Neil what transverters are you using and how much power on 10ghz to make that QSO?  Any info info about your station would be appreciated!

I interface WSJT-X to audio sources within the hardware radio and not using virtual audio cables between the output of SW2 and WSJT-X.   SW2 adds too much delay for WSJT-X to work properly.   I still use SW2 as a wideband pan adapter to look for digital signals.  The SW2 waterfall can be configured to be very sensitive to weak signals.   Nearly as sensitive as the WSJT-X waterfall.

I am also using the FDM-DUO on 6M FT8 and 40m FT8.   I will soon give the FDM a try on 6M EME.   I believe it will do very well.

I am experiencing a problem with the new SW2 beta.   After a few hours of operation the delay in SW2 is significant.  It feels like a memory leak causing the buffer ti grow.   If I stop / restart SW2, the delay is normal again but starts growing.

The FDM-DUO is my first "modern" radio.   I am doing more CW now.  What a pleasure finding and resolving weak CW in a 300 Hz BW.  What a pleasure!

I think I might own a third FDM-DUO to replace the clock radio on my night stand!

Hello Ian, the group,

 

You address several questions.

  1. The usb resources. I’ve got that problem too. I solved it using an external USB hub. But you have to find one that is HF resistant, specifically to the 7 MHz. I found the Atolla USB 3.0 hub with 4 USB ports and 1 smartcharging port and the aluminium case. I use 3 ports for the DUO and the 4th to command my PA.

https://www.amazon.co.uk/Charging-Aluminum-Individual-Detachable-Extension-USB-Hub-AC-adapter/dp/B07DPNYG8L/ref=sr_1_1?dchild=1&keywords=usb+hub+3.0+atolla&qid=1587674960&sr=8-1

  1. To have a good CAT dialog, you must chose “ELAD FDM DUO” within the wsjt-x settings, and not Kenwood TS-480. Otherwise, no stable TX…
  2. Sound cards : for TXing I use the DUO sound card FDM-DUO Audio V1.04. For receiving, I use the FDM-SW2 software and a  Virtual Audio Cable. But I’m sure you could use the audio of the DUO sound card FDM-DUO Audio V1.04 in the stand alone mode. Don’t forget to turn the bandwidth to 50-4000 Hz. Using the FDM-SW2, for the digital modes I use RX1 and for SSB RX2, RX3, RX4.
  3. Sound cards bis : I set all the sound cards at 48 KHz sampling and 16 bits. You don’t need any stereo mixer. Take care to disable any sound enhancement. You should not need stereo. If you cannot select mono, the “mono” channel is the left one.

 

I could give more detailed settings, if required. Let me know. I’m an addict to digital modes, and I’m using the DUO for all of them. I still have to start with SSTV. For digital no wsjt-x, I use HRD + DM780. With HRD you have to use the Kenwood TS-480 emulation as there is no Elad FDM duo choice. It’s well working.

 

Let me know if you need more detailed info.

Re: RE : [EladSDR] elad duo wsjtx and new windows 10 pc i5, 8gb ram dell

 

Thanx Alain

i was talking to a friend on dmr and that’s what we were talking about, so I removed the hub and “hey presto”. It worked

i now remember having the same problem with a similar hub

i now have the duo plugged in to different USB ports and the 2 hubs plugged in to others

i have 10 USB ports 4 of which are 3.0 which il use for other items

duo is currently plugged into 3usb 2.0 and working well

il have a look at your link,,,as I like to keep my duo as far away from pc as possible

So a hub will offer me an extension of sorts

thanx and regards

Re: DRM #fdm-sw2

Back in February, Radio Öömrang used DRM for one of its annual transmissions to North America using a transmitter at Issoudun in France. It was well received on the east coast. Sometimes Radio Romania International and other broadcasters using DRM can be heard here. And WINB uses DRM pretty well daily.

