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
