Driver Install. The SiLabs CP210x USB to UART (Serial Port) bridge chip inside the IC-7300 needs a driver. This driver is automatically installed when on Win8.1 or Win10. No need to install the Icom supplied driver. The Audio CODEC inside the IC-7300 does not requires a separate driver install. It is so-called class-compliant. There is nothing Icom specific in the USB part of the IC-7300. Actually, when you analyze the schematics, you’ll see that the build-in interface does not differ from most external interfaces: the decoded analog audio is actually converted to digital again in the USB Audio CODEC. From a practical point of view,Read More →

For powering an USB device in your car, you need a 12V car adapter. Such an adapter plugs into the cigarette lighter socket and provides an USB socket. You also have to specify the current, since USB by default provides 0,5A but for charging purposes can deliver up to 2,1A. Then you have a clear functional description. I have an Anker adapter and one from Huawei which came with my Huawei E8278 LTE stick. Both adapters deliver sufficient current, so from a functional point of view, both adapters are equal. Unfortunately one works fine, the other one not. Here engineering comes into play. Your car does notRead More →

“Using a remote desktop program from Google”: that sounds unsafe. But why should I trust for example TeamViewer more. At least Google Remote Desktop is much more streamlined; I don’t need those “Team” functionalities. Both TeamViewer and Google Remote Desktop use UDP hole punching in order to traverse your NAT in the “wrong” direction. That’s actually proving the statement that a NAT router (such as the one that connects your home network to the internet) is not a firewall. Therefor my remote machine sleeps, and I have to wake her by logging in with ssh (using certificates of course) which triggers the bonjour sleep-proxy on myRead More →

OSX makes me happy. A professional desktop with Unix under the hood. Too bad Linux never made it to that level and is still stuck on X11. Unfortunately, our current IT world requires you to be able to run Windows applications. Be it your Tax program, or your favorite Amateur Radio logbook. You can use Wine, and many applications run under Wine. But what does that mean, run under Wine? Does everything work? That requires you to test every functionality of an application. I thought that when the main stuff works, the rest also works. Wrong. My favorite logbook program works 99% under Wine, onlyRead More →
