    Hi,

    Maybe you are running another application using the 8300 port.

    Ask in the Winlink forum:

    Hi, I recently purchased Vara modem and have not been able to get it to initialize correctly. While starting Vara FM, I keep getting the following message: Could not connect to VARA FM Command Port 8300 Connection failed: No connection could be made because the target machine actively refused it 127.0.0.1:8300. Any help would be greatly appreciated. Thank you.

    I have a windows 10 computer and have installed Vara HF. The computer is connected to my Yaesu FT 950 through a Rigblaster Plug and Play USB interface. When I select the Vara HF session and before selecting “Start” my transmitter turns on. I have not forund a way to prevent this. When I run other digital modes such and PSK 31 all works well. Do you have any suggestions, Thanks for your help K0LMF

    Yes. The registered (paid) version works fine with Trimode here.

  10. José Alberto Nieto Ros Says:

    The free version of VARA works with Trimode perfectly. You have to ask in the Winlink group if you dont know how to configurate

  11. Larry Gage Says:

    The free version of VARA works well with Winlink Express, but does not work with Trimode. Do I need to upgrade to have VARA work on Trimode? Currently we’re just testing the gateway and were reluctant to pay the $70 until certain that it will work.

    Hello,

    VARA FM only does the PTT switching. You have to select the COM port number in VARA FM. If unable open Com3, the Com3 is not actived

    Hello,

    i use an FT847 + SCU17 ( USB Interface ) to work fine in FT8/FT4 with WSJT-X.
    Com2 (enhanced) for Cat Control and Com3 (standard) for PTT-Control the intergrated SB in/out.

    Now my Problem:
    The same Configuration i want to use by Vara-FM, but Com3 will not accepted:
    “anable to open Com3, maybe in use by other application”??

    But it is not used by any application.
    Supports Vara-Fm (and Vara HF ) only enhanced Com Ports??

  15. José Alberto Nieto Ros Says:

    Yes, the license allow simultaneous instances and simultaneous computers

    Jose

  16. Dean Groe Says:

    Does the license allow for multiple simultaneous instances of VARA FM on the same computer?
    Such as one instance on a VHF channel and one instance on a UHF channel. I currently have it setup that way in evaluation mode and it is working OK. Of course some features are not available and I am limited on speed.

    Thanks

  18. Russ Connors Says:

    I am a user of VARA HF modem.
    I recently added anti virus/malware program called WEBROOT and it is blocking Vara Chat. Best Buy store tech says I have to disable WebRoot in order to use Chat. Do you recommend a better solution? By the way….we love Vara and Vara Chat.
    Russ, AA2GS

  19. José Alberto Nieto Ros Says:

    Jonathan,

    VARA does change any parameter of your rig. You have to read the Icom 7600 manual and learn how select the ACC connection.

    Anyway, the PTT is configurated in the Winlink application, not in VARA HF. I think you should ask to Winlink.

    73
    Jose

  20. Jonathan Fox Says:

    Jose, the HF side of KJ6LV uses an Icom 7600 with a Microham Digikeyer II to handle all the audio and keying. The VARA software however, always forces the radio to disconnect and go to the USB connection rather than the ACC connection. Is it possible for you to allow us to select the proper connection through the radio software? Thanks, Jonathan

  26. José Alberto Nieto Ros Says:

    John,

    The RA Board uses a special command using low level USB programming. It’s not COM, neither CAT, neither VOX. It’s not possible to do PTT in Winlink, unless the Winlink programmer does changes.

    Try with BPQ of John Wisemman.

    Jose

  27. john KC5LAA Says:

    Winlink Express does support VARA HF, but must use a sound card. The DRA-30 (not the DR-30) sound card connects fine to to VARA HF, but apparently uses COM port, CAT command or VOX for PTT. My question is how do I do that?

  28. José Alberto Nieto Ros Says:

    John,

    RMS Express does not support the DR-30. So, you only can use DR-30 with VARA FM.
    However, if you use BPQ with VARA HF, then you can use the DR-30.

    73, Don, KM4DC

  37. José Alberto Nieto Ros Says:

    Hi Don,

    In Winlink express->VARA FM setup, you have to replace the “127.0.0.1” IP adress by the new IP adress (where you are running VARA).

    But i think you must open VARA manually. Better ask in the Winlink group.

    For the Vara modem, you show 11 different speeds. Can you provide what SNR the speed changes at. Specifically I am interested in whether the Vara modem will operate in a negative SNR condition.

