Soldering Project Kit.
KARLSON is powerful superheterodyne with double frequency conversion Receiver. It has factory produced EMF (Electro-Mechanical Filter) and fair filter of the first intermadiate frequency. Еhe quality of the receiver is not worse, and sometimes better than modern digital receivers.
The supported bands: 80, 40, 20, 15 and 10 meters. Operation: SSB and CW . Sensitivity: 0.3 µv. Power supply: 9-13.8V DC, when consumed in silent mode 30-40 mA
The features of the scheme are:
- Easy to build
- Electromechanical filter 500 KHz, width 3.1KHz.
- Tunable input preselector,
- Attenuator of the RF signal,
- A simple band switching,
- Duplex, fast-acting automatic gain control (AGC)
- Reference generator 5oo KHz
- S-meter support
- RF gain control
- AF gain control
- Stable operation
The KIT consists of the following components:
- Documentation in Engslish
- High-quality PCB
- All radio components (Filter, crystals, resistors, resistors, capacitors, switcher, etc)
