The DATV-Express Projects

MiniTiouner-Express Receiver Assembly

September 28, 2021: MiniTiouner sales have slowed to the point where is is not worthwhile to produce more assemblies so MiniTiouners are no longer available. We are working on a new stand-alone DATV DVB-S/S2/S2X- DVB-T/T2 complete wired and tested receiver to replace the MiniTiouner. It will be a multichannel unit optimized for repeater operation at a very attractive price. We hoped it would be available by the end of 2021 but recent IC shortages have impacted that significantly. Example: an IC that we need 3 of, normally costs $2.00 each. It  is now in excess of $150 each because of very limited supply. YES, I SAID $150.00 EACH!  The T.I. production target is August 2022. We are re-designing to work around that.

We thank everyone for their support of our product in the past and hope you will stay with us in the future for there is more to come!

DATV-Express Transmitter Board

As of 9/27/2017 the DATV-Express Project depleted the inventory of DATV exciter boards but due to popular demand, in 2019 we decided to make another production run. The Analog Devices ADALM-PLUTO SDR Tx/Rx is available at a price of about US$160 and the mini-LimeSDR Tx/Rx from Lime-Micro is about US$170. However, the DATV-Express board produces a better and higher RF output signal and has a useful 1dB/step software controlled output attenuator to help match it to a power amplifier. We supply a complete installation and operation manual for the DATV-Express board. Also, support for the DATV-Express hardware will continue and the DATV-Express software will expand to support new hardware that becomes available. Thank you for your interest over these years.

DATV-Express Transmitter Software for Windows

The DATV-Express Transmitter software, currently v1.25LP14, has continued to expand to support new lower-cost SDR boards 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
