More Info on Tom's Amazing Junkbox 20 meter Receiver (using FPGAs)

 

Back in June we had a post about an amazing junkbox receiver project carried out by Tom in SW England:

This was a receiver built around SBL-1 mixers and 10.7 MHz filters salvaged from an old satellite receiver.   It was also the first radio receiver project undertaken by Tom.  His use of FPGA technology is especially interesting. 

We asked Tom for more info and he kindly provided it:

Tom also sent me Firmware sourcecode  that may be reusable for STM8 users, and the FPGA design file (for Quartus users). If anyone has a GitHub or similar site that can host these files, please let me know and we will send them to you.
