Several useful tools. 1) Tecsun PL380 -- a nice AM/FM/Shortwave portable, DSP IF, has built-in loopstick antenna. About $45. 2) A ham talkie that has wideband RX. My Kenwood TH-F6A does that and has
I bought a surplus LORAN square loop years ago. Designed for 100 kHz, it was easily converted to 1.83 MHz with a single capacitor. I mounted it to an old car's roof using ski racks and 2x4's and it h
