I built a new Trunk Recorder system which uploads the unencrypted calls (MTO) from LMRN Site 38 Pontypool

Equipment List for Trunk Recorder System:
Trunk Recorder GitHub - robotastic/trunk-recorder: Records calls from a Trunked Radio System (P25 & SmartNet)
Odroid N2+ SIngle Board Computer ODROID-N2+ with 4GByte RAM – ODROID
Ubuntu Linux 22.04
NooElec NESDR Smart RTL-SDR (qty 2) Nooelec - Nooelec NESDR SMArt v5 SDR - HF/VHF/UHF (100kHz-1.75GHz) RTL-SDR. RTL2832U & R820T2-Based Software Defined Radio - NESDR SMArt Series - SDR Receivers - Software Defined Radio

Performance:
Linux top reports about 50% CPU utilization on the ODROI N2+ running Trunk Recorder on one site.
I'm running 4 digital recorders.
I installed the Ubuntu server distribution without graphical user interface, the ODROID is running headless (no monitor/keyboard/mouse)
Trunk Recorder works with P25, Smartnet, Conventional adn Conventional DMR
Each RTL-SDR can receive about 2 MHZ of VHF spectrum, so for LMRN I have 140-142, and 142-144 on each of the two RTL SDRs.
A more powerful desktop PC could have several more RTL-SDR receivers, each configured for a differetn 2 MHZ slice of the spectrum.

I'm seeing the following talkgroups on Site 38 Pontypool and Site 26 Sunderland.
The talkgroups without display names may be TG Patches.
Encrypted Talkgroups include Oshawa CACC and Toronto OPP which are in the metadata log.
