Works with sound cards for example USB and has a band 96 kHz for a sound overview 96 kHz and 192 to 192 kHz audio. If 2 48000 Hz too, but the review/sample 48kHz. Modern laptops have good built-in sound card – 96 kHz review – check in the properties of the audio and if there is 2 96000 Hz it OK. Kit for 20m 5W SDR transceiver for CW-SSB-Digital (JT65-SIM31-Opera-WSPR-PSK-RTTY) he have set of 2 quartz on SSB and for CW-Digital (JT65-SIM31-Opera-WSPR-PSK-RTTY) with sample 96kHz sound card. SOFTWARE – FOR WINDOWS – GSDR-KGKSDR-ROCKY, ALSO POSSIBLY FOR LINUX, FOR MAC OSX. Image rejection greater than 60 dB at a program correction. The suppressed carrier transmission is more than 40 dB (45 60 dB) and depends on the specific instance 74HC4051, as well as the quality settings. Dynamic range more than 90 dB intermodulation or rather there was nothing to measure. When the TX mode is easily 5W and more -TESTED with GSDR-KGKSDR-ROCKY. FOR TX will need to add com port and sund card (speaker) output to connect with OUT on the PCB Board. If you only use it as a receiver it is enough to apply power and connect the input IN the on- PCB Board to sound card – stereo -Line IN. For more bands or wide range also you can use VFO or external synthesizer frequency, the signal from which you want to apply for 1st 74HC04 output through the coupling capacitor 10 nF. THE THIS KIT IS ASSEMBLED AND TESTED ON THE ATTACHED CIRCUIT BOARD-ALL WORKING AND ALL WITHOUT ERROR. Quality printed circuit Board on FR4 with mask and mark components. When you build without errors begins to work immediately. The design was repeated many times and worked well. THIS IS KIT SDR TRX - Pout = 5W (final two IRF510, driver KT646 -> 2N4921). NEW NICE PCB WITH MARK ALL COMPONENTS and NOMINALS! PHOTO 4 – example assembled kit. > add Si570 k5bcq/Kit with digital readout and encoder+usb sound card and ready! Ecommendations for 40m – BPF L1-L2 inductance 2 µh -quartz 7050 -the turns on the coils and C to increase in 2 times. A list of resistors and capacitors included with the order. NO of resistors and capacitors is not deficit and they are easy to find – In order included schematic with all nominals + it have print directly on PCB board. Kit consists HIGH quality PCB board, all connectors, BNC ANT, rs232, 2 Quarz 14058 +14200 kHz, all the relays, the RX BPF 20m ready 2pcs, 4 pcs chokes 10 + 100 uH, torroids for T1 and LPF, all the diodes, transistors and IC. In software GSDR perfectly fulfills wbir with the system of suppression of mirror channel.
Believe it or not, but the reception is better than many expensive devices including SDR – compared to Opera and wspr with. As an example, immediately after the Assembly of the connection 3400 KM in JT9 mode with EA5GIN (JT9 requires great precision and stability).
KIT TESTED AND WORK SUPERFB on OPERA-WSPR (no drift)-JT9-JT65-PSK AND SO ON.
