Fwd: sending computer morse?

Greg,

A good friend of mine K1BX helps build these interface units. Set the K1 to straight key mode and hook up this keyer to your computer. Can't help you with the software but there's got to be some freeware logging programs out there that can key this.

Re: Fwd: sending computer morse?

Most of the free and non-free programs have support. Look for the
"WinKey" setting.

You can do it cheaper by building a simple transistor circuit that allows you computer to key the radio via the computer's RS232 serial port. Not quite as good as a Winkeyer, but gets you on air very quickly so you can have a play.

Re: Fwd: sending computer morse?

Keying via DTR or RTS will work with the simple transistor circuit, but
it is subject to timing problems created by the operating system. There
is no way for an application to directly control a port, so the
application has to pass the request to the operating system and then the
operating system will control the port when it deems appropriate. That
may be OK at slow CW speeds, but the timing becomes more critical at
higher speeds. Enter the WinKeyer to solve that problem.

Re: Fwd: sending computer morse?

Since you are talking about "operating systems" and since most ham software
is written for Windows, a much less expensive solution is to just turn off
Windows sound generation. When Windows generates sounds, the CPU first shuts
off the I/O ports, which causes CW stutter, generates the sounds and then
returns the I/O port to normal operation. Eliminating that sound generation
removes that 'stutter' generated by serial (or I/O ports) port. I have been
using audio generated CW driving a simple audio detector, to key my
transmitters for about 30 years and running in excess of 60 wpm, without any
serial port generated stutter. And it cost a LOT less than purchasing
outboard keyers!

Don & The List,

There is a free program called "The Mill" but it requires that you
boot your computer in DOS and it will control the DB9 serial connector.

The Mill is a learning tool and it will teach you code up to about 40
WPM. In the particular application I think you want, it will print
what you type on the screen and it changes colors as it goes out to
your transmitter if you should type faster than the speed you set.

http://home.comcast.net/~w4fok/

This link will take you to the home page of "THE MILL."

In reply to this post by Don Wilhelm-4

On the other hand, for any wanting to quickly or cheaply get on the air that way
it might be worth a try. I made a circuit similar to this one just now provided
by google:

http://i1-linux.softpedia-static.com/screenshots/Cwdaemon_2.jpg

(PTT portion not needed.) I've had no linux timing issues when taking part in
contests. My top speed in contests is upper 20s to 30 wpm. Beyond that, my
ears can't distinguish much - sure wish they could - so can't speak to those speeds!

Re: Fwd: sending computer morse?

In reply to this post by Don Wilhelm-4

It depends a lot on what your computer is doing. For years I used DTR keying with N1MM and
a slow computer, and I couldn't understand why people claimed that there were problems
with this. But I never operate 'assisted' by Internet connections, clusters, etc. in
contests. So that may be the reason it worked as well as it did.

Anyway I recently got a Winkey USB, and was surprised at how much better the
computer-generated CW sounded! Also, the Winkey offers PTT switching that is smoother and
faster than the semi-QSK in the K3.

The one downside (for me) is that I absolutely /hate/ the stand-alone keyer function. I
just cannot send with it without making lots of errors, despite trying numerous settings
of the paddle sensing function.

I am used to mode B iambic keying, and I set all my keyers for that mode. The best one for
me is the Idiom Press Logikey K3. It is better than the internal K3 keyer, which is better
than the Winkey. So I still use the Logikey for my hand sending.

Re: Fwd: sending computer morse?

Vic,

Each to his own style, but the WinKeyer also provides Ultimatic mode
which is the only mode I can use with a dual lever paddle. With a
single lever, it does not matter.

That is great, but how do you "boot your computer in DOS" if you are
running Win XP or higher.
Did you wisely save a copy of DOS 6.2 just for such occasions?

Umm... doesn't it kind of defeat the purpose of running DOS in a virtualised environment under Windows kind of defeat the purpose of running MSDOS in the first place, which was to avoid the real-time timing issues that come with Windows?

Re: Fwd: sending computer Morse?

DOSBox is capable of timing-compatible implementation of the serial ports,
and can run older hardware and software dependent on such;

http://www.dosbox.com/wiki/Dosbox.conf#.5Bserial.5D

[serial]

serialX = device [parameter:value]
device can be: dummy | modem | nullmodem | directserial parameter is: irq
value is: 1. for directserial: realport (required), rxdelay (optional).

Re: Fwd: sending computer Morse?

There's also FreeDOS, which run's on the bare machine. E.g. it is
*not* a window inside Windows 7.

So you don't need to have a saved copy of MSDOS 6.2.

Re: Fwd: sending computer Morse?

Very good yes, a few choices available. Interesting reading;

There's also FreeDOS, which run's on the bare machine. E.g. it is
*not* a window inside Windows 7.

So you don't need to have a saved copy of MSDOS 6.2.

Agree - for contesting I've been using Win-test, keying it with RTS,
even through a USB to serial adapter for the configured CAT com port.

Usually I key in 28-35 WPM, and with sound OFF on the computer, it works
fine.

Only rarely it messes up the timing of the CW code, but in practice it
works like a charm.

Done so on my K2, and lately setting the same up on my Kx3

Brilliant Tom, run services.msc and turn Windows Audio (off) ok.
