Tony Canning G2NF has an intriguing evening lined up for us next meeting:
Thursday 12th October, Woodford Park Leisure Centre, Woodley, 8pm
Some of you will remember his superb talk on ‘Tricks with Coax’.
He states:
“Given my interest in coax related stuff and various tricks, I have been
playing with an audio filter that can give the user with no IF 200Hz
filter a similar tool in a pile up, and like wise for the SSB operator
an audio notch filter. There is no eltrickery, smoke mirrors or power
supply involved. I think its a great resonance demo, as the relationship to coax filters and tuned circuits is uncanny.
Can be made from house hold items or from Wickes / Screwfix or BnQ etc.
This is not about Audio DSP but my simple efforts do appear to offer
comparable performance to some at a fraction of the price but much more fun building and learning.”
Continuing the theme of sharp resonance, I’m trying to twist G2DD’s arm (Loz) into bring along the coax based magnetic loop antenna he’s been working on as I know a few people would be interested in having a go at making something. Or indeed – if you have been working on one feel free to bring it along and tell us what you’ve been up to!
Refreshments to be served as usual with an increasingly wide selection of biscuits of variable age.
