This year, my place of employment gave me an end of year bonus, and it was substantial. It was, in fact, the largest bonus I have ever received. So, I went a little nuts buying stuff, mostly electronics. I got a couple of things I've wanted to get for a while. An SDR receiver dongle that works for HF, and a device I've wanted to buy for a while, which is a HackRF One. A HackRF One is a software-defined transceiver that covers all the frequencies from 1 MHz (and possibly lower) up to 6000 MHz.
Well, after thinking about it, and using all the tools at my disposal, including colorful language, I managed to get the old S8050 out of the S-Pixie kit. Now, I've been buying component assortments for years. I figure that if I want to build my own equipment, especially equipment of my own design, I'll need parts and it's better to buy cheap assortments well in advance than to order the specific parts that I think I want. I mean, the fact that I have, say, an S8050 transistor, that can guide my designs to use parts that I have rather than be overwhelmed by all the parts that there are.
