eyes00only,mThanks. I'm not sure how DMR & NXDN work as this is my first scanner that receives them. Unfortunately they're about the only thing the TRX1
is good for in my area. P25 Phase I, Phase II. and Simulcast suck with the scanner.
I now have a brand new TRX-1. It reliably decodes DMR traffic on several repeaters and produces very good quality audio. I can also pick up nearby units on their repeater input frequencies and the TRX-1 displays "DMRs".I just searched for a short time while waiting for someone in downtown Denver. I do think I heard audio when DMRs was displayed.
I was probably very close so it probably was a repeater input or simplex.
Your TRX-2 decodes simplex perfectly in the Tune mode? FYI, my TRX-1 decodes nothing.It seems that the info about not using slot numbering in simplex are correct. The TRX-2 indicate slot 1 whatever slot I use in simplex and it decodes simplex perfectly every time with a DMRs indicator and displays all the traffic info. It does this with both DMR ticked or unticked as a valid mode in tune mode so it will automaticly switch to DMR from analog and I cannot monitor in analog mode. So there's another bug in the Whistler firmware.
The Uniden BCD536 doesn't decode the simplex signal at all and treats it as an analog signal. I have decoded DMR uplink to a repeater succesfully so it will anyhow work in that mode.
Also FYI:Your TRX-2 decodes simplex perfectly in the Tune mode? FYI, my TRX-1 decodes nothing.
I wonder if a firmware update could fix this, and if Whistler has any plans for it.
Thanks for your help Ubbe
The simplex portables can be 20 feet away or in a building 2,000 feet away and the TRX-1, when in the analog mode, hears the staccato TDMA transmissions from the simplex portables. This indicates that there is no overload or interference.What's the distance from your new TRX-1 and the "nearby" simplex transmitting radio? It could be a case of overloading the TRX-1 front end.
Do you need to open the squelch, set it to zero, to be able to hear the audio?The staccato TDMA signal can be heard if the scanner is in the analog mode.
