K3 Sub receiver

Hello all

I hope this is not a dumb question .......... I have a K3 (not S) which has
the sub receiver and has been updated with the KIO3B.

I have main RX audio available on the USB port.

Can I have the sub RX audio on the USB port - and if so, how is it done ?

Many thanks

John G4ZTR

Re: K3 Sub receiver

Sub receiver audio is available on the *RIGHT CHANNEL* of USB Audio
CODEC - just as it is available on the *RING* of the LINE OUT jack
and RING of the headphones jack.

Wrong question. It's already there. The USB audio is stereo. The main RX is on the left channel and the sub is on the right.

Question is what do you want to do with the sub RX audio?

I.e., for RTTY you'd need to run a separate instance if MMTTY and set input from RTTY channel.

Re: K3 Sub receiver

Maybe not so wrong. The sub audio is on the right channel of the USB audio but you may have to go into the Windows Sound set up and the USB audio Codec to be a 2, channel, 48000 Hz device. Windows sometimes sets this to be a single channel device.

Cheers and 73,

Bill, Joe and Fred

Thanks for your quick replies. It certainly WAS the correct question to ask.

Fred has put his finger on the problem; my Windows settings had defaulted to
single channel audio. My question turns into "how do I get Spectran to look
at the other channel" but that's not an Elecraft question.

Why am I interested in the audio from the second receiver ? This goes back
to a problem with my K3 which on 28MHz has a large number of receiver
birdies - I posted about this a couple of weeks ago. The situation has been
improved by tightening all the panel screws absolutely as hard as I can. I'm
no weakling but it seems that I was being a bit too cautious. But some
birdies remain, and I noticed that they are at different levels and
different frequencies on the sub. So I was making a careful check and
listing the frequencies and signal level, using Spectran. But so far, only
on the main rx. Hence my question.

Re: K3 Sub receiver

In reply to this post by Nr4c

Being able to easily run both main and sub in RTTY is why I
still use cocoaModem on my Macintosh. (It suffered from serious
incompatibility with a new version of the OS a few versions ago.
I still have a backlevel machine with full functionality.)

It has a dual RTTY mode with two decode windows, one for the
main receiver and one for the sub, like using stereo headphones
for CW of SSB. It is the only program I know of, for any
platform, that does this.

MixW has a dual channel decode mode. N1MM Logger+, and WiteLog will
both open two RTTY decode windows (using two copies of MMTTY), DXLab
Suite will open three RTTY decode Windows (using MMTTY, 2Tone and the
K3 Decoder or a hardware TU) which can be assigned to either receiver,
and Logger32 can open two decode windows (one for each receiver).

Dual channel decode is quite common in the Windows world.
