News, Updates and Other Minutiae

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

Old QSLCards

A long time ago, I was doing a job for a customer who was about to move house. In a pile of stuff destined for the rubbish were some very old QSL cards, which I was told I could have if I wanted them. Below are some low resolution scans of some, along with a hand wriiten letter (remember those?), that date from 1913 to 1925. I have about 90 of them, most dating around the same period. I will post some more as time (and inclination) permits. Most are in reasonable condition, but at least one is in very poor condition. Note the schematic drawing on the back of the letter.
