![]() Repeaters on the Brandmeister network support each of the more than 1,500 Brandmeister talk groups on either time slot. Dynamic talk groups automatically deactivate after a certain time without local activity (typically 15 minutes). Dynamic talk groups are activated on demand when a local user transmits on that talk group. The Crossroads network hoped to resolve the issue soon. ![]() ![]() 19, 2022 (and perhaps earlier), the Parrot talkgroup (9998) is unavailable on any Crossroads repeater, due to a network issue. Generally analog radio are much more forgiving of incorrect use of microphone gain and usage than digital radio as the dynamic range of the audio are very limited in most digital radio systems that requires a perfectly balanced audio level from a microphones compressor/limiter circuit.As of Nov. I've heard DMR transmissions that sounds real good but the exact same people could later sound awful, so DMR are probably more demanding of the correct microphone technique. Both hardware and software are probably then more advanced in Tetra equipment. But the equipment also costs 10 times more. All good compressors have some sort of bass cut and/or high end increase to compensate for that problem.Īlso if the data bits are lost during the air transmission it will create errors in the data and will also reduce the signal to a low defined audio signal without any high end and syllables will be lost.ĭMR mostly uses 2 timeslots at a 12,5KHz bandwidth and Tetra uses 4 timeslots at a 25KHz bandwidth but the audio quality in Tetra are much better. If you speak too close to a microphone or use compression you loose high end and add low end frequencies in the voice band. Of all the DMR repeaters near me, I only hear traffic about twice a week. Around here DMR was very popular a few years ago. Additionally, the skillset of the installers is not the same.Īnother way to fix it is for everyone to avoid using inexpensive DMR radios, or avoid talking to someone until they purchase a better radio. All DMR repeaters are not the same, nor is the ancillary equipment installed with it. The settings that can be changed would be to use a different digital mode that sounds better to you. Yes, digital modes, DMR being one of them, typically use less bandwidth for efficiency and or to also pass data with the audio.Ģ. It costs around $1000, or was it $3000, I forget.ġ. The best sounding DMR radio I have ever heard is a Kenwood 5300 series. Additionally, some inexpensive DMR radios have poor transmit audio which makes it more difficult to understand. Commercial, Professional Radio and Personal RadioĦ.25 kHz of bandwidth does not convey the human voice as well as analog with more bandwidth.We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. The benefit is you do not need multiple versions for each radio (unlike Motorola). The conventional package is more reasonable though is still several hundred dollars. The trunked package is in upwards of $2,500. One package is for conventional programming and the other for trunked programming. Often the Kenwood software is less than $100 so don't be a cheapskate just purchase it.įor M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. Typically each series or individual radio requires its own software package. Please use Google or some other search engine to find a dealer that sells the software. The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). To obtain Motorola software see the Sticky in the Motorola forum.
