What Good is a Radio if You Hear Only Distortion!
We all know what I’m talking about. You plug your MP3 player into your Marine Radio and turn up the volume. Maybe the first couple of lines don’t sound too bad, but eventually you will hear that horrible crackle and you know the singer on your MP3 doesn’t have a raspy throat – your speakers have failed! Do yourself and your friends a favor and shop smart when you install your speaker system. Don’t try to cut here. Speakers will either make or break your system. Your listening pleasure will be nearly non-existent and your favorite song will take a giant step backward.
Good marine speakers incorporated with good marine subwoofers is the correct combination you should shoot for – you’ll not be disappointed. After all, who wants to do a job twice – once just to get it done, and then again to install the correct equipment that should have been put in, in the beginning?
Why Does my VHF Radio Work?
If you ever have wondered just what is VHF and how does it work, maybe we can shed a bit of light on this today. VHF frequency falls between HF (high frequency) and UHF (ultra high frequency). VHF radios have a precise area of broadcast because the ionosphere doesn’t usually reflect the signal very much beyond its immediate surroundings. Because of this fact, for reaching a target in close vicinity, you can’t beat a VHF radio. It doesn’t interfere with other broadcasts in the near vicinity.
There is, however, a disadvantage to VHF frequency – some land features will block its signal. On the other hand, VHF users don’t have to be concerned with signals being obscured by buildings or distorted by naturalistic sounds in the atmosphere or by conflicting signals from nearby equipment.
