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.
