How far do ham radios reach?
Even though Ham radio has more inherent range than other options like the FRS walkie talkies, the popular 2m and 70 cm bands available to Technician-level Hams are generally limited to line-of-horizon or line-of-sight range. If you’re using a handheld unit, you may only get 1-2 miles.
Are ham radios dangerous?
It has been known since the early days of radio that RF energy can cause injuries by heating body tissue. In extreme cases, RF-induced heating can cause blindness, sterility and other serious health problems. These heat-related health hazards are called thermal effects.
Can a ham use GMRS?

All radios use the same airwaves, so in theory, a ham radio should be able to connect to a walkie-talkie. But it’s the same principle as a ham radio and a CB radio, illegal for ham radio to connect with walkie-talkies because of the imbalance in power level.
Can a radio signal be traced?
A tracking transmitter broadcasts a radio signal which can be detected by a directional antenna (typically a Radio Direction Finder.) By rotating the antenna one can determine the direction the signal lies in and of course whatever it may be attached to. The EPIRB is an example of a similar device.
What is Ham Radio APRS?
Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area.
