Soldering Project Kit
Simple 3-band receiver of direct conversion on 7, 14, 21 MHz
The way to air of the beginning radio fan quite often begins with construction simple according to the diagram and construction of the Receiver of Direct Conversion (other name – the heterodyne receiver).
Main technical features:
Ranges of operating frequencies: 7, 14, 21 MHz
Bandpass range of a receiving path (on the level of-6 dB): 300... 2,600Hz
Sensitivity of a receiving path from an antenna input ~0,7mV
Adjacent channel selectivity ~70Db
The current and power supply ~ 10mA, 9-12V
* Note: NEW PCB has 2 modifications on board (choose before checkout):
- Air Capacitor on board
- External multi-turn potentiometer (air capacitor is excluded from this kit)
The Kit consists of manual, all necessary elements for assembly + Air Capacitor (or Multi-turn Potentiometer).
