the way i send messages from the elad is by pressing the mic and my paddle
 at the same time. but if you go to  page 33 of the manual and look at command 62 and 63 that is where you get to select cw send message in the menu for wrong mod to come up your not in the right mode or you have split acitvate and your b vfo is still ssb

Hi All,


I understand from reading the manual that I can (once properly set up) long press the F4 button on the front of the Duo will send a canned cw message.


In the FDM-DUO Manager - CW Messages I put a message in the number 1 slot and saved it.


I then set memory 62 (F4) to CW MSG


Now a long press to F4 key yields - "Wrong Mod"


Would someone please tell me how to properly set this up.

Re: FDM-DUO Standalone strange behaviour

Jean-Michel Renoton
 

Hi,

No takers here...

Update : everything went for the worst. 

After sending this message I told myself that someone would hint at a firmware problem and that I should update everytning before asking any question. The FDM-DUO was bought in June 2015 and I had escaped nearly every problem since that. FDM-SW2 was 1.96 and RX/TX/USB/UI were whatever they were (I didn't write them down) before  I upadted all the firmwares. Now I have UI 4.48, USB 4.09 RX 01.24 TX 01.25 and FPGA 02.00

And now the FDM-DUO doesn't work in standalone  with Ham Radio Deluxe, neither on the desktop nor with the netbook. Each time I try to transmit, I get SWR ------ and a 8 to 10 dBm output power. Maybe there's a setting that I should have altered and I don't remerber whch one. I'm using the TS480 preset with 38400, CTS and RTS checked, DTR unchecked. BTW Fldigi with TS480 Hamlib doesn't work either.

Any help would be appreciated.

Hi,

I've got a question that bugs me. I'm using my FDM-DUO on 2 different computers. The first one is a desktop DELL with a Core 2 Duo (E6550@2.33GHz), 4 Gb RAM, and Windows 10 64 bits. The second one is an HP Netbook DM1-4430sf, with an AMD E2-1800 APU with Radeon HD Graphics 1.70 GHz, with Windows 10/64 also.

I'm a digimodes man and love my free HRD (V. 5.0 b 2893) a lot. At max power, I get 40 dBm with the netbook, and only 33 dBm with the desktop. As far as I know, all the settings about audio are the same, I use FDM-DUO Audio Device on input and output, and set up playback at 100%.

Where should I look to find an explanation? And a cure of course.

CODAR "filtering" ........

Mark Pettifor
 

Greetings,

This is a question for the more technical out there...

Radios have always had a noise filter / noise blanker that works on certain types of noise - noise with fast transients like the turning on and off of a light switch, or the pulses of an electric fence, or even static from thunderstorms.

As far as I'm concerned, CODAR is a "noise" that I'd like to have a way of filtering out, especially on the lower half of the 60m international shortwave band.

For you who understand this stuff way better than I, do you think that, theoretically, an RF source generating a signal like that of CODAR, can be somehow filtered out, leaving any other signals underneath in place? CODAR is a sweeping signal, and the shortwave stations underneath are not, so maybe that characteristic can be used to create some kind of filter?

Since CODAR doesn't appear to be going away any time soon, maybe the radio listening community can come up with a way to filter it out. Maybe some day, the "CODAR Filter" ("CF"?) button will be as common to see as NB or NR?

I can only dream, eh?

Best regards,

Mark

Re: Virtual Radio Scale: ILG with 31.000+ entries

Hi, I agree with Nils that ILG database is really comprehensive. I'm using S2 locally with SW2 (ILG csv-file) and remotely with SDR-Console (ILG dbf-file and Ergo4). The database is updated regularly. I too have no commercial relation with ILG, I have paid for the files. But rather moderately.

