3-30 MHz = HF (shortwave) 30-300 MHz = VHF 300-3000Mhz = UHF Antennas on cheap Baofeng radios are not great for VHF. Listings below are (roughly) in order of low-to-high frequencies (with a few exceptions to keep similar things together).
## CB (Citizens Band) ~27 MHz
## Portland neighborhood channels 147.5800 NET-Tac 1 PDX Emergency Management 146.4600 NET-Tac 2 PDX Emergency Management
431.x00 (for x=1-7) PDX NET
## MURS (Multi-Use Radio Service) Five channels, use permitted ≤2W without license: 151.82 MHz 11.25 kHz MURS 1 151.88 MHz 11.25 kHz MURS 2 151.94 MHz 11.25 kHz MURS 3 154.57 MHz 20.00 kHz Blue Dot 154.60 MHz 20.00 kHz Green Dot
## Weather (USA / NOAA)
National Oceanic and Atmospheric Administration maintains NOAA weather radio stations 
all over the U.S. They seem to use seven specific frequencies that they refer to as "channels" 1-7:
162.400 [1]
162.425 [2]
162.450 [3]
162.475 [4]
162.500 [5]
162.525 [6]
162.550 [7]
There is supposedly a Portland/Estacada station at Channel 1. Only Ch 7 seems to work in SE PDX.
## GMRS (General Mobile Radio Service): Also 462.xxx (shared with FRS) and also 467.xxx. License costs $35, no exam.
## FRS (Family Radio Service) Free to use (wattage limitation), no license. Shared with GMRS. 462.xxx
