DATV-Express Project - October update report
Posted: Sun Nov 01, 2015 3:34 pm
The order to build and test a third production lot for more DATV-Express hardware boards was started by Art WA8RMC around 2015-10-07. The project team is pleased to announce that 25 blank PCB’s arrived on 2015-10-28 and were hand-carried over to the board assembly vendor on the same day. Assembled PCBA’s were picked up on 2015-10-30 and the first ten boards that Art tested worked perfectly. Art declared to the project team “let the flood gates for orders open…” and sure enough he received an order for ten boards on the same day. The large order came from the Mt Diablo ARC that has recently put up a DVB-S DATV repeater, W6CX, near San Francisco.
Charles G4GUO has written software and is experimenting with two new applications for the DATV-Express board that run only on Windows OS (no linux involved). The two apps for the hardware board are:
* DatvExpressServerApp is an alpha-release program to transmit DVB-S DATV running only on a windows PC with the hardware board. (no linux). In addition, the app can be used to run a webcam and no Hauppauge hardware is required!
* DatvExpressSdrApp is an alpha-release program running only on a windows PC to transmit FM or SSB using the hardware board.
PLEASE NOTE - these two applications are experimental and are likely to be full of bugs. They are provided as a service to the DATV-Express community.

Ken W6HHC has alpha-tested and then uploaded a zip file called DATV-Express-Utils_v1.2 with the two apps written by G4GUO to the DATV-Express Project web site at http://www.DATV-Express.com . Look for the zip file on the DOWNLOADS page. Currently there are only three README files in the bundle…so documentation is very light. There are a bit more details about the DatvExpressServerApp for DVB-S that can be found in my DATVtalk13 article in the free eMagazine CQ-DATV issue 27, go to http://cq-datv.mobi . But, because the apps are experimental and documentation is very light….you are essentially on your own...so please do not expect much in the way of support, yet.
Charles G4GUO gave a presentation at CAT15 in September on the DATV-Express.

See PowerPoint and PDF slides at http://www.W6ZE.org/DATV/ (click on the PRESENTATIONS link).
Ken W6HHC is working on a brief User Guide to install DatvExpressServerApp and DatvExpressSdrApp as time permits. Charles G4GUO is working on making some changes to DatvExpressServerApp to use multicast-UPD, a more professional approach to UDP for this application that was suggested by Jean Pierre F6DZP. Finally, the plans to finish the remaining task before finally releasing v2.04 for ODROID, Update User Guide for ODROID, is still on the “stack” of “things to do”…..it just got pushed down the stack a bit.
