I am located in San Antonio, Bexar, Texas. Using a baofeng bf-f8hp. Mainly wanting to monitor local police, emergency channels
Looking at Bexar County in the
database, there is very little that you can monitor with that radio. It's not a trunking radio, which is what you need for that area, and can only receive Vhf-high or Uhf channels. While there are a few listed for your county, the majority of public safety users (fire/police/ems) are on this trunked system:

Some of the smaller cities are on the LCRA
system.
The San Antonio/Bexar County system is EDACS with ProVoice, so you would need one of the Uniden scanners that can be upgraded for ProVoice. That system is also on 800MHz, which is also beyond the capabilities of your Baefong.
The LCRA system is digital (your radio is analog only) and also uses 700 & 800MHz frequencies (again, which your radio cannot handle).
If you try and program some of the few Vhf or Uhf frequencies, be absolutely sure that you do not try and transmit on them (your radio is capable of that). That will buy you more trouble than you can stand if transmitting.
