Re: CW OPERATION

It has to be programmed to work that way, but we do it in all of our recent sketches. There is no reason why it can't be programmed in the other sketches if the programmer choses to do so.

Hi, I just want to be sure I understand. The PTT line can
be used for straight CW keying? It seems reasonable,

Thank Jerry, but in all of the software put out by the Triumviratw Skonk
Works from our first public release for the original NANO and ever
since, CW has not only worked properly but the Keyer has too. We
figured out early on that using the voltage divider was NOT and still is
NOT the way to go. Using 2 inputs and learning how to use the available
(timer not pin) interrupts properly works just fine. Our software
(written mostly by Ron, W2CTX) addressed the CW problem early on.

There is no need for me to use Ian's sodftware as it is so full of
work-arounds, not fixes to all the problems that have cropped up that I
refuse to use it. His source code is so convoluted that even the most
experienced programmers on this group have given up trying to fix it for
him.

The Nextion display is getting so cluttered up with extra buttons &
menus that you almost can't read the frequency on it any more. It
started out being a pretty nice addition and now is so cluttered as to
be almost unusable. It's also a "Single Source" display with a GUI
editor that most people can't even figure out how to use. Where's the
utility in that?

What are all of those who spent and are spending LOTS of money just for
the Nextion display alone, trying to make their uBITX $119 or $129 kit
radio look like a $2000 or higher big name radio going to do when that
Chinese company decides to charge hundreds of dollars for the use of
their editor (since it seems to have gotten popular) and raises their
prices astronomically for the Nextion because they are selling to the
hams at such a rate or quits production because the market dries up?

Frankly, the original LCD was quite adequate for a rig of this caliber
and all of the problems involved in using it should have been addressed
before even thinking of trying something else.

By the Way, the TSW DID that. We went to using the (easily accessible
on the original Raduino) I2C bus to drive the display (added minimal
extra cost and freed up a bunch of digital lines to use for the CW Keyer
and other controls.

Also, now that Ian HAS implemented the 4 wire (power ground, TX & RX)
Nextion interface that leaves 8 digital I/O pins freee on the old
display connector. Why has he not solved the major CW problem by
dropping the voltage divider altogether and using digital inputs for the
paddles dot and dash inputs? Switch the hand key portion of the keyer
over to use the Push To Talk (PTT) line, wire the hand key to use the
mike jack if you don't want to add another dedicated jack. This allows
auto select of hand key or paddles just by hitting the hand key or
pressing the paddles. Ask Ron, it took minimal code to do this. You
don't need PTT in CW operation and you don't normally need the hand key
in SSB operation so the PTT wire is easily co-opted for this.

By the way, this is not meant to be a rant though it may be turning into
one. I've seen many people complaining lately that the keyer doesn't
work properly but nobody has proposed or made a proper fix to the CEC
software. TSW has had the solution almost from the beginning but
everyone has drunk the "Nextion" kool-aid and the programmer for that
has chosen NOT to fix the CW issue. TSW has also tried to provide
readable and understandable PDF files explaining how our programs work
and any (usually minor) hardware changes necessary to make it work.

Ian's software is the most popular update available for the uBitx.
He has added a lot of functionality to the rig and that is to be
applauded.
It's taken months of free time for him to bring it to this level.
Could well be that Ian doesn't use CW much, and CW is not a priority
for him.

Getting an iambic keyer to feel right is best done by a serious CW
operator.
I'd think Jim Sheldon would be an excellent candidate.
