P25 and Opensky

[Fire125]

Hi,
is it possible to patch P25 to Opensky using Kenwood NX series and Harris M7300? Our dispatch is able to but we are trying to do it ourselves in the truck. Thanks

I imagine you could using an ACU

Google acu 1000. It’s a device that both radios would hook to which would then allow you to patch groups/freqs from each radio. It wouldn’t be a cheap thing to do. There may be cheaper options but if your looking to just directly connect your two radios I don’t believe that’s possible.

I'll look into thanks a lot!

Are both the OpenSky and P25 system part of the same VIDA platform? If so, this is a console patch with transcoding at the system level. If they arent, the next best method would be with a donor radio from one into the console system of the other. I would do radio to radio patches in the field only as an absolute last resort both due to reliability as well as the fact that an operator of a Gateway device that isnt very well trained can cause more problems than they solve. Further if two Gateway devices get turned on, you effectively end up rendering both systems useless.

The NX-5000 has a DB-25 connector on the rear. From the connector you can pull audio out from the radio, push to talk, audio in and a COR (Carrier Operated Relay) that can be used to trigger the PTT on the OpenSky radio.

You can use something like the ACU-1000, or you might be able to build your own. Just takes some work to get the levels correct.

Also, running from Digital to analog then back to Digital usually just amplifies any inherent crappyness in the digital-ness of the audio.

Thanks a lot. I'll check into it and will update it here.

On a few events over the years we did use the ACU-M to patch/link opensky to P25. It will work but isn't the best as others have said. The ACU-M is nice for a truck as it can be managed completely with push buttons.

For your truck unit check out the ACU-T. I'm just getting ours setup.
