Frequently Asked Questions

CTCSS/DCS codes keep your squelch closed to other users, but they are not encryption. For true privacy choose a digital system with proper encryption features and manage keys carefully.

Yes if you keep to the same standards. On analog, match frequencies and tones. On DMR, match color codes, time slots, and talkgroups. Features like encryption and text may be brand specific, so plan your feature set accordingly.

Yes, if both radios share the same frequency, channel, and signaling codes. Otherwise, they are incompatible.

RSMs for loud zones, noise-reducing headsets where required, and multi-bank chargers staged by department. Consistent mic distance improves intelligibility more than model names do.

As few as possible to mirror real workflows: a site-wide, emergency, and 3–5 role channels/talkgroups cover most operations. Over-choice slows response.

CTCSS/DCS (“privacy codes”) only quiet the squelch. For real privacy, use digital with encryption and manage keys carefully. Keep sensitive details off SITE.

RSMs for yard/security, earpieces for office/admin, and multi-unit chargers in key rooms. These improve intelligibility and readiness without changing radios.

Use earpieces and, if needed, digital with encryption for sensitive traffic. Keep private details off the SITE channel.

As few as possible to cover real workflows. Many shows succeed with SITE, OPS, SECURITY, MEDICAL, BOX, F&B, AV/TECH, EMERGENCY—then prune if something is unused.

No. CTCSS/DCS only control when your radio opens squelch. For real privacy, choose digital with encryption and manage keys.

Use the manufacturer’s programming software or keypad entry to assign frequencies, channels, CTCSS/DCS tones, and features according to your business license and communication needs.

Analog radios usually are not. Digital radios may support encryption for secure communication, depending on the model and system.

As few as possible to cover real workflows often 6–7 total including SITE and EMERG. Keep names short and consistent across all radios.

Keep transmissions short and clear, use standard radio etiquette (listen before talking, avoid interrupting), and identify yourself or your unit at the start of each message.

A walkie-talkie is a type of two-way radio designed for short-range, portable communication, often handheld and used without external antennas or base stations. "Two-way radio" is a broader term that includes handheld units, mobile units in vehicles, and base stations with varying ranges and power levels.

Push-To-Talk: the button that switches the radio from receive mode to transmit mode.

UHF is usually best indoors because it penetrates racking and walls more effectively. If your operation includes large outdoor yards or open land, test VHF for those areas—but expect to prefer UHF inside.

Limited range, susceptibility to interference, need for FCC licensing on certain bands, and generally lower audio quality compared to modern digital communication tools.

Select the correct channel, press PTT, identify yourself, deliver a clear message, and release PTT to listen for a reply.

Some advanced digital radios (DMR, P25, TETRA) include built-in GPS for location tracking, but basic models typically do not.

For harsh or outdoor work, pick IP67. For typical indoor use with occasional wipe-downs, IP54/55 can suffice. If in doubt, go higher.

Plan for a full shift plus buffer (10–14 hours typical). Replace packs on an 18–30 month cycle and keep labeled spares at key locations.

Most fleets replace lithium-ion packs every 18 to 30 months depending on duty cycle and charging practices. Track purchase dates and retire packs that show shortened runtimes or cause distorted audio on transmit.

Only if your scope includes flammable atmospheres or the owner/GC requires IS. When required, use IS-certified radios and IS accessories—no exceptions.

Electromagnetic waves in the frequency range of 3 kHz to 300 GHz, used for wireless communication, including two-way radios.

Neither is “stronger,” but VHF travels farther in open areas, while UHF penetrates buildings and obstacles better.

Antenna, speaker, microphone, PTT button, display/control panel (if present), battery, and internal transceiver circuitry.

FRS radios and CB radios can be used without an FCC license in the United States.

Depends on environment: VHF for open/rural areas; UHF for indoor/urban settings.

Common categories: whip (omnidirectional), dipole, Yagi (directional), and parabolic (high-gain, focused).
