How do you receive HF signals using your RTL SDR? You’ll probably say that the easiest way is to get an upconverter. That’ll certainly get you the best quality results. You might also suggest modding the hardware itself. This also works, but can be tricky if you’re not used to soldering.
There is a third way, however, and that is to hack the software so that the RTL-SDR dongle thinks the signal is bypassing the tuner on the dongle, as is what happens with the hardware modification. Continue reading
I haven’t posted here in about a year and a half, which is shameful! But, my last post was about low-cost SDR, and since then I’ve ventured into it. In this post I want to describe how to build a collinear antenna, which can be used for receiving ADS-B signals on 1090MHz from aircraft. I use a NooElec R820T tuner dongle on my laptop as my radio receiver (I’ll write up more about this later), and as I love quite close to an airport, it’s ideal for capturing signals from airlines.

Last night I saw a few mentions on a radio IRC channel of low-cost software-defined radio (SDR). Low-cost, as in €16 low, and not the €1,000+ it might usually cost. Immediately my interest was piqued. Continue reading
So my kit arrived yesterday. I had kinda wanted to jump straight in and get building but after a long day at work and a late night the evening before I just had to go to bed. But I’ve just finished building it!
Right. I expect my 30m kit to arrive any day now, and will hopefully get it built over the weekend. Now I just have to decide on my initial tests. Continue reading
Ordered my first QRSS transmitter kit today. Should arrive early next week, and hopefully I’ll be on the air soon after!
It’s a 30m kit from www.hanssummers.com/qrsskit.html
