Is DAX IQ muted on transmit

As a potential 6500 purchaser I am holding off until WAN remote is available. However, have a use for DAX IQ - hence the question. I have searched the forum & RTFM but cannot find an answer. Many thanks.

Paul, it would be interesting to know what use you have for the I/Q stream,
as it is for receiving purposes only, no need to mute it on transmit.

You must have overlooked it in the manual, as the DAX I/Q stream is described
in extenso on pages 120 ff.

Also see Steve N5AC's answer here:
 https://community.flexradio.com/flexradio/topics/question-for-flex-6k-users-doing-jt65-or-jt9 )
I use a 48k or 192k sample rate for CW Skimmer with SDRBridge, but that is one of the few
programs, which can use the I/Q output. fldigi, HRD, WSJTX are using the DAX audio stream.

If you want to experiment with I/Q transmissions, HDSDR is the program for you:

Hi Alex, yes I realise the DAX IQ stream is for RX only but I am keen to know if it is interrupted (muted) during transmit.

I run a public WebSDR and the server requires an IQ stream. Typically WebSDR's use low budget SDR's. Currently I am using an SDRIQ as the source. Whilst this gives many improvements over (say) a Softrock, it occurs to me that if/when I finally buy a 6500, I should be able to utilise DAX IQ. However, it will only be viable if the stream is continuous (eg. if I were to be transmitting on another band or frequency).

Hope this clarifies things. Cheers.

Only if FDX is selected in SmartSDR.

Thank you for clarifying your question, Paul :-)

I also run a SDRIQ here, and after some years I'm glad I still have it. It's almost as
good as my ELAD FDM-S2 and - together with CW Skimmer - unbeatable as a CW
monitor. I would keep it running in parallel to the Flex 6k5 and keep the antennas
wide enough apart so the SDRIQ does not get overloaded. I all depends on your
transmitting power, of course. I typically run 10 watts out in my shack and my
SDR and TRX antennas are only 3 meters apart! (QRP only here, out of necessity)

I really can't tell you anything about the I/Q stream keeping on whilst transmitting,
as I haven't tried it with my Flex 6k5 yet. As Ria N2RJ has posted, FDX (full duplex)
is the way to go.

Can you post the url of your websdr?

No problem Alex. I agree the SDRIQ is a definite "keeper".I've been using it since they first came onto the market - it has never missed a beat despite being on practically 24/7.

Interestingly, I also have an Elad (FDM duo) which is a great little transceiver - a flex seems to be the natural progression.

The Websdr is currently top-band only & uk based, so most activity is post dusk our end. I do sometimes see reports from users having heard the states (early our am). The antenna is a full wave 160m loop so it hears reasonably well. The URL is:

Yes and no. The 6300 can do full duplex under certain circumstances....

If 1) you are using a different antenna for receive than for transmit, AND 2) there is sufficient isolation between the antennas. AND 3) you are sufficiently removed from the transmit frequency that your receive frequency is not overloaded by the transmitter.

This is for receive and transmit slices. I don't know about the whole RX IQ path.

Right, as Ria said, 4) You must activate the FDX button on the bottom left of the SSDR window.  I forgot to mention that.

Thanks for the helpful comments everyone. It seems that I should be able to use DAXIQ with FDX enabled. Now all I need before I buy is WAN remote ;)

Don't let WAN Remote delay your purchase. There are plenty of users who are enjoying remote with a vpn connection either with OpenVPN in their routers, or SoftEther on their shack computer or an inexpensive Raspberry Pi! Come on in! The water's fine!

Thanks for the encouragement Ken. I currently run WAN remote over VPN & SSH with my existing rig, so already have "the bug".

The main reason to wait for V2 is to cut costs. I dont really want to buy a rig now only to pay a supplement (in a few weeks/months/years ??!!) to get WAN. I realize it's a relatively small % of the initial outlay, but I'm patient. Cheers.
