DATV-Express Project - October update report

Post by KenW6HHC » Sat Oct 29, 2016 10:58 pm

Charles G4GUO was able to correct the last reported problem for DVB-S2 protocol and has released v1.23 software for Windows. Also, an experimental set of coding for DVB-T protocol (2 MHz and 1 MHz channel-bandwidths only) was included in that Windows software release.

Charles points out that the current v1.23 software for DVB-T is running close to the limit of the USB-2 real-world thruput limits and the software requires a fast and well-designed PC for the DVB-T transmissions to be received without problems.

Ken W6HHC completed the Users Guide for Windows (draft 10) to now include DVB-S2 and DVB-T operations. This latest draft is based on the v1.23 software). The latest software for Windows and Users Guide for Windows PDF and a companion NOTES.TXT file can now be downloaded from the project web site at http://WWW.DATV-Express.com using the DOWNLOADS page.

During the month of October, the last DATV-Express board in inventory was shipped. Currently, the PayPal coding has been removed from the DATV-Express.com website and board sales have been stopped. The project team is looking for a “show of hands” via e-mail to see if there are enough hams willing to agree to a standby order…if more boards were to be built. No payments are required for a “show of hands” e-mail, just your commitment to buy a board or two if the project team builds another production-lot. The pricing will remain the same…US$300 + shipping (from USA) via PayPal.

If you are willing to agree to a standby order, then send an e-mail to
Support@DATV-Express.com
We currently have a list of seven standby orders (update - now 13 orders), and need a total of 16-to-20 orders or more to proceed with another board production-run.
