Hello Scott, I've seen attachment on the list already, graphic files and .grc files too. It would be very nice, if you could post your .grc files to the list.

Note to all who are inquiring — I haven’t messed with this stuff since March. The examples I have shown used version 3.7.5.1 — if there are newer versions since then, no guarantees! -Scott K5TA On Sep 9, 2015, at 9:21 PM, Bntyhunter wrote: > Hi, > > I would like to see the screenshot or if you feel like it, the flowgraph. > Thanks! > > > > On Wed, Sep 9, 2015 at 9:46 PM, Scott Davis wrote: > I don’t think this list is attachment-friendly, so I’ll send a screenshot of > my 2m Rx flowgraph to your email address.

Re: [Hackrf-dev] Amateur radio with HackRF One and gnuradio
I don’t think this list is attachment-friendly, so I’ll send a screenshot of my 2m Rx flowgraph to your email address. Don’t panic -- it’s way more complicated than you need for starters. I was looking at 3 FFTs — RF, IF and audio, and I included an audio band-reject filter to get rid of CTCSS tones from repeaters. Also had a variable RF gain control, a channel selector and a simple variable squelch. However, the basic “Hello world” ought to work fine if you just change the frequency to your target, and replace the WBFM receive block with an NBFM receive block at 5kHz deviation. Maybe that’s what’s causing your distorted audio…? -Scott K5TA On Sep 9, 2015, at 3:45 PM, R. Niles Vaught wrote: > Thanks for the replies and info.

Re: [Hackrf-dev] Amateur radio with HackRF One and gnuradio
Thanks for the replies and info. Hello world with broadcast FM works and sounds great. VHF/UHF specifically poor audio on rx; the voice is there but sounds terrible. I haven't tried any tx yet. Scott would you be willing to share your flow graphs for 2m and 70cms? And Chuck, I do have the ham-it-up adapter; once I have VHF/UHF working I'll look at that. 73!

[Hackrf-dev] Amateur radio with HackRF One and gnuradio
Hello all, I am looking for either previously constructed or very generous hints on how to construct gnu radio blocks to receive and transmit FM signals on the VHF UHF amateur radio bands using HackRF One. I have completed the available tutorials from Michael with success, but my personal attempts to use HackRF One and gnu radio on the ham bands have resulted in very poor audio.
