Re: Duplicate emails being received again

Neil Smith G4DBN
 

Hi Hoppy, are there any clues in the mail headers? Timestamp differences? Routing differences? Any other email addresses in there?

I'm only seeing single copies (despite having two large glasses of rather nice red wine).

I wonder if you will see this twice?

I checked, but your subscription seems to be perfectly regular... you joined in December 2016, using the same email address used to send your last message, with display name Shaun Vincent Hopkins... one possible hypothesis is that you subscribed also with a different email address, and the messages sent to this address are then rerouted by your email server to the first address...

Apart from this, I am unable to find a possible cause for the duplication of the messages...

Everyone, I've made some significant corrections to this users guide. The attached pdf file is intended to help me remember, and assist others in configuring the FDM-SW2 software to work with not only the FDM-DUO SDR radio, but also to configure other software at the same time, such as WSJT-X, and FLDIGI. I took a lot of time to ensure the virtual COM ports and virtual audio lines were covered as well. Please review, like Antony did and point out whatever corrections need to be made, or even suggested additional context, etc.

I thought Menu 52 compression only acted on the microphone input rather than the USB audio?

One small point

In SW2/SET select Demod Settings, and bring the Filter Start Frequency down to 50Hz so you don’t attenuate the LF end fo WSJT signal bandwidth.

A couple of other things

I find it better to just use WSJT-X alone, not via FDM-SW2, I guess this is due to my computer being a Mac, I just direct the audio to/fram WSJT and the radio.

Make sure that the radio RX filter is wide too (knob E2)

Also set the low frequency end of the software to 50Hz from its normal value of 200Hz soyoudon’t cut off the RX low end

Have a look at menu 6 AUX VOL and check the levels on the FDM-DUO
receive audio device in case they are too low.  You may need to change
the FDM-DUO audio device level to get the AUX VOL setting to a sensible
value.  With the device at 100%, I get far too much signal into WSJT-X.

If you have set AGC off on the DUO, try changing the gain on knob E1 to
see if that helps adjust the receive audio.

I normally use virtual audio cable looking at the output of the first
virtual audio channel in SW2 rather than looking at the DUO directly.

Check the work done by Andy G4JNT and others on filtering and tx/rx

Re: windows 10 1903 update

 

Hi n2msqrp, K7au

1. Win 10 is better then Win 7 even it is true that Win7 is a very stable Platform; but you miss something.

2. I'm programming for the Flight Simulator and the Elad SW2. This kind of programs are quite difficult to digest. Who encountered difficulties to change to Win10 from Win7 the best advice was and is "get in touch with the Microsoft Forum experts". Any help would need some more precise details about your PC system. You have a problem that other's do not have. There can't be any direct answer resolving your problem.

3. Pls. get in touch with the MS Forum and state with your first question your precise PC data. Avoid unnecessary return questions. A PC is not just doing what we want, still it needs the uman brain and patient.

I'm sure you will resolve. Never say it does not work, knowing that is only depending on us.

Maybe this is not a great help at the moment but believe me; It is.

You need the CAT port for control and PTT, the receive port to send the receive stream from the DO to the PC FDM-DUO audio device and the transmit port to send the tones from WSJT to the FDM-DUO input audio device, so yes, you need all three. I run the RX port on a motherboard USB2 port, and the CAT and TX on a shared hub on another port. Seems to work OK.

Hello,

Recently acquired a FDM-DUO and still in the learning curve with respect to hw and sw. I am puzzled by the number of USB ports. Do I need to connect all three to my pc when when operating WSJT?
Maybe the answer is obvious and somewhere here at the forum or in the doc but I could not find it (quickly).

Re: windows 10 1903 update

 I have precisely the description presented by vk3dnh No audio modulation after 50 ms.  The exact configuration works on Windows 7 Pro 64 Sony VAIO.  I have configured two different machines and have the same outcome.  I suspect it is the resource limitation that Microsoft is describing without the normal message.  I plan to just keep on Win 7 for the Elad FDM-DUO as it is my Winlink Express engine and used daily.

Sincerely,

Re: MaxDbSm meter with FDM-S2

Pardon me for replying to such an old post, but I'd like to make a comment about this virtual S-meter. I just came across this and followed the installation instructions from this post. Had no trouble getting the meter working.

On the Pro side:
It's very pleasing aesthetically. I really like the vintage look! 

Now the Con side:
Unfortunately, the meter uses far more than it's share of pc cpu resources. Within the SW-2 sdr program, I saw my "Total CPU Usage" jump from 20% to roughly 35%. My pc is no slouch and has adequate RAM for the job, so lack of resources aren't the problem.

The meter is a great addition the the SW-2 software but I'd sure like to see the software developer "trim the fat" and make the program use less cpu resources.

I also find that I get Rig Cat failures if all 3 usb's are connected. I leave receive disconnected because of this. possible ground loop on computer usb. works fine with only 2 CAT and TX  73 Mike vk3xz

I find all you need is CAT and TX USB connections for digital.

In fact I can run two Macs, one with CAT & TX connected and using WSJT for digital, the other with RX connected and running W10 & FDM-SW2.

So for FDM-SW2 you only need RX connected, to get the mode, filter, etc and 4 x RX frequency control. Mic provides PTT. And for WSJT you need CAT & TX connected for two way audio and CAT control.
