Re: FDM-S3 and CAT control

Conrad, PA5Y
 

Works fine with N1MM+, works fine with Omnirig.

 

I changed the port number to Port 6, still no joy with hamlib based applications. WSJT-X and JTDX tried to no avail. I can use Omnirig with WSJT-X but that will not work when I need more receivers.

 

Surely somebody MUST know what is wrong. I cannot believe that I am the only one having these problems.

This is driving me crazy! Please look at the screen grab and explain to me why this does not work! By the way, the Splitter in VPSE has the same baud rate before anyone mentions it.

Good morning Jim could you please share more details of your set up? Are you able to have multiple instances of CAT for each receiver? As far as I know SDRC can only support omnirig which means 2 instances not 3. You can of course create the receivers but not 3 CAT controls as far as I know.

 

I would really appreciate it if you could share your VPSE set up.

Yes, virtual ports needed. I use VSPE here.

Never used it with the Elad software, but have done with Console which emulates the Kenwood TS2000.

Hello all, my shiny new S3 arrived, and I have been using it on 6m.

 

I want to use RX1, RX2 and RX3 and CAT VRX with 3 instances of WSJT-X.  The problem is that there does not appear to be a com port for CAT control on the S3.

 

Do I need to create Virtual com ports, is that it? I have com0com or VPSE to do that. Any advice would be most welcome.

A fact to know is that for the choice of the S3 oscillator the important was to have in that order, a good accuracy, a good precision and then correct reception performances.

The internal 10MHz goes out of the S3 with a minimal conditioning circuit so its characteristics are not impacted. It is different regarding the receiver performance because there is an Si5338 which generates the internal needed clocks.

Headset VOX Through PC

Richard Meal
 

All,

 

Still getting to grips with the FDM-DUO and have to say that with each Op session I am more an more impressed.

 

Apologies for the potentially dumb question, is there a simple way to configure the SWB2 software to enable a VOX transmission via a headset connected to the PC?

 

Grateful for views.

ICOM IC-705 and ART 120

Hello, has anybody on the group succesfully interfaced the 705 to the ART 120 amplifier.

Needing to protect the PTT signal from the 705 against feedback/transients from the amp.

Assume from what I have read is that the amplifier will detect the TX frequency and switch in the correct filters.

Been looking at the Ameritron ARB-704 to handle the PTT line, however cannot find one for sale. Any other suggestions.

Thanks

Re: PN of the FDM-S3 TCXO and OCXO.

Vianney Colombat
 


I'm not an expert on this matter so I will give you the information I have.

TCXO version has a SMD TAITIEN TT Crystal Oscillator with these Phase Noise parameters:
    - 100Hz : typ. -130 dBc/Hz,
    - 1kHz : typ. -145 dBc/Hz,
    - 10kHz : typ. -154 dBc/Hz.

OCXO version has a PTH TAITIEN NI Crystal Oscillator with these Phase Noise parameters:
    - 1Hz : typ. -95 dBc/Hz,
    - 10Hz : typ. -125 dBc/Hz,
    - 100Hz : typ. -140 dBc/Hz,
    - 1kHz : typ. -148 dBc/Hz,
    - 10kHz : typ. -152 dBc/Hz.

A fact to know is that for the choice of the S3 oscillator the important was to have in that order, a good accuracy, a good precision and then correct reception performances.

The internal 10MHz goes out of the S3 with a minimal conditioning circuit so its characteristics are not impacted. It is different regarding the receiver performance because there is an Si5338 which generates the internal needed clocks.

Vianney

Sorry I should have changed the title.

 

Hello Vianney, I have asked Elad twice about the PN performance of the TCXO and OCXO of the FDM- S3 without a response. Can you please help with this?

 

Many thanks

Re: Virtual receivers in FDM-S3

Of course. Even 4.

Is it possible to set up 3 virtual receivers in FDM-SW2 that allow simultaneous monitoring of 3 different frequencies via VAC.? For instance, I might want to monitor 50.313 FT8, 50.318 FT4 and 50.323 FT8 all with their own individual decoder.

 

Is this possible?

 

My FDM-S3 arrives here next week 😊

Re: Virtual receivers in FDM-S3

Conrad, PA5Y
 

Ah further reading suggests that the answer is yes.

 

From the SW2 manual, ‘In this way, the user can analyze more than one signal together’

 

Sorry for the BW.
