A hotspot that can help you to access the talk groups when you don't have a DMR repeater nearby. Normally hotspots are capable of multiple modes as well, such as D-Star, P25, DMR+, YSF and NXDN… but we are only going to talk about DMR here.
1. If you only have ONE DMR hotspot, configure it using your own DMR callsign and ID.
2. Be mindful of what Talk Group you are using. This is especially important if you are chatting with a friend who is also on a hotspot. It might be best to choose a TAC channel for that.
3. Remember that hotspots are generally reliant upon good WiFi and Wlan Interent. If you take your hotspot go outside, your phope wifi is very important.
4. Most important of all, check your BER in the hotspot dashboard. If it’s too high, check your RXOffset and TXOffset. You might need to adjust it higher or lower to get your BER down around 0.2% or less. This is VERY important to achieve reliable usage of your hotspot.
How to adjust the RX/TX offset, please read this blog: https://www.ailunce.com/blog/How-to-set-Rx-Tx-Offset
1. First makes sure your DMR hotspot configuration is finished.
2. Choose a DMR Radio. For example some popular DMR Radios. #Retevis RT3S, #Ailunce HD1.
3. Here take Retevis RT3S as a example.
--Open RT3S software, Find General Setting, Write your callsign and DMR ID.
-- Create some talkgroups which you want to monitor. I think TG91 should be the most active talkgtoup on Brandmeister. You may meet hams from different countries.
---Create channels. Normally we can create a private echo test channel to test if the radio works well with the hotspot.
4. The very important step. Dont forget to add the channles into a zone. or you will see unprogrammed on the radio screen.
All above steps are finished, you can QSO with any hams on the air.
