Used my gift card from the holidays. Ordered the RDA5807M chip, a breakout board for it, and a TEA5767 board. I'll continue experimenting and writing code for the RDA5707SP while I wait the 2-6 weeks for delivery. Once they come in, I'll have all three of the I2C-controlled FM tuner chip sets (RDA5807x, TEA576x, and SI470x). Will eventually need to do a comparison of how well they work with the RPi, I guess. Also ordered a few other fun things to play with (more on those later).
Meanwhile... I'll be annoying the post lady and the UPS guy when I see them (back in Bart-Simpson-Lady-where's-my-spy-camera mode).
