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

Otso Ylönen
 

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.
 
BR, Otso

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

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

Re: FS: ELAD FDM DUO, ART 120 and SP-1

Is the SP-1 the original SP-1 or the SP-1A?  I think that the actual model number is on the rear.   I take it that the remote feature is not yet working on the Duo Art?

Re: FDM Duo CW

Much depends on whether you prefer tuning up the band across a CW signal to cause the tone to rise or fall. No effect on TX frequency as Klaus has explained.

What would be wonderful is a simple way to make the transmit frequency rise by the chosen CW offset if you send CW while in USB mode. Transmitting zero beat to a weak SSB station is no use, so you have to mess about with offsets or split unless you have a magic controller box (evil laughter echoes around ‘DBN’s subterranean lair)

Re: FDM Duo CW

Klaus Brosche, DK3QN
 

CW mode is an intermittent carrier only mode.

In order to make that carrier audible, the RX (= listening) frequency needs to be shifted
either up or down from that carrier frequency.

Hence, CW- or CW+, up to your liking or up to QRM on "the other side" of the carrier frequ.

Re: Elad S3

Bill, because there are different ways to DX. I record continous IQ files with HDSDR along with "slow-scanned" FFT images so I can see the FM openings and play back interesting spots with Console.

Re: Elad S3

Andy G4JNT
 

What specifically would an EXTIO DLL do? 
The DUO specifies a clearly defined protocol for EXTIO input and output.  Is the S3 much different? 
Write your code for that protocol directly, instead of just hooking into some other package
Even a  mid-range PIC device can intercept the DUO's output

Or have I got the wrong end of the stick.

I know quite a few users who have bought the S3 specifically for broadcast FM DX so to hear the ExtIO probably won't be available until after the Sporadic E season is disappointing.

Hi,

an S3 specific ExtIO dll will probably be made but it is a development we will do no earlier than mid-2021.

Thanks to everyone for weighing in on the purchase of a used FDM-S2. Sounds like a solid investment.

Re: Guidelines on buying a used FDM-S2

Hello,
I have bought two Elad S2s used and another two new. The second hand ones have been as good as the brand new ones. Now, I have sold two of these (as I purchased a S3) and there have been no issues, as far as I know, with these units at their new homes.
 
S2 is a solid unit. The only wear issue that I have heard about is the "burning" of the power led, although I have not experienced it myself. And even that is just a visual thing.

No luck yet :-( 
In fact, it was a challenge to get native Windows to recognize the S3. I had to search for the suitable drivers by trial and error over the Internet.


Re: FDM-S3 "burn-in"

The attention to detail in the design is very evident. In photos, it's impossible to tell how much metal is in the unit and I can only imagine what the total weight will be with the downconverter and and filters installed. One thing I would improve is the tightness of the enclosure. There's a rattle when tapping on the top or bottom. And it's already mentioned that the power switch can be touchy.
