Dual Band BITX40 Project Update
I’ve written about putting together a dual band BITX40 in the past and the methods I used had varying success. The idea was to augment the built in filters with switched in/out add-on filters from QRP-Labs. This is a sound idea, but the layout of Low Pass Filter on the BITX40 really didn’t allow it …

Arduino is so easy that MisDotGeek gets a new header
I sat down at my desk tonight not sure what I was going to do. Right now I’m between QRP projects, as my uBITX hasn’t arrived yet and I’m not quite ready to put up my new antenna (I’ve got some building to do). So I grabbed an Arduino from my parts bin and a …

MultiBand BITX40 Conversion
MultiBand BITX40 Introduction In Several Older Posts I’ve touched on ways that you can make a multiband BITX40 radio. While those methods worked, they were experimental.

QRP Labs VFO Review [Spoiler: we love it!]
I’ve had the QRP Labs VFO for many many months now and it’s about time I got around to actually writing a review of it. When I originally purchased my BITX40, it did not come with a digital VFO. With the analog VFO, tuning was an exercise in futility. I had never owned an HF …
