There's small desktop loop,with a black plastic frame and copper magnet wire that shows up in the Amazon ads at the bottom of the page. When I bought mine it was made by Tecsun, but it's the same loop. It's a good performer and will hook up w/the enclosed cable to your portable's antenna jack. You tune it with a knob on the side.
For stations like that one in MO, it could make a big difference.
It's sold as the ETON NGAN 200 these day's, it was at the bottom of the page when I logged in. Same as the Tecsun I bought a decade ago. It's a good little mini loop.
