Yaesu G-5500 Ground Rail Fault & Better Voltage Drop Fix

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 better method of eliminating the voltage drop problem across R10 20 ohm 5W resistor (that feeds +12V to the External Control connector) was suggested by … Read more...

Nextion for K3NG Rotator Controller Update 2021-03-23-01

Both 3.5″ and 5.0″ Nextion touchscreens for the K3NG Rotator Controller receive an update.

Change log as follows:

V2021-03-23-01

New:
• BigGauges page featuring larger Az/El gauges.
  Intended for manual (non tracking) operation ie; similar to using a real Yaesu G-5500 controller.
  Gauges made as large as possible, so there aint no room for tracking status icons etc!

Fixing Yaesu G 5550 13V External Control Rail Voltage Drop

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 Yaesu controller has an ‘External Control’ port, intended to connect to a computer interface.

 

 

The 13V rail for powering external equipment is only … Read more...
