https://github.com/TheButterZone/MacIntercom/releases/tag/v0.1.8-sdr I was frustrated with the lack of squelch options in CubicSDR (the ideal SDR software for me), which ended original development years ago. The best it seems to have is "auto-zero squelch" which sometimes breaks squelch with static, or ends up being so high dynamically that actual transmissions are seen on the waterfall but are squelched. So once I got WebRTC VAD in v0.1.8 just for Bluetooth, the v0.1.8-sdr feature release development flowed from that. Now a user can filter a raw, un-squelched in any way, radio frequency initially demodulated by their SDR frontend (which, even if recently-released, may still only have crude forms of squelch) and hear it through their system output with either VAD or CTCSS squelch. |
