Silent Key
Using a Baofeng DM-5R Plus, programmed with the supplied software application: CPS_5R. (Chirp does not support this radio???..yet.)
Analog vhf-highband and uhf stuff is fine.
But, not having any amateur DMR repeaters anywhere within a 75 mile range to listen to, I decided to use the radio to listen to a few area public safety agencies who have migrated to DMR (Tier-2), to try and get my feet wet in this format.
-------------------------------
Before anyone comments, YES I know the DM-5R Plus does not support proper Tier-2 operation and cannot access independently TS-2, and therefore has been banned on Amateur repeaters. Not an issue here, as I am only trying to listen to anything I can.
-------------------------------
One of my local PD?s is on 461.17500 MHz, Color Code 5, Time Slot 1, Talkgroup 10001. (see: Staunton City, Virginia (VA) Scanner Frequencies and Radio Frequency Reference )
Using the programming application (CP_5R Version 1.0) from Baofeng, I create a digital channel, program the receive frequency (461.17500), and as a precaution I program the transmit frequency for something in the 70cm amateur band, and go through their convoluted process to link in the talk GROUP LIST to this channel. (See attached images in PDF)
On an analog FM receiver, I hear digital noise on the frequency.
On the DM-5R Plus radio, I see a green receive indication light, and a signal on the little bar graph signal strength indicator, but no audio is heard in the speaker.
What am I doing wrong ???
I may have worked for 34 years in two-way radio as an Installer, Technician, and lastly as a P-25 System Engineer. But this is killing me !
