Try adjusting the center frequency (shift) or decreasing the Low Cut (FL) and High Cut (FH) by similar amounts. In general, the important spectrum for speech is 400 - 2200 Hz while simply "dialing down" the width causes the Low Cut to raise too quickly. The K3/K3S nominal 2.8 KHz bandwidth is set at 100 - 2900 (FC = 1500). Simply dialing the width down to 1.8 KHz results in a passband of 600 - 2400 Hz (FC remains 1500 Hz). Adjusting FC down to 1250 or 1300 Hz will greatly improve the "clarity" of SSB. In addition, the K3 has a flat audio response while most rigs have a slight raising characteristic (about 3 dB/octave). You can emulate that response using the RX EQ. Set 0.05 = -16, 0.10= -16, 0.20= -6, 0.40= 0, 0.80= +3, 1.60= +6, 2.40= +8, 3.20= +9 and the audio will emulate "other rigs". You can also set 3.20 to -6 to minimize high frequency noise. 73, ... Joe, W4TV On 10/18/2017 8:07 PM, [email protected] wrote:
I’ve found the audio with narrow filtering is much “clearer” to my ears (using a Heil headset) on my Kenwood TS480 than on my K3. I spoke with another person who owns both radios and he finds the Kenwood audio crisper, less “mushy.” My K3 is a great radio, but I’d sure like to hear better. Is there some adjustment I’m missing? ______________________________________________________________ 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 Message delivered to [email protected]
