Check Menue 32 - Main Window - View on TX

You can set different Views for TX and RX

Thanks Uwe, seems the ASA-62 is not ideal for my use. Can it be switched manually on the front panel?

Re: Reminder - use the correct USB cable on the DUO's RX USB port

I don't have the original cable and software problems. Bought the ELAD second hand and it wasn't there.
Where can I buy a good USB cable?

tnx Boudewijn PD5BB

I mentioned this on another thread - but felt it deserved it's own - be sure to use the shielded cable (with the ferrite beads) provided by ELAD on the DUO's RX port. While I had done that, I ran it to a USB switch, and the switch connection did not have the protection to the PC. That caused my software to misbehave badly. Once I found a second suitable cable to connect the switch to the PC it completely fixed the problem.

Gosh, we really should do these things :)

Hi Simon,

I found this topic fortuitous in that I just solved an RFI problem this morning. In my case my HF transmissions would cause the software to shutdown on my PC. Not completely,. but would shutdown the audio in the RX. I remembered that the DUO needs a shielded USB cable, with ferrite beads connected to the "RX USB", and I did that, but then I remembered that I consolidated all my USB's into an external USB bus - which introduced a non-protected USB cable from the USB bus to the computer. So I simply put another well shielded and protected cable between the PC and the switch, and the problem disappeared.  So, be sure you're using the supplied shielded cable with the ferrite beads added. If you don't have it, do get one. You need in on the "RX" USB port on the DUO because that's how the radio communicates to the software.

Welcome to the ELAD family!

Re: ASA-62 Antenna Splitter - observation

Uwe S.
 

The remote control cable is not a standard USB cable, there is a small piece of electronics in the connector.
So far, you can only switch the ASA-62 with the original software.

I hope I could help,

Greetings Uwe


Re: ASA-62 Antenna Splitter - observation

Ron Liekens
 

Can anyone tell me if the coax shields of the connected antennas are isolated to each other and also to the output to the 2 radio connectors. In other words are all inputs and outputs completely isolated?

As I noted on the Elad website seem that the ASA-62 can be switched remotely. Seems this is a USB connection to a computer and will be switched by software. Is it possible to switch the box remotely via Ethernet? Most of my radio's are operated remotely via a SDRconsole v3.0.23 server.

Hi Antony,

I'd guess, some way or the other there is RF getting into your Mac machine.

Typicals 'suspects' for this to happen are any cables connected to the Mac.

I have one (of 2) radial of my 40 to 10m GP running down from the
elevated GP
feed point to about 2.5m above ground.
The radial end is about 4m lower and 3m away from the front of a room
at the 3rd floor (2nd Etage) of our house.
This room is currently 'populated' by our youngest son.
When I was testing my FL-2100Z a couple of months ago on the air,
his mouse driver stopped working/responding (USB connected mouse).
As this happened during one of his 'gaming sessions' :-)))
he was not amused ;-)
He had to reboot the PC and I stopped my Amp testing exercise.
Then there was peace again :-))

Hi Klaus

It is the track pad that stops working. On the MacBook it is double depth track pad for mouse clicks. As you press it you feel haptic feedback for first or harder second presses. This stops when I transmit and there is no clicks.

Must be an Apple bug I think. Have to use the ESC key to stop TX when tuning WSJT for example.

In any case: for SSB these features only work if the Mike is connected to the PC.
These do not work if the Mike is connected to the rear Mike connector of the DUO.
So all of this 'FDM-DUO Advanced TX panel' functionality is done within SW2 and
then sent down to the DUO via the TX USB cable connection.

Now to make a high pass filter from 1.6mhz for the rx only antenna ( lz1aq loop amp, homebrew,) as the adc clips with the loop switched towards the bbc transmitter on 909 khz.

If I start SW2 in Demo mode, subsequent attempts to open it on-line fail.
Same if I start it in in-Off-line Mode

Can't find anyway to get back on line,

In fact, from Demo mode, I had to uninstall, clear the registry entries and remove all files in Documents as well.

Anyone else get this.
Anyone find a solution?

Using S2 with Icom 7300 - Delay in return of full audio

Bill Alpert
 

I'm using a T/R switch and two antennas, a loop for receive only, and a vertical for transmit with my IC-7300. 
The S2 is receiving a signal from the PTRX-7300 device, installed in the Icom rig. I like to listen to the S2 as opposed to the 7300, as it seems to dig out signals I couldn't otherwise hear.

The S2 seems to know when I am transmitting, and a red flashes in the SW2 software accordingly. All well and good.

But, after my transmit cycle, it takes a moment to hear full audio from the Elad rig as audio seems to ramp up quickly, but still it takes a moment. I've fooled around with AGC off and gain settings, and that helps but doesn't cure the problem. In a fast paced CW contest, the ramp up can make it harder to hear the first characters of the DX station's response, if he is quick on the key.

Wondering: why the audio ramp up??
Also a point of curiousity: how does the S2 know I'm in a transmit mode, is it the strength of my local signal? Am I possibly overloading the front end?

Much appreciate any enlightenment on this topic.
