  • Compatibility & Configuration

  • Do “privacy codes” make my conversations private?

    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.
  • Can I mix brands in one fleet?

    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.
  • Can two-way radios communicate with other radios?

    Yes, if both radios share the same frequency, channel, and signaling codes. Otherwise, they are incompatible.
  • What accessories matter most on the floor?

    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.
  • How many channels or talkgroups do we need?

    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.
  • How do we keep conversations private?

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

    RSMs for yard/security, earpieces for office/admin, and multi-unit chargers in key rooms. These improve intelligibility and readiness without changing radios.
  • How do I keep FOH conversations discreet?

    Use earpieces and, if needed, digital with encryption for sensitive traffic. Keep private details off the SITE channel.
  • How many channels should I plan?

    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.
  • Will “privacy codes” keep others from listening?

    No. CTCSS/DCS only control when your radio opens squelch. For real privacy, choose digital with encryption and manage keys.
  • How to program two-way radios for business?

    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.
  • Are two-way radios encrypted?

    Analog radios usually are not. Digital radios may support encryption for secure communication, depending on the model and system.
  • How many channels should we have?

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

  • Do I need a license?

    Most professional business systems do. A license gives cleaner operation and supports repeaters and external antennas. Align your radio’s emission designators and bandwidth with the license.
  • What are the three use guidelines for two-way radio use?

    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.
  • What is the difference between a walkie talkie and a two-way radio?

    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.
  • What is PTT on a two-way radio?

    Push-To-Talk: the button that switches the radio from receive mode to transmit mode.
  • What is a two-way radio?

    A two-way radio is a communication device that can both transmit and receive audio signals, allowing real-time, back-and-forth conversations between users. Sometimes referred at a walky talky.
  • Manufacturing and Warehouse Operations

    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.
  • What are the disadvantages of two-way radios?

    Limited range, susceptibility to interference, need for FCC licensing on certain bands, and generally lower audio quality compared to modern digital communication tools.
  • How do you communicate on a two-way radio?

    Select the correct channel, press PTT, identify yourself, deliver a clear message, and release PTT to listen for a reply.
  • Do two-way radios have GPS?

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

  • What IP rating should I choose?

    For harsh or outdoor work, pick IP67. For typical indoor use with occasional wipe-downs, IP54/55 can suffice. If in doubt, go higher.
  • How long should batteries last?

    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.
  • How often should I replace radio batteries?

    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.
  • Do we need Intrinsically Safe (IS) radios?

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

  • Will more power fix our dead aisles?

    Usually not. Antenna height and placement beat watts. Extra power expands your interference footprint and drains batteries faster.
  • Why do my radios pick up other people’s conversations?

    You are likely on a shared or itinerant frequency or your CTCSS/DCS is disabled or mismatched. Program a unique tone or code for your fleet, or move to coordinated business frequencies. Digital systems with talkgroups also reduce unwanted traffic.
  • How far should my business radios work?

    Range depends on band, terrain, and infrastructure. Indoors with UHF portables you can expect coverage across most single buildings. Multi-building campuses often need a repeater or DAS. Outdoors in flat, open areas VHF can reach several miles line of sight. Height and antenna quality often matter more than raw power.
  • My audio is choppy. Is that a weak signal or a setting?

    Analog sounds noisy when weak. Digital often sounds robotic or drops syllables at the edge of coverage. First test with a fresh battery in a line-of-sight location. If choppiness remains in DMR, verify color code, time slot, and talkgroup. If you are scanning , confirm that scan list behavior is not causing missed words.
  • Other

  • What are radio waves?

    Electromagnetic waves in the frequency range of 3 kHz to 300 GHz, used for wireless communication, including two-way radios.
  • Should we choose analog or digital (DMR)?

    If you have light traffic and want simplicity, analog works well. If departments frequently overlap or calls get stepped on, DMR’s two time slots and talkgroups provide immediate relief and cleaner audio at the fringes.
  • Do I need a repeater for my event?

    If your venue is multi-story, sprawling, or has deep back-of-house areas, a single rooftop or mast-mounted repeater often makes coverage reliable. Small single-hall shows can run direct (simplex) without one.
  • What’s the quickest fix for “bad audio”?

    Swap to a known-good battery, tighten the antenna, remove the accessory to test the internal mic/speaker, and coach press-pause-speak with the mic 1–2 inches from the mouth.
  • Can vendors and subs use our system?

    Yes—give each subcontractor its own talkgroup/channel and control scan lists. Publish a simple radio etiquette sheet at onboarding.
  • Is GMRS better than CB?

    GMRS generally offers clearer audio, more privacy options, and longer range in some conditions. CB radios work without a license and are still popular among truckers, but GMRS can outperform CB for local communications.
  • Do I need digital (DMR) if my team is small?

    Not always. If calls rarely overlap and you value simplicity, analog works well. If traffic grows—or you hear stepped-on calls—DMR doubles talk capacity on the same license and usually cleans up fringe audio.
  • Do I need an FCC license for 2 way radio?

    It depends on the radio service. GMRS and amateur (ham) radios require an FCC license, while FRS and CB radios do not.
  • Can CB talk to GMRS?

    No, CB and GMRS use different frequencies and are not compatible with each other.
  • What about interference from wireless mics?

    Physically separate radio antennas from mic/IEM racks. Coordinate with AV on rigging locations and route radio coax away from power distro.
  • Will more power fix my dead zones?

    Usually not. Antenna height and placement beat raw watts. Extra power increases your interference footprint and can backfire in RF-dense venues.
  • Who is exempt from the GMRS fee?

    The FCC does not currently offer exemptions from the GMRS license fee for individuals.
  • Should we choose analog or digital (DMR)?

