MiniTiouner-Express Receiver Assembly

The MiniTiouner-Express receiver/tuner/analyzer assembly is a completely assembled and tested unit contained in a small aluminum enclosure about the size of a 2 stack deck of cards. The DATV-Express group created the design, construction and sale of this item named “Minitiouner-Express”. It is available through PayPal for $75 plus shipping. The hardware assembly is used with the free software (called MiniTioune) by Jean Pierre Courjaud F6DZP.

The unit connects between an antenna(s) and a PC computer USB2 or USB3 port using the Windows 7, 8 or 10 operating system. It receives DVB-S/S2 144MHz to 2420MHz digital television signals for symbol rates between 75K and >20M symbols/sec when used with the MiniTioune software.

In operation, the computer monitor displays the received video and graphic landing dot constellation to show the incoming signal level, quality, FEC, MER and setup information.

DATV-Express Transmitter Board

As of 9/27/2017 the DATV-Express Project depleted all inventory of DATV exciter boards. On 11/28/2017 the project team declared an END OF SALES policy.  The main reason to NOT build more boards is that new DATV products will become available soon (March 2018?) that are SDR-based, both Tx and Rx, and are lower-cost than DATV-Express. The Analog Devices ADALM-PLUTO SDR Tx/Rx may be available at a price of US$100 or US$150. The mini-LimeSDR Tx/Rx from Lime-Micro is rumored to ship in mid-March at a price of US$140. Both of these new SDR boards will be lower priced than the DATV-Express Tx-only board (US$300). Support for the DATV-Express hardware product will continue and the DATV-Express software will most likely expand to support new hardware that becomes available. Thank you for your interest over these years. 


DATV-Express Transmitter Software for Windows

Although the DATV-Express hardware board is no longer being sold, the DATV-Express Transmitter software, currently v1.25LP14, has continued to expand to support new lower-cost SDR boards that have recently come to market (thanks to the effort of Charles G4GUO). The current hardware SDR boards that are supported are:

  1. the DATV-Express hardware Tx board
  2. the LimeSDR-USB Tx/Rx board from Lime Micro
  3. the LimeSDR-mini Tx/Rx board from Lime Micro
  4. the PLUTO-ADALM Tx/Rx board from Analog Devices
