Nxdn

[dozerman2009]

i was wondering if their is a way to receive nxdn i am using a radioshack pro 106

No radio can do this out of the box - yet.

However, with a discriminator tap and DSD software, the answer is yes, you can. See this forum for more info

It's not something you buy, it's something you do. It's a modification to your radio.

Is is possible to purchase a Kenwood handheld and program it so you can monitor NXDN frequencies? Or will the local shops not sell Kenwood NXDN radios to the public?

 

[dozerman2009]

i believe you can buy them you just can transmit

Am I not correct in saying, that if one was to purchase a Kenwood radio ( from a radio shop and individual that they are are familiar with ) and have the radio freqs installed, and the radio put in NXDN mode, they can receive the NXDN radio transmissions - same as with P25, and Mototrbo.

Kenwood will happily sell you an NXDN radio, as will Icom, who also uses the NXDN protocol.
You will need to know what frequencies you need access to:
VHF and UHF are available from both manufacturers.
Kenwood also makes 800MHz radios and 900MHz radios. No 700MHz.
You will need to know if they are using 12.5KHz NXDN, in which case you would need Kenwood, as Icom only supports the 6.25. If they are using 6.25, then you could use either.
You will also need the programming software.

I've got a few hundred Kenwood NX-410's and NX-900's at work. Good radios, and you'd be able to get those in the $700 range, a bit cheaper if you wanted VHF or UHF.

Programming software for the Kenwood radios (KG-111) is really easy to use and nicely set up. Figure another $100 or so for software and cable.

By the time you get accessories, radio, extra battery, software and cable, figure you'll be out around $1000.00.

These radios can be programmed for receive only, so you'd be OK there.

VHF and UHF models of the Kenwoods will do the respective amateur bands. They will do both wide and narrow FM, also.

I have no personal experience with the Icom's.

Oh, and if it's trunking, then you have some more issues:
Kenwood and Icom trunking are not the same and are not interchangeable.
From my recollection, if the system you want to listen to is running trunking, then you are pretty much out of luck without the system key. I don't think you can monitor a single repeater or group of repeaters and be able to listen in on a trunked system like you can with analog. You either have to have the system key, or you are out of luck.
No agency should be handing out their system key, so very unlikely you are going to get it unless you have a really good reason.

And all the Public Safety agencys that use NXDN - P25 - Mototrbo...ect ; and think they are "secure" in talking.

I have a former co-worker; whom has all the programming equipment to program the Fire Department radios, of the Fire Department he is on. Motorolas. See how easy it is to listen in on so called, and self defined - "Secure" radios.

Makes ya want to laugh don't it.

That is my understanding to. But with "Trunking capable" scanners - why worry about listening into one repeater.

You either have to have the system key, or you are out of luck.

Again. No need to worry about the key, when you have trunking capable scanners.

I'm told at my job only the director of security has that and they change it every week. Not sure if that's Bull$ hit or not.

Why. Right off the top of my head, I do not see it as a logical or tactical purpose.

That is all correct, however the original poster was asking about NXDN. I was replying how he "could" purchase an NXDN capable radio. To program one of those for trunking, you need the system key.

As you replied, not so with a trunking capable scanner. At this time, however, there are no commercially available NXDN capable scanners available. Discriminator taps and outboard software will decode it, but I don't know if any of them can de-trunk yet.
