You'll find the article describing this converter in the ARRL Handbook. Designed by W2DUC and K2YCO of the Rochester VHF Group, the same PCB can be used to build either a 50MHz or 144MHz version, with the IF at 28MHz.
This is the 50MHz version, with toroids. The 144MHz coils are open-core, wound on 1/4" 20tpi bolt.