Dear Alberto I2PHD,
Thank you for looking into the auto notch problem. I often have the same problem in this video. My experience is that monitoring a very strong station, say 30dB over s9, will create this bug. I often switch between AM broadcast stations and the ham bands. After listening on the AM band if I want to use the auto notch on the ham bands I have to cycle power to reset the radio before the auto notch will function correctly. It sometimes occurs when listening to ham roundtables where there is a very strong station and many weaker stations. The bug also affects the audio gain structure. The audio will become extremely loud then fade back down. I hope these clues help you troubleshoot the software.

Re: OT: Computer case with good EMI/RFI protection

lasse moell
 

Having far too many computers in my house... It's my gut feeling most EMI originates from switched power supplies!
Now using ferrite (grade -31) and having good coaxal cables to radio seems to tame most of it. Now the closer the antenna is to the EMI source the harder it will be to elliminate. But if the antenna is 10 meters from the EMI source it should be useful, I have my active loop 5 meters away from the house and it is OK (not stellar) but totally useless if I have it indoors. TTBOMK the noise I hear now, is not coming from sources controlled by me!

Have a look at SM5BSZ videos on Youtube regarding EMI... very very informative.

It just strike me.

I would have been really interesting to see some measurements of emitted and conducted interference from a stock PC box with with just power hooked up to it. Then systematically measure again as all accessories is hooked up. And finally measure what difference some normal anti noise measures have.

I've seen measurements on PC based navsystems for ships, but then the whole the system is designed with EMI/EMC in mind. But when you look closer it's not that much different from a stock PC.

Re: OT: Computer case with good EMI/RFI protection

Hi

You can make a Faraday Cage external thick metal mesh.
You must
keep in mind that the connections that enter and leave the PC also radiate.
You must
put ferrites in all of them.
Also
you must check the effectiveness of the filter input power source to the PC. This is the main cause interference.

It has been very interesting to read all info on this topic, both in the list and directly to my email. Thanks!

I know by experience how important the case is for low airborn emission. The components in the case are equally important and definately also the cables (there are a lot of junk cables around). Not to forget to PCB layout and the connectors. It all ends up in a complete electric system that emits EMI either airborn or via the cables. In my research for a good computer case I haven't found one that seem to fulfill my requirements. They are all looking very nice but they are not designed with EMI in mind. I have slowly shifted towards buying an assembled computer from HP, DELL or similar. Since the assembled computers have to comply with FCC, or in my case, CE rules, the chanse for having EMI trouble should be much less. I run a CLEVO laptop today without any problems at all but it is approaching its end-of-life.

Has anyone run into this with their DUO?

J.R. Jesson, N7JRJ
 

Today I was running my Duo on battery to sniff for noise at my QTH.  While doing this I ran out of battery, and the rig started to fade, so I cut power, and connected to my DC power supply.  When I reapplied power and attempted to reconnect the Duo to the SW2 software, it appears that my serial number is now garbage, and the SW2 faults when I try to connect the rig.  

The interesting thing is, everything else appears to work, although I haven’t attempted to transmit.  I’ve reset the rig a few times (menu item 81), I can see my serial number in the UI (menu item 83) and have checked the issue with a second PC and different USB cables, all with the same result.  I’ve attached screen shots.  I’m current on firmware. 

I’ve logged a ticket with the Elad team, but am curious if anyone else has run into this?

Hi - a sneak preview of Simon Brown's SDR software "SDR Console"
presented me with 24 virtual radio channel with the bandwidth of an SDR
(i.e. 5 MHz with an FDM-S2).
Each channel may be individually tuned with e.g. frequency, mode,
bandwidth, AGC etc.

Please find a first example here:

This example shows how to monitor 24 broadcasting channels in parallel
(with different bandwidth and modes, e.g. ECSS-U/L or plain AM), to
record all these 24 channels in parallel and to play their content.
I tried out also three FDM-S2 with one PC, resulting in a bandwidth of
15 MHz and 72 channels. More to come.

Cool. I should perhaps try this with my two S2s. However, management of all these separate channels and required multi-track recording may turn out to be rather challenging…
