Frog Sounds HAM Radio QRP Kit Telegraph CW Transceiver Receiver Radio Station The PCB will have the different colors, But the product itself is not affected, please note that before you buy it ...... We have Confirmed from the supplier, even The PCB is different colors, it still can be used, if you got any problems when you finish soldering the Yellow PCB, please contact us to ask for help quickly...... Description: This is a very small volume of simple 40 meter band micro-power amplitude telegraph transceiver, the DC power supply using a 9V battery or an external 9-12V side of. In relatively good spread, they can communicate with amateur radio within the range of several hundred kilometers.This machine was first introduced by domestic radio enthusiasts, and gave it played a nice name "frogs" Feature: Power: 9V-12V (12V linear regulated power supply is recommended) Antenna: 50 ohm, unbalanced Transmit power: 1.9W (using 9V power supply) 2.6W (using 12V power supply) Frequency: The oscillator frequency emission: 7023KHz; receiving local oscillator frequency: about 7023-7026KHz Working Mode: CW Note: MOSFET 2N7000 kit to be used as a final element of soldering, in order to prevent electrostatic breakdown, 2N7000 soldering iron should disconnect the power supply heat soldering Factors affecting communication distance are: antenna and erect, spread bad weather, the surrounding environment is electromagnetic interference, individual operational level. The kit is CW manner (similar to the previous telegram) not speaking Package included: 1 x Frog Sounds HAM Radio QRP Kit Telegraph CW Transceiver Receiver Radio Station

DRA818U UHF Band HAM Radio Wireless Audio Module - Dark Blue + Silver

827.43 руб.
DRA818U is a type of UHF band wireless audio module based on RFIC RDA1846. It has the same pin sequence and dimensions as DRA808M module so users can replace the DRA808M with it directly. Comparing to DRA808M module DRA818U are added with CDCSS function except CTCSS and AT command-SETFILTER which users can use it to turn on/off Pre-emphasis/De-emphasis funciton high pass filter and low pass filter. It integrates high speed microcontroller high performance wireless transceiver IC high power PA audio process and squelching circuits. The DRA818U module provides two power levels (0.5W and 1W) for selection. It has standard UART interface with which users can easily configure appropriate parameters for different applications. Users can easily construct a walkie-talkie system by connecting external microphone audio PA and speaker.
