AOR ARD-300

Post by freqwaves » Sat Jul 26, 2014 1:28 pm

I came across this unit while looking at scanners sold by Andrews Communications.
Is anybody currently using one of these? There not cheap to buy & you need a compatible scanning receiver to use also.
"All-new external DIGITAL multi-mode voice decoder!!
Decodes APCO25 voice signals! Decodes dPMR, NXDN and popular amateur radio digital voice mode from Alinco, Icom and Yaesu!
Compatible with AOR "legacy" receivers, e.g. AR-8600Mk2, AR-5000(A & +3), AR-ONE and newer AR-2300, AR-5001D & AR-6000.
Supports any brand's receiver or scanning receiver which has a 10.7MHz or 45.05MHz IF output."

Thanks, John.

Sounds almost too good to be true - though I do note that it is missing DMR/MotoTRBO etc. I'm keen to give one a burl!

Had to look up the difference between dPMR (NXDN) and DMR (TRBO)

DMR uses 2 slot TDMA - requires 1 repeater for 2 x 6.25khz Sub channels
dPMR uses 2 slot FDMA - requires 1 repeater for each 6.25khz sub channel

Consequently dPMR is not spectrum efficient in comparsion to DMR.
As far as I can figure dPMR and NXDN are the same

I can't remember, which one was it that uses four slots? Is it TETRA or something else?

Can't even remember where I read it now, so much water has passed under the bridge since I was playing with such things.

Grant that's correct. In fact, given that DMR can support two channels simultaneously, it's more cost efficient as well as cheaper too. We are looking to set up a DMR repeater on 70cm in Sydney.

This receiver now comes with a firmware upgrade for Mototrbo. ARD-300 sells for $1199, then you need to buy a AR8600 MK2 at $1199 which adds up to $2398.
You might as well buy a AOR AR-DV1 for $1999 with all features in one unit.

Scanner with discriminator tap + free download of DSDPlus 1.101 is much cheaper
