As part of a booth organiser for the Amateur Radio & Electronics booth this year we are planning to be more hands on and are going to have a remote station that we’ll have access to in country Victoria we can us to access and transmit on the 40m band via the internet, which we’ll allow the public to make contact with other stations to get a first hand fell to what one aspect of amateur radio is about.
Also hoping to have some IRLP action going to via the VK5RAD 70cm repeater.
If your interested in testing the at accuracy of you your transceiver on 6/2/70/23/SHF there are beacons setup in around Mt Lofty (VK5VF) and the Elizabeth Water Tower (VK5RLZ) which you can listen to and they are on the following frequencies
Well this is the conclusion after having bit of a play and a fiddle with this 3 element Yagi that I built based on VK5JST build notes. For a 3 element Yagi it is rather directional of about 45 degrees, and very deaf at the back which is a good thing for some setups. Overall it is a rather unusual design with characteristics of much larger Yagi’s for the same band. I have been able to get 1.2/1.3-1 SWR on my Yagi for 146Mhz which I am rather chuffed with and had a good QSO into the VK5RHO repeater from my place. I could probably get better SWR if had a network analyzer to see exactly what the Yagi is doing over 144-148Mhz 2M amateur band.
This Yagi was well worth the time it took to build.
Well today I made the gamma section for my Yagi and mounted it and also added rubber bits for the ends of the elements and end caps for the boom. I have done a quick test of the Yagi with a 10pF capacitor and the SWR is ~1.5-1. I got a couple air variable capacitors I going to put on the Yagi to better tune it. As it was a lovely day most my work was done outside on the deck.
Tonight this is the bracket I made for the SO238 socket all riveted and mounted to the boom of the Yagi. All that is left to do is make the bracket to hold the gamma matching and to fine tune the Yagi, all going well I should have it finished during the week
This is a 3 element 2 meter band Yagi design by VK5JST that I am giving ago to make. The only difference is I am using 12mm OD round and 19mm OD square aluminum (as it what had around from another project) and I have used 3.2mm dia x 4.5mm long aluminum rivets to hold the elements to the the boom. All I have left to make is the bracket to hold the gamma rod and the bracket for the connector and drilling the holes for the v/u bolt assembly.
The pictures below are where have got thus far.
and yes that is the kitchen table I am working on, ssh don’t tell anyone. hehe
I bought one of theses Wouxun dual band HT off of eBay a month back for bit over 100USD which amounted to around 99AUD. The unit didn’t come with any extras like 1700mA battery or USB programming cable as sold by others on eBay.
Down side is the HT is pita to program off of the keypad till you get used to it, altering power setting etc to a channel already saved is a pain as you have to delete the channel and re enter it. I ended up buying a USB programming cable off of eBay for the HT and it makes the programming of the HT a lot easier and faster. The other is the SMA Female antenna connection, as if you want to use a external antenna you have to make or buy SMA female to BNC female adapter, which are also sold on eBay for couple dollars each.
As I use Linux, I have been lucky as there is a Linux program called OWX, which is a command-line program for programming the KG-UVD1P and others. As I didn’t do the make install part of the compile/install of the OWX program, here is an example of how I use the program to do what is explained in the OWX documentation.
Overall the Wouxun KG-UVD1P is a rather good and not bad for the monies, feels sturdy and comfortable to use, it be a good starting out HT for beginners to Amateur Radio. I would also recommend if getting this HT to get it with the USB cable and the 1700mA battery.
