VersaTune-Express Receiver assembly
Software work continues. Major breakthrough recently. There were two major bugs we discovered and fixed that now allows the unit to function. There are many minor bugs to be fixed, some known and I’m sure some unknown ones as well but those are easier. I have a working model on the internet that allows me to see and edit the entire setup screen remotely. When we get more items fixed, we’ll publish the web address so users can view it in real time. More information shortly.

VersaTune-Express Receiver assembly
Software work continues. Hardware is ready but software bugs still need work. Thought now is to create a non-scanning version until we resolve the bug issue. Also, the available time to work on it is limited at this time. We haven’t given up.

VersaTune-Express Receiver assembly
Software work continues. Hardware is ready pending revisions due to software testing. The Raspberry Pi computer board is now available as are most other components but I won’t order anything until the software is proven. Software is functional but adding the DiSEqC function has become a challenge. I won’t proceed further until I can test the DiSEqC function as it may alter some hardware. All software is done using Java in the Rasperry Pi 2B processor so if there is anyone out there with Java experience, we’d like to see if you can help. Thanks for supporting us.

VersaTune-Express Receiver assembly
Work continues with software development but talent availability is limited so it takes time. New challenges present new ways to enhance and improve performance but sometimes that’s 2 steps forward and one step back. A new way to extract tuner data allowed us to scan and display data faster. This discovery allowed new features to be added. Also, supply chain issues still plague us. The processor powering this product is a Raspberry Pi model 4B which is not available in production quantities at this time. The RPI Foundation promised us production will ramp up in August 2023 so we are waiting. We DID have a prototype to show at Hamvention this year but it was for show only, not a working model. For those of you patiently waiting, our best prediction for availability is mid to late fall this year. We will continue to post updates. Thanks for your understanding.

VersaTune-Express Receiver assembly
We are still working on perfecting the VersaTune software. Progress is slow due to software engineering availability. The basic code is complete but there are many bugs that need refinemant. The hardware is complete and 3 prototypes are available to de-bug the software but supply chain limitations prevent procuring production quantities of parts. Stay tuned as work is progressing. For those in the USA, I am going to demonstrate a working model at the Dayton, Ohio Hamvention on May 21 2023 in the ATV Forum.

VersaTune-Express Receiver assembly
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 with open source software optimized for repeater operation at a very attractive price. Working prototype models for testing have been produced but because of supply chain limitations, sufficient parts are not available for production.The heart of the unit will be an included Raspberry Pi model 4B but that will not be available until next year. We are planning to showcase the unit at HamCation in Orlando, Florida next February if parts will become available. Stay tuned for up-to-date information.

MiniTiouner-Express Receiver Assembly
As of September 2021, MiniTiouner sales have slowed to the point where is is not worthwhile to produce more assemblies so MiniTiouners are no longer available. 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
