More resilient to large signal levels and only slightly less sensitive. To perform very well if some external gain is added.Īre in the USD 230-250 range, not much more than the SDRPlay RSPdx but a lot The Perseus + Jaguar combo is still my choice for MW DX-ing, the RX888 appears Originally, the names of these APIs all began with Direct, such as Direct3D, DirectDraw, DirectMusic, DirectPlay.
If you want to control the PC via remote control, my only advice is: Don't restart the PC. Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. This may not matter too much if you always sit in front of the PC. You need to disconnect and reconnect the USB cable for the PC to recognize the devices.
Since the Cypress driver was already installedįor the RX666, the RX888 connected right away.Īlas, to my disappointment both the RX666 and RX888 suffer from a serious flaw: After a PC reboot, the devices will not restart. Require a USB 3.0 port on the PC, and of course the wider sampling rates, the Supports the RX666 and RX888 and offers a 1-MHz sampling rate in addition. In addition, there is support for 64 MHz sampling rate. Sample rates when using the dlls developed for HDSDR are 2, 4, 8, 16 and 32 MHz. You do, you can always reduce RF gain by 10 or 20 dB. Signal level MW band, fed from a beverage antenna, and noted no overloading. A 16-dB preamp from DX-Engineering increased sensitivity by 13-14ĭB, which is a massive improvement. Part though, is that the ADC is quite forgiving if you decide to use externalĪmplification. This isĥ-6 dB worse than the Perseus, and 10-12 dB worse than the Airspy HF+. KHz (AM mode, 6 kHz bandwidth, a 400 Hz signal with 30 % modulation). I have used the assets from the actual game for the menu system. Although the RX888 has an LNAīuilt-in, sensitivity figures are still in the lower part of the list, 3-4 dBīetter than the RX666. This is a demo which I have created in DirectX, I created it by starting off with Frank Lunas framework, I have tried to re-create the game de Blob. Theĭownside, as with the RX666 is sensitivity. In that respect, the RX888 performs very well indeed, even if the only filter is a 64 MHz low pass filter. Heat dissipation panels make up three sides and of course adds to theĪDC (Analog Devices LTC2208 in this case) is always better than 14-bit orġ2-bit ADCs, especially when negotiating the huge signal levels on the MW band. It measures 72 x 83 x 43 mm (excludingĪntenna connectors) and weighs in at 160 grams – less than half that of the
