US$125.00 if you would like a 49-inch/136cm, 10-section 'Super-Stick II' telescoping-whip antenna with BNC-base included. A BNC-base telescoping-whip antenna is extra). US$100.00 for the WR-3 and CD containing 60 minute of audio (entitled 'Auroral Chorus I') and the data files of the Listening Guide. The WR-3 remains very popular and in use worldwide. This popular 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). If you prefer, please add $25 to the $100 WR-3 price and I will include one of these great antennas in the box along with your WR-3 and the WR-3 CD.

This great antenna is 10 section, 49-inches/136 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 too because the coil is in series with the antenna (and not shunted)! You can either order it from ALF Enterprises, 18933 59th Ave NE, Suite 114, Arlington, VA 98223, (360) 403-4840, for US$19.00 plus shipping via USPS and sales tax if applicable. (408 La Cresta Heights Rd, El Cajon, CA 92021, USA). Many people might have their own whip antennas, and so the antenna can be *optionally included* with your WR-3 if you need one and prefer not to order one yourself from another source.Ī very popular telescoping antenna which works excellently with the WR-3 is the 'Super-Stick II' 2-meter 5/8-wave made by Smiley Antenna Co., Inc. WR-3's manufactured since the spring of 2001 now 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 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. 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. In the spring of 2001, two modifications were made to the original WR-3 circuitry - the addition of 2 LC (inductive-capacitive) filters replaced 2 RC filters and sensitivity has been increased along with considerably lower internal circuit/temperature noise). The WR-3 is a self-contained, hand-holdable unit with two LC filters. Here is information about the WR-3 (made beginning September 1991): 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 this current Solar-Cycle 23 peak, and the recent upsurge in VLF phenomena to be heard now and for the next couple of years during the unstable and volatile downside of the solar-cycle!: The address will remain stable, as will QNET.COM addresses. Note: Please bookmark as a change in the site host will soon be made (dropping TRIAX.COM because of the increasing unreliability from Firstworld, Inc. We're at or just past Solar-maximum, and there are a great deal more natural radio sounds to be heard-join in the fun and discover the World of Natural Radio Below 10 kHz!
