Don't let it get you down. There's a lot of things to learn when you're starting out in radio. If you're looking to monitor a frequency, you need to know a few things about it. 1. the frequency-this may be a single frequency (conventional), multiple conventional channels used for different needs or multiple channels used in a trunking system. 2. Is it analog or digital? If digital, what type? P25, DMR, NXDN, iDAS, etc. 3. Is it "in the clear" or encrypted? If encrypted, give up now. Once you have those answers, the next question is; how am I going to listen? If you're looking for a base to monitor one channel or system, the dongle suggestion above is probably your best bet as it can decode many of the digital modes as well as analog. If you need a portable solution, you'll need to look at scanners with the frequency range and capabilities you require. Uniden is scheduled to make an announcement tomorrow that many are speculating that they will have a firmware update that allows DMR decoding, but as of right now, the only digital mode scanners will receive is P25. for any of the other modes, you would need to buy a portable radio capable of the mode. If it's a trunked system that's not P25, even a portable capable of working on the system won't work as it has to be authenticated onto the system by the administrator. I know it's a lot, but the more you learn, the easier it gets.
