Motorola MotoTRBO Test - DMR vs Analogue FM on VHF

Testing DMR vs Analogue FM in a moving environment.

I'm using a Motorola DM3600 mobile set to 5W output, antenna on the vehicle is a Panorama magmount with a VHF whip.

The RX radio is a Motorola DP3400 connected to an external 0 dbd Omni at about 12m above ground, connected with around 5m of RG213.

DP3400 was set to scan two channels, one digital and one analogue so you can hear a fair comparison as transmissions were less than two seconds apart.

In my opinion, the radio does a very good job of cleaning up scratchy signals and copes well with RF noise too.

I left the noise cancelling software checked by mistake on the PC Line In, so that's actually smoothing out some of the noise on the analogue audio.

Both of these radio's were on early firmware versions, they have since been updated to the latest and I will be testing again to see if audio is better still.