  57. José Alberto Nieto Ros Says:

    Hola,

    En radioafición, aunque fuera de 200dB no vas a notar ninguna diferencia, ya que el ruido radioeléctrico y la distorsión del canal es infinitamente mayor que el propio de la tarjeta de sonido. Cualquier tarjeta de sirve de sobra

    saludos

  58. Pirat3 Box Says:

    Es mejor para VARA una tarjeta de sonido con mejor SNR? He visto que algunos equipos como el FLEX o ICOM traen incorporadas unas tarjetas bastante pobres (pcm2901) con un SNR bajo, de 89DB y he visto otras tarjetas mas profesionales como algunas Sound Blaster que traen un SNR de 116DB y en definitiva, todo bastante mejor, como la “respuesta de frecuencia” o la “distorsión armónica”.

  67. Peter Knol Says:

    I did ask a om here in my area to instal Chat + VaraSAT. He, PA4GB (also QO100 active) has the same problem. TCP led stays red. No communication. Today I did switch all virus scanners off, but also no luck…

  68. Peter Knol Says:

    I did delete all VARA stuf. After reinstal and start Chat, Windows Defender Firewall asks if it is ok that VaraHF gets acces to network. Same happens when I start VaraFM. That Windows Defender Firewall does not pop up when I start VaraSAT. Looks like it does no request to acces the network. But I will focus at firewalls and virusscanners now…

  69. José Alberto Nieto Ros Says:

    maybe your antivirus have blocked TCP connections in VARA Sat

  70. Peter Knol Says:

    Yes. Vara Sat. I will reinstall the software. On a 2nd computer where the results the same. I did on both computers that ‘ virus check over rule ‘ thing. Map C:/VARA. I’ll try again…

  71. José Alberto Nieto Ros Says:

    Peter,

    have you installed VARA SAT?

  72. José Alberto Nieto Ros Says:

    Here it’s working perfectly. You have to check if the path is right

  73. José Alberto Nieto Ros Says:

    Ok, after i will test it at home

  74. Peter Knol Says:

    I tried such befor. I tried port 8400. Did not work. I just tried 8320. Still no TCP connection. When I hit Connect I get the message ,VARA Chat is not connected with VARA modem, !

  75. José Alberto Nieto Ros Says:

    Then there is a conflict with TCP ports. Select 8320 port in both VARA SAT and VARA Chat. Then try again

  76. Peter Knol Says:

    Yes. In Chat i select Varasat. No TCP connection but modem starts o.k. Works fine when I select VaraHF modem. Then led TCP is green. PATH TO varaSat is ok, otherwise it wil not strar the modem…

    In Vara Chat setup you have to select “vara sat”.

    Gracias Alberto, he estado mirando de que se trata el sistema Winlink. Lo he puesto en modo automático y cada cierto tiempo emite la señal e intenta conectarse con la estación Gateway a ver si le voy cogiendo el truco. También he puesto un mensaje de prueba en la bandeja de salida del correo. A ver si se conecta y lo consigue enviar.

    Hola Carlos. Para manejarlo primero tienes que estar familiarizado con el sistema Winlink. No se trata de un modo tipo QSO.

  116. Carlos Gascón Saso Says:

    Saludos a tod@s. He descargado el programa VARA y lo tengo ya instalado, pero hay unas cuantas cosas que no entiendo muy bien, a ver si me podéis explicar un poco.
    – Cliente y gateway
    – Hay que colocarse en alguna frecuencia específica como en Ópera o en Ros???
    – Etc…
    Si me podríais explicar un poco para poder empezar a manejarlo, aunque sea por encima para hacerme un poco a la idea de su funcionamiento.

    it’s not my development. The commercial version of VARA is already in this site

    I see very similar signals outside the amateur bands. But the OFDM segment of the modem has differences – 60 channels with a speed of 40 bps and a spacing of frequencies between them of 50 hertz. In this connection, the question for the respected author is – tell me, this is one of the versions of your modem, maybe commercial, or it’s just a coincidence and it’s not your development.
      The records of the 60 channel modem are available via the link:

    Así funciona la cosa Roberto, por eso dudé si subirlo a internet o dejarlo guardado en el disco duro.
    En Marzo me llega un toroide de ferrita y tendré operativa una estación EMCOMM en 30m con VARA. De momento lo tengo provisional en 10 metros.

    Gracias por tu trabajo, muy bueno por cierto.
    Ayer pude conectar a HB9AK y con niveles ridiculos estuvo enviandome la informacion, de 10 la robusted del protocolo.
    Lastima de no ser Norteamericano, seguro que ya habia cientos de personas usandolo 😉
