I've been playing with a SDR (Software Defined Radio) for a couple weeks now. I bought an SDRPlay RSP Pro, a Wonder-Wand HF tuner/antenna, an MFJ-9232 loop antenna tunner, and lots of other odds and ends.
Turns out that like most other radios, the antenna is the most imporant part, epspecially on HF. I've experimented with a couple, and so far a loop conected to either the Wonder-Wand or MFJ-9232 has worked best. So, I decided I wanted something portable, easy to take on the road and set up anywhere.
I built this. It kind of portable, in that it only takes me about 15 minutes to tear it down or set it up, and I it will find in the back seat of hte car when in pieces.
