Re: Set Up to use JS8Call with Elad Fdm Duo

Neil Smith G4DBN
 

Let's see if we can fix this one bit at a time.

First step, let's find out if CAT is working at all.

Using the same COM port that works as a TS-480 in HRD, and with no other programs running that might be locking the COM port, confirm that the WSJT-X or JS8Call settings are the same as worked in HRD. Should be 38400, 8 N 1 as usual.

Now I'm going to assume that you are using the latest JS8Call or the latest WSJT-X (so you have the current Hamlib setup, which is built-in to those).

Check that you have the radio type set in the program settings to Elad FDM-DUO in the drop-down box (don't use TS480, the Hamlibn for that is buggy, the DUO library functions are new and work perfectly)

Check that you are set to PTT using RTS on the same COM port which worked OK with HRD for CAT. The rest of the settings shouldn't matter at this point, but set them anyway to Fake It split and USB mode so you don't have to go back and fiddle with the settings later.

Assuming that is OK, and the settings are all correct, click the "Test CAT" button.

If that doesn't go green within a second or so, we need to dig further into whether something is stopping the COM port from working, so stop at this point and report your findings.

If it does go green, then click the Test PTT and see if the rig goes to TX.  If it doesn't, then check the DUO menu 54 and the PTT is set to IN+RTS, then retry.

If that still doesn't work, you have a different issue around the RTS line, so change the PTT setting to CAT and try again.

So, now you either have CAT and PTT working, or just CAT or neither.

Can you test and report on whether those settings work in JS8Call and/or WSJT-X?

Next step is to get receive and transmit audio working, but let's go one step at once.

Good advice from Charlie. Get FT8 working with WSJT-X first as there are more users out there to ask for help.

I had never tried JS8Call, so I checked my setup with WSJT-X first, then downloaded and installed JS8Call with all defaults.

Set up looks like this:




I have TXIN on the DUO menus set to AUTO and PTT set to IN+RTS.

When I hit Test CAT, it worked and went green (my default COM port is COM3, discovered the way Charlie suggested). Then I hit Test PTT, the rig went on to transmit and the button went red.

For the audio streams, I normally use Virtual Audio Cable wiht SW2 on receive, but for this test, I picked the FDM-DUO audio device on TX and on RX

I set the DUO menus for AGC OFF, AGC GAIN 1 and AUX VOL about 6 to get the level in JS8Call somewhere in the 30-40dB region on band noise. I also messed with the gain on the Windows audio device for the DUO to drop the gain a bit

Seems to work fine.

Much simpler for me to use SW2 and Virtual Audio cable as I have multiple receive programs listening at the same time to the virtual device and don't want to playh with JS8Call, but it looks like it is just the same to configure with the DUO as WSJT-X

You did not specify your operating system, but I will assume it is Windows.

Make sure your DUO is powered off, and get the System display under Control Panel opened.

Take careful note of the USB ports listed.

Now power on the DUO and you should hear three audio "pings" as the DUO drivers get loaded. You will see ELAD samplers, the ELAD audio card, and a com port appear with each ping.

Note that comport number.

That is the com port to your DUO.

Hello again Raimund,

I fully agree with your comment. Just as a curiosity, there is a third "flavor" of PC:s that might be inherently silent. Field laptops certified against MIL-STD-461E. The older Panasonic Toughbook CF 31 MK IV was built like a tank and perhaps built to be used in a tank too. :-)

Re: Elad S3

Hi everyone,

Regarding ELAD specifications on top level, I believe that the dynamic range and receiver bandwidth is just fine already today. However, I miss a smooth and seamless VHF capability for aviation and marine monitoring. That would represent a significant value for me because it's far from trivial to achieve with readily available add-ons.

All the best

Re: Thinking of selling FDM-S2 and getting DUO-R

 

Anders H.,

i agree with you. Anyway i would like to point out that the noise can be reduced quite a lot.
I'm not using portable PC's, only BOX Pc assembled with a very low interference. A ready industrial product is never the same.

A portable PC might be useful but never like a real assembled BOX PC.

Re: Elad S3

For every opinion there's another, I'm not too fussed about increasing the A/D resolution to 24bit as 16 will be more than sufficient for my use but the 20MHz bandwidth is quite a game changer for broadcast FMDXing being able to monitor and record the entire band with one device.

Given it was first demonstrated in Feb 2017 I fear it could be heading down the vapourware path, whatever the latest story happens to be getting hard info is like extracting blood from a stone.

Re: Elad S3

James Buttons
 

As the (satisfied/happy) owner of an S2 (and the software) for the last 5 years or so, when I first saw the S3, its specifications and estimated selling price I was not impressed. I've stopped by their booth at Dayton for the past 2 years, no real new information.

US $1000 for yet another 16-bit A/D receiver in the market is a no-go for me. The increased B/W is not particularly important to me over what the S2 does.

I think their volume will be very low given the competion out there, if it ever sees the light of day. My guess is that they may be coming to the same conclusion?

Now, put in a 18-bit or 24-bit A/D and things improve and that may also help clipping problems that seem to be an issue for some S2 owners....

Secretly, I'm hoping that this is what's causing the delay and they're trying to figure out how to get a higher resolution A/D in it with minimal changes to the rest of the hardware. This is just my uninformed wish.

They may just be having supply chain issues with getting enough parts for production quantities. I know first hand, right now there are industry-wide shortages for certain types of components with lead times greater than 6 months that are affecting the release of many new products.

Time usually answers most questions.
