Welcome to /hamradio/

Quanshengs/Baofengs/Tytera, are all radios that are known to emit spurious signals/ desensitize/ and be of inferior quality. I beg of you, if you are going to go cheap, do yourself a favor and get yourself a 2nd hand radio from a reputable manufacturer. Pay once, cry once.

it's a VHF/UHF handheld radio, unless you manage to work satellites, you will not be doing more than line of sight at best.

It is not a HF radio for global communications.

A cheap shortwave receiver will give you the ability to hear foreign commercial broadcasting.

Spend a bit more and you can also receive SSB, and then you can listen to amateurs, various militaries, decode digimodes and other utility stuff. >>327

What's the consensus on AM / FM radio threads being posted here?

I planned on making a post over starting a really shitty low-power AM music station
