Astro Quantar Speaker

[Dover IT]

We have Astro Quantar repeaters and the ones that are analog I have no problem listening to the audio from the internal speaker. But the ones that are astro all I get is static from the internal speaker.
Is there a fix for this or is it the digital... We spent alot of $$$ and I cant listen to our units when im in the equipment room.....

Hate to tell you this but quantars do not decode Astro. They merely rcv the data and transmit it but no internal way to listen to digital sig.

You will not be able to listen to digital without a big expensive DIU connected to the Quantar.

Thank You,

We have DIU's on all of our receivers. Can you advise on what we need to do to listen to our traffic in the equipment room...

As I understand it, you would have to "listen" to the output of the DIU which is probally 'phone line' levels.

You would need an amplifier with a bridging balanced input.
Balanced because the 'phone line' is not refferenced to ground. Bridging so the amp does not load the line.

There are 3 ways to listen to the recovered ASTRO audio in the DIU3000: 1. Plug in a handset on the front panel of the DIU3000 at its RJ-11 handset jack; 2. connect an external 8 ohm speaker to the rear connector on the DIU3000; or, 3. listen to the speaker on your console or desk set, which is connected to the DIU3000 via either a short V.32 connection, or a phone company provided 4-wire VG 3000 private line.

Hope this helps.

To be a bit more precise, you need a VG-3002 (Voice Grade) Type 5, 4-wire dedicated circuit between the Quantar and the DIU3000, which in turn connects to your console. This arrangement allows the digital Motorola proprietary ASTRO 9600 signaling to be carried between the DIU3000 and the Quantar ASTRO modem, as well as analog voice in support of so-called "mixed mode" operations (e.g., ASTRO voice and analog FM).
