Amateur Radio for your PC and Smartphone
Easy to use Amateur Radio Software transceiver. Talk to Ham Radio operators all over the world. No extra hardware needed.
HamSphere® works in Windows, Mac, Linux, iOS and Android. Installation takes less than a minute. We offer a 30-day trial!
How HamSphere Works
HamSphere® is a virtual Amateur Radio Transceiver. Once installed, you will be able to communicate with thousands of Ham Radio operators and Radio Enthusiasts in over 300 DXCC entities around the world. You can even use HamSphere without a Ham Radio license by getting our special HamSphere call sign when you sign up.
HamSphere is a highly realistic shortwave simulation based on SDR (Software Defined Radio) technology. It is a modularized Amateur Radio Transceiver where operators build their own radio using plug-ins and virtual antennas. Once you download and install this software you will get a basic working transceiver for a trial period.
Expand your transceiver
Expand your HamSphere transceiver using a drag-and-drop system. Over 100 plug-ins and antennas available.
You can design many different transceivers for different purposes. No limits. Fun, educational and creative. Anything from a small footprint rig to a massive flagship. HamSphere also a wide variety of skins for your transceiver.
If you are into CW and morse code we have many CW plug-ins available. Take a further look in our Web Shop

Realistic HF Propagation
HamSphere is a unique platform, the only one of its kind in the world providing the experience of a realistic HF radio. For radio amateurs, the sun has a very special meaning. Because it is also the main cause for what can be achieved on shortwave and other bands, i.e. how well we can reach distant places by radio worldwide. We are talking about the propagation conditions.
The HamSphere propagation model takes in to account the physics of planet Earth, its surface topography like the continents, land masses, water bodies, oceans, lakes and seas. It also models hundreds of kilometers of atmosphere above the earth's surface, the ionization of gases in the upper atmosphere to realistically produce ionospheric layers.
The ionization due to the radiations from the sun based on Sunspot Numbers (SSN) and the Solar Flux Index (SFI) determine the behavior of the Ionosphere and follow the 11 year solar cycle.
When you start your HamSphere transceiver you will have the look, feel and sound of a real Amateur Radio transceiver.
HamSphere uses real modelled NEC designed antennas (Numerical Electromagnetic Code). We offer everything from wire-antennas, yagies and quads which adds to the total realism of the system. Rotatable antennas can be set between 0-359 degrees and the gain and characteristics of the antennas are very much like real HF antennas.
We provide antennas to cover all bands between 160-6m.
