Product Information

40 Mtr Ham Radio Transceiver QRP Forty-9er Kit with instructions

Note:- This is a lot better kit than the pixie with Double Balanced mixer NE602 and LM386 Audio IC, there is also more output power than the pixie with 3W


The PCB 65mm * 35mm * 100mm kit can be easily placed in a standard aluminium box, the kit does not include this box.

Power: 12V
Receive quiescent current: 23mA @ 12V
TX Current: 450mA @ 12V
Transmit Power: 3W @ 12V
Frequency range: TX 7.023MHz, RX receive local oscillator 7.023-7.026MHz
(YOU COULD USE A VFO TO EXTEND FREQUENCIES)

Circuit details:
Receiving section for a typical straight LM386 NE602 plus variable receiver.
Emitting portion utilizes the oscillation circuit NE602, and then to the buffer amplifier 8050, 8050 also as the transmission key, the last stage is a class C amplifier D882, and then send to the LPF after the antenna is connected. There is a Sidetone Signal to listen to.

Recommendations:  full length horizontal half-wave dipole antenna, in conjunction with the use of Simple Balun, antennas should be kept away from sources of interference, such as fluorescent lights, computer monitors, switching power supplies and other equipment as much as possible. to reduce possible interference received.

There are other frequency crystals available on the bay for the Pixie that work well with this kit.
