The AR-5700D is a high-end desktop receiver with wide band coverage, from 9 kHz to 3.7 GHz, and with high-performance RF front-end. It supports a variety of digital, as well as analog modes and FM-Video demodulation. When receiving HF stations (under 25 MHz) the signals are converted directly to digital without entering the mixer, this allows very good linearity characteristics. V/UHF signals after the last 45.05 MHz IF are converted from analog to digital by a DSP processor. There is no AGC in the analog circuits as all processing, including AGC, is done by DSP. The first local oscillator is produced by direct digital synthesis (DDS), that method allows frequency switching at high speed. With SD card slot You can record the received audio, analog and decoded digital, as well as logs.
Other features :
IF filter bandwidths of 200Hz, 500Hz, 1kHz, 3kHz, 6kHz, 15kHz, 30kHz, 100kHz and 200kHz (choice is mode dependent).
IF filter bandwidths automatically selected and non-changeable for digital modes.
Simultaneous reception in analog modes: Dual band reception with one frequency below and one above 25MHz. Offset reception with main frequency and sub-frequency within ±5MHz from main frequency (over 25MHz only). Triple reception, combination of one HF frequency and offset reception.
Scanning speed 100 channels per second for analog modes.
Variety of scan functions: memory channels, between two specified frequency limits, cyber search mode (FFT technology, by looking simultaneously at all frequencies), VFO mode, priority mode.
Memory banks customizable from 5 to 95 channels.
Squelch modes: CTCSS / DCS / data-mute.
Very accurate signal strenght values: S-units, dBm, dBuv. As it is measured at the antenna input the displayed level does not change when attenuator / preamplifier is used.
Demodulation support: auto-notch filter, de-noiser (NR), noise blanker (NB), analog voice descrambler (SCR), IF shift, CW pitch, AFC, DTMF.
FFT features: FFT cyber search, 10MHz wide spectrum data display.
