The other day I was working my Fusion repeater with my FT70D. Since I was “DX” I had the HT on high power. Although it looked like I was getting into the repeater just fine, I couldn’t enter the WiRES-X control mode. However when I switched to low power I WAS able to control the repeater. What gives? Why could I control the repeater (node) on high power, but not on low power? Back at the house where my repeater Read more…

Photos show the waveform capture from an FT5 during a MNWis net. Note that they are not symmetrical around zero. The 2nd image has more detail and you can see that the waveforms are not symmetrical. The clipping sound is heard when the audio level hits the limits even though it is still not at 100%. Odd. Hits: 42
I don’t know why Yaesu doesn’t make this public, but they don’t. You can download version 1.44 of the IMRS LAN firmware. This solves some problems with LAN connections constantly dropping. Hits: 98
During the Monday Night Fusion Technical Net, a comment was made that it was possible to use an FT5D to receive C4FM on 29.250. This started a conversation about other HT’s as well. Thanks to W4IOD, AD0MI, N0PXT, and N0OQL, we now have the definitive answer for most of the Yaesu Fusion radios. Background Using 29.250 for C4FM has become popular as 10 meter conditions have improved significantly. The Yaesu FT-991(A) is the only radio that is capable of Tx Read more…
This post addresses a WiRES-X node that constantly leaves and rejoins a room. This type of problem is almost always the result of a networking issue. When certain networking problem occur the HRI-200 software will wack out (a technical term). 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 Read more…
Some thoughts about Fusion, digital modes, and the future. Fusion uses the lower layers of the P-25 architecture. Modulation, transport, framing, etc. The primary differences revolve around what’s in the packet. For example: The use of call signs instead of unit IDs. So Fusion shares most of P-25. FWIW, Fusion is also very similar to DMR. The primary difference is that it doesn’t use TDMA – jamming two separate channels into the space of one. P-25, DMR, NXDN(Kenwood), IDAS (Icom), Read more…
DG-ID is like a CTCSS tone, but for digital. It filters out signals with different DGID’s as well as having the ability to do split DG-ID’s (like split CTCSS). DG-ID can be in a state of Rx & TX (DG-ID), Rx Only, Tx Only, and Split Rx & Tx (different DG-ID). DG-ID servers as a means of selective signaling for access to a repeater or for a WiRES-X node. For the repeater it has a couple of different applications (IMRS Read more…
