News, Updates and Other Minutiae
November 2024 Phillipe F6ETI has done some serious testing on the Noise Canceller and shown it works up to 72MHz and is usable with some loss at 145MHz. Links to his website with photo's, video's and description of the testing on the Noise Canceller page.
September 2023 Long time between drinks, but not much happening on the tech front at the moment. Added another couple of rants to the rant page.
January 2023 Updated the AD9833 VFO code to use a 12F1840.
December 2022 Added rant about todays useless (internet) search engines.
November 2022 NEW Project An AD9833 Based Simple VFO. FT101ZD VFO project updated.
October 2022 A replacement internal DDS VFO for FT101Z/ZD rigs. Because the worlds postage system has gone totally bonkers and it is not possible to send a small pcb anywhere except at extreme cost, I am slowly making available the option to purchase pcb's from Pcbway. First up is the Simple DDS VFO 2017 project pcb. Others will be added over time. Noise Canceller kits available again- see Noise Canceller page.
Privacy Policy uploaded. GPDR and all that stuff In accordance with various bits of legislation around the world, either currently in force, about to come into force or proposed, you will now find that annoying "We use cookies" notice at the top of this website. The full Privacy Policy is available at the Privacy Policy link in the footer at the bottom of the page. (If you don't know what GPDR is, Google it. Real scary shit for ANYBODY with a web presence.)
Welcome to the website of VK5TM.
Regular visitors to my website know what is available here, but if you are new to my website here us a quick run-down of whats here. Some information and software (PIC based) on the use of the AD9850/51 modules that (were) cheaply available from various auction sites. Projects range from a signal generator to a simple VFO and even a Xtal substitute. A project using the Si5351 as a Xtal substitute, originally for the Pic-a-Star project (search the internet for it), but useful for other things as well. In todays world of never-ending interference, there is the Noise Canceller project. This is my version of the X-phase project and while not a solution to every interference problem, it does help in the majority of cases. There are a few videos on the net showing this project in operation from various builders, just search for VK5TM Noise Canceller. Also, there are some Model Railway projects (I haven't worked out why there is a reasonably large proportion of Hams who are also into trains/model railways, but there are). These pages are still in the "Under construction" phase with some basic information available. They will slowly be completed as time and inclination allows. There is more tucked away on the various pages which can be accessed from the menu bar at the top of the page. See the left hand side for updates/changes/whats new etc.
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. 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.
A new addition to the family, an 11 week old kitten (end July 2017), rescued by Banjo after being trapped between a water tank and fence. Her name is Storm after her colouring and she's eating a bit of toast and jam (yes, our animals do eat strange things, including lemon meringue pie). They are now the best of friends.
Banjo hasn't got any bigger than he was at 12 months old and although Storm has, she is going to be a miniature cat. When I can get her to sit still long enough, I will try and get a pic with some sort of reference to show how small she is compared to other cats of the same age (she weighed 2.5kg when we took her to the vet to be spayed mid Nov 2017). In the meantime, above is a pic of the pair of them together under the ceiling fan (it was a stinking hot day).
Banjo in his favourite spot in 2021 - the ultimate couch potato.
RIP OFF MERCHANTS!!!!
These people have dishonestly STOLEN my hard work for their own benefit. Bukalapak - YC9FY https://www.bukalapak.com/p/elektronik/walkie-talkie/lshqpu-jual-pcb-dds-vfo-vk5tm-fr4 <-this is not a clickable link. Far Circuits USA - recent information (November 2018) indicates this prick is still at it, despite a Cease and Desist Notice. There are probably others I am not currently aware of, but as I find them, they will be added to this list. As a result, I will no longer make available pcb design files for any of my works. THERE IS NOBODY SELLING ANY OF MY DESIGNS THAT HAS MY PERMISSION.
