  • Hand-held radios (aka HTs, portables)

    • Very portable

    • Limited range

    • Better range with outside antenna and amplifier

    • Cost (new) ~ $100 - $580 depending on features

    • The simpler, less expensive sets are easier to operate

  • Types of hand-helds

    • Single-band (probably 2 meter, 144-148MHz)

    • Dual-band, one-at-a-time (2 m & 70 cm)

    • Dual-band, two-at-a-time (2 m & 70 cm)

    • Tri-band

  • Other factors on hand-held radios

    • Antenna: usually a “rubber duck” with set

    • Antenna connector: BNC or SMA types are common; some sets don’t have one

    • Battery types: Alkaline non-rechargeable, or NiCd, NiMH or Lithium rechargeable

    • Rechargeable batteries lifetime ~1-2 years

    • Snap-off batteries are a convenience

    • Most sets will receive out-of-band, may have wx

    • Case size considerations: tiny to large

    • Be cautious if buying used

      • Portables get dropped!

      • Older sets may not have needed features (CTCSS)

  • Other factors on mobile radios

    • Antenna: not supplied with set

    • Antenna connector: “UHF” connector

    • Power source: 12VDC auto supply or converter (not supplied)

    • Most sets will receive out-of-band, may have special weather-band reception

    • Power levels: generally 50 to 75 watts out

    • Cautions if buying used:

      • Need to verify operation completely, but usually less risk than portables

      • Older sets may not have needed features (CTCSS)

  • Base station radios

    • Most stations adapt mobile radios for base

    • Greatest range, if good outside antenna used

    • Require power source and outside antenna

    • Cost (new) like mobile sets, plus power supply and antenna

    • 120VAC to 12VDC Power supplies ~ $100

    • Can use storage battery with trickle charger; this also provides emergency power. But lead-acid batteries need servicing and have some inherent dangers, and only last 2-3 years.

    • There’s only one true base-station radio marketed today: Icom IC-910H, ~ $1279.
