The transmitter comprises a 108.010MHz ovened xtal oscillator F2 modulated. The frequency is locked using the reverse DDS technique to a GPS referenced 10MHz source.
The output of the 108.010MHz source is fed to a mast mounted box containing a frequency multiplier and amplifier producing a filtered output at 10368.955MHz of 1.0Watts.
The antenna is a waveguide slotted on both sides thus producing an approximately omni radiation pattern with a peak erp of 10dBW.
