The WinterHill receiver project by Brian G4EWJ with hindrance and occasional help from Mike G0MJW. It uses the BATC '''[[Advanced receiver hardware]]'''.

==Features==
 
 
 
•        WinterHill is a 4 channel DVB-S/S2 receiver based on the BATC Advanced Receiver PCB
 
 
 
• The main components are a Raspberry Pi 4 (RPi4), 2 x FTS433x NIMs, 2 x PICs and 2 optional LNB PSU boards
 
 
 
• The PICs are programmed in-circuit automatically during software installation
 
 
 
• The RPi4 software is based on LongMynd by M0HMO
 
 
 
• The RPi4 interfaces to each NIM using a PIC, rather than an FT2232H USB module
 
 
 
• The 4 received transport streams (TS) can be sent to any location using UDP protocol
 
 
 
• Transport streams are displayed either locally or remotely using VLC
 
 
 
• Receive commands can come from various sources, including QO-100 LiveTune designed by M0DTS
 
 
 
• The highest symbol rate is limited by the speed of the serial connections between devices and is about 10M bit/s per NIM. E.g. the QO-100 beacon at SR1500 FEC4/5 (2.4Mbps) and a terrestrial repeater at SR4000 FEC7/8 (7Mbps) should be OK. 
 
 
 
• Currently, the lowest symbol rate that can be received is 66kS
 
 
 
• WinterHill is named in memory of Brian G3SMU, who was a huge presence on ATV and microwaves from his Winter Hill QTH in Lancashire, North-West England
 
 
 
== Timeline==
 
 
 
December 2020 - Currently the project is at the design phase with a proof of concept receiver working on breadboard hardware.
 
 
 
February 2021 - beta testing in progress
 
 
 
March 2021 - First production PCBs expected
 
 
 
==Hardware==
 
 
 
The PCB design by Mike G0MJW is based on a completely new concept, BATC Advanced DATV Receiver, supporting two SERIT tuners with an integrated Raspberry PI4 and PICs. No USB module is required. This supports 4 simultaneous receivers in either a set top box mode, with the PI desktop, or headless, or a combination of these.
 
 
====Version 0.1====
 
 
 
Feasibility design which worked fine
 
 
 
====Version 0.2====
 
 
 
A prototype that was also built by several beta testers. Two pin programming jumper instead of 3 pin and didn't fit in the box.
 
 
 
====Version 1====
 
 
 
First general release PCB - Likely release March 2021
