On the ICOM M604 will not receive the weather channels, will receive other close radio's.

If it can receive some signals that are close to you, then the RF front end protection diodes are likely shorted. This would require someone with expertise in surface mount components to repair. Take it to a dealer and have them look at it.

You may have the CTCSS tone squelch enabled so unless a station you're listening to is encoding CTCSS tones, you won't hear the traffic you're expecting.

Hi Mike,

The manual for this radio (in Adobe .pdf format) is available for download directly from Icom America, free of charges.

Since the "AquaQuake" function works and you do hear static when the squelch is off, that is sufficient to let us know that the voice coil of the speaker is functional and should produce sounds with the right signal applied.

The first thing to determine is if you're close enough to another operating transmitter for the radio to receive a signal. One of the 10 weather channels the radio is capable of tuning should be close enough produce some intelligible audio from the speaker - assuming the squelch setting isn't set too high.

If a WX channel works, then you'll need to see if there's a VHF Marine band transmitter operating nearby. You might need to set another Marine band radio receiver up to verify that there is indeed a signal present on the particular Marine band channel that you're monitoring. A list of frequencies is published on pg 27 (of the manual linked above) in case you need to convert between channel and frequency to tune on a non-channelized radio.

Outside of that, there's little the end user can do without specialized test equipment, schematics and of course, training. Many shops will be happy to provide an estimate for repair when provided with a small bench diagnostic fee. This fee is usually applied towards an authorized repair by most reputable repair shops.

I hope this helps & good luck!

Probably not the squelch but the speaker on the VHF. These radios are famous for crapping out when getting wet.
Try listening to the weather radio VHF ch 01, 02, or 03. depending on your location and play with squelch.. Keep in mind they do make external speakers you can hook up.

1. Turn switch on side of radio to "ON".
2. Press "MENU".
3. Press "UP" arrow until "CHANNEL" is displayed.
4. Press "SELECT".
5. Press "UP" arrow until you hear the broadcast of your station.
6. Press "SELECT" to save station selection.
7. Press "MENU" to close menu mode.
To turn Weather/Hazard broadcast on again, press "WEATHER/SNOOZE".

Note you will hear only static on the channels not received in your area.
(FYI - channels are listed 1-7 on the left, and corresponding frequency numbers are displayed on the right side of display.)

At This Point You Will Receive Weather And Hazard Alerts Issued By The NWS.

Sorry, but your radio is limited to 16 channels in the 400-430 and 440-470 MHz ranges. The number of channels cannot be expanded, nor can the frequency coverage.

This sounds like you have the "Weather Alert" function turned on. With this on, the radio will check for an emergency signal on the weather channels about every 10 seconds.

Sound like you have an antenna issue. Try a different antenna with coax. If the problem is still there, than you have a problem with the radio. Icom makes really good marine radios but you could have a defective one.
