Baofeng Uv-5rm+ help

Just got this today, trying to scan channels. The green light pops up, but no audio.

I figured I would skip the discovery scan and just program in documented stuff and do a scan through those.

I'm having a hard time figuring out how to save a frequency with a name.

In CPS (for ht1250) the tones are in DPL and TPL but I'm assuming they are a little different on these? I see a scan DCS mode and scan CTSCC modes. I have a scanner coming but just figured this would be fun to play around with.

Also is there a guide to sounds and what they represent? For example, this scanned frequency sounds like a diesel, or washing machine when its draining and spinning... I'm sure it means something? Lol

Digital signals. If it's intermittent it's probably one of the digital voice modes. If it's continuous then it's either a trunking control channel or some type of telemetry. UV-5R type radios are not capable of decoding digital audio.

Your radio can receive up to about 5-10 kHz +/- of the exact frequency so you need to know the band plan and proper channel steps to use when searching. If you know the exact frequency you can look it up here on RR or on the FCC database (if it's a non-federal user) and see what it is.

There used to be several web sites with digital mode sound samples to help identify what type of system it is. Try these.

Signal Identification Wiki

This wiki is intended to help identify radio signals through example sounds and waterfall images. Most signals are received and recorded using a software defined radio such as the RTL-SDR, Airspy, SDRPlay, HackRF, BladeRF, Funcube Dongle, USRP and other devices.
