For the second time we will attend Dayton HAM vention. RGO ONE will be ready for real tests on battery power and portable MFJ antenna from flea market area place #1804 (very close to the flea market entrance)
RGO ONE operating manual is ready and can be downloaded from here: manual ver. 2.00a from july 2020 –> manual ver. 1.01b from june 2019 manual ver. 100b from april 2019 RGO ONE BLOCK DIAGRAM RGO ONE technical supplement (BOARDS
Front panel consist of two boards. One of them is CPU board with main microcontroller AtXMEGA128A3U-AU, main dial optical encoder BOURNS, mechanical encoders, dual concentric potentiometer AF/RF. This board holds LCD&switch PCB.
Serial number three (190003) RGO ONE HF transceiver is alive! Yesterday we finished assembly and adjustment process so it is ready to go. First production lot (10pcs.) will be with serials between 190003 and 190012. We will reserve number one
RGO ONE Main Board (MB) or so called mother board fits all connectors on the rear panel, power supply, I/O controller (second CPU). MB is also intended to be a chassis for all RF boards and options, as long as
LO board provides all oscillator signals needed for signal conversion and mixing. The board consists of the following components: – LO first oscillator realized by U2 – SI570 (570CAC000141DG), 3 switchable low pass filters: 10.8-15MHz; 15-24MHz; 24-39MHz. Filter switching is
RX MIXER standard is ADE-1 diode ring mixer. Here described is optional high dynamic range H-mode mixer. The schematic and original H-mode mixer concept has been designed by Colin Horrabin G3SBI and further developed by Martein Bakker PA3AKE. PCB component
RF MIXER board does all RX/TX signals on IF and operation frequencies. On receive the signal comes on CX3 coaxial connector, then passes (or not) through input attenuator R10,R13,R14, then via switches come to BPF board. IF TRAP circuitry consists
Power amplifier building process: Power amplifier consist of two sandwich nested printed circuit boards – PA linear 55W board and low pass filter module.
