SRG SSR radio is currently broadcast in parallel via UKW & DAB+. This is more expensive and requires more resources than distributing the program in just one way. For these and other reasons, the aim is to switch completely to DAB+ in the future.
VHF vs DAB+
One of our employees is currently working as a project manager for SRG SSR on the expansion of Switzerland-wide DAB+ coverage. Nationwide transmitters ensure that we can receive radio, television and mobile communications. These transmission masts must be carefully operated and maintained in order to ensure trouble-free transmission of the signals.

VHF
VHF (very high frequency) is the analogue transmission of audio signals in a frequency range of 30 MHz to 300 MHz. Analog radio on VHF is only broadcast with frequency modulation, which is why the term FM is often used as a synonym for VHF radio.
DAB+
DAB+ (Digital Audio Broadcasting) is a digital radio technology that is mainly distributed over the air (terrestrial via transmitting antennas). In order to be able to receive DAB+ programmes, you need a DAB+ compatible device.
Benefits of DAB+
The main advantages of DAB+ over FM are
Diversity of channels (no more limitation of frequencies)

easier operation
Better and noise-free sound quality
Transmission of song information and info texts
And unlike internet radio, reception via a DAB+ device is free and anonymous.
