It delivers 1.2W transmission power with a wide 9-13.8V DC input range featuring reverse polarity protection. Equipped with LED and buzzer indicators, it offers clear transmission feedback. Housed in a transparent acrylic shell, this kit combines hands-on assembly with a sleek, modern look, making it a must-have for amateur radio enthusiasts eager to master Morse code and QRP operation. ## Description Power Supply: DC9 ~ 13.8V (recommended linear power supply or battery), does not distinguish between positive and negative Antenna: 50 ohm, 7MHz, VSWR 2.0 or less Receiving Quiescent Current: 20mA Emission current: 120mA Transmitting power: 1.2W Frequency: The oscillator frequency emission; receiving local oscillator frequency Mode: CW Key: Manual key Automatic transmitter: Not supported Sidetone: None he circuit principle: See schematics: with the surrounding elements constituting a typical Colpitts oscillator and keeps oscillating (it has about 1mW when receiving an oscillating signal leakage), the LO signal is coupled directly to the capacitor 8050. In transmit state (key press), 8050 as a C class amplifier, the signal is amplified by 100nF capacitive coupling to the π-type low-pass filter, and then send the antenna; in the receiving state (key release), and around 9018 elements constituting the beat oscillator (BFO), 1N4001 plus high-voltage, direct current with capacitive pressure is increased at both ends decreases, the natural frequency can be increased to about 0-3KHz, can be easily received signals of 7.023MHz beat . 8050 is biased in the non-linear region (the transistor is then two diodes back to back), and the signal received by the antenna BFO signal for mixing, mixing the audio signals obtained through coupling to the 0.1uF capacitor constituted LM386 audio power amplifiers, audio signal amplified by the LM386 5 feet 10uF capacitor blocking evacuation headphones. Key not only control the LM386 power on-off switch is also biased varactor D2, so that volume changes in different states. Review: A right of passage for Amateur Radio afficianados ! - Fun, inexpensive little kit that anyone who is interested in radio communications should build and enjoy. Although there is very little included in the way of instruction, there is enough documentation online to complete it easily. All the parts were of decent quality and the Lexan box gives it a bit more of a finished looked. Review: Great little CW Transceiver for training. - This is a fun little project to build a 1 watt QRP CW transceiver. The kit is well designed and the build instructions are easy to follow. The case is well made and fits like a glove. It comes with two crystals so you can choose which frequency you would like to transmit on. I now have an inexpensive unit to practice my CW skills. It is surely a low cost tool to help you learn morse code. 73 W4WQC. ## Features - "PIXIE" is mini the 40 meter band simple micro-power amplitude telegraph transceiver, 9 ~ 13.8V DC power supply - Resistance to change is a horizontal packaging vertical packaging, easy to solve the short-circuit resistance has long been a problem. - Power input does not distinguish between positive and negative, and to improve the power supply range, the user can easily use 13.8V communication power supply, and do not worry about the positive and negative reversed losses. - Increasing the transmitter side as the buzzer sound prompts (using a jumper cap shielding sound), an increase of LED lights as transmitters prompt. - You will receive the balun kits with the instructions.Or please contact the seller for the PDF instructions.

I've never used an xtal other than came with the kit. But, I've talked to others that have. **Q: What power jack does it use?** A: 2.1 barrow jack **Q: How to I make sure I get the 7.050mhz crystal?** A: The order came with both of them. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A right of passage for Amateur Radio afficianados ! *by B***L on April 28, 2026* Fun, inexpensive little kit that anyone who is interested in radio communications should build and enjoy.
