DMR with the CS-580

Programming your DMR HT is very straight forward – all that has to be done is presetting a memory bank for the Hotspot, and programming each Talk Group you’ll likely use in a separate channel. Set the TX/RX to the same frequency in the memory channels, and vary each one for each talk group. With the hotspot, while you can program an “unlink” command, it is not necessary unless you plan on just utilizing as a simplex repeater, every time you key up a new talk group, the Hotspot unlinks from the previous group, and links to the new one automatically. Below are step by step instructions for programming the CS-580 (BFXD HT), your mileage may vary as I only have DMR experience with this radio, and I’m unaware of how the software for the TYT MD-380, or Hytera radio’s works in comparison.

Save, and Write the Data to your Radio… We just have one more step! In a lot of cases the DMR radios that people use are Chinese radios that are cheaper, and not necessarily as clean on the spectrum.. So to accommodate this, we’re going to go into our expert settings, and open up the TX/RX sensitivity of Pi-Star.. This is done by clicking the Expert option at the top of the Admin menu.. You’ll be brought to the screen below:

You’ll be brought to another screen where the second orange line down says “Modem” – this is where we configure the offset sensitivity. We’re going to open that number up from 0 on both to -475 for both TX and RX as you see below

All other data can remain as is. Apply your changes, and reboot, and you’re up and on the air with DMR!
