21 Audio Enhancement RXSHARE Audio Switch for Multi- and Single-Operator Contesting In the heat of a contest, serious competitors are always looking for an edge that can push them to the top. The experts at DX Engineering understand the hurdles contesters face, especially when a pair of operators need to hear the same receiver outputs. The RXSHARE Audio Switch gives two operators complete control of the specific audio they want fed to their stereo headphones, while either operating two separate radios or one shared radio. This means better coordination, fewer interruptions, less fatigue, and more QSOs. Each operator controls a three-position switch that allows them to listen to one, the other, or both channels of audio. These selections can be changed independently by each operator thanks to the unit’s silent rocker switches. In “Multi-Two” or “Multi-Single” contesting, the RXSHARE lets one operator hear when a new station is ready to be worked or when the other operator is going to work them. Using the RXSHARE in the “Separate Radios” mode, each operator may choose to listen to Radio 1 audio or Radio 2 audio in both ears, or either operator can listen to the audio from both radios in each ear. In the “Shared Radio” mode, the RXSHARE provides a convenient way of splitting the audio output of a single radio. For single-operator/two-radio contesting, the operator can listen to the same audio in both ears from a single radio, or hear the audio from each radio in one ear for simultaneous CQ-ing and tuning for new contacts. Advanced operators can even manage two pileups at once on dif erent bands. The sturdy, stainless steel RXSHARE (10.50" W x 2.50" H x 3.25" D) features a clearly marked front panel and two sets of stereo headphone outputs including 1/4" (6.35mm) and 1/8" (3.5mm) stereo jacks to accommodate headphones or headsets with either type of plug.

It delivers bhi’s latest noise suppression technology, and is small and rugged enough to be tucked into a duf le bag. The module is designed to work with headphones, but may also work with a compact, portable external speaker. A front-panel knob allows you to fine-tune your noise cancelling level. BHD-COMPACTINLNE Compact In-Line DSP Noise Eliminating Module ........$279.99 Ground Breaker RFI Blocking Device You’ve checked your connections, experimented with dif erent power supplies, and upgraded your ground system. Still have RFI? Then put Ground Breakers to work. These nif y devices totally isolate the ground of your accessory audio equipment from those of the radio system. Line level units can handle 500 mW for the 8 Ω model. To install, simply plug the Ground Breaker into the appropriate socket on your radio and then plug in the audio accessory, such as the digital signal processor or powered speaker, into the socket on the Ground Breaker. Available for mono and stereo applications. BHD-GB8M 8 Ω Mono Ground Breaker .....................................................$48.99 BHD-GB8S 8 Ω Stereo Ground Breaker ...................................................$48.99 Dual In-Line DSP Noise Eliminating Module Many new radios (including most SDRs) have stereo audio capability. bhi’s Dual In-Line accepts two separate audio signals to allow for stereo output. It can also be fed by two dif erent signals, which is handy if you run multiple radios in your station. The dual outputs also mean you can monitor two separate signals at the same time. It also has separate 7W audio and headphone outputs. It’s an ideal DSP noise cancelling module for club events, Field Day, or multi-radio DX stations. BHD-DUAL-IN-LINE Dual In-Line DSP Noise Eliminating Module ............... $279.99 BHD-DL-STD1 Dual In-Line Mounting Stand ..........................................$17.59 Parametric Receive Audio System (PRAS) Using three separate equalization controls, Heil’s Parametric Receive Audio System (PRAS) enables operators to enjoy clearer voice articulation in receive audio through more precise adjustments of midrange frequencies. The unit allows operators to adjust the parametric midrange filter from 400 Hz through 4 kHz, and control the presence of these midrange frequencies plus or minus 15 dB. Combined with a low-frequency filter down to 160 Hz, and a high-frequency filter up to 6 kHz, the PRAS provides operators unparalleled control and quality of their receive audio. Heil's two-way Powered Speaker (HPS-5), sold separately, is specifically designed for use with PRAS. The speaker features a low-distortion, highly ef icient Class D 24 watt amplifier that drives the specially designed 5" low-frequency driver with a 3" magnet mounted in a resonant sealed enclosure. A passive extended crossover drives a 2" high-frequency tweeter.
