Connect iambic cw paddles to your computer

This video will demonstrate how to hook up your iambic paddles to the serial port of your computer in order to use a software cw keyer like MORSE KEYER. You will be able to send and hear morse code with your cw paddles in high fidelity, low latency, and excellent cw timing performance when using as ASIO SOUND CARD with its own ASIO DRIVER. You are also able to use this method at the same time, to send the same morse code audio tones generated by MORSE KEYER to go out over the internet on programs like QSONET, CWCOM, HAMSPHERE, iCW etc....

NOTE: if your computer has a LINE IN audio jack, use that instead of the MIC IN jack. There is much less noise on the LINE IN jack.

NOTE: it may be best match all sample rates between the BEHRINGER, and the MIC or LINE input jack of your computer soundcard and all inputs and outputs, including STEREO MIX of the computer soundcard itself. You can select the sample rates in both the ASIO CONTROL of the BEHRINGER and the windows sound control screen.

set everything listed on both the PLAYBACK and RECORDING tab of the windows control for both the BEHRINGER and your COMPUTER SOUND CARD to the same sample rate

NOTE: using an audio derived cw keying switch circuit, you can also use this setup to key your rig, (need to turn off the sidetone of your rig though) The Behringer has an active - always on - headphone jack- and you can use that audio to go out to the input of an AUDIO DERIVED CW KEYING CIRCUIT, which will then key your rig for you...so at the same time the audio from the BEHRINGER is going out from the LINE OUT JACKS, through a ground loop isolation audio cable to the input of your computer sound card, you can also at the same time, take that same audio out of the BEHRINGER headphone jack and connect it to an audio derived cw keying circuit and key your rig.
You can monitor the audio from your RIG's audio out, to the BEHRINGER LINE IN jacks, by using PEDALBOARD2 to transfer the audio from your BEHRINGER LINE INPUT over to the computer soundcard.

You will then not only hear your own cw audio tones made from MORSE KEYER from the BEHRINGER, but whatever is hooked to the LINE IN jacks of the BEHRINGER, ie, your rigs audio output, you can also hear that too.

You have to be able to monitor the audio coming into the MIC IN or LINE IN jack of your computer's native sound card - you must UNMUTE in the WINDOWS SOUND PROPERTIES, SPEAKERS PROPERTIES, Levels, the MICROPHONE or LINE IN slider...
if you do not have a slider control on this screen, this video tutorial will not work and you will have to search for a modification to force that "slider" to appear.
Please see this picture of the windows sound control for monitoring input by unmuting it and adjusting the volume slider here: http://www.sagebrush.com/mixer_3.png

Here are some examples of audio derived cw keying circuits:

NOTE: Morse Keyer does not have an ASIO CONTROL tab so
you have to use another program that does, so that you can bring
up the Behringer's ASIO CONTROL and set it to "FAST" to lower
the latency as much as possible. There are two lower latency settings than FAST, but on my computer they did not work.
I was able to use PEDALBOARD2 to bring up the ASIO control
for the BEHRINGER: https://screencloud.net/v/w2uC

NOTE: as of 6-13-2016, Behringer no longer has its own ASIO driver: http://www.music-group.com/Categories/Behringer/Computer-Audio/Audio-Interfaces/UCA222/p/P0A31/downloads
