DeepSDR 101 Receiver. Like new condition.

Description:

Deepelec DeepSDR 101 is a DSP digital demodulation radio based on SDR architecture. It features a 192kHz wide spectrogram and waterfall display. With 16bit sampling, it is a high dynamic receiver with CW, AM, SSB and FM demodulation functions. The whole machine adopts all-aluminum alloy CNC shell, with a 4.3-inch 800x480 resolution high-brightness IPS LCD display.

This product realizes frequency mixing based on the Tayloe Quadrature Product Detector method. Clock generator Si5351 generates two quadrature square wave signals with variable frequency as excitation and realizes an ultra-low noise ZIF zero-IF receiver. The IQ signal obtained after mixing is output to the CODEC and collected by the MCU, and the DSP algorithm in the MCU completes the demodulation and display of the signal.

Display Control Parameter List:
12 optional parameters for the encoder:
1. Channel selection: 1-99
2. Frequency setting: 100k-149MHz, minimum step 1Hz
3. Speaker volume (SPK): 0~35dB, step 1dB, OFF is closed
4. Headphone volume (EAR): 0~35dB, step 1dB, OFF is closed
5. Demodulation mode: CW, LSB, USB, AM, WFM, STE (FM broadcast stereo), I/Q
6. AGC settings: OFF, SLOW, MID, FAST
7. Reference level (REF): -99 to 99dB adjustable
8. Backlight brightness (LCD): 1%~99% adjustable
9. IF GAIN: -12 to 67dB, step 1dB
10. Spectrum style setting: switch to display green fill, green line, blue fill and white line
11. Spectrum bandwidth setting: switch to display RF spectrum (192kHz, 128kHz, 64kHz) and audio spectrum (64kHz)
12. Waterfall chart setting: switch to display waterfall chart and time domain waveform chart (1 times, 8 times, 64 times amplitude)

5 parameters that are not selectable by the encoder:
A. Battery level display
B. Date and time settings
C. Station information display: preset station name
D. Display of current spectrum bandwidth
E. Power display (POWER) real-time display

I recommend the use of a good receiving outdoor active loop antenna like the MLA-30 plus for shortwave/ Ham reception, any good outdoor antenna will work fine, but the active loop seems to do a better job with long distance reception.
