Review Summary For : RX9CIM SDR Original Russian Software
Reviews: 1MSRP: 18500 Rubles
Description:
Key Features: 1. the radio is built according to the SDR principle - the functionality is determined by onboard software 2. frequency range - from 50 kHz to 250 MHz and from 400 MHz to 2 GHz 3. types of analog modulations: AM, SSB, NFM, WFM (RDS info in FW1.0b) ; Morse Code Decoder 4. functionality: variable filter width, adaptive squelch,threshold squelch, Noise Blanker, AGC, equalizer; The cheap but functional msi001 was used to achieve this. 6. The powerful stm32h743 Microprocessor with a clock frequency of 480 MHz was used for the processing 7. 3.5-inch display with a capacitive touchscreen 8. built-in UHF pre-amp 9. controls - 2 encoders with push-in buttons and a touchscreen; 10. power supply from built-in battery and USB, charging from USB. The capacity of the built-in battery is at least 1500mA / h. 11. consumption - 300mA when listening to headphones; 12. reception on built-in telescopic or external antennas. For improved HF reception on the telescopic antenna an add-on board is available at an additional fee The board contains: 4 filters: LPF 500kHz, bandpass filter 500-1500kHz, bandpass filter 1500-4500 kHz, HPF 4500 kHz An attenuator, adjustable in the range of 0-30dB with a step of 1dB A source repeater with switching elements The board is built to fit the standard receiver design. 13. USB connection to a computer with the ability to transfer CAT, IQ and audio. 14. 160 kHz span with scalability; 15.sensitivity - 0.3 ?V at frequencies up to 1 GHz; 16. the dynamic range for hammering is about 85dB, due to characteristics of the applied microcircuit msi001. 17. applied aluminum body; 18. there is a display backlight control; 19. antenna socket, type SMA; 20. dimensions of the receiver 120x88x39mm. Receiver settings cannot lead to malfunction receiver. The user can always reset the settings to the state by default.

Excellent Product Time Owned: 6 to 12 months.
I use a rechargeable 18650 battery and this receiver lasts for days on the charge. Like many SDR receivers it has digital RF filtering, extremely sensitive, a spectrum analyzer audio DSP filtering, a bright TFT touch screen mesmerizing display, extremely lightweight but with one huge difference... very portable and no laptop required! (IMHO recommend a carry case for it..) and unlike other receivers..it has a spectral visualization of the bandwidth it is looking at. It's also a stable receiver on VHF/ UHF. Difficult to find something so broadbanded and battery operated like this. It's a way to check to see if you're on frequency provided that you attenuate the input to a short SMA antenna and there's an attentuator built-in...(The only thing even close to this- is the German Reuter SDR which is very difficult to find without traveling to Germany. The designer of this portable SDR receiver is a Russian software engineer who is a pleasant person to deal with by email -very customer service oriented..and was interested in making sure that I received the package in good working order despite its long transit. I was initially nervous about ordering something from so far away but he followed this shipment. I highly recommend dealing with Georgi the software Engineer.
