[digitalradio] DRM on Vista using a SDR-IQ as the receiver
DRM on Vista using a SDR-IQ as the receiver. http://www.rfspace.com/SDR-IQ.html To tie in the audio lines, I used VAC, virtual audio cable from: http://www.ntonyx.com/vac.htm Have DRM in digital mode and tune using about 12 KHz bandwidth in USB mode. Worked great here. If you get a conflict on Line 1 of VAC, set up two lines (cables) and use Line 2. Evaluation version work great. The promo voice is only heard on the AM mode of DRM, not on the digital. 73 from Bill - WD8ARZ http://hflink.net/qso/

[digitalradio] Software Link for WinDRM?
N1SU download link appears to be obsolete. Can someone point me towards source? I'd like to give this mode a try. Thanks, Kim WA4VKW

[digitalradio] 30m test of NEW QRSS mode in Multipsk
I will be experimenting with the new S L O W CW QRSS mode today from 1500 to 1530 on 10.139 (1000 Hz AF) using the 3 second option. I will also try the same at 22:00 UTC and 0100 UTC. . -- Andy K3UK www.obriensweb.com (QSL via N2RJ)
[digitalradio] "RANKING THE DIGITAL MODES FOR THE STEALH QTH with Tables.doc" paper from Ed Sack (W3NRG)
Hello all, Ed Sack (W3NRG) issued a paper which name is "RANKING THE DIGITAL MODES FOR THE STEALH QTH with Tables.doc" at the "ARRL and TAPR Digital Communications Conference 2007". Speaking of it, Ed aggreed to add his paper to my papers collection (PAPERS.ZIP file). Thanks to him. So the Ed's paper is available from my site. It is included in the PAPER. ZIP file. To download this ZIP file, paste this adress in your Internet Explorer or equivalent: http://f6cte.free.fr/PAPERS.ZIP Download the ZIP file and extract RANKING THE DIGITAL MODES FOR THE STEALH QTH with Tables.doc. The beginning of the paper is the following: RANKING DIGITAL MODES FOR A "STEALTH" QTH by Ed Sack, W3NRG Using the digital mode software "MultiPSK"1 as our guide, we find that there are something like 40 different digital transmission modes available to the amateur radio operator. These modes range from the "historic" (Hellschreiber) to the "classical" (RTTY) to the "relatively recent" (example, OLIVIA.) The availability of software to transmit and receive these modes using the computer sound card has rapidly expanded their use in ham communications. Some modes are more popular in one part of the world than another. Some are preferred by DXers and some are the every day vehicles for QRP stations. All have had their advocates at one time or another and many have undergone several revisions, as is common with most software development.2 Most of the articles that discuss the performance of the various modes focus on their utility in DX (or EME3) work. We have not found much information which focuses on the ability of the mode to provide useful communications under the very marginal conditions that may occur in a "stealth" QTH where antennas are very limited and local noise conditions may be very severe. The author attempts to enjoy his amateur radio operations under what might be described as "condo-stealth" conditions. Due to the steel stud construction of the building in which he operates internal antennas are essentially useless. The only external antennas that do not attract COA attention are short whips which may be attached to the condo balcony. To make the situation more challenging, the condo building itself sits in the midst of other steel frame structures of similar height. Hence, the "straight shots" for the antennas are in two open paths between the individual buildings. If not all of that was a sufficient challenge, there are some very significant sources of external interference within the line of sight from the QTH 73 Patrick (F6CTE)
