Firstly, we need to know what city in Newton County your wanting to hear.
Secondly, Sheriff, and city of Newton now are on the MSWIN and you can NOT do that on an Baofeng radio. https://www.radioreference.com/apps/db/?ctid=1447 To monitor that, you need a REAL scanner that can do 700 MHz, and is P25 Phase II capable, such as the Uniden BCD436HP, BCD536HP, SDS100, BCD325P2, BCD996P2, or Whistler TRX-100, TRX-200, TRX-1, TRX-2, WS1098 etc.... The other municipalities you would need to know the tone in use to properly program them into your Baofeng HT. We have not had anyone do any submissions with the current tones in use so your out of luck there. Also, it is highly likely that they all are transitioning to use of the MSWIN since County and Newton already are on it.
As for programming you need the RX, and TX frequencies... For the repeaters we list, the RX is the repeater OUTPUT, the TX would be the repeater INPUT for your radio. You would need to set it to the 12.5 spacing, NOT the 25. Set to RX ONLY. You can leave the RX and TX tone empty, but will then get any broadcast on those frequencies from anywhere they are in use. So its rather important to put in the correct tones in use.
I run an RD-5R which is the DMR capable younger brother to your UV-5R. The programming of the analog part of the codeplug is identical in both radios.
Example: Newton County Sheriff VHF CH 1: In the Baofeng, RX would be 155.70000 with the tone 411 DCS N. TX would be 158.8950 not sure of the tone on input, but as your listening ONLY thats best left blank. I would set the squelch at 2.
*But this is no longer in use as they now use the MSWIN. ONLY Fire Departments and Emergency Management and EMS that use VHF or UHF for paging are allowed to continue use of those systems once MSWIN use is active. All other agencies must abandon all but MSWIN as primary operations. Thats an MWCC rule, that is set up to force full use of the MSWIN, but is bad for those that want to have an fallback system if MSWIN should ever fail.*
