Gmrs who can use
GMRS - who can use?

  • The General Mobile Radio Service (GMRS) is a land-mobile radio service available for short-distance two-way communications to facilitate the activities of an adult individual and his or her immediate family members, including a spouse, children, parents, grandparents, aunts, uncles, nephews, nieces, and in-laws

  • Fees: $75 for 5 years to FCC


Gmrs what can you use
GMRS – what can you use?

If you operate a radio that has been approved exclusively under the rules that apply to FRS, you are not required to have a license. FRS radios have a maximum power of ½ watt (500 milliwatt) effective radiated power and integral (non-detachable) antennas.

If you operate a radio under the rules that apply to GMRS,you must have a GMRS license. GMRS radios generally transmit at higher power levels (1 to 5 watts is typical) and may have detachable antennas.


Citizens Band

Been around for years

Antennas very inefficient on portables

Most conversations not fit for family consumption!

Bad choice for ballooning

  • Operation of an amateur station requires an amateur operator license grant from the FCC. Before receiving a license grant, you must pass an examination administered by a team of volunteer examiners (VES) to determine your operator class.

  • Fees: None to FCC


Amateur radio1
Amateur Radio

  • Bands of interest are VHF and UHF, can be high power (5 watt portable, 50 watt mobile)

  • Either is fine for ballooning

  • Equipment relatively inexpensive

  • Can be used for telemetry - GPS tracking, TV and other fun stuff

  • Can set frequencies to avoid conflicts

  • Can go through repeaters to increase range

  • Must have licensed “ham” at BOTH ENDS!


Commercial
