AM, SSB, CW
HF transceiver Kit 40m (7.0MHz – 7.11MHz)
* NPO capacitors for VFO stage
Just 100mm x75mm transceiver, the receiver section is direct conversion receiver with side tone to hear what you transmit (for Morse code), the transceiver has RIT switch. RIT (receiver incremental tuning) this is a fine tuning control used for CW operation which allows the operator to adjust the receiver frequency without changing the transmitter frequency. You also use it as a fine tuning
The transceiver has audio primary amplifier, audio filter stage with cutout frequency about 3 KHz and audio power stage.
The transceiver has VFO stage and mixer stage (2 ICs “ne602”, one for each stage).
The transmitter use two transistor one for RF primary amplifier and the other transistor for RF power amplifier.
The transmitter has low pass filter (LPF) (3 elements, one coil and two capacitors) in the final stage.
The transceiver has 3 variable resistors, one for RF gain, the other one for tuning and the last one for RIT tuning
Please note this is a kit you have to assemble it by yourself.
Please note the frequency counter is not included (but I include cable with any transceiver Kit to connect it to frequency counter (please check my other items for frequency counter).
