July 2014 Meeting - A Look at AIS

This months meeting will be A Look at AIS (Automatic Identification System)

The Group has installed an AIS receiver at Colonial Knob and this is providing a large coverage over the busy Cook Straight region.

This month we will look at where AIS came from, its purpose in marine safety, what the latest directions and trends are, and what the future may hold.

An interesting aside in the use of AIS for VHF propagation studies by amateurs, and what is being done in this area in New Zealand

Date: Thursday 31 July Time: 7:30 pm
Location: Tawa Community Centre

Marine AIS Receiver Operational

The marine AIS (Automatic Identification System) is an automatic tracking technology used by ships to send and receive position reports. Vessels send positions derived by GPS to inform others and optionally receive positions from other vessels for local display.

A useful AIS overview is here:

APRIL 2014 Meeting - ZL4JY - A new digital age - TRBO and P.25 - carried over from February

John has recently joined his MotoTurbo repeater as a node on the worldwide MotoTrbo network. This enables easy communications to nodes around the world using pre-set talk groups. MotoTrbo and P.25 continue the amateur tradition of converting commercial gear to amateur use in a way that takes it beyond the original use. There is also gear from amateur suppliers and plenty of used gear on Ebay and TradeMe. This is quite an exceptional direction for digital comms and an exciting direction for the amateur world.

Digital Television tests - Bulletin No 10

Members of the DATV Project Team recently met with representatives of several Government agencies to
discuss the final series of adjacent-channel spectrum compatibility tests.

Following the extensive series of field tests that have been carried out, and laboratory simulations using an output filter
consisting of a 6-pole cross-coupled bandpass filter plus a 6-notch filter, we expect a successful
outcome from the tests.

We are grateful to one of our corporate sponsors for the bandpass filter, and also to our member Steve ZL2ASF,
for the notch filter.
