K3S Computer Audio Question with Sub RX installed

When I get the SubRx will it be possible to monitor two different
frequencies/bands AND have the audio separate on the computer? I'd like to
be able to monitor two different bands for digital traffic.

I just can't imagine how that will work. I'm pretty sure I can listen to
different antennas (diversity mode) but not sure about different bands.

Thanks in advance.

Re: K3S Computer Audio Question with Sub RX installed

Yes. You will then have to separate receivers in the K3, each with its own antenna. They can go to any band they wish, independently. The only limitation is the need for separate antennas.

As an example, I have been monitoring VP8SGI on both 20 and 17meters simultaneously. 20m in my left ear, 17m in the right. It is an exercise left up to the user to figure out how to separate the two in your head…

It works quite well.

Re: K3S Computer Audio Question with Sub RX installed

So how does the audio separate on the computer?

My 2nd receiver is -only- used for monitoring 6M and has a dedicated 6M
omni antenna connected to it's input to listen for band openings.

The audio is in stereo, main on left channel and sub on right channel.
Computer Soundcards are all stereo. Why do you think it would be a problem
keeping the audio streams separate?

Jerry,

One is on one channel of the headphones, the other is on the 2nd channel
in the headphones,
That is not a problem for the computer soundcard with a stereo input,
but it may be a problem for the human brain.

I used to have VHF pumped into one ear and UHF in the other while flying
helicopters... Sometimes, there'd be FM from my Infantry brothers, too.

You'd be awed what the human brain can learn to do. :)

You need a way to separately decode both the left and right
audio channels. I use cocoaModem on the Mac to decode two RTTY
signals. Usually that's the DX and the pileup. I think there are
also some windows programs which will do this dual decode. Are
there any Linux programs which will do it? I can't find out how
to do it with fldigi.

For maximum flexibility, you will need two sound cards assigned
to two separate programs.

Re: K3S Computer Audio Question with Sub RX installed

In reply to this post by Jerry Moore

Fldigi versions since 3.22.06 have the capability of decoding from
either the left or the right channel of a sound card. You can use a
command-line argument to tell fldigi which configuration files to use
You would run two instances of fldigi with different configuration
files, one configured to use the left channel of a sound card on receive
and the other configured to use the right channel of the same sound
card. With this kind of setup there is no need for two sound cards.

Programs like MMTTY that store their configuration information in a file
in the program directory can also be used for dual receive. Simply set
up two separate copies of the program in different directories, and then
configure them to use the left and right channels of the sound card
respectively.

For basic dual RX receive that's all you need. Rig control and transmit
capability add complications that depend on the specific hardware and
software you are using. Note that if you want to be able to transmit on
the VFO B frequency, both receivers must be in the same band. This is a
transceiver limitation - the K3/K3S will not do cross-band transmit.

Re: K3S Computer Audio Question with Sub RX installed

Thanks Richard. I had not thought of running two copies, as that
is an "unnatural act" for a Mac. The Mac will do it, but it
takes two copies of the program (so the Mac thinks they are
different programs).

Running two copies also solves the problem of wanting to operate
JT modes while copying a W1AW RTTY builtin on an different band.

Re: K3S Computer Audio Question with Sub RX installed

In reply to this post by Richard Ferch

To expand on Rich's comment:

The comments thus far focus in the benefit of receiving two frequencies
simultaneously. Another benefit for digital modes is being able to receive
THE SAME signal (frequency) but through two antennas with two receivers, two
digital programs (can be the same program twice or dissimilar apps), two
decoder filters - improving your chance of solid signal decoding under
marginal conditions. See the K3 instructions on Diversity and Link AtoB for
information on how to automatically track vfoA's frequency on vofB while
tuning.
