Nice to see you solved it Keith, but that is definitely not the reason why
this is happening here. I have to search further. Anyway, thanks for
telling.

FDM SW-2 SOLVED for now

I was copying some info from a CD to a USB thumb drive while
the jumping was happening. Basically stopped after I
finished copying. Tried it again and the jumping started.
Switched out CD's and thumb drives and no jumping. Put the
original Thumb drive back in with different CD's and spectrum
started jumping again. Looks like a bad thumb drive???

Hello,

Since some time I have a strange issue with my ELAD FDM
S2. Now and
then the spectrum starts to jump up and down for a some
minutes but
recently it is happening much more often and for a longer
time. It
is only happening in the regular broadcast FM band. Not
in the OIRT
band. After some time it goes away automatically. I
don't see the
jumps in SDR-radio V3 in combination with the Elad but I
think that software is just smoothing the jumps away.

You can see in in this short video:

https://youtu.be/zRvXUA1p6Vw

Note that the amplitudes and noise floor are both jumping.

Here two pictures from the beginning and the end of the band.

and
https://app.box.com/s/m7sr87rqc9okzygf4jg2v0usbf1koazc

So you'll see that the dancing noise floor is not
occurring further
away from the FM broadcast band.

I am wondering what can be the cause of this. I have checked the
connections and they seem to be OK. As said it only
happens in the
FM-band. Can this be caused by some kind of external
interference or
is the chance that it has to do with a hardware failure
more likely ?

I hope somebody can help me.

Guido.

Lock To CF

How do I unlock / release the white tab button: Lock To CF under RX1?

It is sticking and will not un-release by mouse clicking on the tab button.


Comments welcome.

Dxcluster does not work

Frans Gosen
 

When I try to connect a dxcluster I get connected to "login"
When I sent my callsign I get as answer "PA3CDN is not a valid callsing"
(On different Dxclusters I get the same message)
It worked before fine but after a Windows10 update it failed.
Also the comport 5 has been changed in comport 4 after the Windows10 update.
The Elad FDM Duo works normal so far I can see.
Any suggestion ?

Re: FDM DUO vs Flex-Radio 6400

charlesristorcelli@...
 

It means that the PA will be the portal to connect your FDM-DUO from anywhere in which you can get on the internet.

TRhis is more commonly called "remote control".

It is what the world of K3, FLEX, and ICOYAWOOD is doing.

At that time, with the FDM-DUO docked with the PA, you too will have the a rig that many consider suprerior to FLEX.

FDM-SW2 setup with Fldigi

greggilbert195@...
 

Hi Group,


Would like to see if one can setup the FDM-SW2 to control the Fldigi software. And also have the Fldigi control the SW2. 

FDM-SW2 setup: Remote Ctrl:

1) What CAT Mode to use?

    a. Standard

    b. Slave

    c. VRX

2) Use Omnirig? What settings?

    a. Rig 1

    b. Rig type FT-897? // or a TS-(xxx) setting?

    c. And other tabs....Data bits, Stop bits, etc.

3) Fldigi Configure: Rig control:

    a) Use Hamlib...?

    b) Rig Yaesu FT-897 (Beta)? 

    c) And other tabs....Data bits, Stop bits, etc.

Thanks for any ideas.

"1. Sherwood Engineering has not done the performance analysis they carry out ofr all ham radio transceivers and publish them. Again, IMHO when they do, DUO will equal or outperform them."

Will be interesting to see. Sherwood's post on the ic7300 puts it 1 db below the yaesu ftdx3000. This is with the IP+ attenuation off, which is sherwoods recommended operating position. If you turn IP+ on, it improves the imd but trashes the noise floor.
Not to say that the ic7300 is anything less than an outstanding new product, but sherwood did not put it at the top of the list. In fact, a more objective analysis would move it below the ftdx3000.
The upcomming ic7610 will likely not fall much higher on the list.
However, i applaud icom in there efforts to introduce new technologies.
I am anxiously waiting for the successor to the duo.
Elad has produced quite impressive technology.

Re: FDM DUO vs Flex-Radio 6400

charlesristorcelli@...
 

Very interesting comment, and as a FLEX owner, 100% agree.

Nothing wrong with FLEX, don't get me wrong. It is a very good radio.

But in user interface simplicity, intuitive layou of the desktop interface to the radio's software, and performance, DUO BEATS FLEX HANDS DOWN!

That was even confirmed by one of the FLEX design folks who told me at dayton that they wish FLEX had the user interface developed for DUO.

A couple of other things to consider.

The cost! FDM-DUO costs less than 1/2 the price of FLEX 6300, and a heck of a lot less than that compared to the 6400.

FLEX does not have a stand alone mode, unless you then buy the MAESTRO, or the supposedly new MAESTRO built for the 6400. And either of those will add about another $1,000.00 to the total cost.

DUO gives you 4 slice receivers against only two for the FLEX 6300, and DUO lets you listen and operate on 8 slice receiver, 4 on each of two bands. That finally gets the 6400 at par with the DUO.

The only two shortfalls for DUO against FLEX, IMHO are:

1. Sherwood Engineering has not done the performance analysis they carry out ofr all ham radio transceivers and publish them. Again, IMHO when they do, DUO will equal or outperform them.

2. DUO only gives you 5+ watts output against the FLEX line. That is definitely a DUO shortfall, potentially resolvable with the the announced ELAD Linear amplifier, that WILL ALSO GIVE FULL INTERNET IP ACCESS TO THE DUO.

DUO is unquestionably an equal or better radio than FLEX.

Hi Guido.

It shure looks as strong broadband signals is interfering with the signals of your interest, and not an anomaly of your receiver setup. The reason it does not show up in SDR console is probably due to different averaging. It may be changed in SW2 in the setup under "Graphics" -> "Plot Averaging".

The simplest way to check this is to remove the antenna cable to the sampler when it happens. If the waterfall (ie. noise) is steady, it must be due to external factors. If it still jumps it must be internal.
