Frequently Asked Questions
James E Smith LLC provides customizable two-way radio communications software for researchers, expedition teams, and independent field teams. These answers cover what the software does, how it works with your equipment, and how to order.
What is the software?
It's customizable two-way radio communications software built on a software-defined radio (SDR) platform. It supports analog AM and FM voice, push-to-talk operation, and digital voice, text messaging, and live image transmission. We sell software only. We do not manufacture handheld radios or SDR hardware.
Is this a walkie-talkie app?
It works like a walkie-talkie system, but it is professional radio software, not a phone app. It runs on a Linux computer or single-board computer that you own and connects to compatible SDR hardware. It can also work with the handheld radios, repeaters, and base stations you already use.
Does it support push-to-talk?
Yes. Push-to-talk is a standard feature. Operators transmit when they choose to, as on a conventional two-way radio. We can adapt the controls, such as simplified field layouts, to how your team works.
Which frequency bands does it support, including VHF and UHF?
We configure bands for each customer. Tell us which bands you need, including VHF, UHF, or others, and we tailor the software to them. Your SDR hardware sets the usable range, so we confirm compatibility before you order. Operators can control center frequency, receiver gain, transmitter gain, and tuning.
Does it support both analog and digital communication?
Yes. Analog AM and FM voice are supported for compatibility with conventional radios. Digital voice, text messaging, and live image transmission use digital transmission methods and are separate from the analog modes.
How does encryption work?
Encryption is optional and uses peer-to-peer key exchange. The devices exchange keys directly, and the keys stay on those devices. Nothing is sent to a server. Encryption rules differ by country and by radio band, so customers should check what is allowed where they operate.
Do I need an internet connection, cloud account, or subscription?
No. The software runs entirely on your own equipment, with no cloud dependency and no mandatory subscription.
Can it work as a mesh radio network?
Mesh relay and data forwarding are available as custom builds. Tell us about your range, number of nodes, and terrain, and we will scope the work with you before you order.
Do you offer repeater software?
Yes, as an optional add-on. You can use the platform with our repeater software.
Will it work with my hardware?
Probably, but expect some customization. Radio hardware varies a lot, so we usually adapt the software to your setup. Send us the details of your SDR, handheld radios, and computer, and we will confirm compatibility before you commit.
What can be customized?
Most of the workflow. Examples include research data formats, preset channel plans, simplified field controls, operational logging, and integration with existing equipment. The plugin-based design lets us add features without changing the core system. We agree on the customization with you before your order is finalized.
Who is this software for?
It is designed for researchers, expedition teams, and independent field teams that need dependable two-way radio communication with control over their own equipment and data.
Is it legal to use?
That depends on where you operate and which bands you use. Radio regulations and licensing differ by country. Customers are responsible for following local rules on frequencies, transmit power, and encryption.
