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…


I use VyprVPN from GoldenFrog. It is necessary to turn of NAT for your account. That means that each VPN connection is a raw connection straight to the Internet. YOU HAVE NO PROTECTION OTHER THAN WHAT YOU PROVIDE!!! (The same company will rent you a VPN that you can host on your own cloud provider where you can control port forwarding – but I suspect this is well beyond most folks.)   I’ve been using this solution for over a Read more…


If you are experiencing low or no power output…..   1. Replacing a blown final does not necessarily fix the problem that caused the blown final. Never replace a blown final in anything where you haven’t gone through and figured out if there was a reason the final blew. These are very rugged transistors that should last a very long time.   2. Some failures are related to heat, most are not. The DR repeaters have excellent cooling. Unless the 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…


What’s up with the FT-70 battery indicator? Why does it seem like the battery doesn’t last very log? The FT-70 doesn’t actually know the state of charge of the battery. It only knows the voltage – which can be misleading while the battery is being charged. The Battery Management Unit within the battery pack is responsible for managing the charging and discharging of the battery. While computers and smart phones generally use the BMU to display state of charge, I’ve Read more…


What’s the difference between using an HRI-200 and directly connecting to the radio? 1. It is the only option for connecting a repeater to WiRES-X.2. It uses UDP communications sent directly to the Room. So network communications are very efficient.PDN uses TCP instead of UDP. (Why use UDP? UDP is simple. If anything gets lost, it is dropped. Good for real-time communications. If a packet is missed with TCP, it will keep retrying up to a limit which is not Read more…


When a WiRES-X node keeps going online then offline, this type of problem is almost always the result of a networking issue. A networking problem will occur and will wack out the HRI-200 software. Once the software has been wacked out, it will continue to cycle in and out of whatever room it is connected to. Restarting the WiRES-X software usually solves the problem. Router problems:1. Turn off UPnP. It should never be used!!!!!!2. Turn off all quality of service Read more…


If you’re having problems with USB problems when using WiRES-X with or without other programs, read on. The WiRES-X software is pretty good at identifying the HRI-200 vs. connecting directly to the radio. Windows, however, is very bad at managing USB ports. The WiRES-X software makes two USB connections: One as a virtual COM port and the other as a sound device. Windows is also very bad at managing sound devices. Virtual COM ports can be identified by the port Read more…
