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...
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 will.
Long answer:
The answer is in the manual that comes with your rotator.
If we examine the schematic diagram, and for the sake of … Read more...
In this video, Adam goes over the latest Nextion NX8048K050 (Enhanced 5.0″) firmware V2021-02-11-01 update for K3NG Rotator Controller.
Solutions to fix the crappy Yaesu G-5500 +13V rail voltage drop on its External Control connector are also offered.
New: (Suggestion courtesy VK1JA)
Elevation Gauge hotspots.
El can be quickly sent to 0°, 30°, 60°, 90°, 120°, 150° & … Read more...

Nextion firmware V2021-01-07-01 update for K3NG Rotator Controller
New:
Screen Saver Dim To percentage value is user definable on Config page.
Was previously hard-coded to 5%.
Can now be set 0 – 50%.
Fix (5.0″ issue only):
Wrong default font for navigation buttons (Clock & Grid) being set for virgin
EEPROM. Was font 4, should have been font 5

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)
NX8048K035 V2021-01-06-01
First release of 5.0″ version.
• Has all features and … Read more...
Nextion firmware V2021-01-06-01 update for K3NG Rotator Controller
New:
Rotator Protocol added to Features page
GPS icon added & GPS ‘Wait’ on Features Page if GPS enabled but waiting for fix
Fix:
Toggle center button removed – Arduino code doesn’t appear to process Yaesu
commands from Nextion. Never make assumptions!
[Thanks Robert G0MYX for discovering this]
It also screwed up … Read more...

How to interface your Eltek Flatpack2 to the outside world?
To prevent re-inventing the wheel, several options already exist and looking on ebay.com.au we find;
One thing we discover is, ebay cannot count to five properly!
A subtle change in search terms can reveal alternatives, such as the board from Slovenia;
Search results can be inconsistent, even when … Read more...
Extra consideration is required with power supply design if you intend to use a Nextion HMI in a project with audio
Low level noise was being generated by a Nextion (and therefore a TJC) display when the display brightness was reduced down from 100%.
This noise was traveling back down the PSU line into the audio circuits powered off the … Read more...
It’s not everyday you come across a project from somebody else that is well documented, relatively easy to pick up and work with, and, has the ability to customise it to your hearts content!
The K3NG rotator controller is one such project. Ideal for anyone wanting to interface their rotators/positioners with a PC for, say, tracking satellites and/or EME.
