[Premium-Rx] Longwave Receiver Recommendations?

[Les Layton]

I also have a CEI-357, purchased years ago from Fair Radio Sales. Does a very fine job on VLF with just a end-fed 15 foot vertical antenna up about 20 ft. off the ground. Works best with an external 500 kHz low pass filter in line to keep the local broadcast stations from overloading the front end. Also have a WW2 vintage National RBL-5 which tunes 15-600 kHz in 6 bands. There are still many NDB (non directional beacon) stations in operation throughout the world (between 190-535 kHZ in North America) . I have logged several hundred over the years. The best place to go for identifying  NDB signals is:
