Installing, configuring, and operation a Fusion repeater.


Many people have reported Fusion repeater lock-ups that required the repeater to be shut down (power removed) and rebooted. I’ve had repeater lock happen as well with an HRI-200 directly connected to the DR2X. In this particular case I believe the event was triggered by sending a number of commands from the radio (such as the GM mode) which resulted in a race condition within the firmware. I have previously observed that invalid data (I.e., with a lot of bit Read more…

The DR repeaters are calibrated in the middle of the band. For UHF that is 440.000 MHz. You may want to check the power output at that frequency as you are operating right at the band edge. While you’re at it, measure the Tx current. At the lower power output the current should be lower, otherwise it could indicate a problem. Under no circumstances should the Tx current be above 10 amps (I recommend a 10 amp fuse in the Read more…
