rangeĠ.5 - 3 kHz where nearly all natural emissions occur which are readily audible to human ears easily. RFI protected via input RC filter to reduce/eliminate LF-VHF broadcast, Loran-C radio nav., and utility station overload and IMD.Īudio Output: Maximum 100 mW into 16-Ohm stereo headphones. 1.5 to 3 kHz with gradual frequency roll-offs below 200 Hz and above 4 kHz to slightly-reduce 50 and 60 Hz hum and also excessive Russian ALPHA Radionavigation signal reception (Alpha begins at about 11 kHz). The WR-3 is only available direct from S. The WR-3's headphone jack is compatible with line-in inputs - I directly connect my own WR-3s to my Sony Mini-Disc recorder's line-in jack via a 3-conductor mini-plug (1/8 inch/3.5 mm) stereo patchcord, and monitor the audio using the mini-disc recorder's headphone jack. The WR-3 remains very popular and in use worldwide.

This hand-held receiver is a great unit for taking along wherever you may go - slip it into your pocket! Very easy to use, the WR-3 has one control knob, antenna jack (BNC type) and headphone jack (1/8-inch mini-stereo type).

VLF RECEIVER PORTABLE SERIES
(408 La Cresta Heights Rd, El Cajon, CA 92021, USA: This great antenna is 10 section, 54-inches/138 cm in length fully extended, with a loading coil on its base for use with ham radio 2-meter hand-held radios or scanners, and it works great with the WR-3 as well, because the matching-coil is in series with the antenna (and not shunted)! You can also order more from their great website at Smiley Antenna, Inc.Ģ) At: ALF Enterprises, 18933 59th Ave NE, Suite 114, Arlington, VA 98223, (360) 403-4840, Order the BNC-based whip antenna at ALF Enterprises HERE.Īnother good antenna, albeit a bit shorter that the Smiley SS-II antenna is the Tandy/Radio Shack scanner antenna - the loading coil does not affect VLF reception in either antennas as it is in series, not parallel shunted. Many people might have their own whip antennas, but we recommend the Smiley Superstick II telescoping-whip about 1.3 meters in length (54-inches fully extended).Īgain, the very popular telescoping antenna (included) works excellently with the WR-3 is the "Super-Stick II" 2-meter 5/8-wave made by Smiley Antenna Co., Inc. When camping in my camper-van, I use a similar unit modified for in-vehicle use (The WR-4b) that has the same sensitive input circuitry and identical audio amplifier.Īll WR-3's have BNC antenna connectors (Amphenol female-bulkhead-receptacle type) on their topsides for use with telescoping whip antennas that have a male BNC connector mounted on their base. When I must bicycle or walk into listening sites or simply to check out a potential listening site for extended recording sessions, I use a WR-3 hand-held unit to make my observations and to check for powerline hum levels and site suitablity conditions. The unit is highly portable, and I use a a few of my own collection during my VLF recording expeditions. The WR-3 is a self-contained, hand-holdable unit. All are listenable with the WR-3 presently and depending upon daily/nightly conditions.Ī montage of my own large collection of various WR-3s and prototypes and a shot of me in the eastern Mojave Desert listening to sunrise whistlers. I like listening to the beautiful sounds of night-time lightning static "tweeks" which I find beautiful and musical. Equinoctal periods (April/October) often also offer the best months of whistler and potential chorus reception. There are about 1 to 3 days of good whistler-listening mornings and about midnight period Winter 2017-2018. Here is information about the WR-3, a compact, fully hand-held and self-contained ELF-VLF receiver I manufacture and sell which allow you to do your own listening and observing of natural ELF-VLF radio phenomena signals for the start (and now solar-minumum period) of Solar-Cycle 25. Older WR-3 with shiny aluminum enclosure and the Super Stick II whip antenna Discover the World of Natural Radio Below 10 kHz! Musicians, Field-recordists, ELF-VLF-hobbyists, ham radio folks, and an amazing variety of people who are exploring new radio/audio realms are listening to natural radio and using the sounds in their own musical works.

Each new WR-3 receiver comes with the Smiley Antenna Superstick II antenna.
