Seeing that P25 Phase 2 is almost the same as DMR, how do they do it?! Phase 2 will do the same as DMR, use time slot 1 only on simplex. It will work, just only one time slot - one user at a time.

The PAPA System (http://www.papasys.com/) has invited me to participate on their net this Thursday on D-PLUS REF012C at 8PM Pacific (0300Z). Apparently there is a lot of discussion about the UDR56K

Keep in mind that P25 II TDMA is only capable of network repeater operation (read that "trunked"). Simplex is not supported on Phase II, as there is no way to accomplish the sync requirement for 2

I haven't verified it, but it should be possible. Bryan

Well, if you don’t know how to “generate” data stream, decoding it is the first hurdle. Ie, when “dstar” first came into light, ICOM didn’t freely publish the TCP/IP stack, it had to

But... No transmit... I have seen it before, and its cool... For unlicensed folk who like to listen to police scanners. But I want to talk... and for that, I need the other half of the

Considering 3000, yes. P25 - IMBE P25 Phase 2 - AMBE I don't think the 3000 does IMBE. John D. Hays K7VE PO Box 1223, Edmonds, WA 98020-1223

But you said you would be using the AMBE Vocoder 3000? Which would not require the use of mbelib at all.

I am familiar with the package -- NW Digital Radio would not be inclined to directly support it, due to the following: Patent Issues with mbelib While DSD was intended to be patent-free, mbelib

Not sure if any of you have seen this: http://wiki.radioreference.com/index.php/Digital_Speech_Decoder_%28software_ package%29 Linux Based Decoder Software that supports: • P25 Phase 1 •

I was just thinking of 2 units to do P25 with!

That’s on the mobile side. BS is constant carrier even for empty timeslots. Format is TS1 – CACH – TS2 – CACH repeated.

> The UDR56K has the ability to support many protocols in software, limited only by modulation type, data rate and other ait interface limitations like TDMA. Is it capable of the 1.5 msec full tx

Larry, Repeater operation, the SHORT answer. Repeaters require full-duplex operation. NW Digital Radio is planning on releasing a Full Duplex Radio sometime next year pending response of our initial

Hi Bryan! Any chance you will have a P25 repeater available? Timeframe? Thanks, Larry WA7LZO

I'm ready to start doing some development also!

Hi Hutch, Short answer "no" ... Longer answer. You can use the UDR56K-4 in a few configurations to get on the D-STAR network. There will be an application that turns the UDR56K-4 into a 70cm D-STAR

It may be possible, but it is frowned upon to do so, except on a few dedicated reflectors which have Echolink (analog) connectivity. Some XRF reflectors do indeed have this and use an 'Analog

I missed this at Dayton. Can I use this with my analog HT and connect to the dstar network, or do I need an Icom dstar HT? 73 K9kjn

Hi John, We've been thinking about some of these ideas as well. In the design of the UDR56K-4 we really are shooting for the "sweet spot" between data rate, bandwidth, propagation, and utility. 70cm
