DATV-Express Project - February update report

Post by KenW6HHC » Fri Feb 24, 2017 11:44 pm

Art WA8RMC reports that the production build of DATV-Express exciter boards launched in January has been completed and DATV-Express boards are now back in inventory. WA8RMC finished inspecting assembled units and testing this next batch of hardware boards. After unexpectedly being flooded by orders around the end-of-the-year, the project team had to stop accepting orders for boards. The PayPal ordering button has now been reactivated on the project website.

You can order a board from the http://www.DATV-Express.com website using the PURCHASE A BOARD link (along the top). You must register on this web site to purchase a board. All boards will ship from USA. Art has shipped out the next four orders in late February.

Ken W6HHC had a chance to prepare a DATVtalk article that provides an overview of the capabilities of the MiniTiouner analyzer/receiver for DVB-S/DVB-S2 that is designed by Jean-Pierre F6DZP.

W6HHC had been using the MiniTiouner to finish testing of the DATV-Express for Windows software release (v1.23). In W6HHC’s opinion, the MiniTiouner is not only a valuable DVB-S and DVB-S2 analyzer…but MiniTiouner is the “best DVB-S/S2 receiver that Ken has ever used”! The MiniTiouner receiver is so easy to use….
1) Set the frequency you want
2) Set the SymbolRate you want
3) Set the protocol you want (DVB-S or DVB-S2)
No more blind scans, etc - are needed to see a new received signal.
The article, called “DATVtalk16 - The MiniTiouner Receiver/Analyzer for Digital-ATV”, can be downloaded from the CQ-DATV issue 45 eMagazine (free) at

Charles G4GUO has been relaxing by working on a few fun DATV projects. No LimeSDR efforts last month and no DATV-Express efforts for a few more months.

“Project speed set to time to relax a bit”…de Ken W6HHC

I suppose you could call it fun but I am actually working on Digital Pre Distortion DPD
based on memory polynomials using a LimeSDR and a NVIDIA GPU.
I am using this technique
