  • eric kw Jun 01, 2008

    hello Thanks for all your help - you guys were right with the speaker being defective. I had a 4 ohm marine box speaker - this vhs had no port in the back but it did have two wires for the external speaker - green wire,yellow wire- hooked up speaker and it works just fine now. again thankyou very much

Hi,

No RX audio could be caused by:
1. defective internal speaker;
2. defective audio IC;
3. defective suelch IC;
4. defective volume or squelch controller;
5. defective front end (RX);

in some case, it could also be caused by:
6. defective mic switch/cable;
7. defective earphone/external speaker jack.

Of the above, often the culprit would be the speaker being small. An easy check is to plug in an external speaker or headset.

All others would require knowledge and familiarity of electronic components and circuitry, use of a DVM and a soldering iron.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    with the indulgence of IB4G2008,

    Should the internal speaker be determined to be defective, an exact replacement would not be that readily available. However you can get a substitute from your local electronics parts store. The only limitation would be the physical size since the internal speaker would only be 1.5 to 2 inches in diameter with a depth of less half an inch. It wold be to your advantage to bring along the defective speaker (if determined to be so) for an as per sample purchase. An alternative is to use an external speaker as earlier posted an example of which is shown below.

    Another alternative is to use the non powered part of a computer speaker pair.

    the external speaker jack is normally at the back pretty near the red and black power cable and/or the antenna connector.

    BTW, the plug used is a 3.5mm baby phone, mono.

    assuming they are of the right size (3.55mm), yes, but you might have to wiggle them a bit since I expect them to be stereo (not mono). if the black/plastic insulator band is only 1, it is mono, but if 2, then it is stereo. Either will still work other than as earlier stated you might have to try fiddling how they it is plugged in. Might I suggest you try plugging it in wearing the headphones/set, the squelch all the way down and the volume at 10'clock position.

    secondarily, you may find that the squelch, when out of calibration, will cut off the amplifier completely..can you cut the squelch to zero? also, key the mike and see if you can detect any kind of volume, at all..

  • Patrick Michaels
    Patrick Michaels May 25, 2008

    i wouldn't take that approach, until I was absolutely sure and certain that it's not an amplifier settings or operational issue..try those two approaches, first, and then report back..

  • Patrick Michaels
    Patrick Michaels May 25, 2008

    that's a big maybe. where'd you buy this unit? local boating supply right? is it under warranty?

  • Patrick Michaels
    Patrick Michaels May 25, 2008

    ok..well..then it's highly possible that the parts are hard to impossible to get anyway..you might consider calling the place you bought it from, and asking who does service on this unit...these are tight little buggers, and takes a good sense of humor and patience to unlock and work with..

    didn't see one immediately on the specification manual(see my other post)..so unsure if this generic understanding would apply to your unit. www.raymarine.com is where I found the most useful information

  • Patrick Michaels
    Patrick Michaels May 25, 2008

    when I looked at that service and users manual, I must have missed the external speaker port..maybe it's buried somewhere in that document?

When i turn My Solara DSC VHF radio on it no longer beeps . I cannot hear any squelch or pick up any channels. Is this my speaker that has gone.


To test a speaker, you'll need either a digital multimeter or an analog multimeter that can read measurements of resistance (Ohms)
First isolate the speaker from the amplifier (meaning, remove the wires attached to the speaker terminals).
Set the meter to Ohms (Omega symbol).
Take the meter test leads and place each one on the speaker terminal (make sure the test leads do not touch each other)- there is no polarity to this test so it doesn't matter which test lead goes where on the speaker terminals
For an 8-Ohm rated speaker, you should get a reading of about 6-7 Ohms (approximately 15% of the speaker rating)
For a 4-Ohm speaker, around 2-3 Ohms
and for a 16-Ohm speaker, about 8-Ohms
If you can an infinite reading (make sure the test leads are not touching each other) other wise, if the test leads are not touching and you get an infinite reading, there is a short in the voice coil; speaker is defective.
OL reading on the DMM, or O Ohm resistance on analog meter, broken wire connection inside the coil= open voice coil and is defective.
If you get the proper reading on your speaker, the problem IS NOT with the speaker

Yaesu ft-857 squelch problem


Your RF gain control needs to be turned all the way up to be able to receive signals and if you are on one of the HF bands like 40 meters or any HF band the squelch control needs to be all the way off! You do not use squelch on HF! When on VHF or UHF then you would rotate the squelch control just to the point that the background noise stops and go no further. Higher squelch settings will only block weak signals and your radio will be deaf! Squelch control rotated just to the point the background noise stops! NO SQUELCH ON HF. Turn the squelch all the way off on HF!

Icom m36 will not receive. Speaker makes noise with squelch all the way up but just won't receive anything including weather.


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.

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

My Ranger2950 has no sound??


Have a look here for info about the Ranger 2950. This is an Amateur 10 & 12 meter transceiver that enjoy some popularity due to its ability to be modified to work on the 27Mhz Citizens Band.

Make sure the Mode is set to something other than PA. A few of the first things that come to mind is the Volume, Squelch & RF Gain settings. The Volume is straight forward - choose a setting in the middle to begin. Next, set the squelch. Most radios have the squelch open when set fully counter-clockwise. As you move the squelch to this position, sound should be heard from the speaker if a signal is present. As long as there is an antenna connected, the radio should "hear" noise. If you do not hear anything, leave the Squelch fully CCW and try varying the RF Gain fully in one direction. If you still hear nothing, set the Squelch to the fully clock-wise position. Adjust the RF Gain to the opposite direction. At this point, you should have heard something - even if just static hash. If not, the volume control may be dirty. Disconnect power and rotate the volume control back and forth several times to dislodge any dirt on the volume wiper inside the radio, and try again.

Make sure that the Ext Spk jack does not have a plug inserted as it will defeat the internal speaker. Likewise, if using an external speaker, make sure it works.

Good luck!

Have power to my Ray53 DSC VHF on my boat but no sound


Sounds like a bad speaker. Try plugging in an external one and see if that works if so replace the bad speaker.

It sounds like your speaker has failed. I would recommend replacing the speaker. You can take the radio to a marine electronics repair shop for the repair and it should be about $75 - $100. If you have any other problems please email me: kevin@sun-me.net. You can always send it to me and we can repair it at my shop.

Not receiving information


The same thing happened to me, and I'm just hitting the two-year mark with this thing. I tested it using the aux speaker leads and that still works. So it is only the little front-panel speaker that is broken. And I checked the leads on that little speaker, and they seem fine. So it is the little speaker itself that broke. Easiest repair is to connect the aux leads (red and brown) to another speaker.
