Coming Soon: KN0CK Rev B Integrated HF RTLSDR

Marty KN0CK developed a very interesting v1.0 HF converter based on surface mount technology that fits inside the casing of an RTLSDR tuner dongle. He’s recently sent me schematics for the revision, which should offer even better performance!

This new iteration has a few major upgrades from the previous – an ESD protection diode on the input, and an optional Mini-Circuits MAR 8+ RF preamplifier which should really draw out some weak signals. Nice weather is coming up soon and once I have some free time, I’ll string up my long antenna – this should really pick out the weak shortwave signals I love hunting for.

    > I’ll be offering KN0CK’s converters for sale soon

    Does it mean the details (schematics, etc.) won’t be freely available ? No complain, just a question.

      Hi Larry,

      I expect there will be a schematic and (maybe) even a board mask available but we’re still hashing out some of the details. I sure wouldn’t want to solder 0402 SMD myself onto the piggyback board, though!
