Oh well. If not, I still have my 6500 to play with!

Does the "digital" in DAX imply that DAX will only work in digital modes? I was wondering if it could potentially be used in SSB/AM to connect an audio processing program's output directly as the tx audio source.

Thanks & 73,

It's a virtual distribution of the 8 Audio In- and Output of the 8 slices receivers.
Remember: the 6700 will have in future 8 separate receiver. Now you can manage 8x audio Input and 8x audio output channels. So you can run 8 different software tools to do something with the audio. Only one of the choices is Digital Modes.
It's up to you want you do with each audio channel.

This work (DAX) will done digital in your PC.

Hope i am right

Will the audio be "streamed" over the local network so that we can work digital modes from a remote computer on our local network?

If not, when is that capability planned?

Yes, Ed, you can stream to a local PC on the LAN. In fact, you can run DAX on multiple PCs and send streams out of the radio to each PC.

The TX button you see in the DAX video selects which PC will be the transmit source for that DAX channel. When you go to transmit, the radio determines which slice is selected for TX, just as it does today, then if it is DAX the radio determines which PC running DAX will send the TX audio. So the implementation makes the TX button exclusive within a DAX channel. For example, if you select DAX TX on your first PC for DAX channel 1, then go to your second PC and select tX for DAX channel 1, the TX will uncheck on the first PC.

Thanks, Steve! Pretty cool...that will be one of the first things that I try when the beta software is available.

Steve one of my concerns is I want to pass audio transmit and recieve via a blue tooth head set . Can i do this using my pc the radio is connected to? if so is there some instuctions available. the video above was great and very simple.

Thanks for providing the UTube instructional video...interesting.
Looking forward to streaming to other PC's on the LAN here.

Merry Christmas

.... run DAX on multiple PCs?
Is DAX a standalone tool or a part of SmartSDR?

It is installed with SmartSDR but it is a standalone client application, like Smart CAT.

Very good video, I've saved it so I can use it while setting up.
I suspect I will be referring to it VERY often.

This is VERY new to me so sorry for my ignorance on SDR & DAX.

I'm pretty sure I know the answers to the next two questions but...
1. Can DAX be used with my Flex5K?
and
2. As I use the same computer for Flex5K and 6K. (Neil built-very hot computer)

I'm sure that both VAC and DAX can co-exist on the same computer?
While I don't expect to be using both at the exact same time, I'm sure I will be jumping back and forth while the 6K still is in the Roadmap development period.

as always, pse & tu de W9OL

I'm guessing yes to both, but am not positive. If DAX sets up its own "audio cables" it seems any app should be able to use them. Since it is not explicitly part of SSDR, I think it will work like CAT.

I use WSJT-X for JT65 and JT9 that requires "split" mode. I have implemented this in the past on my 6700 (with the SignalLink) by opening two slices (and two panadapters). I use Slice A for receive and Slice B for transmit.

Am I correct in assuming with DAX, I will have to open two channels, one for slice A and the second for slice B?

Thanks!

WOW!
A couple of questions...

1) The latter part of the video talks about setting the sample rate to 48 kHz, although DAX uses 24 kHz. Is there anything to be gained by setting to 24 kHz? I can't imagine that our low-rate digital modes need the full range.

2) (For K0KC) I'm also using WSJT-X, but without split. The +2 kHz button toggles me between JT65 and JT9 "subbands" effectively, and the TX audio settings in the Flex (6500 here) allow the full range of tones. Am I missing a pro tip?

3) I want to call in from work to hover over the Flex site for the DAX beta release. Can someone write me a note?

73 & Happy New Year, Flexers...

Maybe this will work...

To whom it may concern:
I examined George J Molnar and have confined him to his home due to Acute RF Deficiency Syndrome (ARDS). I am recommending that he undergo uninterrupted RF replenishment therapy for a minimum of three days at which time he will need to be re-evaluated.
Sincerely,

Doctor C. Mor Flex

The answer to #1 is that there is not a selection for 24KHz and there is nothing to be gained. It is easy to divide 48KHz by 2 since it is a binary number.

George,

I certainly would not call myself a "pro", but I can tell you if you set-up your transceiver for "split", you can see JT65 and JT9 signals simultaneously and move between the modes with a simple double-click of the mouse. Check the documentation that Joe Taylor provided and if you need additional "hand-holding", contact me directly via email.

Another quickie question...
Will the DAX stream levels change with the individual slice audio level (speaker icon) and AGC settings? Or is the pickup point for the stream before those controls? I usually run digital with the AGC off, but that makes for some uncomfortable listening if I put it on the speaker.

Guess I'll know soon enough - just daydreaming in the office!

I am curious as to whether I will have to listen to the psk31 while it is decoding while I am simultaneously checking the SSB traffic on another slice. I will know the answer tonight.

Hi George ...The video seems to indicate the DAX stream level adjusted on the DAX audio control panel were independent of the slice controls? Soon....

You can mute the audio without affecting the DAX stream. They are totally independent.

It works! If the panadapter is to be believed (and of course it is!), digital mode transmission is notably cleaner.

Levels to tweak and such, but so far - so good.

Thanks!!!!!!!!
