If you want to get your feet wet with analog electronics, I'd suggest getting an Arduino starter kit, with a breadboard, some components, and a cheap Multimeter and Oscilloscope, and just start playing with things. You can fairly quickly build up an intuition of things if you've got something you can get your hands on. Once you get the hang of the basics at Audio and low RF frequencies, you can then set up GNU Radio, which works with your audio I/O of your computer, etc.. maybe add a $30 RTLsdr dongle, and the next thing you know, you've got a bit of RF under your belt.
