boatbod op25 with two rtlsdr

[gariac]

I have two rtlsdr with different SN:

rtl_test
Found 2 device(s):
0: Realtek, RTL2838UHIDIR, SN: 00000002
1: Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM
Found Rafael Micro R820T tuner

This is the stock p25_rtl_example.json. Everyone should have it but for completeness here it is.

{ "channels": [ { "name": "Voice_ch1", - Pastebin.com

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

I have managed to set up json files for two different systems (that is one at a time) using
p25_single_rtl_example.json as an example. Here is the relevant part of one on the json files which some will recognize at the Silicon Valley police trunk system:


"trunking": {
"module": "tk_p25.py",
"chans": [
{
"#nac": "0x1F1",
"#wacn": "0xBEE00",
"#sysid": "0x5E4",
"sysname": "Trunked System",
"control_channel_list": "771.85625,72.15625,772.30625,772.45625",
"whitelist": "",
"tgid_tags_file": "",
"rid_tags_file": "",
"tdma_cc": false,
"crypt_behavior": 2
}
]
},

I have an additional "chans" for the East Bay RCS.

Is there a way to set up a json like p25_rtl_example.json for two different rtlsdr with two different audio streams?

Yes, it's possible.

Will the two streams be built from two whitelisted sets of tgids that are part of the same trunked system, or is the second stream from a completely separate trunked system? Let me know which, and I'll point you in the correct direction.
