W2IHY 8 Band Equalizer and Noise Gate

Date Posted By Category User IP
2020-01-12********Audio Processors********
Finally, professional audio processing technology is applied to the unique requirements of amateur radio operators! The W2IHY 8 Band Audio Equalizer and Noise Gate is an easy-to-use, sophisticated unit loaded with high-performance features. This thoughtfully-designed, quality- constructed station accessory performs three important functions, all in one good looking, low- profile package:

- The Audio Equalizer gives you sophisticated control of the tonal qualities of your microphone and, thus, of your transmit audio quality. The range of equalization possibilities is virtually unlimited, letting you custom-tailor your audio just the way you want.

- The Noise Gate is the long-needed solution for noisy operating environments. Background noises that used to make copy difficult or unpleasant on the other end of the QSO are eliminated or greatly reduced.

- The Universal Microphone and Radio matching capabilities are terrific. Match practically any microphone of any impedance to practically any radio's microphone input. Adjust the wide-range input level for optimum drive to the built-in microphone amplifier. Adjust the output to give your radio the ideal signal level for best performance of microphone gain, alc, compression and smooth VOX operation. A comprehensive selection of microphone jacks means plug and play for most microphones. Instant microphone compatibility with Yaesu, Kenwood and Icom microphones via a 3 position switch.

JPS NRF-7 audio processing/Filter

Date Posted By Category User IP
2020-01-05********Audio Processors********
SOLD!This MINT JPS NRF-7 audio processing/Filter, unit provides a number of functions that improve the receiving conditions for radio amateurs and short wave listeners. The unit reduces or eliminates atmospheric (white/pink) noise and multiple heterodynes. A dynamic peaking filter reduces the effect of white noise outside the audio bandwidth by creating individual and constantly-varying passband filters around speech components. This reduces white noise by dynamically excluding those portions of the passband that do not contain speech. The LED tuning indicator provided is usable in all filter modes to show when the desired signal is within the filter passband and operates whether the filter is engaged or not. The unit operates on radio receiver audio outputs then provides its own clean audio from the built-in amplifier to an external 3 - 8 ohm speaker.
Excellent condition, no marks or damage. Works 100% and is one of the finest audio
notch/bandpass filters available. Heavy and built like a tank $75.00 shipped free.
Postal M.O. or personal check. Thanks for looking, Roger, K8CIX

Radio Shack DSP-40 $65 Shipped

Date Posted By Category User IP
2019-12-14********Audio Processors********
SOLD!I have for sale a Radio Shack DSP-40 unit, model number 21-543. Works fine. Non smoker. It is close to new, comes with BOXED and and all accessories.
These DSP units are absolutely amazing at taking out heterodynes- much better than the built-in DSP in all my newer radios. The tones simply disappear. They also excel at setting a restricted bandwidth to reduce interference in both SSB and CW. The narrow bandwidth in CW mode is the next best thing to having a narrow CW filter in the rig. These units do not remove general background hash.
