How does the weather affect HF radio signals?
How does the weather affect HF radio signals?
Given that many users of HF radio – for military communications or humanitarian needs, for example – operate in extreme environments, there may be more than just rain to contend with.
Are there any receivers for National Weather Radio?
There are many receiver options, however, ranging from handheld portable units that just pick up Weather Radio broadcasts, to desktop and console models which receive Weather Radio as well as other broadcasts. NWS staff produce Weather Radio broadcasts. NWS neither manufactures nor sells receivers.
Where can I get a weather radio in Canada?
Environment Canada, which includes the Canadian weather agency, operates weather radio transmitters that generally operate on the same frequencies as the U.S. NOAA Weather Radio network. For information on Weather Radio receiver recalls, go to the U.S. Consumer Product Safety Commission web site and choose “Radios Weather” in the product type list

Can you get weather radio on AM radio?
The broadcasts cannot be heard on a simple AM/FM radio receiver. There are many receiver options, however, ranging from handheld portable units that just pick up Weather Radio broadcasts, to desktop and console models which receive Weather Radio as well as other broadcasts.
What are the rules for reflection in radio waves?
The rules that govern the reflection of radio waves are simple and are the same as those that govern light waves. When a reflection occurs it can be seen that the angle of incidence, θ1 is the same for the incident ray as for the reflected ray. Additionally there is normally some loss, as a result of absorption, or signal passing into the medium.
