DATV-Express Project - July update report
Posted: Sun Jul 31, 2016 1:58 pm
Ken W6HHC has recently published an DATVtalk14 article describing the capabilities and features of the new DATV-Express software for Windows called Express_DVB-S_Transmitter. DATVtalk14 is inside the recent CQ-DATV issue 38 free online monthly e-magazine. A free copy of CQ-DATV issue 38 can be obtained from http://www.cq-datv.mobi/ebooks.php in both PDF and ePub formats.

Ken W6HHC continued to update and clarify the Users Guide for Windows. Currently draft06 of the Users Guide for Windows is available for download from the http://www.DATV-Express.com project website on the DOWNLOADs page. Quite a long discussion about setting up vMix Basic (an optional video-mixing tool) occurred on the Yahoo forum for DigitalATV. The DATV-Express Users Guide does not cover set-up and running vMix in detail, since it a free third-party product and there are tons of YouTube tutorial videos describing how to set up and use the vMix product. At the end of this Yahoo forum discussion, Bob WB6KWT was able to successfully run vMix Basic with the DATV-Express v1.11 software. The only problem observed with vMix was that Ken could observe "occasional spectrum analyzer dropouts" within the DVB-S haystack when using his old Intel 3GHz Duo Core DELL notebook. Interestingly, WB6KWT was not having any dropouts using an Intel 2GHz Duo Core HP notebook. This tells me that vMix with Express_DVB-S_Transmitter may need to run on a reasonably fast computer....and Intel 3GHz Duo Core may be marginal CPU speed. Charles G4GUO suspects Ken's dropouts could be caused by the internal USB architecture/design inside his Dell notebook?
At this time, Charles G4GUO and Art WA8RMC are investigating the possibilities of a second more powerful board creation for DATV, so stay tuned. Nothing has started yet, so it may take a while to produce.
The project plans for the project team during August are to continue to support users of the beta v1.11 software for Windows. There are currently no bugs being reported.
