Scanners allow you to tune into all UK local Mosque frequencies to hear adhan and listen to the Muezzin. UK Mosque’s operate on the UHF frequency spectrum at 400-480MHz normally around 440-450MHz. Many share the same frequency, but special licences are issued to Mosques for events and for wider coverage at certain parts of the year. Once you have purchased your scanner you just need to find the frequency for your mosque and save it the scanners memory.
