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.

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. Banjo at 4 months And at 12 months old (Feb 2016) enjoying his birthday breakfast treat of banana on toast. Banjo at 4 months 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 it'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. Storm at 10 weeks

FT757 Battery Replacement

Replacing the battery in an FT757 in pictures

While hunting around the internet, I came across a document in French by Denis F4ANN about replacing the battery in an FT757 rig. Yaesu FT757 pic While maybe not homebrew strictly speaking, we are taking something apart, doing some soldering and putting it back together again (OK, technically it is 'repair work'). As I have an FT757 sitting on the shelf awaiting it's turn on the bench, I decided to translate it into English and put it into the 'information depository' for later. I also asked Denis's permission to put it on my website, which he agreed to. Rather than write it up as a web page, it is available to download as a pdf below. I figure others may want to store a copy locally rather than having to keep refering to a website they may forget where they saw it. One thing Denis did, was to replace the original battery:- Original FT757 battery with this type:- Replacement battery He also moved it to a more convenient location, should it ever need replacing again. This information may also be useful to anybody disassembling an FT757 for other repairs. Download the PDF file here: FT757 Battery Replacement
