For working satellites, horizontally polarised yagi antennas will be mounted on a non-conductive crossboom made of FRP (Fibreglass Reinforced Polymer).
A Yaesu G-800DXA azimuth rotator is already on station, so only a system to rotate … Read more...
Adam’s Yaesu G-5500 stopped working 🙁
Meter lamps came on, but non responsive otherwise.
An open circuit diode was found, D3, so no 0V GND rail existed.
Easy to find using an ordinary DMM.
A … Read more...
Adam looks at why the 13V rail appearing on the Yaesu G-5500’s External Control connector drops so much when a Rotator Controller board and 5.0″ Nextion are powered off this rail.
The rear of the … Read more...
Will the VK4GHZ K3NG-based controller boards work with a Yaesu G-5400 and G-5600 system, or anything else?
I’ve been asked this on more than one occasion!
Short answer: Yes the G-5400, G-5600 and G-5500DC … Read more...

The K3NG rotator controller is extremely well supported by the author, Anthony Good, K3NG.
Since the last bug report, one issue, easily overlooked by those not entirely familiar with the Nextion display, has been identified … Read more...
The K3NG Rotator Controller project is aimed towards Arduino Mega 2560 or similar hardware.
Standard ADC resolution on many of the Arduino boards is 10-bit, however the Arduino Due, Zero, and MKR family and Teensy … Read more...
A Yaesu G-800DXA rotator is being used for azimuth satellite tracking being driven from SatPC32 via a K3NG rotator controller interface.
The factory fitted trimpot is only a standard single-turn trimmer, which was awkward to … Read more...
