https://www.rigpix.com/jrc/jrc_nrd515.htm

Robustly built and straight-forward to operate, this receiver remains popular with utility DXers, tropical band enthusiast and general shortwave listeners. The '515' has a nearly cult-like following. It was the first JRC priced to enter the consumer market and enjoyed wide popularity. Matches the NSD-515 transmitter. The BC Tune function (on the BFO knob) serves as a manual preselector on the MW band. Requires a speaker. The optional external memory units store only frequency. Clean lines, easy operation, a solid feel and outstanding performance come together in this radio. Excellent for radioteletype, fax and Morse code
