Re: [Hackrf-dev] Replacing the LNA/PA
Robert, are you looking to fix a broken HackRF or are you re-designing it to eliminate the use of an obsolete part? If its the former, the part is still available and if history is any guide it will continue to be available in piece parts and lots of various sizes for several years. --Chuck On Sat, Feb 17, 2018 at 10:18 PM, Robert Chadwick via HackRF-dev < hackrf-dev@greatscottgadgets.com> wrote: > Sorry if this is a duplicate. > > Looking at the schematic, it appears the HackRF uses a MGA-81563 for the > LNA and PA.

Maybe you could slightly improve noise figure with a better amp, but prolly not worth the trouble. ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
[Hackrf-dev] Hack RF One - Ok or not?
A question I would like advice on please. I have some basic C and Fortran but no python. I have bought a Hack Rf One. I might buy more if I can this one working. From hackers_info on my terminal I get hackrf_info version: unknown libhackrf version: unknown (0.5) Found HackRF Index: 0 Serial number: a06063c82520485f Board ID Number: 2 (HackRF One) Firmware Version: 2015.07.2 (API:1.00) Part ID Number: 0xa000cb3c 0x00504764 on my iMac. Is this ok or is my Firmware and librhackrf out of date and how do I fix that? Many thanks. ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev

A good source of info on this is the hackrf wiki : https://github.com/mossmann/hackrf/wiki/Updating-Firmware The latest releases are here: https://github.com/mossmann/hackrf/releases Updating the firmware requires no coding, just running the tools. --Chuck On Sun, Feb 18, 2018 at 12:27 PM, Robert Edwards wrote: > A question I would like advice on please.
