I assume your on a pet phase 2 system, do I would recommend using 2 of them and darkice to stream it. That is what I have in the station for our feed.I was thinking about hosting a live stream using raspberry pi 3b+ and op25 for my local fire dept. the department is p25 phase 2 i believe. how can i find out how many dongles will be needed prior to attempting this project?
thanks. how do i determine if 2 dongles are required? if one dongle can do the job, i hate to use 2.I assume your on a pet phase 2 system, do I would recommend using 2 of them and darkice to stream it. That is what I have in the station for our feed.

The number of dongles needed is tied to how many streams you want. If you're doing a mono (single channel) feed, then you only need a single dongle.I was thinking about hosting a live stream using raspberry pi 3b+ and op25 for my local fire dept. the department is p25 phase 2 i believe. how can i find out how many dongles will be needed prior to attempting this project?
That makes no sense, you need two. One to monitor the CC and one for the voice

Well maybe for you but it will not work on my county's system with just one. It always needs 2

I just don't see how it would be possible in my case since the CC is far from the voice channel so that's why I need two. The system you are listening to may be able to be listened to with one but some larger ones can't. I've don't this for 3 years and know for a fact I am unable to is 1I'm using only one dongle with OP25. Can you confirm you're using OP25 and not one of the other trunking software programs?

Have you updated the software in three years? It's possible that more recent versions reduced the requirement to one dongle.
I am also in Bucks county and am monitoring the P25 Phase 2 system with only one dongle. So yes it is possible.Well dam, I been using two. Now I'm wondering if it has been hindering the performance at all

You can have two plugged in but it'll only use one unless you're using multi_rx.py (and that doesn't work with P25 Trunking)Well dam, I been using two. Now I'm wondering if it has been hindering the performance at all

The reason you might need a second dongle with op25 is if the trunked system you are using is wide bandwidth than the capacity of your dongle.
For example, I use SDRPlay and Airspy dongles so I can get the entire site at once. An alternative would be 4 RTLSDR dongles, because the simulcast in my county is about 8Mhz wide.
I use TrunkRecorder, which uses OP25. https://wiki.radioreference.com/ind...d_Liquidsoap#Multiple_Streams_from_one_System
