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...

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!

Nextion for K3NG Rotator Controller Update

VK4GHZ Nextion for K3NG Rotator Controller now gets a version for the NX8048K050 5.0″ Enhanced touchscreen.

The 5.0″ screen is nice!

Below are some comparison shots along side a familiar 3.5″ Nextion.

(5.0″ screen still has protective layer on top of screen, so tends to look dull)
