Re: [Elecraft] K3 sound recording

[ab2tc]

Hi,

An audio splitters is just a plain T junction and can not be used in
reverse. That will probably just produce lots of distortion as the the low
impedance audio sources are fighting each other. What K7HP is suggesting,
however, using a pair of resistors to form a summing junction from the two
outputs should work but will of course involve a little bit of home brewing.

Re: [Elecraft] K3 sound recording

[Richard Ferch]

Unless I am missing something in your description, the only hardware you
need is a single stereo patch cable (one with 3.5 mm stereo plugs on both
ends) from the stereo Line Out jack on the K3 to the stereo Line In jack on
a standard 2-channel sound card. If your sound card has only a mono input,
use a different sound card (one with stereo inputs). In the Windows setup
for the sound card, make sure it is configured for two channels.

The main RX audio will be recorded in the left channel and the subRX audio
will be recorded in the right channel of the stereo recording.
Transmit monitor audio will appear in both channels. On playback through
headphones, you will hear the main RX in your left ear and the subRX in
your right ear.

For dual-RX RTTY with the identical hardware, run two separate copies of
your RTTY program(s), one copy configured to use the left channel of the
sound card (for the main RX) and the other copy configured to use the right
channel of the same sound card (for the subRX).

73,
Rich VE3KI

Re: [Elecraft] K3 sound recording

[Cady, Fred]

Have a look at the sound card's Microphone properties and then click Advanced.  
You will probably  be able to select a two channel input if a one channel input 
is currently selected.

I routinely do this...  Works great for me...  I use a different
program called i-sound.  It has a small footprint and works well...

Don't see why not.

Here's the question: For my K3, if I connect a line between the K3 
LINE OUT and the PC's LINE IN, will I be able to record (using 
software such as Audacity) all audio present in my K3 speaker or

[Elecraft] K3 sound recording

[Mike Goldstein]

I've been asked to do a workshop on contesting techniques next 
autumn, so I'm working on an audio/visual presentation.


Here's the question: For my K3, if I connect a line between the K3 
LINE OUT and the PC's LINE IN, will I be able to record 
(using  software such as Audacity) all audio present in my K3 speaker 
or headphones?  I want to record CW and

SSB contest QSOs, to illustrate my contesting techniques.

Thanks, Mike Goldstein VE3GFN
