Planned Transmission Timetable
We will be using the Amateur 20 Metre, 40 Metre and 80 Metre bands for the transmissions.
- The 20 Metre band lies between 14.000 MHz and 14.350 MHz
- The 40 Metre band lies between 7.000 MHz and 7.200 MHz
- The 80 Metre band lies between 3.500 MHz and 3.800 MHz
Each of these bands is split into sections with preferred operating modes. It is impractical to define exactly what frequency within each band will be used during the Cipher Challenge - the spot frequencies in the table below have proven workable during early testing.
