Re: HELP!!!!!! FDM-DUO & DUO-ART sounds muted #duo-art

Thomas McQuiggan <m7mcqio83ro@...>
 

PAUL JONES (Head if Technical Support for ELAD) contacted me and suggested the problem is more than likely caused by the FDM DUO firmware not being up to date. I’ll update it in the morning and report back 😊


Re: S9 Noise in 40 Meter Band - How Can I Track it Down?

Neil Smith G4DBN
 

Hi Bill, is there any structure to the noise?  Does it have any characteristics which show up in AM mode or FM or SSB? Any periodic changes? Does the noise extend way out of the band? Any difference with an attenuator in line? If you look at the AF spectrum, do you see any peaks/troughs?  Any sign of the PK indicator being hit? Where does the noise start to drop off as you look LF and HF of 7MHz?  Any strong signals anywhere from DC to 55MHz?  Are you close to any TV broadcast stations with 6MHz channel spacing? Could be rusty-bolt mixing product of digital TV?

Any sign of 60Hz or 120Hz components in the noise?  Hae a look at the audio spectrum of the noise in each mode using Spectrum Lab or something to see if it is pure white noise, or has any modulation or periodicity.

Good luck.

Walking the neighborhood with an AM radio didn't immediately point to any obvious source.

Note that I've tested this while on battery power with the main power of my house off. No change. I have noticed that the noise reduces slightly when I orient my magnetic loop antenna horizontally.

Would it be worth buying a cheap portable shortwave radio to try and locate the source. Any other testing ideas? Thank you!

HELP!!!!!! FDM-DUO & DUO-ART sounds muted #duo-art

Thomas McQuiggan <m7mcqio83ro@...>
 

Hi all, I REALLY HOPE that someone can help me with this issue - it's driving me NUTS!!! 

I've connected the FDM DUO to the DUO-ART exactly as shown in the owners manual. I'll attach a photo to show the connections. I'm using Antenna-1 on the radio AND on the amp (there's a G5RV connected, hence the "G5" label on one of the coax leads). 

When I am in "FDM DUO INTERFACE" I get no signal and no audio (or it is extremely muted). If I choose "GENERIC INTERFACE" i get full signal and full audio.

Is there a setting that I'm missing??



Many thanks in anticipation of your help.

Re: elad-gqrx wrapper for gqrx

Hi,


Which kind of system are you using ?

Linux Mint 19.2

But it's working now. I deleted the gqrx config and after that, it starts without errors and Frequency Changing from gqrx to Duo is working now.

Re: Windows 10 SW2 Audio Output

Neil Smith G4DBN
 

That doesn’t sound quite like a driver issue Charlie, the SW2 software should be configured to use the default sound card for output. Doing an upgrade usually messes with the order of the audio devices. If you can get things like Youtube to play audio, then you need to have a close look at the settings in SW2. Sadly, I am a long way from my DUO at present, and using a MacBook, but check the audio tab in Setup and see if you have Use Soundcard Audio Out selected, and the the Main Output Device is the right one for your speakers. If there is more than one option that could be the speakers, try each of them in turn.

Volume gain multiplier should probably be OK set to 1.

Also make sure that the Mute VRX not selected is not ticked.

If everything else is playing OK through the speakers but SW2 is not, open the AF sub window and make sure you are seeing audio there.

The other fault which affects Windows 10 is that Microphone permissions issue, but I don’t think that is what is wrong here.  Have a look back through the forum posts about Permissions just to be sure.

Good luck.

When I boot SW2 all controls operate normally. I can do any operation associated with the DUO and see the proper results.

But I CAN'T get the FDM DUO sound to be output through the computer speakers. I only hear the sound through the FDM DUO internal speaker, or the auxiliary and headphone outlets.

Any help out there? I hear a lot of talk  about Windows 10 driver problems, but so far am unable to find verifiable info on how to resolve this.

CONNECTIND DUO-ART TO YAESU FT-817/818

A link would be great.

Re: elad-gqrx wrapper for gqrx

Giovanni Franza
 

Hi Heinz-Juergen,
baud rate on the DUO is not important, since the frequency is set through the I/Q port and not CAT.

It seems that the problem could be remote control, but if elad-gqrx is not able to talk with gqrx it stops and exits.
Is it possible that the remote port is not 7356 ?
Or that some system settings disable connections ( Mac system asks to enable it in firewall settings ) ?
Which kind of system are you using ?

To recover configuration; start gqrx itself and save configuration (not important which one) or cancel
the file .config/gqrx/default.conf in the home folder of the user that launches elad-gqrx
than relaunch elad-gqrx

If you are unsucessful to keep frequency working try to launch elad-gqrx using GQRX_DEBUG and send me in
private mail what appears on the screen.

Hope this helps,

Giovanni - HB9EIK

Re: The inner workings of the DUOr SW2 AGC

I correct myself : the AGC on the FDM-DUOr is made at audio level, after the demodulation, so the IQ recording is not affected.

Subject: [EladSDR] The inner workings of the DUOr SW2 AGC

Hello group,

Can the DUO/DUOr AGC affect an IQ recording?
Some low cost SDR:s have a feedback loop with gain in their AD conversion process, but this does not apply for the DUO7DUOr platform, for sure.
I am doing a lot of processing of IQ files for NDB hunting on LF/MF and I am keen to know what my ideal settings should be.
Even though "gain compression" should be impossible in an IQ file; I've come across a phenomenon in my data that I like to understand as best as I can.

All the best!

Re: elad-gqrx wrapper for gqrx

Heinz-Juergen Kronemeyer
 

Hi Giovanni,

I played a little bit with elad-gqrx and my FDM DUO. It starts and set the Frequency to 14.200. Communication seams to work at that point. Waterfall and Audio is working but trying to set the Frequency from gqrx to the DUO, it did not change the Frequency at the DUO. Baud Rate at the DUO is set to 57600. Starting gqrx with ./elad-gqrx export GQRX_DEBUG=1 crashed gqrx. It shows a wide out of Range Frequency (above 4 GHz) and then gqrx freeze.

Heinz-Juergen  DO1YHJ
