Re: Email still coming in no email button selected
I haven't followed your thread so please excuse if my suggestion has been offered.
After you check the no subscribe button scroll down the page, and hit the save button. I don't know if this is necessary but may be worth a try.

Hey Todd !!!
?
making the shoes to the flea on the schemes does not seem to me a constructive way to experiment !!!

I think the fantasy is dead !!! ... I have read many posts in this forum and I have come to the conclusion that humanity is shrinking more and more to simple and robotic stacks ... if something is not standardized it is out of the understanding of the robotic minds of the new computer humanity! !! !

Use a little imagination, if something is not "strictly" codified, USE IMAGINATION !!!! fly over the nonsense and get to the point !!!! you may discover the immense pleasure of using the brain !!!!

uBitX v.6 schematic / driver and finals transistor symbols /
#ubitxv6
#v6
Folks, On Farhan's schematic for v.6, the pre-drivers, drivers, and finals transistors are drawn in a way I've never seen before. There's solid lines from the base of one transistor through the circle body of the transistor to the base of the next transistor. Examples include Q911 & Q912, Q92 & Q93, etc.  Is this a shorthand way of drawing parallel transistors (i.e., the bases are connected together)? Thanks! Todd K7TFC

Re: SWR meter with second arduino
Hello Dennis,
Thank you for your information
So far I don¡¯t have a second Nextion. (In 2021?)
So my edit would be a main 5-inch Nextion and a 3.2-inch Nextion in secondary. So it should work.
Afterwards, I was wondering if it was possible to add an audio equalizer that we could drive with this 2nd screen. There are circuits controllable by the arduino.
with a?MSGEQ7.

Hello Raj
It doesn't matter which bands he wants to experiment on, even in SHF they never experimented on 3.4 GHz ... but now we're losing the band all over the world! ... private interests go in the diametrically opposite direction to "man's individual happiness" as Kennedy said "gross domestic product can measure anything but not human happiness"!

Re: SWR meter with second arduino
You might be interested in my project.? ?I have created a major revision to Dr. Lee's standalone I2C with a bunch of enhancements, including a way to calibrate the power/swr meter.? Included is my tweaked Nextion firmware for 3.2" display that includes the power/swr meter integration.? It is at:

Are you using the second Arduino for the SMeter?? If so, then the speed is based on how the code is written and the communication mechanism with the Nextion.? I have replacement firmware for the second Arduino that makes the SMeter much faster (but if you turn on the FFT function is gets slow again).? My project can be found at?
If you have not already used the second Arduino, I highly recommend you first get things working with Dr. Lee's original code, using his documentation before trying my new version.?

Dennis, the uBitx version is the 5, 3.5 inch Nextion, Firmware 1.20 from KD8CEC.

I fervently hope that your experiments are not oriented to occupy the HF with telephone or other "private" digital communication networks, private communications are already "eating" us the UHF and the SHF to allow the allocation of digital networks of nature certainly not experimental.
I do not think that radio amateurs around the world ask for the impossible, but only to be left in peace to enjoy their QSO and their experiments, without being "victims" of commercial purposes that certainly do not care about " human right to happiness "!

Hello Bob,
For the use of old radios, I almost agree with you, but 40 or 50 years ago there were already on the market beautiful and indestructible specialized radios for HAM, such as Collins, Drake, Kemwood, Yaesu etc., the passion for the "repair" and "modification" of the radios present in the radio amateurs' Shacks did not arise from the need to maintain the equipment in efficiency, but from the pleasure of "experimenting" new things and learning the techniques and theory of communication (see ITU assignment of Amateur Radio Service) ...
Unfortunately this has been lost over time ... but not for the fault or defect of young radio amateurs, but for purely "commercial" reasons, the construction of the SMD equipment has made it practically impossible for most to modify the circuits, the excessive " digitization "of products has led Radiomators to be not experimenters of communications but software geeks ...
It's a shame, but the habit of throwing away will inevitably lead to the death of the Amateur Radio Service! ... even KITs like the ?BITX have suffered the same fate ... too many costs to assemble a board with discrete components and the "all do it yourself" KITs like the Russian ones are not suitable for "novices" or for those who they have to learn electronics before they make them ... I see a sad future for "us" ... I just hope to have passed away before the last frequency bands are removed from Ham use!
I would really like to know who cares more about "the right of men to happiness" ... bha ... you will probably have to amend yours constitution, so I'm afraid it is already obsolete! ... Such a pity !

The book is a pretty complete introduction to the C programming language, especially as it would be used in a microcontroller environment. Rather than me trying to summarize it, you can go to the Amazon web page:
and click on the "Look Inside" banner that is on the book's cover. I would then suggest that you look through the table of contents and you will see what is covered. I even have a chapter on C++, because all of the Arduino (and other) libraries are written in C++. The goal is not to teach C++, rather it's to make it easier for you to use the hundreds of libraries that are available to you.
It comes in both eBook (the "Kindle" button) and printed (the "Paperback" button) form, so if you're thinking of one versus the other, click on the appropriate button when ordering. You can then click on the "Add to cart" or "Buy now" button just like any other Amazon product. The narrative is the same for both books.
The book has not been out very long, but there are 18 reviews you can read. For reasons I don't understand, it says the book does have one 1-Star review, but when I go to read it, there is no 1-Star review. If you want more reviews, the teaching method is the same as I used for Beginning C for Arduino which has over 90 reviews.
If questions remain, just ask.

I wrote to KDP to see if I could get the mailing addresses of the people who bought the book. For reasons I can understand, that request was denied. So, here's the deal:

It's an imperfect solution to a nettlesome problem, but the best I can come up with.

Some of the old vintage radios and amplifiers are real hunks of steel compared to what we use today but never forget that we won wars with those old relics. Also, some are still used today; when I worked at two Army Depots, some of that old stuff was refurbished and sold/given to foreign allies to use in their military even though we had quit using it here in America. And they were happy to get it.
Many of us can remember using the old vintage transmitters for ham radio usage as well as adapting them for antenna tuners, etc. Wartime antenna components are still in operation today by many hams.
Will some of the stuff that we buy today endure like that wartime equipment? I wonder but maintenance today is not what it was back then. If some ham's equipment goes sour, the item is often thrown away (or set on a back shelf) and a new one bought and this is often a distinct improvement over what they had used before. Technology has improved but the oldtimers' willingness to repair is not what it was in years past mainly because something 30-40 years old is not going to give us what the new stuff will give us ... so why bother? Back then, though, it was not done for pleasure along, repairs were done because it was necessary to get back on the air.
Out with the old and in with the new is the way more in common today.
