Feature: 1. [Versatile SDR Transceiver] As a software defined signal peripheral, it can transmit or receive signals from 1 MHz to 6 GHz, supporting testing and development of radio technologies. 2. [User Friendly Panel] Featuring a 3.2 inch, 240x320 RGB LCD screen with a resistive touch panel, four direction arrow keys, jog wheel, and select button. 3. [Multiple Reception Modes] Supports SSB, AM, narrowband and wideband frequency modulation audio reception, this SDR receiver provides wideband (18MHz) spectrum analyzer and waterfall charts. 4. [Monitor Various Signals] The SDR radio can monitor signals from boats, cars (TPMS), and utility meter transponders (ITRON ERT), providing comprehensive signal coverage. 5. [Precise Tuning] PM calibration enables more accurate tuning, providing precise signal reception and transmission on this software defined radio. 6. [Energy Efficient] Features a rechargeable 2000mAh lithium battery, with power saving sleep mode to extend operational time and improve energy efficiency. Specification: Item Type: SDR Transceiver Material: ABS Working Frequency: 1MHz to 6GHz Transceiver Type: Half duplex transceiver Sampling: Up to 20 million times per second Quadrature Sampling: 8 bit (8 bit I and 8 bit Q) Suitable: for GNU Radio, SDR , etc. Configuration: Software configurable RX and TX gain and baseband filters Ports: Software controlled antenna port power (50mA at 3.3V) Connectors: SMA female antenna connector for synchronous SMA female clock input and output High Speed USB: 2.0 Screen: 3.2 inch TFT 240x320 screen Battery: Rechargeable lithium battery 2000mAh x 1 (built in) Memory Card: Microstorage card (without) Catching and Playback: 1. One of the best things about this radio transceiver is that it makes catching and playback of wireless signals like those from ISM band remote controls extremely easy. 2. To create a catching. You just need to enter the Catching menu, set the frequency of the remote key, press the red R record button and then press the key on the remote. 3. Then stop the recording to save it to a storage card. 4. Now you can go into the Play menu, select the file that you just recorded and click play. The exact same signal will be transmitted over the air, effectively replacing your remote key. Microphone TX: 1. Using the 3.5mm audio jack, this radio transceiver can also be used as a standard Push to Talk or voice controlled intercom. With a microphone plugged into the audio jack, simply hold down the right button to push to talk. 2. If required you can also enable multiple CTCSS tone options, as well as tones that look like they enable transmission to wireless headphone. Other Transmitters: 1. There are generic OOK transmitter which can be programmed with custom data. This mode might be useful for experimenting with simple key chains, or things like home automation switches. 2. There are numerous transmit modes implemented that are questionable in most countries and could get you into huge trouble. These transmitters are purely to be used for internal testing with a faraday cage Receivers: By connecting speakers to the 3.5mm audio jack you can easily listen on standard NFM and WFM audio signals. ADS B reception can be easily enabled by selecting the inductor and sign on the top right. With the bias tee enabled you can receive aircraft. . Package List: 1 x SDR Transceiver (Storage Card Not Included) 3 x Antennas 1 x Connecting Cable 1 x USB Cable Note: 1. Make sure to support the latest firmware, the current firmware defaults to for Mayhem firmware V1.9.1. 2. To use certain features such as world map, GPS simulator, etc., you will need to prepare for H2M and a Microstorage card with a capacity of 1GB or more formatted in FAT32.
