In the United States, statistically, the 'northern tier states' region is blessed with the highest number of whistlers and chorus occurrences (Washington State, northern Idaho, Montana, North Dakota, Minnesota, Wisconsin, Michigan, Pennsylvania, New York, and New England. The latitudinal zone where the loudest whistlers are heard falls roughly between 30-55 degrees north for North American listeners. Whistlers of intense strength can sometimes be heard across the middle and southern-most United States and southern Europe and North Africa. from eBay listing): The WR-3 requires at least a 1 to 2 meter long (39 inches) telescoping whip that has a very-commonly-available MALE-BNC base connector (36 to 66 inches) for excellent sensitivity) and quality 8 or 16-ohm headphones with a 3.5 mm / 1/8-inch mini-stereo plug (very common), and you're good to go! It will not work with a loop antenna because a loop is very low-impedance - it operates strictly and optimally with a 1-meter long or longer (40 inches-plus) telescoping whip or vertical wire antenna/aerial (use no coax or only a short 2) and can take on incredibly beautiful sounds. Regarding the Diamond Rh205, it is best to obtain the shiny chrome-plated (metal) version rather than the cheaper black 'Japanese knock-off' version. Also, the excellent Diamond RH205 VHF/2-meter 5/8 wave antenns is also great and very similar to the Super Stick II. Any of the four available from Smiley Antenna are great. Examples of excellent telescoping-whip antennas to use with the WR-3 is the Smiley Antenna 'Super Stick II' for 2-meter and/or the aero-band. The optimal length of the whip-antenna should be between 1 meter (!39 inches) to 2 meters (~78 inches) in length. ANTENNA: It requires and functions optimally with a vertical-antenna (telescoping-whip type with a base BNC-mount/connector) to receive VLF signals and requires stereo-mini headphones to be plugged into its output for listening. Welcome to the realm of extreme and very-low-frequency (ELF/VLF) 'Natural Radio!' The WR-3 is an electric-field ('E-field') type of 'whistler receiver' specifically designed to monitor naturally-occurring VLF radio emissions of Earth that occur in the 300-11,000 cycles-per-second (0.3-11 kHz) audio-frequency ELF/VLF radio spectrum.

One or two series 47 K resistors(s) plus a parallel termination-resistor of 1K suffices fine for interfacing the WR-3 joint 3.5mm audio-output jack (headphone level audio) of the WR-3 to the mic-level input of PCs and phones so you may employ their recording apps! (Stephen P. the lowest conductor closest to the 'holder' of the plug (3.5 mm type/4-conductor) is the mic-level connection).

about how to interface the WR-3 output jack to the newer PC/phone 4-conductor jacks that combine stereo audio outputs with a monoural mic-level input (i.e. Information for recording using Sony Mini-Disc (MD) recorders and memory-chip-recorders (like my Zoom H2 employing an SD-card) has been added to the Recording section. This WR-3 Receiver booklet/guide is also highly useful for all Natural Radio listeners due to its interesting information pertaining to Natural VLF Radio that I have been compiling since 1991. This WR-3 Listening Guide was first begun in mid-1991 and updated as of THE POCKET-PORTABLE WR-3 NATURAL-VLF-RADIO PHENOMENA RECEIVER
