The Knucker project is to develop a variable bandwidth DVB-T USB receiver and transmitter for use on the lower VHF bands and HF. It will also have applications for mobile stations on 437MHz and above.
December 2020 - Currently the project is at the design phase with a proof of concept receiver working on bread board hardware. Despite having hardware we are a long way off having even a beta release so don't ask!

Receiver
Hardware
The PCB design by Mike G0MJW is based on the MiniTiouner Version 2 board - the photo shows the first porotype built and tested.
BOM and schematics are available here: File:Knucker.xlsx
Software
It is intended to develop a core DVB-T receiver application which will be integrated in to the LongMynd Linux based receiver.
It is envisaged that a set top box version of the code will be developed using the RydePlayer and will be known as the Knucker receiver.
It is also planned that the Portsdown DATV system will be enhanced to include the DVB-T receiver.
Transmit
DATVexpress
Applications
DX!!
DVB-T can be used in environments where phase distortion and multi-pathing means DVB-S does not work. Typical applications include mobile video transmissions and bands below 70MHz :-)
