OpenQRP Transceiver Assembly Guide -Rev 0.9Jan29,2024-K1ELIntroductionThere are two additional documents you need to download,the Schematics and the Parts List.Both of these can be found on www.opengrp.org in the column on the right.I have divided the build into small sections which match the way the parts are kitted in theplastic bags.The parts list identifies parts for each section by board reference designators,description,and board grid location.The board grid is presented on the last page of the parts list.Note that in some cases the parts of a section are not always grouped together in one area.As the build progresses,checkout procedures to verify operation are provided.Ground RulesHere's a list of tools and equipment you will need:1)A good soldering iron,pencil type,temperature controlled is a plus.2)Wire cutters to trim leads,small pliers,screw drivers,xacto knife,and wire strippers.3)Small plastic screwdriver/alignment tool to adjust IF cans.4)12-15 volt DC power supply5)Multi-meter,digital is a plus,to measure DC voltage,resistance,current6)Oscilloscope or RF probe.7)Impedance,or LC-meter is not required but is certainly helpfulhttp://www.aade.com/Icmeter.htmhttp://sites.qooqle.com/site/vk3bhr/8)General coverage receiver,helpful for checking VFO9)Small speaker or headphones mono or stereo with 1/8 inch phone plug10)Set of CW paddles (with 1/8"stereo connector)11)BNC interconnect for antenna connection12)Low power watt-meter for peaking TX stages.A frequency counter is not required as one is built into the transceiver.At the time of this writing,the current firmware release is revision E.This provides a veryreasonable set of features.If you are interested in customizing the operation of the radio,theArduino sketch and associated libraries are available for free.You will first need to install theArduino IDE which can be downloaded from www.arduino.cc This will allow you to makechanges to the sketch and compile a new version.To upload the sketch to the radio you willneed an ISP programmer.Make sure you find one that is compatible with the Arduinodevelopment IDE.The best choice is USBtiny which is sold by Adafruit www.adafruit.com and isvery reasonably priced.openQRP Transceiver Assembly Guide-1/29/2024Page 1
