NDB hunting can be enjoyable. I haven't done it in a year or so, been too busy.
If you are not proficient at Morse code, it takes a little bit of extra work to figure out what you are listening to, but you can pick it up pretty quick.
I used to map out the beacons I was hearing. From my location on the west coast, I'd pick up beacons from Hawaii, and all up and down the west coast.
I've got a couple of different radios I use,
I've got an old RDF set like in the video. Works OK, not a very selective receiver, but the analog tuning can be useful for finding them. The big ferrite antenna can work well.
I've got a remote receiver at work that happens to cover down to 40KHz, and it's connected to an end fed wire. Works pretty well.
I've got an old Sangean 803 that covers down to 150KHz, works well.
A couple of years back, I picked up a used Rycom frequency selective voltmeter that will cover from 0 to about 3.5MHz. I built a 3 foot square loop antenna. I've played with it a bit, but my ideal goal is to get it out into some remote areas away from power lines and manmade noise.
