The transmitter, built by Bernie G4HJW, comprises an OCXO which is frequency modulated with callsign and locator using morse code.
The OCXO output is frequency multiplied and filtered then amplified to produce a transmitter output on 432.490MHz of 10dBW.
The antennas are two 5 element yagis, maximum radiation directions at 135 and 300deg. Power from the transmitter is shared equally between the two antennas.
Returned to service May 2020.
