Kenwood KMC35 Microphone Mod to Improve Audio
|
After 8 years of working with them, and thousands of radios, Ive never noticed any issues with audio quality on those out side of faulty mics that had bad cords or were otherwise broken.

Yes, the new KMC-65 mics do sound better, however... On 3/26/2025 12:42 PM, John via groups.io wrote:
At least on the TKX90 mobile radios, removal of chip cap C10 (0.068MF) adds more highs to give more crispness, less muffled voice audio. This is located on the mike PC board with it's location marked. |

Yes, Bob, compared with the Grey KMC 27 mic, the black KMC35 mic does sound good. I am being picky. To me the gold standard mic audio is a Motorola SyntorX/ X9000 with the cap closest to the mic cord on the mic board changed from 0.047 MF to 0.33MF. The Kenwood 0.068MF cap deletion will bring a TKX90 radio close to that, but, if going through a repeater, the repeater audio needs to be flat from 300-2800 cps and no compression or clipping, to notice the improvement with the Kenwood mic mod, probably not the way Kenwood would have you set up a repeater.
