Can Trx-1 decode dmr/nxdn signal data ?

Post by cartman » Wed Mar 29, 2017 6:10 am

For TRX owners - i was wondering is it possible for the TRX-1 to be programmed to show dmr/nxdn signal data for a frequency range when there is no voice present. I have noticed that the TRX-1 skips over the dmr/nxdn data channels/pulses in search mode. I am hoping that i may have a setting in the wrong mode. Having the TRX-1 do that would be helpful in searching for new signals

I am used to the Dsd software + discriminator tap which shows channel data and decodes voice if present

Hi Grant,

I haven't been able to get mine to do that, only stops on DMR when voice signal detected. Be interested to hear other owners experience.

Regards
Kev

BUILT-IN DISCRIMINATOR OUTPUT - provides raw discriminator signal to third party signal decoding software w/o risky hardware modifications
Saw this on the radioreference TRX-1 wiki
Might be able to run DSD alongside?

Update: i think so via earpiece audio jack.

You can via the Headphone jack, you can select it via the Radio or program it via the EzScan software. Can IF out via the Headphone jack, I have used it with DSD, Unitrunker and other applications fine! Just remember to find the correct audio volume setting for the software.
