AVT2148 B

This small receiver CW-SSB / 80 m is used to receive (listen) amateur stations working with telegraphy and single-hook sound in the frequency range 3.5-3.8 MHz. Small dimensions make it an ideal 'companion' during holidays or holidays. The use of a modern integrated circuit and ceramic filters has simplified the construction significantly and made the receiver easy to start up. The TDA 1072 has blocks of an RF amplifier, an unbalanced mixer, a tunable generator, an IF amplifier, an ARW system, an S-sub amplifier, etc. After completing the scalpel with a handful of additional elements, despite the system simplicity, the kit offers very good parameters listening. Low power consumption means that you can use the popular 6F22 battery for power supply. The output signal can be directed to the loudspeaker or headphones.

The device is especially recommended to all amateur radio enthusiasts, those who do not like to part with their hobbies even during holidays or holidays
