EF Johnson 5300 not making sound when receiving

[chimera388]

I just finished installing my EF Johnson 5300 in my POV, and I've run into a problem. When the radio is receiving a transmission on any frequency, it doesn't seem to activate the speaker. The green light goes on indicating it is receiving, but no sound comes out of the radio. I know that the speaker is working, because if I put it on scan, I head RF noise as usual. Additionally, I don't hear any beeps when it powers on, or when I press buttons. Transmit works fine on both simplex and duplex channels. Any ideas?

The 5300 series radios require a small jumper on the accessory pigtail/dongle to activate the internal speaker. If the jumper is missing or not connected to both pins, nothing will be heard.

Thanks John. I checked the jumper and it's in the 1-3 position, which should be correct for internal speaker.

I'd try an external speaker (pins 1 and 2) just to confirm that the radio is working properly. Another possibility, which I'm sure you've already considered, is the tone squelch setting.

i know its not a johnson but i have a moto cm-200 that had no audio via the internal speaker it was supposed to have (has a grill for it)
turns out that radio was available with a no speaker option even though it has a face plate for it and the kicker is the speaker is in there but they put heat shrink on the wire ends going to the speaker
must have been cheaper to leave it in there then make a run of fill plates

Never seen that before…always seen disconnected speakers as the later commercial radios didn't have the circuitry to enable/disable the internal speaker when an external was used like the radius chassis radios.

The OP stated that noise comes from the speaker when scan is activated, not a speaker problem. In the programming software the beeps can be turned off. I would look at the CTCSS (aka PL receive tones) are correct). The programming for the 5300 can be confusing when working with multiple zones but setting up an individual channel is pretty easy. There is a problem with the 5300 not receiving which can be a defective RF board. I had three 5300's with no RX, just got one back from our depot service, need to send the others in. BTW what series is the 5300? You need the correct programming software for the version radio that you have. You can map one of the push buttons to monitor, when the button is pressed the radio reverts to carrier squelch on receive.
