Transceiver is intended to concerned work with PC and sound card. This device opens up absolutely new opportunities for the users, because it’s possible now, not only to hear the signals from the stations, but also to see them on a screen of the SDR-program. It is also possible to record the signal from the air and to reproduce it into the air back. Small number of the components reduces the level of noise floor.
SunSDR is a PC device, which in connection with SDR program represents the full value transceiver. Anodic robust aluminum case doesn’t conduct electricity, which prevents from possible shorts if bared wire hits the case. This device has a built-in protection from polarity reversal. Mounted Jack 6,3 mm connectors possess qualitative electric contact, a factor which makes lower quadrature disbalance. High-speed USB 2.0 interface is used for transceiver’s control.
SunSDR electronic part is executed on one two-layer PCB. Due to this engineering solution the device has certain advantages: greater reliability, small enclosure dimensions and weight. The amount of digital lines on a PCB were reduced because of mounting on the card CPLD. Therefore it makes lower the level of noise pickups from digital chains (because now they are placed inside CPLD crystal). It should be also noted a low level of the carrier frequency transmitter (lower than -55 dB), reached by right component layout of mixer and transmitting tract topology. Band LPFs (low-pass filter) are executed on a ceramic chip coils. Using such technology allows to make lower the level of intermodulation distortion transceiving tract and makes higher a receiving dynamic range.
Receiver has 5 gain levels, which are switched from the program ExpertSDR. Each gain level defines receiver’s sensitivity. Receiver’s measurements with the soundcard M-AUDIO – Audiophile 192 are shown in tables 2 and 3.

Good evening, I’m pp2zm Roxanne by Goiânia, Goiás, Brazil, I am intereçado in buying the sunSDR 30w all band ???, it has all the amateur bands? you guys do not have to 100w? because 30 w hard excite a valved linear ok, the accompanying sdr box? USB cables? mic? phone? power supply? has 220 voltage? or 13.8? amperage source? It comes well packaged? You do not have danger on the journey freight for Brazil? can put note below the price for me to pay less taxes when entering the custom house of Brazil. product can be priced more than half the price, would put price well below invoice ok, posivel? rates here in Brazil spends 60% above $ 50 ok, I’m an amateur poor lol please what price with shipping to Brazil? where and how should I pay? guarantees? bank deposit or other means paypal? I have only visa card or deposit money, sunSDR works with any program other than the expert sdr, power sdr or others? thank you, agradesso exclarecimentos. here in Brazil what one knows more is flexradio, I saw the announcement of you and I intereçado in Russian technology. 73 sorry ingles errors, I’m using google translator, I do not speak English PP2ZM IN QRZ.COM HENRY MY NAME.
