Re: Fine tuning ... off ...

Neil Smith G4DBN
 

Have you tried the calibration procedure in section 2.1.7 of the SW2 manual?  Sorry I don't have an S2, but it looks like that might be the correct approach.

I suggest you zoom in to maximum so you can see the peak very clearly!  On my version, the menu item is greyed out, as I am using a DUO, but it is called "Frequency Alignement", not "Frequency Calibration" as it says in the manual.

Re: Programming HC05 for BLUEDUO

Thanks Giovanni for your response.  I went through the process again, and I think I'm doing everything right.  I'm new to the Pi, and I'm probably doing something wrong.

I notice that the programming diagram shows the HC05 KEY line connected to Pi pin 17,  A shot in the video shows it connected to pin 11.  Pin 17 would seem to be correct to provide a HI to the Key line.

Got any other ideas?  Thanks again.

I use a multi-track recorder called Reaper to record DX radio from two Elads and four Sony XDR receivers. If I want, I can do this simultaneously on the eight channels from the Elads and four fom the Sonys. Generally, however, on good DX conditions I have 2x6 MHz RF recording ongoing without real-time audio monitoring and pan the audio from my four Sonys to my headphones (100%L, 33%L, 33%R, 100%R).
 
For the Elads, I use Virtual Audio Cable to route the audio channels to Reaper. The sonys are connected via physical cables to USB audio devices.

Oh well we can solve that. Let's see: Let's use the GPIO pins out on a raspberry pi and mount an LED on top of each speaker, just to make sure we know which channel is transmitting! When can even put an LED display on top of each speaker that displays the operating frequency!

 
It could get crazy, but what fun!

Reminds me of the "cocktail-party effect" papers from the 1970s, where a binaural phasing network was used to spread out the received audio frequencies from left to right, so your brain could concentrate on a signal coming from a particular "direction".

Not sure you can do anything to filter out the policemen shouting "SPLEEEEEET!" "UP UP UP", "WRONG VFO EEEDIOTTT" though!

Re: FDM-SW2 questions

Neil,

Those were great instructions, and I experimented with success. Awesome capabilities. But, answers lead to more questions!

You know the part where you encouraged putting RX1, RX2 and RX3 in different ear configurations?

Immediately I thought: What if I hooked up 4 speakers for spatial separation?!

Wow that would be really nifty. How to do that?

One way I can think of would be to take my Alesis USB/Firewire Audio mixer and connect it to the same PC. Then I could assign each of the RX channels to my software (maybe mixpad). Then I would push out each channel to a different mixer aux-out port and line level wire that to a small powered speaker. Important to use the line level as that's not amplified as is the XLR/Mic.

What do you think? Awesome if it will work. That way your brain can really fire on all cylinders - you could keep things sort of consistent with the colors Red far left, yellow next, etc.... In this way your operator skills would be very quick instead of trying to figure things out there is 3D context on everything.

This is exciting stuff. Innovation.

Thanks Neil, and thanks Mike for confirming I am not the only one having issues.

 

Neil: Thanks for your comments. I will try all that later today.

 

Mike:

 

Just as far as getting TX to happen on RX2 frequency, once you command RX2 so that the slice appears on the pan display, you then have to click ta the bottom of the slice display and click on the RX that shows under the display, and click it to TX.

 

Then the RX2 frequency becomes RX and TX, with TX on that frequency.

 

YA HOO! I’ve mastered that much….:=))

Re: FDM-SW2 questions

Neil Smith G4DBN
 

Working split: (I hope the images come out OK....)

1) Click RX1 red button (unless already selected - you should see the red underline beneath the button to say RX1 is the tuning context.)

2) Set to the required receive frequency and mode, ie where the DX is transmitting, say 14240kHz USB

3) Click the RX2 yellow button, it should go solid yellow and underlined. Set the required transmit frequency and mode, say 10 up, 14250kHz USB

4) Click the yellow TX above the waterfall to set yellow channel as transmit.  DUO should now have SP on the display

5) Ensure that the speaker icon for the RX1 channel (to the left of the volume slider) is enabled

That's it.

Leave the yellow channel in the selected tuning context so you can move RX frequency, or click the red RX1 to put that into tuning context if the DX moves frequency. 

When you transmit, the frequency and mode will be those set for the yellow RX2 channel.  Receive will be the frequency and mode of the red RX1 channel.  Make sure both L and R are selected on RX1.  Vital setting: In Setup->Audio, make sure you uncheck the "Mute the VRX not selected" button.

Now if you want to have different channels in each ear, unmute the speaker for RX2, unselect the R channel for RX1 and select only the R channel for RX2.  That puts the red RX1 in your left ear and the yellow RX2 in your right ear.

If you want to get really fancy, select the RX3 channel and point that at another part of the pileup and select the right channel for RX3, and you will have the DX on RX1 in your left ear and the RX2 and RX3 in your right ear.  For total madness, do the same for RX4.


And that is all there is to it.  Ignore the Vol2 setting in my screen, that is for my AUX output for digimodes, spectral analysis and so on.

