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).

Additional software for the Simple DDS VFO added. This enables the pushbutton on the encoder to change step size (step sizes 10kHz, 1kHz and 10Hz). See the notes in the Download section of the Simple DDS VFO page for more info.

20 November 2016

I have had some interesting conversations with homebrewers over the last few years relating to experiments/modifications of the works published on this website. One of the things on the 'list of things to do', was to publish some of their pics' etc on my website, so along that line, the first one, a filter/leveller for DDS modules from G3OAG, is now on my site. This one and all the others I have available to show, will be posted under the 'Gallery' menu. Now that things are starting to return to somewhat normal around here, I will endeavour to get the others up as quickly as possible (with apologies to those that have been waiting to see their work in lights).

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.
