That's the way I learned, and I peaked out at about 18wpm. Also, I think you tend to count dits and dahs more when you use a pencil...not good. For those who can type, I think that's probably okay, since a lot of people can type at 60wpm. Also, the real goal is to listen to the rhythm of the code. For example, if someone sends "BEEN" or "BEST", I will hear that no matter what because I like their rhythm. Proficient CW operators (e.g., > 30wpm) never seem to use paper. They hear word rhythms where I still hear dits and dahs. I'm working on it, but it takes a lot of practice. Our club president can copy about 40wpm...he sits there with his eyes closed reading the code on the back of his eyelids...and he's almost always smiling. Most of us know the "word rhythm" for CQ. Imagine having that for every word! I really hope to get to 30WPM before all the sand runs out of my hourglass.

In the military intercept operator were trained type the inoming CW on a MILL!
 
They never used a pencil/pen and paper.
 
Airborn operators did use a pencl/pen to write orders in their log. Airborn (liason) operators sent very little. In some aircraft they were also GUNNERS.

Yes, Slackware user back in the days, also.

Kernel version 0.99pl14

Had to load it from a big stack of floppies.

My first CD distro was Yggdrasil, same kernel version.

All on a 486, and I splurged on 32MB of RAM - cost me USD$1000 in those days.

I was a machine vision developer at the time, and used Sun workstations at work, running SunOS 4.1.3U1 (the U1 meaning "You won", because Sun was going to drop support for SunOS but was badgered into putting out 'one more update')

Used Emacs and GNU960 cross-compiler tools from the FSF, which came on 5 1/4" cartridge tape, hosted on Sparc processors, targeting i960C-core processors that could do a C loop in 2 clocks.  We were driving a SIMD array of 128 parallel vision processors, created in Lattice 10K gate arrays.  At 25 MHz clock speed, we could do binary morphology on a B&W video frame in microseconds.

Heady stuff, then.

Re: CQ WW DX CW 2019

Michael St.James
 

I like to get on the air with my QRP signal during the last two hours of a contest. My CW speed is only 11-12 wpm and rarely do contesters listen to me. But in those last two hours the really good ones would rather catch my call than log another duplicate. It worked last year. I logged 20+ contacts from hams who wanted that one last callsign in their log. Contests can be fun .... even for the “little guy.”

Kind regards,

If you only have a QCX and you want to play in the contest it still

Hans,
 
I do most of my coding in assembly langusge. It is more tedious but is more memory effiant.
 
I started with assembly language about 1970 and I am very comfotable with it.
 
Your 807 transmitter is similar to the first one I built in 1957. Mine came from the 1949 ARRL handbook. I used it for my novice year.

Hello Bob

Yes I realize the AVR programmer isn't necessary when you have a serial bootloader. But then you need a USB to Serial adapter. It's almost the same piece of hardware as the AVR programmer. 

Again, the reason the QRP Labs kits don't have bootloader is because I pack in a lot of code into the 32K Flash and in some cases (U3S, QCX) use almost every byte. Furthermore I use every I/O pin, sometimes multiple times (shared functions). 

I'm trying to pack maximum features into minimal resources, provide great feature-packed kits at low prices! The serial bootloader doesn't really give us any major benefits, so isn't considered a high priority.

My 807 transmitter winter project (assuming I ever have a free microsecond)... https://www.qsl.net/k5dh/6ag7_807.html ... I have all the parts except the crystal and 6AG7, which should get here in about a week from now. It neither needs a bootloader nor an AVR programmer ;-)   But then again, the 700V supply is a bit of a pain (particularly if you touch it). A reminder that all is tradeoffs!

You can buy ATmega328 chips with the bootloader already installed if you don't have a ISP programmer.
 
I don't use the Arduino (POS) IDE. I use Atmel (AVR) Lab. I like it. It's better than the Arduino POS.
 
I do install my bootloaders with my AVRISP MkII. Then I use AVRDUDESS to load my application programs via a serial port.
 
But the QRP Labs design is just not really compatible with the serial bootloader. In addition to the Tx/Rx lines it reqiures RTS or DTR to do a chip RESET. That starts the bootloader.

Hi Bob, all
 
The problem is the QRP Labs products are not designed to be programmed with Arduino bootloader.

I'm not sure I'd call it a "problem". Why would I include an Arduino bootloader... I program the chips in C, not using the Arduino infrastructure which is rather bloated for my purposes; had I used Arduino I would not have been able to achieve so much functionality in such a modest device.  
 
NO SERIAL PORT AVAILABLE.
 
So the only option is a ISP programmer.

Even if a serial port were available, for most people they would still require a USB to Serial Port adapter. Which is a little board very similar in size, functionality and cost to an AVR programmer... so not much different. Direct use of USB requires a more capable microcontroller; the QSX will have direct USB interfaces and requires no programming hardware or software to do updates see https://www.youtube.com/watch?v=xzOv9szPnhI

To summarize regarding QCX (and other QRP Labs products) firmware:
  • QRP Labs code is nothing to do with Arduino. They just both happen to use the same ATmega328 processor. 
  • There is no bootloader; all the limited program space is required for the large amount of functionality packed into 32K Flash
  • The chip can be programmed either in place on the board, using the 2x3-pin ISP header; or, if you pull the chip out and put it in a programmer with a socket such as a ZIF (Zero Insertion Force) socket. 
  • If programmed in the QCX, the QCX should be powered.  
  • An AVR programmer can be used, or an Arduino can be used with the Arduino ISP sketch which just makes the Arduino behave equivalently to an AVR programmer (there is no difference). Despite the fact that the Arduino can be programmed to behave as an ISP, the QCX still has nothing to do with Arduino. 
  • I have committed to always providing free firmware updates, for people who wish to upgrade their own chips. Programmed chips are also available in the QRP Labs shop http://shop.qrp-labs.com/firmware 
  • QRP Labs code is not open source (long debate)

I have just finished soldering a QRP Labs receiver. I haven't powered it yet because my Teensy software is not ready. I look forward to try both standard phasing method and 3rd method ssb.
Then a companion exciter module would be nice :-)

Hi Hans :),

Nice. Can't wait to try it :).

Lots of fun :).

Hi Andy, Andy
I can make the firmware change. It only needs a sure answer to these three questions and particularly, someone(s) to test. The coding was not complex and the risk of
unwanted side effects should be very low.

This suggests that you can not make changes to the equipment and programs before the contest!
If something goes wrong, you can skip the competition.
This is my rule, which I have been following for many years.

Re: OT: Linux

I'm one of those that the computer is just supposed to work and by that I
do mean 24/7.  

I find that all interesting having put Linux on strongarm, blackfin, Rpi,  and
assorted wintel(Amd/intel dialed for winder) and older 486 hardware for
several decades.  Then again I run Unix V7 and BSD2.11 on pdp-11.

In fact the last cpu I've used that had a 3c509 is more than 15 years old.
It's in my Dell 486 pizza box with a whopping 32mb of ram. Least it is
for that generation of machines.  I keep that old machine for the fact
that is supports three of the legacy buses.

Last time I had to compile linux for myself was way back more than  22 years
ago and only because the only disti was crappy slackware V.9 and most of
the modern ones were didn't exist then.  Ubuntu has been successful on
all systems I've applied it to, Mint a good second all are off the Debian tree
so finding stuff is fairly painless.  Of course the RedHat tree is also good.

I see no reason with modern distributions to do that.
