Amateur Radio ‘Radio Foxtrot 100′ Radio Station

There’s a new radio station on the web, and this one is aimed at amateur radio enthusiasts and is to be on-the-air 24 hours a day, seven days a week, with a mixture of music, chat and ham radio items.

Radio Foxtrot 100

Linux users at the moment by looks of it have to copy and paste this link into there favorite media player ie VLC in my case

this is due to the problem I have found with the broadcast page play and is not Linux friendly because the following code which seems to be all Windows Media Player based:

Dual Band (2 Meter & 70 cm) Solid Aluminium J-Pole

This is what I have been up to for the last week or so, building this dual band antenna out of solid aluminum, I have used 10mm solid aluminum rod, and 40mm x 40mm x 3mm angle strut for the base and the driven element connected via SO239 3/8″ stud mount.

I am very happy with the performance of the antenna and the SWR of it. and it was a hell of a lot cheaper than buying one, and more fun :-P

And if you are interested in me making one for you, head on over to my contact page and send me a message

Wouxun KG-UVD1P Dual Band HT

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.

./owx -c check -p /dev/ttyUSB0
./owx -c get -p /dev/ttyUSB0 -o radio/original.bin
cp radio/original.bin radio/backup.bin
./owx -c export -i radio/original.bin -o vk5-repeater-list.csv
cp radio/original.bin radio/vk5-repeater-list.bin
./owx -c import -i radio/vk5-repeater-list.csv -o radio/vk5-repeater-list.bin
./owx -c put -p /dev/ttyUSB0 -i radio/vk5-repeater-list.bin -r radio/backup.bin

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.
