RFinder B1 to the Rescue

 
Given my RFinder B1 – I often find myself as the main rescue tech who is working comms. This is due to this radios ability to work on any comms mechanism (cellular / DMR / VHF / UHF or DMRoIP) – as such I have the means to always be able to find a way to radio to command.
This photo was for a rescue mission at 5k feet in eastern Oregon. Air temp: 20 degrees Fahrenheit, and Windy… notice my antenna bending. The only way up this scree-hill was a steep, slow, brutal climb from 1k feet. No repeaters in range, all comms were Simplex only. However, at one point I did need to ride the cellular signal and use DMRoiP… as we were too far over a ridge in a “shadow” for SIMPLEX DMR from the base station… but I could just barely hit a cell tower and get strong enough LTE to bond to Brandmeister DMR!
Well done RFinder team. This is a great tool.

Setup 4G with AT&T on the RFinder

by Bob Greenberg

Call 866.344.6217 ATT 2nd level support. Give them your phone number of the device. Tell them the system is incorrectly showing the device as 3G. Ask them to make it look like a Galaxy 8S. If the first person cannot figure it out hang up and call back. They will make the adjustment. I just came back from Africa and when I landed the B1 once again came up as 3G I had to call them to reset it. The other option is to get a mintmobile.com SIM and port the number to them or TMobile. They like all the other carriers worldwide will gladly support your device as the 4G device it is. You will save money on TMobile or Mintmobile.com anyway. They have something new ask them to put a monitor on it to stop it from happening….they just did that for me about 5 minutes ago.
