Re: Using the FlexRadio IQ channel with WSJT-X and MAP65 #Q65 #map65 #FlexRadio #Windows10

1. WSJT-X accepts the IQ stream it does create almost similar FT8 results as the base band.

3.1 I am using an H/V Yagi with symmetrical horizontal and vertical 10 by 10 elements on the same boom.
3.2 Flex 6600 has 2 antenna inputs with a 16 bit A/D converters on each antenna input creating a base band and an IQ data stream. Both ADC operate from the same clock.
3.3 Merging the 2 data streams into an interleaved single stream appears to me as a simple software job that can be done by WSJT-X or Flex.

Hi Amos,

1) no WSJT-X does not currently understand I/Q data, you will get some decodes by selection one of the I or Q channels but that is sub-optimal and you should use a base band audio stream of up to 5 kHz bandwidth as input.

2) Q65 is no different, the front end audio processing in WSJT-X is the same for all modes.

3) I have explained this before to you, for polarization diversity mode
MAP65 requires a pair of synchronized I/Q data streams. That can only happen if the two data sources are received from co-located aerials (receiving the same wave-front), use a pair of ADCs sharing a common clock, and the two data streams are interleaved so that MAP65 can process each sample together with its partner from the other ADC (other polarization). As far as I know none of this is possible using a Flex Radio multi-slice SDR since the I/Q data sources are independent (think Humpty Dumpty https://en.wikipedia.org/wiki/Humpty_Dumpty, once broken some things cannot be easily reassembled!)

Re: MAP65 Installation #map65

Hi Ian,

the "Decode" button should turn cyan for a second or more at around seconds 51 and 57 of the minute (depends on the modes selected). The correct timing of the decoder activity also depends on the correct sample rates being selected, are you you using the default 96000 rate, and does that match the rate that Linrad is sending I/Q data at? Do you have the MAP65 Xpol setting set correctly for your system?

Hi Ian,

I doubt Edge is using UDP on any port so that is not an issue, TCP and
UDP are separate.

The only requirement on port numbers is that whatever you set in the
MAP65 settings for the port to listen on (default is 50004) must be the
same port you have Linrad sending on. Whichever port being used will
have to be opened on the Windows machine firewall for incoming UDP
traffic to MAP65.

Ephemeral ports are granted to processes on some internal basis by the
operating system, a restart should always sort out any issues where the
o/s has granted a port you want to use to another process.

So I am not sure what is happening. Other MAP65 users are able to use
Linrad to feed I/Q data to MAP65 so it would appear to be something
specific to your machine.

Hi Bob,

so I can see what is happening please run the following test.

Put the attached file into your WSJT-X configuration files directory (on MS Windows that is the same as the log files directory "Menu->Open log directory"), restart WSJT-X, carry out a *minimal* test that demonstrates the issue, then quit WSJT-X. It will have created a file called WSJT-X_RigControl.log on your Desktop. Send me (g4wjs <at> classdesign <dot> com) the log file for analysis please?

Once you have sent the log file you can delete the log file and log configuration file to return to normal operation.

Hi Jeremy,

currently WSJT-X resets the CAT connection when you change settings and exit the settings dialog. We recommend setting up a separate configuration for FT8 DXpedition Hound mode ("Menu->Configurations"), then add the current published working frequencies ("Settings->Frequencies") of DXpedition stations using FT8 DXpedition Fox Mode. That will allow quick QSYs to their frequencies in the correct mode. Once set up like this it becomes much easier to track down the band they are active on where you have propagation.

OM,

is it possible that another process is also listening for UDP datagrams
on port 50004? As that is in the ephemeral port number range on MS

Correct, Bill.  So, what do you suggest that will correctly configure the xmit audio?  I actually was trying to keep it simple by not going thru all the other options, which I've tried; i.e., an apples-to-apples configuration comparison.  Problem is that this was working fine a few weeks ago. 

So, the real question is:"How is WSJT-X V2.5.0 handling audio differently than two other (similar) applications that successfully transmit audio (where WSJT-X does not)?"