Actually, I was unable to enable split in sw2 at all such that when I transmitted, the RX frequency would change to the TX frequency.

Hi Neil and all.

Well, in deference to my /O problem I mentioned earlier (Idiot/Operator), I did find the VAC webpage.

Yes, I now have an intuitive understanding of what "Virtual Audio" means in this case.

And Neil, your elaboration was excellent. I can intimate what is meant when one "ports" an audio channel to an application. I think I got that.

So somewhere there must be a control panel, or control application that! allows specification of what is to be ported where.

I see in your explanation that you port things to WSJT. Got it.

In my case, I set the playback and recording sound sources for Windows 7 to the FDM audio drivers. Then I set the sound input and output sources of WSJT, HRD, N1MM, DX4WIN, etc. to follow the FDM-DUO drivers.

It all works wonderfully.

But now, how on earth does one get to operate split?

All I want to do is start FDM-DUO SW2, display the band, tune a DX station on VRX1 and listen to the DX station in my left ear. Then, when I see the pile-up responding to the DX station's call, activate VRX2, make it the transmit frequency, and listen to the pile-up in my right ear.

My logging program will do what it has to do, and I can "tune" by watching the pile-up display.

Then I want to activate VRX2, make it the TX slice, and listen to the pile-up using VRX2.

I tried to understand how VAC operates by r! eading their webpage. VERY comprehensive. Now, if I wanted a PhD in VAC, I'd spend a lot of time there.

I downloaded VAC 4.0.9 and at first Windows 7 balked at installing it. Now it is installed and I am extremely pleased to see the very nice control panel it gives.

But how the heck does one marry VAC to FDM-DUO SW2 in order to achieve a split function?

BTW, to all who may be wondering why these stupid questions.

I asked ELAD about the possibility of an explanation about these set-up procedures.

 Franco sent me a separate email saying a new SW2 users manual is due out, and will go into detail on the audio channel setups.

FANTASTIC!

I need some help for the NB problem in the FDM-DUO when used stand-alone.

I checked with various signals, both AM and SSB, but I am unable to detect any
distortion, as reported, on the audio. A couple or better three audio files that
show the problem could be of help.

And also a confirmation that the distortion is perceivable when the DUO is used
stand alone, as opposed to when it is used with SW2.

Thanks.

Thanks Neil, Dave, and Pat.

 

Well, the VAC website is certainly instructive. And I fully understand the concept of Virtual Audio Cable. I simply did not know there was a software product called Virtual Audio Cable (VAC), and that I needed it!

 

I am now curious about the actual set-up steps. I’ve had many pleasures working with Windows sound card applications and set-up, other applications that must play with Windows, etc.

 

None were pleasant experiences!!.

 

And the VAC user’s manual is extensive and detailed, but not I/O proof. For example, the startup instructions state one should make sure the control panel has 1 – 3 cables indicated

 

I see the control panel, rather intimidating! Then I see in upper left hand corner an icon for cable, and a numeral 1, and a corresponding intimidating line of digital gobbledygook in the lower display that corresponds to the cable 1.

 

Boy, that is really clear………….. DUH!

 

How does one marry all that good stuff to the FDM-DUO SW2 application, and other applications like the logging program?

 

I am looking forward to learning that.

Hi Dave,
it seems that the serial is already kebt busy by the system
could you please verify the part "raspi config" to see if the serial is not already involved in "login shell" ?
Regards

Giovanni HB9EIK

p.s.: "login shell" is usually enabled to let you command the raspberry PI from a serial terminal connecteed to the serial. This, of course, locks the serial, and, when you use Cotecom you obtain error 11.

what is the max. bandwidth the rca cambio can use with the elad software? As a conclusion to my test with the Trekstor surftab I found this one not suitable. So I desire to get a cambio. The Trekstor could only run recordings with 153,6 kHz, the test comes here fyi: Listening, recording and playback with the Trekstor Surftab Wintron 7.0 (II) - Reflections about a remote shortwave listeners station

Re: FDM-SW2 questions

I'll answer the best I can. A VAC is a 'cable in software' rather than a piece of wire to connect the (sound) output of one program to the input of another . There are a couple of different VAC's available - I use Muzychenko.

The routing is done under settings - Audio tab. In the Output Device drop down you should see your VACs listed. Select one, and the mode you wish to use (usually audio, or MUX for RDS).

Then ensure that the input of the downstream device is set to the same VAC.

I'll leave your 3rd Q to someone else

Fine tuning ... off ...

Richards <jrichards@...>
 

My ELAD FDM-S2 tunes 1500 kHz off the correct frequency.

Is there a way to fine-tune the rig or the software so it plays on the correct frequency? Mine plays 200 kHz off. Example - All my radios sound right when tuning upper sideband 14.225.00 MHz - but MY ELAD FDM-S2 tunes it as 14.225.150 MHz. Is there a way to fix this? I use both the ELAD SW2 software application, and SDR Console. Any traction?

Thanks.
