Product: SSB Double-Band Receiver CW/SSB “Lidia” (40/80 Meters). Soldering Project. KIT DIY
Brand: RV3YF
Color: Black
This is Soldering project kit diy. Receiver "Lydia-band 2" is a simple direct conversion receiver designed novice in ham radio for listening to SSB/CW Amateur stations First and foremost, this project is intended for beginning hams, not having much experience in the design of the equipment. And for radio Amateurs who want a weekend to relax and do radio. The receiver operates in two frequency bands 80 meters (3.5-3.8 MHz or 3.8-4.0 MHz for US) and 40 meters (7.0 - 7.3 MHz). The main element is a MC3361, which is used in most FM receivers with double frequency conversion. In the receiver used: internal oscillator circuits, mixer and active filter. Bandpass filters at the receiver input, in spite of using axial inductors, provides the appropriate bandwidth, sensitivity, and harmonizing with the mixer. Input sensitivity of the receiver is adjusted by a simple antenna attenuator "Level treble" on the variable resistor integrated with a manual gain control. The VFO (Variable Frequency Oscillator) is running in the circuit with the chokes on 80 m and 40 m, varactors and variable resistor configuration. The stability of the VFO enough to listen to the stations. RX PCB dimensitons: 85 x 60 KIT consists of 1. KIT diy of RX board (all elements inside of the kit) 2. KIT diy of frequency meter + 7 segment 0.36" display 3. KIT diy of cabinet for receiver: - Black plastic case dimensions 150х110х78 mm - Black front and back panels. All holes are drilled. - All contrrol devices (LED, knobs for potentiometers, power switcher, sockers, plugs) - 8 Ohm Speaker - Wires for conenctions inside of cabinet - stands and screws for mounting the PCB and frequency meter Each KIT has manual in English! *RECOMMENDED FOR NOVICE IN HAM RADIO or those who want have rest for the weekend and enjoy from assembly of the simple receiver.
