nejnovější softwarově definovaný transceiver s rozsahem 9 kHz - 65 MHz a 95-148 MHz

Na rozdíl od jiných SDR, které se standardně připojují k PC pomocí USB kabelu, zde komunikaci zajišťuje síťový ethernet kabel.

To má výhodu v mnohem větší rychlosti přenosu mezi přijímačem a PC, umožňuje použití delších kabelů a integraci SDR do místní sítě a remote provoz.

SDR se dodávaným kabelem připojí buď přímo k PC nebo do routeru.


Frekvenční rozsah 9 kHz – 65MHz (RX), všechna am. pásma KV/6m (TX)
Frekvenční rozsah VHF 95-148 MHz (RX), 144-146 MHz (TX)
citlivost 0,07 uV
Výkon TX 100 W (HF), 50W (50 MHz), 8 W (VHF)
Blocking Dynamic Range 129 dB (HF), >114 dB (VHF)
RF ADC clock freq. 160 MHz
RF DAC clock freq. 640 MHz
RF DAC resolution 14 bit
napájecí napětí 15V (12 až 16 V)

stabilita místního oscilátoru +/-0,5ppm
built-in audio codec resolution 24 bit


The SunSDR2 DX transceiver based on the well-known SunSDR2 PRO transceiver with several hardware improvements. It is a 100W-HF; 80W-6M; 8W-2M transceiver, very compact, has active cooling and
improved supply system, meaning it’s perfectly suited for DXpeditions. Also, we've added a separate connector for an external ATU, thus SunSDR2 DX has all the functionality you got used to in our radios and even more.
Improved hardware along with the ExpertSDR2 software makes this high-performance SDR transceiver the perfect base station. The evident choice for a true contester!
Hardware improvements of Gen5 (late 2022) in comparison to Gen1 (November 2019):

Redesigned heatsink, with thinner and more frequent gills for higher effectiveness
Improved temperature sensor placement for more accurate temperature readings
Improved TX IMD3 up to ~37 dB across all HF bands, with 100W output power
6M output power have been increased up to 80W
Improved SDR PCB protection from cross-talks. Improved protection for the supply chain
Added ferrite bead on the flex-cable connecting PA and SDR PCBs, for more stable operation with external ATU
Added filtering of the headphones' connector
Slight improvement of the RX path
Redesigned TX filter of the DAC chip, which provides better linearity of the TX signal
Redesigned band pass filter on the PA input, which improves linearity of PA operation
Improved structure of 160, 6M TX filters
RX/TX switching node on PCB is more resilient now

Hardware improvements in comparison to SunSDR2 PRO:

HPF for VHF (100 MHz) to eliminate strong out-of-band stations coming from HF
LPF for HF (70 MHz) to eliminate strong out-of-band stations coming from VHF
New VHF LNA chip - PGA103+
New high-performance built-in stereo audio codec 24-bit with 114 dB dynamic range (CS4272)
Improved supply system, which leads to less heating and less power consumption
Active cooling
Antenna switch supports Predistortion without external devices
Improved topology of SDR PCB
