Great Investment!  Time owned: 0 to 3 months
If you do this mod, you'll need to crank your audio gain way back as it's MUCH more sensitive than the D-104's crystal element. Using it with the gain at the original settings will definitely distort your audio. My 5100B's modulation meter now barely moves, but I'm getting outstanding audio reports regardless. I'd say it's definitely worth the $22.95 cost.

Great product  Time owned: 0 to 3 months
Installed the upgrade kit in my D-104 today (TUG8 base). Tested great on HF, even got a sound byte sent back to me (wav file) from a fellow ham on 40m.
Then tested same on VHF FM simplex with a fellow local ham and it sounded great to him. As with ANY condenser element, cut the mic gain way back to keep from over driving the audio. NO PROCESSING.

Great Kit with Great Support  Time owned: 6 to 12 months
The D-104 was made in many versions, but the support in puzzling my version out was superb. Works great on my Elecraft K3. The audio is excellent.

Great & cheap  Time owned: 3 to 6 months
Am using a d-104 and the w2eny electret mod with a pro2. This inexpensive kit comes with very full instructions with the kit. It is a great match for Icom rigs. I am getting good reports on the air, and AxB testing in comparision with the hc-5 cartridge of my proset plus yields friends reports that they can hear very little difference between the two. This is a best buy and a real keeper in the shack. 73. Doug

Great improvement in audio quality for my old D104  Time owned: 0 to 3 months
The instructions to install this kit are very clear with pictures. I installed it just as the picture instructed me. I got immediate feedback from the gang I talk with on 75 meters. They reported that I gained the low end response that the D104 is famous for missing.
