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)
