Motorola XTS 1500 audio adapter for an external speaker

[tpone234]

Good morning,
I just purchased a used Motorola XTS 1500 to which I’m going to have programmed and use as a mobile scanner for my vehicle. I purchased an audio adapter to possibly hook up to an external speaker. I noticed the adapter has two jacks, one being a 3.5 mm and a smaller second one. When I plug the 3.5 mm jack from the external speaker it made the radio start to transmit. Unfortunately I am unfamiliar with this side of the XTS portables.
If someone could shed some light on this, then I’d appreciate it. Possibly a adapter with a smaller jack for the second plug? Thank you in advance for any help with this issue.

I suspect issue w/3.5mm jack is is looking for a 3 wire plug. (The ground portion of a 2 wire plug has a tendency to short sleeve to ground which is likely the ptt signal.) Also look at 3.5mm jack to see if it is threaded. Some Moto assys are threaded and a std 3.5 may not seat correctly.

is it a moto OEM external audio adaptor?

Sounds like you are using a two pin speaker mic adapter.

You need to know what kind it is, and figure out what the pinout is. Just because the plug will fit in the hole doesn't mean it's the speaker output. If it's wired like the standard Kenwood 2 pin setup, the 3.5mm jack is three conductors. The microphone and PTT circuits are on there. Sticking the speaker plug in there went across the PTT connection and keyed up your radio.

The smaller 2.5mm jack will have the speaker on it, if it is a Kenwood style two pin adapter. So you either need to cut the plug off your speaker and replace it with a 2.5 mm plug, or you need to find an adapter.

-IF- it's wired as a Kenwood style or similar adapter.

Thank you for that info. Do you have a link you can send me with the correct audio adapter I have a Motorola XTS 1500. Have a speaker that has a 3.5 mm jack I bought an adapter to 2.5 mm, but when trying to put it in the smaller jack jack is yet still too small. I don’t think I have the right audio adapter

If you get a standard speaker mic, they have an earphone jack on them. You can jack right in there and get your audio.

or, buy an old speaker mic, cut the speaker/mic off and just steal the speaker leads.

Here is one option, if the XTS is what you really want. (Scanning is not their strong point.)