Re: Elad Update and SW2 goodies

Ted Pater
 

Tested ver 3.033 FDM-SW2 with T-Mate2 controller on WIN10Pro-64 in the dual channels mode.
Second channel on the dual monitor setup looks very impressive, listening to the different bands the same time.
Don't like:
1. T-Mate2 controls only  Ch1 radio.  
2. Radio RX4 on Ch2 has no audio
2. I use the Griffin Power Mate USB knob to control the PC audio. It only works if I click on the desktop,  outside the opened FDM-SW2 program /focus change?/.  If the program window is maximized, there is no open space on the desktop to clock, and the Griffin knob is useless.  This does not happen with the other SDR software I use.

Yes, that's true, but if you want one in your own shack as a DRM
receiver you have to buy one :-)

There are a couple of KiwiSDRs in India run by TWR. Check the
list at http://kiwisdr.com/public/

Since sdr.hu went "ham only" it's not so up-to-date.

Re: Thinking into the next step ...

Paul Jones
 

 

There are 3 questions related to Elad’s FDM program:

3.Does it have a IF bandwidth of 10 MHz or more so someone can listen to more than 2 FM radio stations same time ? Ideal of news recording .

The S2 has a Max Bandwidth of 6.144Mhz

4.Does it have signal history feature similar to SDR console or SDruno’s PWR/SNR to CSV?

No, but if you record the IQ then as you replay or watch live you can see the SNR if you have it enabled and displayed

5.DRM Mode supports listening  all the available channels as DReaM? 

 Drm will decode the main audio channel and the sub channels also the Text channel, or you Can feed out to Dream if you wish

Re: DRM decoder on FDM program

Chris Mackerell
 

Assuming you are using the Elad FDM-SW2 software:

1. Tune to DRM signal
2. Select DRM from the mode drop-down menu
3. Listen

This, of course, requires the DRM signal to be strong enough
to decode.

If you have selected DRM mode, you should see two extra little
buttons to the left of the mode/bandwidth options.

The top one, which looks like a spreadsheet symbol, is supposed
to display a schedule of DRM broadcasts. Mine is blank, and I
can't find where to change the URL it uses.

The bottom one, labelled "Info", will open a pop-up showing
the DRM signal state, and the multiple streams available
(if any)

Cheers, Chris

Re: DRM #fdm-sw2

Chris Mackerell
 

If you want to decode the new modes the best option at the moment
is to buy your own KiwiSDR. The KiwiSDR software decodes the
new modes.

There are some newer "consumer" radios that decode the new
modes for India, but they are not very good for radios
otherwise.

The Dream software does not yet decode the new modes. A very
small number of people have managed to patch & compile the
modified source code. I have tried myself several times on Windows 10,
but never with total success :-(

Re: DRM decoder on FDM program

Hey Dennis

It’s as simple as tuning to the signal, switching to DRM modem instead of SSB, CW etc, waiting a few seconds for the signal to sync and buffer and you should be hearing the audio.

You can find a schedule of transmissions at the DRM website.

Regarding DRM reception , as most users knoe there are new DRM modes coming up for AM - FM
India - China - USA? I would be willing to pay for the latest decoder ( all modes ) to be incorporated in SW2 ..
perhaps there will an option to come when the Duo X go into production ( I hope )
Catching DX DRM from far of europe would in what ever DRM mode be a bonus..
More power to Elad if this happens ..this one radio never to be  parted with.. ( FDM-Duo)
It still amazes me on it's capabilities.. DRM hunter looking  to the future..

Everyone stay safe ...see  you all on the other side...of this ...

Thanks Chris. Many years ago I wrote a description how to use the AOR AR7030 without modification for DRM reception. Importunely I can't find it anymore.

It's one of the ones that SAT-Service Schneider offered back when DRM was
new. It has the IF module built-in and wide filter for DRM.
It is still my best receiver for DRM, though my un-modified AOR AR-7030 comes
close.

I haven't found the decoder in the Elad software very good. If I'm using my DUOr I
tend to run Dream from the IF output of the software. I seem to get better
decoding that way, and can create log files etc

Cheers, Chris

Is that with or without modification Chris ?
