I know exactlybwhat the "very fine manual" says..
BUT the question I ask is "What is the behaviour of the ATU when the target is set to 0" ?

Elad CPU Usage

George Stein - NJ3H
 

Greetings,

I am using an Elad S2 on a Win 8.1 quad core 16 GB computer.

I am using the native Elad software and also SDR Console (SDRC)  (not at the same time, of course). Also I am using the 3.072 MHz bandwidth.

What I am finding is that CPU usage under SDRC is now running 35% CPU usage.  With the Elad native software, the CPU usage is about 11%.

I also tried with my Perseus.  Native Perseus software is 12% and with SDRC is 12% as well.

Up to a few weeks ago, The Elad with SDRC would start out at about 30% and then perhaps a half hour later, would be at 15%. But this no longer happens.  In fact it is running much higher than the 30 %.

Has anyone experienced such a high CPU usage with the Elad and SDRC combination?

Any suggestions to lower the CPU usage using the Elad would be greatly appreciated.

Regards,
George, NJ3H

Hi Dave,

Cannot say what happen when set to 0, but it is not logical value. But you could1.5 try and tell us what happened ;-)

But when set to 1.5 it tunes until 1.5 or better is accomplished, or when i.e. 1.8 is best result, it stops, and when best tuning is higher than allowed, error message will pop up "too high VSWR"...

Good luck
Espen

Sorry to hear your problem, I would check the following:

The ART must have the tuner installed, of course, and set enabled via the front buttons on the ART.

Next It is really written in the manual long press on P3 for tuning, but on my Duo/-art I use long press on F4. (MODE button)

Suggest to check status of firmware and software to be updated.

Do not be afraid of raising a support ticket on this page: http://support.eladit.com/open.php , they are happy to fix your problem, even remotely when your ART is connected to internet...


Unable to Tune theART-60 from the FDM-DUO

David KK7SS
 

I've followed the instructions in the FDM-DUO and ART-60 user manuals to the letter.
But a long press on F3 on the FDM-DUO does NOT initiate a TUNE on my ART-60.
I can initiate a tune from the ART-60.
Any suggestions welcomed

Re: FDM-DUO broken by power interruption to DUO-ART

Perhaps there's a capacitor inside keeping the voltage up on some processor, just sufficient to maintain memory contents in very-low-power mode and it needs [several hours] to leak away.

Pure speculation

Well… after leaving the thing for a day unpowered, I now find it’s working again! It’s a bit of a mystery because, as I described before, I’d stripped the FDM-DUO down to complete, unconnected, stand-alone mode on a separate PSU, power-cycled many times, and the problem persisted. I’m bemused as to what can be “fixed” just by leaving it unpowered for a longer period of time…

 

I, too, had tried changing bandwidth when the problem presented – but in my case it didn’t fix it. The displayed noise floor changed slightly as the bandwidth changed, as one would expect… but never less than about 9+20dB on the S-meter. I wonder what fault condition, or strange state of the radio, could cause these symptoms?

 

The intended final use for this FDM-DUO is at a remote location, so I’m a bit concerned as to how to safely and reliably power it up and down…

Hello Mark,

My DUO behaves like yours sometimes when the PC is booted (I always power-up the DUO first before the PC). It has done so for about a month. The S meter is at S9+40 all the time until either SW2 is started and the spectrum starts running, or when I use the E2 knob to change filter bandwidth. I haven't reinstalled any firmware yet but should maybe do so. I asked the group for advice but no reply so I guess we should raise a support ticket.

Re: FDM-DUO broken by power interruption to DUO-ART

Mine does the same when running from an external 10MHz reference and this is momentarily interrupted.  It doesn't recover and goes to full-scale noise even if 10MHz input is restored.   I just reset by switching power off and back on.   That's in standalone mode - don't know about SW2, I rarely use my FDM-Duo in other than in standalone.

Will have to experiment using filter bandwidth setting instead of power cycling to reset from that situation.   Occasionally the 10MHz is glitched when I switch on a piece of test equipment in the same rack that also takes in the reference.

FDM-DUO broken by power interruption to DUO-ART

Mark EI3KD
 

I just wonder if anyone has seen this failure before, and anything I can try to fix it, before I send my FDM-DUO back to Elad:

My FDM-DUO was connected to, and powered by, my DUO-ART 60, when the mains power to the DUO-ART failed - a simple disconnect, no mains voltage spike or anything, and the FDM-DUO was in RX. When the mains power was reinstated the FDM-DUO RX had "failed" - indicating a constant S9+20dB noise floor. TX, as far as I've tested it, seems ok.

I've tried resetting the FDM-DUO settings to factory default with no change, and also tried it completely disconnected from the DUO-ART on a separate PSU - again no difference. I've also tried exercising every relay I can think of in the FDM-DUO, with no success.

Both the FDM-DUO and the DUO-ART are using current firmware.

I'm extremely disappointed this can happen, because the scenario of mains failure seems a reasonable possibility - It seems likely that the DUO-ART 12V output (or something on EXT-IO?) has "spiked" and killed the DUO :(

Others might like to beware of this possibility!

Regards, Mark


Re: Tx adv features on sw2 and ptt

Neil Smith G4DBN
 

If you break out the mic socket PTT on the back of the DUO and use that for a footswitch or external mic switch, doesn't it transmit OK using the advanced TX? 

Easy to test by setting Menu 32 to USB then using the hand mic as PTT only, and using a signal source from something in the PC, perhaps via a virtual audio cable.  OK, the PTT light on the advance panel doesn't light up, but the rest of SW2 is aware it is on TX.

I usea breakout box to connect my Heil headset and a footswitch, you could plug the Shure PTT into an adaptor via the RJ45 easily enough, I should think.

yes i can wire shure mic into audio in on pc to allow the tx adv features to work ( compression etc.)

i do not and will not use mouse ( etc.) to enable ptt..or use vox..i hate vox!  ( my house is far to noisey for vox and having a mic in one hand and mouse in the other just to tx is just stupid!)

FDM-S3

The S3 will arrive to a dealer near you....can any one at Elad tell me what the options are,
and does the price  ( Elad website )  include theses options .?

I will be selling one of my FDM-DUO ( red ) plus Hardrock 50 PA to assist in the puchase of the
S3 ...and  ATV-Sat tuner ...Watch this space if your interested..Roll on July 30th.

Re: FDM-S3 availbility

Hi, thanks for the answer ! That has been my trouble too when using FDM-S2 with SDR Console and Server version 3. That's why I was asking about version 2 of SDR Console + Server, which gives a smooth remote connection with FDM-S2. Simon has stopped updating version 2, but can this be on the things-to-do-list for Elad ? In such a case I would purchase an FDM-S3, as it seems to a real treat for a DXer.
