As a lot of people have pics of things unrelated to ham radio on their websites, I thought I would add a couple of my own (Scroll down for site updates). Banjo, our Red Heeler/Koolie cross at 4 months old. And at 12 months old (Feb 2016) enjoying his birthday breakfast treat of banana on toast.
New project added - my version of the X-Phase noise canceller. PCB available and a kit of parts to follow soon

Another addition to the Gallery section. This time, fitting a DDS module to a Philips PM5326 RF Generator to cure a bad drift problem.
26 November 2016
Additional software for the Simple DDS VFO added. This enables the pushbutton on the encoder to change step size (step sizes 10kHz, 1kHz and 10Hz). See the notes in the Download section of the Simple DDS VFO page for more info.

I have had some interesting conversations with homebrewers over the last few years relating to experiments/modifications of the works published on this website. One of the things on the 'list of things to do', was to publish some of their pics' etc on my website, so along that line, the first one, a filter/leveller for DDS modules from G3OAG, is now on my site. This one and all the others I have available to show, will be posted under the 'Gallery' menu. Now that things are starting to return to somewhat normal around here, I will endeavour to get the others up as quickly as possible (with apologies to those that have been waiting to see their work in lights).
Update 11 November 2012.
I have put up what most people would call, I guess, an end fed antenna. I prefer to call it a 22metre length of hook up wire at 5/6metres above ground level.
I have heard VK2's,3's,4's, 5's & 7's plus a ZL1 using it. WWV can be heard at 5MHz, 10MHz and 15MHz so it is working.
There are the constituant parts of a fan dipole sitting in a box waiting to be put up, but I need another support pole at the far end of the yard first. Currently, there are no HF antenna's in the air, or for that matter, any others. I am trying to decide between putting up just a long wire or a fan dipole for HF. Regardless, there will have to be another pole or other fixing point installed. There is a 12m tv antenna tower on the back corner of the house and, as part of the chook enclosure, I put up an ~6m pole on the back corner of the shed/shack. Between the two is not quite long enough for the dipole, so another pole will probably go in the far back corner of the yard. Left: Probably a little hard to see, but the tower in front is mine and Right: the ~6m pole as part of the chook run. If I decide to put up a long wire, it will be necessary to use an antenna matching unit. One of my purchases (at a very good price) a while ago was an ex-hams junk box. In it was the remains of an antenna matching unit, missing one variable cap which was later found at the bottom of another box. As you can see, there is a lot of cleaning to do before these can be put into service. Yes that is a roller inductor on the right. In the box was also a real valve/tube GDO. Don't know if it works yet. For VHF (2m), I have just completed a 3el Yagi, using materials kindly donated by a friend, in exchange for assembling an SDR receiver for him. It is made from 25mm aluminium square section and 10mm diameter tube for the elements. The day after completion, it was used handheld to receive Arrisat1 with one of those cheap Chinese handheld VHF units. Left: These are the un-assembled parts of the 3el Yagi. Right: Also included, this 6/2/70 mobile whip(Comet SB-15). Left: The assembled 3 element yagi and yes, the shadow is wonky because the element mounting is wonky (in my defense - I didn't drill the holes). Doesn't seem to affect the performance, but only proper testing would confirm it. Right: A close up of the gamma match, with weather proofing still to be done. The antenna design is by VK5JST, of "Antenna Analyser" fame, and can be found on his website - VK5JST web page
