HamGeek TEF6686-5.0-LNA-D-T 3.2" DSP Radio Full Band Radio Version 5.0 Firmware with Preamplifier
Upgrades:
1. The system firmware flashing method is updated to any flash mode. Connect your computer and turn on the radio switch to flash any suitable system firmware at will.
2. Upgraded to a more powerful audio chip. The sound mode has been upgraded to a single speaker with a passive diaphragm. The dual-speaker version is a specially customized version.
3. Continue to improve the compatibility of the body case and motherboard.
4. Improve the test method before encoder welding, and fix the problem that the encoder is stuck and freezes the system interface.
5. Added touchscreen version (Optional. The current firmware version is 1.20B1 touch firmware. The firmware is not perfect, but it is very fun).
6. Enhanced antenna eliminates root breakage.
7. Charging indicator: red light will turn on when it is charging and green light will turn on when it is charged
Features:
- Full-band finished radio
- 3.2" large screen. Strong anti-interference! PCB double-sided full copper! The pcb case is sturdy and durable
- With voltage display (please pay attention to charging below 3.3v) ; the charging voltage is 5v
- Antenna with SMA male connector
- Medium wave, short wave, and FM
- 5000MAH lithium battery
- Size: 115 x 106 x 20mm/4.5 x 4.2 x 0.8"
- Weight: 334g/0.7lb
Flash Firmware:
(1. Hold the boot button of the motherboard. 2. Insert the type-c data cable and connect to the computer. 3. Turn the power-on knob to power on.)
Use the corresponding software of the host computer to flash the firmware. Disconnect the data cable after successful flashing. Reboot. It is finished.
System Settings:
- Volume (audio level)
A converter offset (local oscillator frequency of any converter used)
A low frequency band edge (lowest frequency that can be selected)
- High frequency band edge (highest frequency that can be selected possible)
A level offset (signal table deviation due to cable loss or antenna amplifier/converter gain)
- Stereo separation threshold (adjust channel separation if signal strength is below this)
- High chamfer frequency (cutoff frequency for high points of low signal strength)
A high cut threshold (belonging to the previous option, this is the signal value below which should activate the previous option)
A low level threshold (if the signal becomes very weak, the data crosstalk of the whole circuit can be heard in the sound. With this option you can delay the data stream of low signal strength, ideal for DX)
- Display Brightness (TFT Contrast)
Attention:
- It is not recommended to update the flash firmware by yourself. (Remove the 6 hexagon socket screws in the rear case and use an M3 hexagon screwdriver to disassemble)
- It is recommended to use with LNA amplifier when the outdoor signal is weak
Package Included:
- 1 x Main Unit
- 1 x Antenna
