Are u using the original, ELAD DUO supplied DC power cable and connector?

I’ve tried two different power supplies, checked the supply voltage which is fine.

Re: SW2 software shuts down after random amoutn of time

I’ve seen the waterfall on SW2 freeze, turning into a smear and audio stops. That seems to be the most common crash I’ve seen over 5+ years of using SW2. But for the GUI to close completely I can’t say that has happened to me very often if ever and not on a recurring basis.

 

I assume you have turned off any screen savers and maybe set the Windows Power settings to “High Performance”. All just guesses.

Experimenting with what causes it. If I minimze the window (tuned to a station) it seems stable so far for over 30 min..

Re: FDM-S3 restart after PC restart/power outage - question for support and other S3 users

Guido Schotmans
 

Hello Bjarne,

 

I’m using a SonOff in the power lead of my remote NUC. Dirt cheap and I didn’t notice RFI yet, but I’m not in an environment comparable to Norhtern Norway. Worth to give it a try.

 

73,

 

Guido.

Winston: Yes, in fact I have one. The problem is these devices emit lots of RFI, so I'm afraid it's not an option.
Richard: I was looking at devices like that, and I even found one with dual-voltage, EU-plug. The cost was rather prohibitive though, close to USD 300. There is a GSM device that was used a lot in Norway before rural broadband, I might check that one out.

Re: FM filter on FDM-S3

Larry Dodd
 

Srinivas,
You need an antenna. If you have FM stations close to you try a single meter long piece of wire connected only to the center antenna connection. See if you hear anything.  You need proper antennas for the bands your interested in.

Thanks for your responses.
I tested 1) turn off Lenovo, 2) turn off S3, 3) turn on Lenovo, 4) turn on S3. This worked.
So, in order to get the S3 up and running again, I need to be able to switch the S3 off and on via the internet.
Any suggestions how to go forward?

You can use a smart plug connected to the internet and use the plug app to control the power.

Re: FDM-S3 restart after PC restart/power outage - question for support and other S3 users

Willi Westrupp
 

Bjarne tnx for the problem. Same here. You need (1) a Script that restarts the NUC and Console e.g. and a time switch for activating S3 after restart. Or (2) if you are with the S3 close and start Console and switch on S3 after this done.

In a 12 V environment live mine the whole System works perfect when the S3 is powered all the time. I restart the NUC with WOSB software. Its always connecting this way.

Hello Bjarne,
 
I experience the same issue sometimes with my laptop (Lenovo Thinkpad P50). I need to shut down the laptop and switch off the S3 to save battery when I listen at my off-grid cottage. It seems that perhaps half of the time I need to reconnect the USB cable after booting up the laptop.
 
A remote controllable USB switch should do the trick to overcome this issue if there is no software fix.

Betreff: [EladSDR] FDM-S3 restart after PC restart/power outage - question for support and other S3 users
I have been testing the S3 today, including taking it through some of the situations which happen on a remote, sometimes unaccessible place.
If I do a restart of the PC, or if I simulate a power outage, the FDM-S3 cannot be reached again. I need to unplug and replub the USB cable for it to be visible. I suspect this is due to the Cypress USB bootloader. I experienced identical symptoms when I tested the RX888 last year. It too had a Cypress USB bootloader.

Now, this is a showstopper. However, one should never rule out operator error or other local problems. So if anyone have observed the same, I would like to know. And if Elad is aware of this, I would be very interested in finding a solution, so that the SDR can be connected to after a PC restart or a power outage. This is a number one priority for me if I am to keep the S3.

How about a four pole relay that disconnects the USB and reconnects as needed.   Use a small one (two relays probably to get 4 contacts) and keep wires as short as possible and you shouldn't upset USB operation
 Or opto-coupled AC FET solid state relays

Re: FDM Duo CW

GLENN NUTSEY <glennnutsey@...>
 

Good morning Klaus,

Thank you for taking the time in giving a full explanation. 

It’s cleared up the gaps in my knowledge nicely. 

I’ve been practicing morse on and off for two years and I get great satisfaction in using it. 

I have had many many radios along with linear amplifiers, but the satisfaction for me is making contact on low power  

The Elad is a superb radio, especially when using it as a communications receiver with short wave listening being my main interest  

I now have the best of both worlds.  If I wish to 
comment on a fellow OM on the bands I can do, or if I want to dig out those weak signals that’s possible too with this fine radio.

Regards

Glenn

 


Re: FDM Duo CW

Klaus Brosche, DK3QN
 

Hi Glenn,

16 wpm is not too bad for a CW newcomer ;-)
Congrats!

I'm always feeling sort of "happy" if newcomers take their efforts (and time) to get involved in
CW operation on the ham bands!

Re. "CW", "CW+", "CW-" etc.:

In the "old days", Transceivers/Receivers had just *one* CW mode setting, which was "CW".

As I do not have my "oldtimers" in front of me just now, I can't say which side of the carrier
the RX frequency was shifted to, typically. I'd guess "up".

Then there were (and still are) radios which offer "CW" and "CW-R" (CW reverse sideband),
which basically is the same as "CW+" and "CW-".

In any case, there is a need for shifting the RX frequency up or down a couple of 100 Hertz
in order to make that CW signal audible.

If you'd tune to the TX carrier frequency itself, you'd tune to "zero beat" and won't hear
any readable CW code signal at all. Quite likely only some key clicks of that CW signal.

More recent radios have the user selected CW sidetone frequency (say 650 Hz) synchronised
with the RX offset frequency.
So if you tune the partner station to exactly that 650 Hz beat tone (your sidetone frequ.),
you'll be transmitting (TX-wise) on exactly the same frequency (zero beat) as your QSO fellow.

More recent radios support this kind of frequ. synchronsation by means of a front panel button
labelled "zero in" or similar and the synch process is done via the radios "brains" (processor).

The benefit of having both "CW+" and "CW-" (or "CW" and CW-R") settings available on a radio
is such, that under severe QRM related band conditions (e.g. during CW contests) you are able
to choose on which side of your CW filter (discrete crystal filter or DSP filter) you'd want to
copy your fellow hams' CW signal. By just changing that "CW sideband", you can move your receive
channel much further away from that QRM signal and may make his signal a Q5 copy then.

73, have fun on CW, and stay safe!

Klaus, DK3QN