    Analog is simple and effective for small fleets. DMR adds capacity (two time slots), cleaner fringe audio, talkgroups, and options like unit IDs and encryption valuable for busy campuses.
  • Which signal is stronger, VHF or UHF?

    Neither is “stronger,” but VHF travels farther in open areas, while UHF penetrates buildings and obstacles better.
  • Can you get a GMRS license online?

    Yes, you can apply and pay for a GMRS license entirely online through the FCC’s Universal Licensing System.
  • What are the parts of a two-way radio?

    Antenna, speaker, microphone, PTT button, display/control panel (if present), battery, and internal transceiver circuitry.
  • Which radio does not require a license?

    FRS radios and CB radios can be used without an FCC license in the United States.
  • Can vendors and staff share the same system?d

    Yes—give vendors their own talkgroup/channel and limit what they can scan. Keep SITE for time-critical ops and EMERGENCY for command.
  • What is the best frequency for a two-way radio?

    Depends on environment: VHF for open/rural areas; UHF for indoor/urban settings.
  • How hard is it to get an FCC license?

    For GMRS, it’s straightforward: you apply online through the FCC’s system, pay the fee, and receive your license. There’s no test required.
  • Will a higher-power handheld fix coverage problems?

    Sometimes, but not always. Doubling power provides a relatively small improvement compared to raising the antenna, adding a repeater, or placing the user in a better RF location. Start with antennas and infrastructure.
  • What are the four types of antennas?

    Common categories: whip (omnidirectional), dipole, Yagi (directional), and parabolic (high-gain, focused).
  • Can friends use your GMRS license?

    Yes, your GMRS license covers your immediate family members, but not friends. Friends would need their own license to transmit legally.
  • Do police use GMRS?

    No, police use dedicated public safety radio systems on separate frequencies, not GMRS.
  • How far do CB radios reach?

    Typical CB range is 3–6 miles, though base stations and ideal conditions can extend range to about 15 miles.
  • Is GMRS better than ham?

    GMRS is easier to use and requires no exam, but ham radio offers much greater range, more frequency options, and worldwide communication potential.
  • How do we prevent stepped-on calls?

    Keep SITE for urgent, site-wide messages. Move coordination to role channels/talkgroups. Enable Busy-Channel Lockout and use short transmissions.
  • How far will GMRS go?

    Handheld GMRS radios can reach 1–5 miles, mobile units 5–20 miles, and repeater-assisted GMRS systems can exceed 50 miles.
  • What’s the quickest mid-shift fix for “bad range”?

    Swap to a known-good battery, check antenna tightness, remove accessories to test, and step toward line of sight. If multiple users report the same zone, move the antenna or add a temporary indoor antenna.
  • Do we need an FCC license?

    Professional business channels typically require licensing. Your vendor can coordinate licensed event-appropriate channels or provide access via a managed system.
  • What IP rating should we look for?

    IP67 is the sweet spot for harsh jobs: dust-tight and water-resistant. If conditions are milder, IP54/55 may suffice, but higher is safer on construction.
  • Why is audio muffled sometimes?

    Covered microphones, clogged mic ports, or speaking too close/far cause intelligibility problems. RSMs and consistent PTT technique fix most complaints.
  • Do we need an FCC license for school radios?

    Most professional systems do. Licensed business/industrial channels provide cleaner operation and allow external antennas and repeaters. License-free options exist for very small campuses, but power and privacy limits make them less reliable.
  • Will more power fix dead zones?

    Often no. Antenna height/placement beats watts, especially indoors. Extra power increases interference and drains batteries.
  • Should I choose VHF or UHF for a warehouse?

    UHF performs better through walls, steel, and racking. Choose UHF unless you have a specific line-of-sight outdoor requirement that favors VHF.
  • UHF or VHF—how do I decide?

    UHF usually wins indoors and on campuses; VHF can shine in wide-open outdoor sites. Borrow both and walk-test—a one-hour loop beats speculation.
  • Which band is best for construction?

    UHF is usually best inside structures and urban jobs. VHF can excel on long, open, horizontal sites. Test both if you’re unsure.
  • Analog or digital for a busy site?

    If you have more than two active, concurrent conversations or frequent stepped-on calls, DMR (two time slots on one repeater channel) pays off quickly.
  • Do truckers use GMRS or CB radios?

    Most truckers still use CB radios for road communication, but some are exploring GMRS for better clarity and range.
  • Do we need a repeater?

    If your building is large, multi-story, or has significant metal, a single rooftop or penthouse repeater often transforms reliability. Small, single-bay operations sometimes run direct (simplex) without one.
  • How much does it cost to get an FCC license for a radio station?

    For GMRS, the FCC license fee is $35 for 10 years. Broadcast radio station licenses can cost much more and vary depending on the service and application.
  • Analog or digital for a one-day festival?

    If you’ve got multiple active departments or a history of stepped-on calls, DMR is worth it. Two time slots on one channel reduce congestion and improve clarity.
  • What is the longest distance for a two-way radio?

    The maximum range depends on the radio type, power, antenna, and environment. Consumer-grade radios may reach 1–2 miles in urban areas, while high-power or base station radios can exceed 20–30 miles, and some systems using repeaters can reach hundreds of miles.
  • Are truckers switching to GMRS?

    Some are beginning to experiment with GMRS due to improved range and audio quality, but CB remains the dominant choice in trucking.
  • What’s the fastest fix mid-show for “bad audio”?

    Swap to a known-good battery, remove the accessory, and speak 1–2 inches from the mic after a one-second PTT pause. Check the antenna is tight and vertical.
  • Do we need a repeater or will handhelds be enough?

    If your project is multi-story steel/concrete or spans multiple buildings/laydown areas, a single high, central repeater often makes the difference between guesswork and reliable comms. Smaller, single-structure jobs can sometimes run direct (simplex).
