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.
By now all printed circuit boards are ready and populated. We have also some boards – completely tested and aligned: 1. IF/AF board 2. RF MIXER board 3. LO/tones board. 4. Front panel assembly – CPU, LCD/switches boards 5. Both
Today we made continuity and DC test of the front panel assembly consisting of: CPU board LCD&switch board All tests passed OK and tomorrow face panel’s CPU will be flashed for the first time
We recently received first ten sets of printed circuit boards for RGO ONE HF transceiver. So till today we managed to populate some of the boards. Rgo one consist of 20 pcb’s … so a lot of work lies ahead.
Search and pounce in LZ DX contest with RGO ONE. Testing new features – DTR/RTS keying from N1MM contest logger; Testing temperature management with new FAN cradle.
