LIMIT QTY ON STOCK NOW. KIT TESTED AND WORK SUPERFB on OPERA-WSPR (no drift)-JT9-JT65-PSK AND SO ON. As an example, immediately after the Assembly of the connection 3400 KM in JT9 mode with EA5GIN (JT9 requires great precision and stability). Believe it or not , but the reception is better than many expensive devices including SDR – compared to Opera and wspr with. In software GSDR perfectly fulfills wbir with the system of suppression of mirror channel. 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. 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. A list of resistors and capacitors included with the order. YOU CAN DO STANDALONE 20m SDR. >> 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. PLEASE READ MANUAL >>> MANUAL. THE THIS KIT TESTED ALL WITHOUT ERROR. NEW NICE PCB WITH MARK ALL COMPONENTS and NOMINALS! PHOTO 4 – example assembled kit. THIS IS KIT SDR TRX — Pout = 5W (final two IRF510 , driver KT646 -> 2N4921). The design was repeated many times and worked well. When you build without errors begins to work immediately. Quality printed circuit Board on FR4 with mask and mark components. THE THIS KIT IS ASSEMBLED AND TESTED ON THE ATTACHED CIRCUIT BOARD-ALL WORKING AND ALL WITHOUT ERROR. 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. FOR KITS VERY VERY USEFUL THIS ONE –. 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 TX will need to add com port and sund card (speaker) output to connect with OUT on the PCB Board. The sensitivity is less 1 uV (microV). When the TX mode is easily 5W and more -TESTED with GSDR-KGKSDR-ROCKY. Dynamic range more than 90 dB intermodulation or rather there was nothing to measure. 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. Image rejection greater than 60 dB at a program correction. Current draw in RX mode less 90mA. Output power of about 5 watts. SOFTWARE – FOR WINDOWS – GSDR-KGKSDR-ROCKY , ALSO POSSIBLY FOR LINUX, FOR MAC OSX. 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. 14058 >> 14010 to 14096 Khz. 14200 >> 14152 to 14248 Khz. 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. If 2 48000 Hz too, but the review/sample 48kHz. 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. Especially now a lot of good pci and external USB sound cards Asus Xonar u5 u7 , M-Audio, Creative, ESI , UGM96. This set to 20m – turning on the switch and commutating 2-3 quartz can cover the entire range 20m. 20m Most popular and good for digital. USB mode (kHz) — 14062 – Opera 14067 -SIM31 14070 -PSK31. In addition, since the output of the transceiver of signal IQ y ou can in a wide band decode WSPR-CW(CWSkimmer)-JT65 (MAP65) The KIT is very easy. All large DIP elements all on the same. ALL ON ONE PCB. Including PTT via a COM port (USB-COM adapter will work). To work on this transceiver very nice and comfortable. All control a computer mouse. See the whole range in the band of 96 kHz , and a simple indication or “drag” the filter program is instantly rebuilt on the desired station. Very quickly and clearly. After working on this transceiver , operating on normal something is missing the visual information about the situation on the range.
