Discussing This Website On Amateur Radio

Due to the fact that I hold an Amateur Radio License and that this website deals with Amateur Radio Gear, I make the following statements. This website doesn't make any money, it's NOT A BUSINESS, never has been. Matter of fact, it costs me money every month to maintain this website. I DON'T solicit, ask for funds or funding. There's NO irritating or scamming Website ads.
EVEN SO, I will not discuss this website while talking on the Amateur Radio Bands. It can still be misconstrued as a business and cause unfortunate problems for all parties involved in the support and maintenance of this Website. Please understand the reasons behind why We take this stance. Thanks for YOUR full cooperation and understanding in these matters.

...Updated EDDC Code ...Propagated pending code from June...
Me, AG4OJ, this time of year is the hardest time for My disabilities and medical problems (Military, VA caused). My last two helpers, programmers/developers, and I will continue things here, just at a much slower rate until January 2022. There is always a Email address at the bottom of this page to ask for any help. We usually will get back to You as soon as We get Your Email.
Many have come here to learn. We hope this Website continues to be a stepping stone or stones for all. IF you see something that doesn't look right, or work right, send Us an Email. We'll help you with it, even if We have to fix something, that's what all of this is about, freely sharing, and even Our Own graceful, humble learning. Only death will stop Our learning and sharing.

The MMDVMHost Missing t31 Location Message

ATTENTION: Our NDC Version A has always supported the ON7LDS Nextion Display Driver Code. We continue to support the NDDC as best We can. There has been a posted update to the ON7LDS Nextion Display Driver Code, v1.20. Please update it from the standard methods. There are alternate update methods also available on the EDDC Part Of The Website.
IF you are already using the EDDC on this website, then you are safe from this latest shift in the MMDVMHost / Pi-Star. We already knew about the changes in the MMDVMHost (08/27/20) and added messages to the EDDC to cover this. We just didn't know when this problem would rise to the occasion in Pi-Star, which is obviously now (06/07/21). TEAM AG4OJ, ENJOY!

The History Behind These Screens

Keep It Simple Screens for Nextion Displays, or KISS/ND, was born out of necessity. My eyesight is not good, I'm legally blind. Trying to watch the screen on the handheld for contact info was not good and the screen that came on my hotspot wasn't built for poor eyesight either. So, instead of complaining, I decided to program my own screens for my hotspot that I could see better.
When another Amateur Radio Operator heard that I was making my own screens, they wanted to try them. This is turn gave birth to creating even more types, sizes, and orientations. This then spread word of mouth and suddenly I needed a place to host them, this Website was born. I then gave in to requests for more Nextion Basic versions, and this grew even more.
This Website has become a looking place not just for visually impaired screens, it has become a place to look for all screen types, sizes, and landscape orientations for Amateur Radio Hotspots / Repeaters. So, over the August / September 2019 time frame, a version was put together for every display type, size, and landscape orientation.
That was mid 2019, Now in 2021, these projects have become a group effort.

All About Me, OH NO! Say It Isn't SO!

 Bill - AG4OJ
I've been A Professional Audio, Video, Broadcast, And Computer Engineer for over 40 years. The ending Title on my name, PE, Professional Engineer, a title earned through years of hard work, not pedigreed or bestowed upon, A Badge Of Real Honor, The ONLY True Battle Of Professional Engineering. My History & Knowledge Includes Extensive Forensic, Restoration, & Broadcast Disciplines.
I served my Country in the Military, The United States Air Force. I'm a Severely Disabled Veteran from that service. My MSCDs and PTSDs are what they are. (OCT1984) VA medical malpractice just added to it. (AUG2015) I've continued to served my Country in ways most never would. Once a Federal Employee, always a Federal Employee, that rabbit hole is deep and ever so demanding.
I've held Amateur Radio Licenses since 1977, my callsigns which have been WB3KRL, KC4IXV, KO4VJ, KF3CB, and now finally, AG4OJ. All Callsigns have been assigned by the FCC, NO Paid Vanity Callsigns. I give back as I can, like this website for example.
My Final Notes about myself; As God takes care of me, my daily needs, and some of my wants, I do, as I can, freely provide this website. Creating this Website, the files, the documentation, has kept me busy around my remaining abilities and keeps my mind off my Military / VA caused disabilities, which can be overwhelming even on the best of days.

Some Nicely Expanded Quotes

"It's the Flowers we love to enjoy (The Praises When Everything Appears To Work Right), yet, it's the thorns that makes us have to address the bleeding! (When We Find Our Broken, Bad Code)" Are You Learning From My Lead?
"Leading the way into insanity and confirmed ultimate madness only requires one to do the same thing over and over again, always expecting different results. There is NO gerbil on the hamster wheel here, running for dear life, and getting nowhere fast! We're doing different things, getting better results, and going there very fast!" Did you just FEEL my wind?
"When the DEVIL is in the details, even GOD has to be proud! It's the synergy of the catch, the added mysterious hidden elements, the yin and the yang that's so surprising when exposed to light in the end! Thus seeing that even God can't deny that GOD is the creator of all things!" Will You Rise Above All Things With Me?
"Keep Your Friends Close And Your Enemies Closer. That is until you have learned all you can from them. Until that time, to be on one's own toes and alert to one's surroundings as these malicious people are always present. As they try to wreak havoc in one's life, one, being well prepared, is then always three steps ahead of them." Into Dodging Bullets Are We?
"Karma is the drink best left for your enemies to indulge in. It's when a multitude of evil things done by them is what filled the drink up in the first place." WAIT! Tell me again why you say you must be the one to drink that drink!?
signed AG4OJ / Professional Engineer, Part-time Philosopher? Really? Yeah, Right! Staying in my lane! HA!
As Always, ENJOY! AND, Make Sure You, PAY IT FORWARD!
