RECEPTOR VHF DE AVIAÇÃO-GR21-A.

This is a GR21-A model super regenerative aviation receiver. The schematic is in the online magazine "Eletrônica 21". It's a new magazine on the online market, and its first edition featured this air traffic monitoring receiver. This is an excellent receiver, very easy to assemble, with components that are also easy to find in stores or even in your scrap yard. It has great reception and sensitivity. I was given this virtual magazine as a gift by the magazine's director, and the way I found to thank him was by assembling the receiver and thus sharing its quality with friends. I have no connection whatsoever with the magazine; I am only giving my opinion as a reader in order to recommend this excellent receiver to fellow hobbyists. Those interested in the virtual magazine "Eletronica 21" featuring the GR21-A aviation receiver should contact Mr. Luis Antônio Côrtes Grillo via email ([email protected]) to arrange delivery details. Best regards to all, and good luck with your projects!
