Two-Way Radio FAQs | Buying, Compatibility & Support | Vitexacom

Straightforward answers to common questions about choosing, buying and using two-way radios and push-to-talk communication equipment from Vitexacom.

Choosing the right radio

What is the difference between VHF and UHF radios?

VHF and UHF operate on different radio frequency bands and suit different environments. The better option depends on the site, terrain, buildings, antennas and the system in use. Tell us where the radios will be used so we can help you assess the requirements.

How far can a two-way radio communicate?

There is no single guaranteed range. Performance depends on frequency, radio and antenna setup, transmit power, terrain, buildings, interference and whether a repeater or other infrastructure is used. Published range figures should be treated as indicative, not a promise of coverage at every site.

Do I need a radio licence?

That depends on the radio, frequency band and how it is configured and used. Some equipment is designed for licence-exempt use under applicable conditions, while other frequencies or systems may require authorisation. Check the product specifications and applicable South African requirements before operating a radio. Contact us if you are unsure.

What is the difference between analogue and digital radios?

Analogue and digital radios use different methods to transmit voice. Digital models may offer additional features, but radios must support compatible standards and configurations to communicate with one another. Do not assume that two radios will work together simply because they are from the same brand.

Push-to-talk over cellular (PTT)

How do PTT radios work?

Push-to-talk over cellular devices use a supported mobile data connection, and sometimes compatible Wi-Fi, to connect users through a configured service or platform. Coverage and operation depend on network availability, device compatibility and the service configuration.

Can PTT radios communicate with conventional VHF/UHF radios?

Not automatically. Interconnection may be possible with suitable gateway equipment and system configuration. Compatibility must be assessed for the specific devices and system.

Do all iTalk radios have the same features?

No. Features vary by model, hardware version, configuration and service. Check the individual product listing or our Kirisun iTalk FAQ for more information.
