-**Weather reports** have been an important part of radio usage since Day 1. They now play a hand in guiding travel patterns, agriculture and commerce. Nowadays there are all sorts of ways to get weather updates and alerts off of radio waves, including with a television and your cell phone. Even much of the weather data you read on the internet, only reaches it after first traversing through radio waves. **Big Weather doesn't want you to know this, but with //simple VHF technology//, you can get this lucrative data //anonymously & for free!//**+**Weather reports** have been an important part of radio usage since Day One.

 Since weather radio is a very broad category of radio, where to find weather reports on the spectrum varies from region-to-region. In most places, you can find it on the popular AM/FM and TV stations. However, more raw forms of the data can be found in other places. Since weather radio is a very broad category of radio, where to find weather reports on the spectrum varies from region-to-region.

-The seven frequencies, commonly referred to as **WX1-WX7**, do not actually go by those names. They are just labels that manufacturers use, and the frequencies they are assigned to vary between units. The frequencies are as follows:+The seven frequencies, commonly referred to as **WX1-WX7**, do not actually go by those names. They are just labels that manufacturers use, and the frequencies they are assigned to vary between units //(what some call "WX7" others will call "WX1")//. The frequencies are as follows:
  
   * **162.400 MHz**   * **162.400 MHz**
Line 23: Line 23:
   * **162.550 MHz**   * **162.550 MHz**
  
 +Each NOAA local broadcast station operates on one of these overlapping frequencies, so that no two neighboring stations share the same frequency. The way that this is set up, is a North American resident will be within range of at least one station operating on any of these seven frequencies at any given moment.

-The Canadian Coast Guard runs a service known as the **continuous marine broadcast**, on five nearby frequencies overlapping the shore-broadcasting channels from the marine VHF band:+The Canadian Coast Guard runs a service known as the **continuous marine broadcast**, on five nearby frequencies overlapping five shore-broadcasting channels from the marine VHF band: 
 + 
 +  * **161.65 MHz** (Marine VHF Channel 21B) 
 +  * **161.75 MHz** (Marine VHF Channel 23B)

 +  * **161.85 MHz** (Marine VHF Channel 25B) 
 +  * **162 MHz** (Marine VHF Channel 28B)

 +This is for **marine weather** on the coasts and lakes specifically, as well as other important notices for mariners and sea freighters. These same alerts also get played on some of the main seven frequencies above. Sometimes they are referred to as **WX8-WX12**, which like the other "WX" designations, is unofficial. Regardless, these five extra channels are sometimes included on weather radios.
