I decided to stop trying to use two different computers (one Win10 PC for amateur radio and one Mac Mini) more or less at the same time, switching back and forth keyboard and screen. So I upgraded my Parallels to version 15 (at reduced price..), installed Win10 on the Mac Mini and started to transfer the different amateur radio programs to the new Win10 virtual machine. Running WSJT-X on Win10 in Parallels works, but I noticed dropouts on transmit. No issues on receive, only transmit. Audio is all about timing, and generating the WSJT-X audio requires proper timing, something that a virtual machine will struggleRead More →

I have both the IC-9700 and IC-7300 Icom transceiver connected to my Win10 PC. Looking at device manager or your amateur radio software setup, it would be nice to know which is which. The serial ports of these Icom radios have model and serial number embedded in the “serial” field of the USB device properties. On Windows, this information is used to keep the device assigned to the same COM port all the time. Unfortunately, the audio devices are all called “<some number>- USB Audio CODEC”. So “2- USB Audio CODEC” references my IC-7300 and “3- USB Audio CODEC” my IC-9700. This is not somethingRead More →

“Verbannen” is a dutch verb and means “to ban”. As in Napoleon being send to St. Helena. To ban in the context of gaming is being blocked out. With the rise of Facebook and the like, you can even be locked out of groups and communities. But to ban also has a meaning in context of IT security. For example, your account might get blocked after too many failed password attempts. This requires processes to unlock and restore access. One way to avoid this, is to automatically restore access after a certain amount of time. Napoleon was banned until his dead, 6 years later… ItRead More →

Icom’s new IC-9700 can receive two bands at the same time. In DV mode, it can decode two digital signals at the same time, something even the IC-5100 cannot do. Since it has a stereo USB audio interface build in, it’s logical to expect the IC-9700 to output main and sub band audio at the same time over USB as well. Some sources on the Internet mention that only main band audio is output via USB. Given all the “at the same time” features of the IC-9700, I resisted to believe this to be true. So … let’s check the schematics first. Not only inRead More →
