VHF & UHF bands
This is an interesting part of the radio spectrum, where both ionospheric and tropospheric propagation occurs at the lower VHF bands to entirely tropospheric propagation on the higher band. In addition other propagating mechanisms are practised such as meteor scatter and moon bounce.
The VHF/UHF bands are also home to a wide range of systems, including repeaters, gateways and satellites. Innovative digital developments are also key to our ability to access new spectrum at 71 and 147 MHz (See VHF Spectrum Release) .
For more about operating on these bands, please see the following pages:

Technical consideration of these propagation modes are discussed in more detail under Technical Topics.
If you have any suggestions regarding any of these bands the please contact the VHF Manager.
