For quite a while now, I’ve been thinking about what I should do about software-defined radio (SDR). For one thing, I’d like to write about it here on KB6NU.Com. For another, I’d like to learn more about it – how it works, what’s available, etc.
I”ve decided that short of writing a book about the topic, I’m not going to try to write something comprehensive, but instead just little bits about SDR as I come across them. So, with that in mind, here’s some SDR stuff that I’ve come across recently.
- DVB-T Mini Digital TV USB Stick Dongle. Based on an exchange of e-mails on the AMRAD mailing list, I recently purchased one of these little dongles. Apparently, a bunch of AMRAD members purchased this unit at a recent hamfest, and they’ve all been having fun with them. The one I bought covers 48.25-863.25 MHz and only cost $12.40, shipping included, from Hong Kong. I’m anxiously awaiting its delivery.
Coincidentally, one of the guys here in Ann Arbor, purchased a FunCube Pro dongle at Dayton and brought it down to the museum Saturday. It costs significantly more ($150), but it will tune 150 kHz to 1.9 GHz. It will be fun to compare the two.
- SoftRock, Peaberry. A couple of months ago, I purchased a SoftRock Lite II kit from someone who hadn’t gotten around to building it and decided that he was probably never going to get around to it. Well, of course, I haven’t gotten around to building it yet, either, but I do hope to get to it sooner rather than later.
I have since come across the Peaberry line of kits. The Peaberry SDR V2 kit looks interesting. For $150, you get a multi-band SDR transceiver.
- RTL-SDR.Com. This blog covers a wide range of topics including how to receive all kinds of different transmissions with DVB-T dongles that use the RTL chips. One recent article compares SDR using the RTL dongles and the FunCube Pro dongle.
