There seemed to be several versions of the black microphones, 6- and 8-pin, three of which said Kenwood and one was an obvious Asian clone without the Kenwood label. We then searched ebay for Kenwood KMC-30 microphones, where the mike purchased was shown, stating "8-pin OEM KMC-30 microphone" for $22. Since it originally did not list the TK-6110 in the long list of compatible Kenwood radios, many of which were more recent production than the TK-6110, we concluded that the grey KMC-27 mike was the only original equipment issued mike for the TK-6110, but that the KMC-30 8-pin mike was to be used as an improved replacement mike for the TK-6110. The mike we finally agreed sounded the best was the 8-pin OEM KMC-30 mike from ebay seller 2010lindawang. Here's a photo montage of this microphone. Click on it for a larger view.

We feel the black KMC-30 Kenwood microphone definitely delivers crisper, more robust, and pleasantly intelligible audio than the stock grey KMC-27 microphone with its more range-restricted and muffled audio, especially when operating through a repeater. The KMC-27 mike may be perfectly fine for base station use with optimal conditions, but when you really need to get the message through, the KMC-30 punches through all the mobile noise.

Some people found the Kenwood KMC-30 mike gave better audio than the stock KMC-27 grey mike, which sounds muffled and hollow by comparison. Some say this mike is not OEM, but a clone, but for $22 including shipping from ebay, we thought it had better PTT action, the board looked OEM, the case was light plastic, but felt comfortable, and the audio was the best of four Kenwood mikes tested (others were KMC-27, KMC-35, and KMC-36.)

Our experiments with microphones, along with other hams in the area trying different microphones, encouraged us to bring out a pile of Kenwood Microphones. We tried several mikes including the original KMC-27B (black dot), the KMC-27A (red dot), KMC-35, and KMC-32 (DTMF) on a TK-690H at home while several people listened. We connected microphones at random without saying which one was being used, switching back and forth frequently and also used more than one sample of each model.

Just about everyone said the KMC-27B (black dot) was consistently the worst of the bunch. Surprisingly many liked the KMC-27A (red dot). The red dot means it has electronic noise canceling using a hole in the rear of the housing that supplies audio to a second mike element. Most agreed the KMC-35 sounded better than the KMC-27B. The surprising winner was the KMC-32 DTMF mike that we used in the car. We never expected this to be the winner.

Amateur 8-pin Kenwood mikes are not wired quite the same as commercial 8-pin Kenwood mikes. Using an amateur mike on a commercial radio or vise versa may cause damage to either the radio or the microphone.
