Look at any good audio or radio handbook and you will see that for maximum intelligibility on the radio, you DO NOT want response below 350 Hz. That detracts from hearing the maximum clarity of signal and as someone said simply wastes power. Speech response for optimum communication extends from 300 to 3kHz. Western Electric and Bell Labs proved this decades ago, and it is still the better way to set up a radio for audio response for ham communications. Remember, hams are to use the minimum power and bandwidth needed for a given mode, NOT have "high fidelity". Stuart K5KVH |
