I now use an MFJ 616 outboard variable equalizer tailored for the audio spectrum. It connects between the audio out of my K3 and the speakers.
The RXEQ built into the K3 is capable of about 36 dB of combined high frequency boost and low frequency cut. This won't be enough to compensate for really severe hearing loss, but it can an effective solution for the majority of folks. As a starting point, set the four lowest bands to maximum cut, leave the fifth band at zero, and the remaining bands gradually increasing in boost until it sounds good to you. Those with more serious loss will usually want boost be greater on those higher bands. The most important octave for speech is 2 kHz, 1 kHz is next, then 4 kHz. So with severe hearing loss, you will generally want the top three bands up full.
I would do this before I would consider an external equalizer. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
