S-Horse QRP Kit HAM RADIO 20m CW QRP TRANSCEIVER – PIXIE II QRP KIT 14,060 KHz DescriptionNote : this item is diy kit , it is not inclued wifi module 1. IntroductionThis is a very small volume of simple 20 meter band micro-power amplitude telegraphtransceiver, Despite it’s small size and DC receiver limitations, it is capable of workingseveral hundred miles when connected to a good 20 meter antenna. Designed by. It provide the WIFI module, with the mobile phone applicationcommunication. Support automatic key. Provide automatic sending function. Displaysending sequential. Provide acrylic case.2. SpecificationsPower supply: 9~13.8 Volts DC, >500mA (Recommend the use of batteries)Antenna: 50ohm, 14MHz, SWR<2.0Receive: static current 50mATransmission power: 2WFrequency: launch the vibration frequency, 14.060MHzReceives the local oscillator frequency: about 14.060-14.090MHzWork mode: the CWKEY: Manual and automatic auto-detectionAutomatic sending: okConfig: the mobile phone application(WIFI)Case: acrylic3. Circuit principleReference schematic diagram. Receiving part is the core of a NE602, inside it includesan oscillating circuit an a balanced mixer, antenna in the signal after a crystal filter, into the mixer, oscillation circuit at the receiving frequency oscillation, two signals through mixing,directly put the CW signal frequency conversion for audio,NE602 output again gave LM386 audio amplifier, thus complete the receiving process. Circuit consisting of Q4 audio oscillatorto produce about 700Hz sine wave side tone,LM386 amplification, make the headset with "ditick" audio transmission. Launch part using the NE602 oscillation circuit, and then to Q6 dothe buffer amplifier, at the end of the class is made up of class C C2078 amplifier, afteramplification of the high frequency signal after LPF filtering antenna.The WIFI module is optional. If you do not use the WIFI module, you need to short circuitthe JP1, then "S-Horse" == Ordinary CW radio. If you use the WIFI module, you need tounplug the JP1, then you can use the mobile phone configuration data.4. Component selection8050 magnification is about 130, C2078 magnification is about 200. L4 is HFC, ferritebeads in FT37-43 (black) to use the 0.5mm enameled wire around 8 times. L5 is the highfrequency filter inductance in T37-2 on the iron core is circular and (red) using 8 to 0.5 mmenameled wire around.Inductance is a fixed inductance (outsourcing black heat shrinkable casing).Otherdevices, such as 0.47uf for monolithic capacitors, more than 10uf capacitance for aluminumelectrolytic capacitors, all resistance is a quarter w fixed resistance.5. Production process5.1 According to the list of components, check the number of components. Have tools,Electric iron, Solder wire, and A multimeter on hand. Take welding from low to high order,Recommend: Resistance -> Diode -> Capacitance -> Triode -> Crystal oscillator -> Bridgerectifier -> Electrolytic capacitor -> Ic -> Inductor -> Magnet ring -> C2078 -> Other.6.2 Power on: Do not distinguish between positive electrode and negativeelectrode(Internal rectification), Recommend the use of battery, Can also use the DC linearvoltage stabilized power supply. If power on after tens of seconds without abnormalheating,then it’s normal.6.3 Listen to the base noise: Connect the 8ohm headset, after power will hear a slightvoice, then it’s normal.6.4 The receiving circuit test: If connect the antenna to hear the voice and do not connectthe antenna to hear the voice of a great difference,then it’s normal.6.5 The sending circuit test: Connect dummy load, don‘t install WIFI module, short circuitJP1, connect the key, and power on. Now you can use the key control to send, Staticcurrent:40~100mA,Sending current:400mA, In the sending state under the virtual load will be fever. Note: it is not a long time to send.6.6 The WIFI module test: Connect dummy load, install WIFI module, circuit breaker JP1,connect the 8ohm headset, connect the key, and power on. Click “WIFI button” to open aWIFI connection, would you hear “ka ka” sound, then WIFI is opened. Download the APPfrom the www.lxqqfy, using APP to connect the WiFi module to communicate. package： 1pc DIY KIT S-Horse QRP Kit HAM RADIO 20m CW QRP TRANSCEIVER – PIXIE II QRP KIT 14,060 KHz Payment1.We accept PayPal only. 2.All major credit cards are accepted through secure payment processor PayPal. 3.Payment must be received within 7 business days of auction closing. 4.We ship to your eBay or Paypal address.
