New developmentPanda SSB/CW short wave transceiverKit, test, do not beat, thank you for support!2018-6-15

Kit assembly requires a certain electronic technology base(Correct identification of positive and negative electrode of electrolytic capacitor)Please prepare your own tools, such as the multimeter and the electric iron.We do not accept refund or refund due to welding and commissioning without foundation.And the evaluation of middle and poor. Package instructions (electronic version) needsGo to SkyDrive to downloadDue to malicious plagiarism, the circuit diagram of this kit does not contain.Pre weldingPart of the electricityroad.

The dual band (7MHz, 14MHz) SSB/CW short wave transceiver adopts the classic crystal filter circuit structure, DDS local oscillator, and OLED display screen.

There are the following characteristics:

1. The suite is usedMMIC high release+NE602 mixingCrystal filtrationIntermediate release+NE602 multiplicative detectionFrame, intermediate frequency3.57MHzHigh sensitivity.

2, the launch uses the 5W power transmission framework (NE5204+C2851+C1971), the performance is stable and reliable. With ACC interface, it can be used in conjunction with X50 or T50.

3. The local oscillatorDDS moduleCircuitUseAD9851Chip, support10Hz/100Hz/1KHz/10KHz step.

4, the control chip is 51 single chip microcomputer, and the 3 12bit high precision DA is mounted on board to control the gain of intermediate gain, BFO frequency offset and crystal filter bandwidth respectively.

5, board loadingNumerical control volume regulationChip, two output, built-in TDA2003+ speaker, free switching internal and external output.

6, board loadingOLED display, which can be tuned quickly and conveniently.

7, 12V power supply, PCB board size 114*155cm, can be placed49*120*155mmUse in the aluminum box! (The kit will be equipped with a box with holes.)
