1 is the least amount of squelch and 9 is the most. 9 requires more ratio power to break the squelch than 1.

Squelch control of ic-2000 does not function


In what way. Does it never receive? If that's the case, chances are the CTCSS (Tone Squelch) is on. If it never mutes the speaker, the squelch circuit may be defective.

I would lke to know the reference code on the audio out put ic, used in the VHF MARINE IC-M302.


Quick description as per ICOM Manuals:
Quote
The AF amplifier circuit amplifies the detected signals to drive a speaker. The AF circuit includes an AF mute circuit for the squelch. AF signals from IC1 (pin 9) are applied to the de-emphasis circuit (R61, C89). The de-emphasis circuit is an integrated circuit with frequency characteristic of –6 dB/octave. The integrated signals pass through the high-pass filter (Q5, R62–R67, C90, C91) to suppress unwanted lower noise signals. The filtered signals are applied to the AF mute circuit (IC7B), and then passes through the [VOLUME] control (VR board; R1) via the “VOL1” signal. The signals are applied to the AF power amplifier (IC6, pin 1). The output signal from IC6 (pin4) drives the internal (external) speaker.
Unquote
I thus assume the IC you are looking for is the IC described as IC 6.
Data sheet availible online: http://www.datasheetcatalog.org/datasheet/sanyo/ds_pdf_e/LA4425A.pdf
The IC is a Sanyo LA4425A. A 5W Power amplifier.
