of this modle. Something around 6 to 9 hours depending on usage. While I could add an external dvd or other devices, I have not done that. I have gotten a TV/FM radio thing that cost about $ 60 to make it a TV receiver.
Re: [digitalradio] K3UK moves ahead of DP1POL in rankings
Congratulations, Andy. I caught this post out of the corner of my eye, and noticed my callsign DEAD LAST. I don't even remember uploading any logs to this site. I'm not really a contester, and only participated in one on New Year's Eve a couple of years ago. I guess I might as well upload my entire log just for the heck of it. -- Dave - AF6AS -- From: Andy obrien k3uka...@gmail.com Sent: Monday, February 15, 2010 2:13 PM To: digitalradio digitalradio@yahoogroups.com Subject: [digitalradio] K3UK moves ahead of DP1POL in rankings I am ahead of DP1POL now, where are you in the Digitalradio club rankings?
