News, Updates and Other Minutiae

I have, for quite a while, provided modified versions of the code for my projects free of charge. However, the cost of webhosting for this site has tripled in the last couple of years and the little I make out of the pcbs I sell goes nowhere near covering this cost.

As of October 2017, I will be asking for a donation in exchange for providing custom modified code for my projects to help keep this site available.

November 2017

A modification plus software to allow the Simple DDS VFO to be re-calibrated as often as you want without having to re-program the PIC has been added to the Simple DDS VFO page. Simple DDS VFO bug problem fixed. Code uploaded to webpage as version 'c'.

October 2017

There is a bug in the Simple DDS VFO code. See Simple DDS VFO page for the problem and updated code. Included an add-on for the Simple VFO project to indicate which step size has been selected. Simple DDS VFO project updated and software file uploaded. The pushbutton on the encoder is used to change step size (step sizes 10Hz, 1kHz and 10kHz).

September 2017

Noise Canceller kits now available.

July 2017

Updated both the DDS Xtal Substitute and DDS Xtal Substitute Mark 2 projects into one project. The original webpages are available to download as PDF's.

May 2017

New project added - my version of the X-Phase noise canceller. PCB available and a kit of parts to follow soon


Welcome to my little corner of the Internet known as VK5TM. Hopefully, it will turn into something useful to somebody at some stage. My name is Terry (Ham callsign VK5TM) and I live with my wife in the small town of Tintinara in South Australia. It is intended to put my endeavors in getting back on the air, as well as homebrew (constructional) projects on this website. Current ham equipment consists of an FT7 donated by a friend, an FT757Mk1 (Purchased cheap with a known receive fault), two Jing Tong handhelds (2m and 70cm) and assorted accessories either purchased cheap, donated by friends or home built. An old and eclectic array of equipment yes, but a bad car accident some years ago leaves no choice but to make do with what one can and hopefully it will inspire others to get on the air as well. Other hobbies include electronics and model railways. It is electronics that basically ties all my hobbies together in one way or another and was also the major part of my working life. As this website progresses, I will add a seperate area for the model railway stuff and the electronics will be encompassed by the homebrew section of the site. I'm slowly getting to grips with HTML5 and CSS (and PHP as of July 2012) so the site is progressing. Update notes will be put in the left column under the menu as things change. Rather than a long list of dates only a couple of dates will be left there. Older dates will be dropped off. This site is being written with Notepad++ rather than an all singing, all dancing web package. Unless absolutely necessary, there wont be any flashy whirly-gigs, fancy what-sits or scripting of any sort on this site. Some may say it looks 'so last year', but I was born well before last year and that's the way it's going to be. You should have noticed by now that there are no ad's or pop-ups on this site. This site is paid for out of my own pocket, so I may ask for donations at a later date. As much as I would like to, I'm not going to put any time frames on the updating/addition of new material to the site, but I will do my best to try and add something extra on a monthly basis at least. The menu to the left will hold the major area pointers and each area will have their own sub menus. With the change to a mobile friendly site, the menu bar is now across the top, so any references to the 'menu on the left' should be interpreted as 'the menu at the top'. Any off-site links will be at the bottom of a page and will open in a new window.
