Q&A



What type of network redundancies are in place for DMR connectivity to the world?

While are cannot fix every issue out of our control we can do our best to keep connectivity flowing for the users. Our current network redundancies in place include full BGP Routing and Peering for shortest route path as well as all N2CID repeaters being load balanced against our internal master servers which are also load balanced against all (4) of the BrandMeiser US Master Servers. If any of the BM master servers go down or become unavailable for any reason our systems will automatically connect to the next available master server with the least latency and continue to route traffic over our Clusters and Talk Groups it as if nothing ever happened.

Some people have HOT Mic’s (Really LOUD) or are really low and hard to hear on DMR. What can I do on my end to fix that?

Unfortunately there are so many brands of DMR radios out there its hard to have an actual standard. I personally use the 25% rule which is; your mic gain should be set so that most people can hear you perfectly with their volume knob set to 25% audio. This leaves room to lower the volume if needed but also allows a 75% increase of audio if you are somewhere really noisy say in a vehicle or crowd. This 25% rule seems to work quite well among the users on the system. Don’t be afraid to adjust your audio gain and get on the system and ask how it sounds. We’re all here to help and enjoy the hobby together!

What is linking or Clustering and how does it effect my Hot-Spot or Repeater?

Linking or Clustering is the ability to link a static Talk Group among many Hot-Spots and Repeaters in the area which help to extend the communication coverage of that Talk Group or (TG) for local Hams. Once you are linked in and you use your Dual-Radio Hot-Spot from anywhere in the world on TG:310441 you will still be connected to all the local repeaters in the area as if you never left. As an example lets say you travel to Florida for vacation and you have your Hot-Spot connected via your Hotel or Cellular Phone. Now you key up on TG:310441 and magically through the internet you are talking over the repeaters in Buffalo back to your friends and family locally!. The main N2CID Repeaters also support TMS Texting, Telemetry, GPS, GNSS Tracking (including Altitude, Lat, Long, Speed and Direction), APRS Tracking and Messaging, ARS and LRRP as a standard. Linking actual repeaters together helps with building the TG coverage map as well.

Why did you choose a BrandMeister only approach to Repeater linking?

To start I took a poll on our site over a period of three months and explained this ability and options and asked current users to vote on whether they would like these data features which are only available with using BrandMeister or would they prefer Voice only service on other networks. The vote was 28 to 1 for BM at the end of the poll and enabling the ability for them to use these extended features they were interested in so we took that approach.

Brandmeister is the only ham friendly group that allows full extended data routing across their network and endpoints versus just Voice. This gives us the ability to utilize linked routing of DMR data between repeater sites to include DMR IPv4/IPv6 encapsulated packet routing as well as TMS Texting, Telemetry, GPS, GNSS Tracking and messaging via APRS as mentioned above. Without this ability we would have none of those extra features for you as well as more in the future. We would be restricted to a Voice only service. We also back haul any traffic we cannot send over DMR directly between sites via an IPv6 mesh management tunnel.

How to link your DMR repeater or Hot-Spot to the N2CID DMR Repeater network.

As of 1/1/19 you can now reach the N2CID Network on TG 310441 from any Repeater or Hotspot around the world.
