Decode errors? There's no Encryption Algorithm “32” in Decimal or Hexadecimal, and the Key ID and Message Indicator are both zero. ADP would be Algo 0xAA (Hex) or 170 (Dec). See table below. ALGIDs 0x00, "ACCORDION 1.3" , 0x01, "BATON (Auto Even)" , 0x02, "FIREFLY Type...

Wow! That sounds more serious than the frontend without so much of a hint of your signal generator at -60 dBm. LO? Have you tried injecting a known signal on any of the other bands?

Bill, That link is for the Raspberry Pi Operating System (OS). I was referring to the particular Linux software application that was built/installed on the Pi to stream the audio from your scanners/receivers to BCFY in an effort to offer assistance with the configurations to avoid feed...

Bill, What software was installed on the Raspberry Pi to stream the feeds? Are you sending any tags BCFY?

Bill, I routinely run multiple BCFY P25 TRS feeds using op25 on a Raspberry Pi-4 with no difficulties. Can you elaborate on what your setup consists of exactly? Another Bill

No such adjustment. You may need to set CQPSK if the PD is using simulcast, else radio needs repair/alignment.

It looks like a loss of USB connectivity with your SDR dongle. Check that your SDR's USB connections are mechanically and electrically secure and don't overlook the SDR itself or a faulty USB hub or extension cable(s) if used.

Here's a great source to look up aviation communications and weather broadcast frequencies. I believe that most if not all airports having AWOS/ASOS facilities also offer local dialup telephone access.

I simply used your JSON in loading seram-capture.bin without use of any talkgroup filters. I did quickly script a tag file for use in identifying the captured talkgroup activity. I even received a transmission (French) during my playback. Are you certain the raw symbols dump posted were...

@MTL_Emergencies, I downloaded and ran your raw symbols dump on GR-3.8 (Master Branch) and on GR-310 (GR-310 Branch) but was unable to duplicate the empty voice channels. Perhaps the symbols dump was terminated before the problem you describe occurred as there were only a little over 2K tsbks...

Multiple instances of rx.py or multiple instances of muti_rx.py? You do need to assign unique file names when running multiple instances and different or unique labels for multiple receivers, devices, and etc. within you JSON files used to run mult_rx.py. It would be helpful to your configs...

That's correct. You have to blank the "module" itself.

Be patient. It will take several minutes from the initial boot up of a fresh Pi-Star image before the AP is configured and up to where it becomes visible when scanning for Wi-Fi networks from your PC.

You're going to have to get network access in order to enter configuration parameters being that you flashed the HS with a fresh Pi-Star Image. By default, the Pi-Star software will enable a WIFI Access Point (AP) that will become visible when scanning for wireless networks using your PC. Find...

Setting "module" to blank prevents your JSON from opening sockaudio.py. This is necessary when using Liquidsoap to avoid conflicts in that the source input() function contained in the LIQ script calls audio.py that in turn imports sockaudio.py. You still have the option of using local speaker...

To be clear, what are exactly do you mean by "Empty Voice Channels? Enable logging verbose (-v 11) to capture additional details to post with your problem description.

An SDR's usable bandwidth is never as great as the sampling rate whereby there is a roll off in sensitivity as your approach the lower and upper ends of the sampled spectrum. The frequency error observed in your video capture appears excessive! I would suggest dropping the sample rate to...

Can you post your SERAM json file?

I am using Liquidsoap to feed my private streams as well as to save mp3 audio archives to an Apache server that are set for auto deletion after seven days. Very handy tool!

Liquidsoap accepts (receives) UDP audio packets from either rx.py or multi_rx.py applications.
