- ===== AUDIO MODIFICATION FOR ICOM IC02 AND IC04 RADIOS =====
- ------------------------------------------------------------------------------
-
- This audio mod works on the 02 and 04AT. It increases the level of audio, as
- well as rolling off some of the lows. Sounds real nice. It involves the
- circuit around Q105.
-
- 1. Replace C119 with a .01 uF cap (disc ceramic is fine).
-
- 2. Parallel R131 with a 1 uF cap (use a tantalum cap).
-
- 3. Parallel R132 with a .01 uF cap (disc ceramic is fine).
-
- This is not the same mod as the one International Radio is advertising, which
- involves changing C117.
-
- I tried an AB-1 Audio Blaster from Engineering Consulting, and was very
- unhappy with the results. I am very pleased with the audio given by this mod
- (much cheaper too!).
