W/E 20-21st August 2016 – ILLW

We had a great weekend up at Barrenjoey, filled a few pages of the log book and ticked off a bunch of lighthouses. Richard NRA had some early success with his portable SOTA station while the rest of us battled high winds putting up the main station antennas. We got on air a bit late, but we were all […]

17-Aug-2016 Lecture – Can Home Solar Power and Ham Radio Coexist?

  The August 2016 lecture will be given by Graham Town.  We invited him to talk on renewable energy (mostly solar) and RFI issues this generation produces….  The idea for this talk came from the April QST article “Can Home Solar Power and Ham Radio Coexist?” More background at: https://web.science.mq.edu.au/directory/listing/person.htm?id=gtown Tweet

Book of Resistance

Book of Resistance

I got tired of wasting so much time looking for the right resistor in my resistor box.  I’ve got a good span of values, but not many of each.  I decided to buy a photo album and have 1 page per value, took me 2 hrs to organise but will save me so much, more […]

MWRS WebSDR Build – Part 3

websdr-internals

It’s been a while since the last update – sometimes life gets in the way of radio projects! The WebSDR node has been progressing though – we have all 5 Softrock kits assembled and installed, and the SDR node is functionally complete.  Unfortunately, my optimistic choice of a switchmode power supply turned out to cause spurious […]

DMM leads into the PSU

DMM leads into the PSU

When working on projects I often need to plug my DMM leads into my bench power supply to test PSU voltage, current drain, probe voltage onto the circuit, etc.  My PSUs have banana female plugs, I only use the spade side of the plugs, not the front holes.  I tend to poke the test leads […]

Flower Pot Antenna on a wire

Flower Pot Antenna on a wire

Here is a very handy aerial for permanent and field day installations. We’ve used VK2ZOI Half-Wave Flower Pot Antenna’s design, however we’ve only used the UPVC conduit for the choke section.  This gives us a 2m aerial on a wire.  It can be raised by pulling from the top, typically with a rope over a […]

Anderson on Jiffy boxes

Anderson on Jiffy boxes

Many projects require Anderson plugs to power circuits in jiffy boxes.  Here is a way to do it. The Anderson plugs have a flat side and a side with the hooks sticking out.  I faced the flat side onto the lid.  This will require that you either remove the lip on the edge of the lid, […]

CTCSS on Phillips FM92

CTCSS on Phillips FM92

In 1998 a large quantity of VHF FM92 radios hit the market at give away prices.  The MWRS had obtained enough to supply every member at the time, many took this opportunity, they were cheap and robust.  They were not small but most of them came with a remote head.  Many ended up as a […]
