At 10 years old, I was just like I am now, but smaller, a lot less comfortable with myself, and I didn’t have a cool hat. I was in the 5th grade, and there was a science fair coming up at school. I’d done somewhat well in the 3rd or 4th grade science fair, and …

The W7RLF BITX40: Finished at last!

Last year I thought the BITX40 was “done”. It successfully worked on 80, 40, 30, and 20m. It was truly multi-band! The trick to doing that was to make the Band Pass and Low Pass filters pluggable using QRP Labs filters. One only needed to open the radio, change the filters, and retune the VFO. …
