The ZL1SIX Ocean Floater project:

An ocean going marine buoy containing a GPS and Ultimate3S based transmitter. This project is intended to drifted in the Pacific Ocean at the mercy of the tides, currents and wind directions while sending its position, battery voltage and temperature information via HF radio telemetry on the 30m band in WSPR and JT9 digital modes. The battery bank finally went flat on 29 June 2017 after 407 days at sea.



WSPR tests:

Experimenting with various antennas on RX and sometimes also transmitting with a QRP-Labs Ultimate3S (U3S) transmitter. The kitsets from QRP-Labs are very well done and a LOT of fun to experiment with.



Six Meter Band Beacons and 'Indicators':

All the significant VK and ZL low band TV transmitters (6m propagation indicators) closed down during 2012/13

The following 6m Beacons are currently operational from ZL:

ZL1SIX ... 50.0110, 25W ERP from RF64VT

ZL1VHF ... 50.0433, 20W ERP from RF73MB, attended beacon while a permanent site is being arranged

ZL2WHO/b ... 50.0240, 800W ERP from RF70OM

ZL3SIX ... 50.0399, 100W ERP from RE66EJ

ZL3MHB ... 50.055, 20W ERP from RE57MI
