Laurie ZL2TC briefly went over some of NARC’s previous efforts and outcomes.

The club project: Suggested were 1) a horizontally polarized (halo) 2m/70cm aerial, 2) a simple radio / computer interface for digital modes, 3) a dummy load with or without power meter, 4) an active receive only antenna.

After some discussion the dummy load won. Dave 2MQ to do some research and report back.

Laurie 2TC reported that the Wanganui ARS (Branch 48) is installing a broadband aerial, SDR receiver and associated gear to provide an online service similar to the Northland one. To go live early 2020.

The meeting closed at 8:10 pm

And was followed by Errol ZL2IT’s presentation of part two of the 475 KHz story: Transmitters “class E design,build and test”, antenna tuner requirements and antennas for 475 kHz.

Errol’s investigation and experimentation resulted in a ‘home-brew’ functional 630m transmitter and antenna putting out 15 Watts. The single transistor class E amplifier is switched on and off by a square wave output oscillator. Close to a sine wave is produced through filtering. Errol used WSPR mode for contacts made so-far, some with VK land. Class E transmitters can be used for CW, AM, FM and most digital modes. Antenna construction: a base loaded vertical with bucket sized adjustable coil.

Errol ended his excellent slideshow presentation with an invitation to all interested in 475 KHz experimentation to visit his QTH for a chat and a cup of tea.
