It seems likely to eventually become available to many other countries.ĥ.287200MHz is used for transmit by countries that have not yet been allocated the new IARU frequencies, South Africa is the most commonly active on this frequency. There are two main Dial Frequencies in use, the original 5.287200MHz and the new 5.364700MHz.ĥ.364700MHz is within the recently agreed IARU segment and is used for transmitting by most European countries that have an allocation. Sometimes at startup or restart one of the USB sound devices does not initialise properly and has to be unplugged to reset it.
Other devices I use are the USB Sound Blaster X-Fi the 4 channel (2 stereo pairs) Maya 44 USBĪlmost any USB sound device will work, the generic drivers will enable 16 bit 48KHz.
On the other hand I find that the old USB Sound Blaster Live! SB0490 0Hz is supported as are other Creative "end of life" devices. This computer was sold new about a year ago and I have troubles with the built-in sound. Something similar may possibly happen to others. Īfter 5 months the on-board sound now works properly again.
Looking again today I found certified drivers for Windows 10 October 2020 Update (20H2) release date. I tried Windows update, Dell and Realtek, found no compatible driver, tried a few and ended up with no output. I rolled back but eventually had to take the update with the same result. The front socket did work but was very inconvenient as it is difficult to stop the cable obstructing the DVD drive. The facility to select the output had gone.
The speaker output at the back of the PC stopped working. The 10 October 2020 Windows 10 update caused a problem with my on-board Realtek. Spectrum Laboratory and WSJT-X must use a different system because they do not require reconfiguration. I have not found any other soundcard RXTX program for Windows 10 that will run multiple Softrocks. It is often best to close HDSDR and the WSJT-X instances and restart. When a device is disconnected Windows re-orders the devices and HDSDR loses connection and has to be reconfigured. The way HDSDR v2.80 selects sound devices made the sound device disconnection more frustrating. (SupaGeek PCI-E to Type C (1), Type A (4) USB 3.0 5-Port PCI Express Expansion Card, Capable of Expanding + 2 USB 3.0 Ports with Internal 19-Pin Connector) The on-board USB3 was not coping with my reqirements. I did not overcome this until I eventually fitted a PCIe USB3 card and used that for my sound devices. I was plagued by sound device disconnections, sometimes when plugging other USB devices, sometimes for no aparrent reason. All USB power saving has to be turned off.įundamentally this worked well but not for long. Permanently disabling HDMI or other audio devices in "Sound Properties" is a way of avoiding this. This includes HDMI audio which is stopped if the screen saver is allowed to operate. It was necessary to make sure that none of the sound devices on the computer was turned off by Windows for any reason. I also use other receivers usually running 5 instances of WSJT-X. To keep my Softrock RXTXs working I had to use multiple instances of HDSDR and virtual audio cables. I could not find suitable internal sound devices so had to accept that USB devices would have to be used. I wanted something that would replace that and run the latest wideband SDRs so purchased a Dell XPS 8930 with a Core I7-9700 and Nvidia GeForce RTX 2060. This had the equivalent of about 10 stereo audio systems including a M-Audio 1010 and 2 Delta 44s. In August 2020 I decided to finally update from my XP SDR computer.
