Glossary

AM

Amplitude Modulation (Encode low-high sound by varying output power less or more)

CB

Citizen's Band ~27 MHz

CTCSS

continuous, tone-coded squelch system

FM

Frequency Modulation (Encode low-high sound by deviating the transmit frequency lower or higher)

FRS

Family Radio Service (Blister pack, Walmart, low power, camping UHF radios. Fixed antenna.)

GMRS

General Mobile Radio Service (FCC family license, high power, UHF radios. Repeaters allowed.)

HF

High Frequency 3 - 30 MHz

LSB

Lower Side Band (left half of AM signal with carrier suppressed. Used by Hams below 10 MHz.)

NVIS

Near Vertical Incidence Skywave

PL

Private Line (Motorola proprietary term for CTCSS, not "private")

PTRS

Pine Tree Radio Society

SSB

Single Sideband (half of an AM signal with the central carrier suppressed. Commonly Upper Sideband, except Ham voice below 10 MHz.)

UHF

Ultra High Frequency 300 - 3000 MHz

USB

Upper Side Band (right half of AM signal with carrier suppressed. Used by Hams above 10 MHz and everyone else everywhere, including digital.)

VHF

Very High Frequency 30 - 299 MHz
