I have a new mobile which is set up for Vox Vara_FM ..
The issue is the VOX start-up and engage into TX is not quick enough for the vara_FM repeater .
If I manually PTT it is all working fine so all is working ,just the time latency for mobile voxPTT to enable , which is about 500-800 ms.
With this is there any way to configure Vara_FM server side to allow the delay .
All tests to server for AUTO-TUNE work well on audio side but no consideration of latency is availible in the system .
Most radios have slightly different VOX latency PTT .
Thanks in advnace

There is no way due to programming OCX limitations. You can move other ports above #16 and leave space for VARA FM port below #16.

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.

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??

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.

Russ, AA2GS
8 December, 2020 at 17:45
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
8 December, 2020 at 17:22
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

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
15 August, 2020 at 20:15
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?
15 August, 2020 at 20:06
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.

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.

7 October, 2019 at 14:33
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

7 October, 2019 at 14:20
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”.

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.

Hello Curtis,
You need to do an exclusion to C:\VARA folder in Windows Defender.

I have downloaded and uncompressed the VARA HF files. Run the setup as an administrator. I finally was able to find the .exe file, however that file gets erased or deleted when it is opened. Any ideas? Running Win10 pro on a Surface and HP desktop same thing happens on both computers. RMS express is the latest version.
Thanks.

Apúntate al VARA google group. Ya se están haciendo pruebas con la versión de VARA FM: https://groups.google.com/forum/#!topic/varahfmodem/0Mcplhmr-Vw

Intentaré hacer pruebas porque sería muy interesante reinventar un packet 2.0 mejorando con respecto al FSK 300bd.
Por cierto con Winlink funciona perfectamente, enlaces con VE y USA desde EA sin ningún problemas y a velocidades razonables incluso con S/N negativo.

Hola Rafael,
Supongo que sí que es posible, ya que lo que se hace al fin y al cabo es enviar información de A a B.

¿se podría utilizar este modem para construir una red packet radio con aplicaciones como ui-view o digipiater, etc??. Podría ser interesante por su eficiencia con niveles de baja S/R

Hugh,
It’s a false positive, not a virus

VARA does not work. It has a virus.

Yes, it is a modification

A question to the respected author is that in a frequency range of 40 meters there are 52-channel OFDM with Symbol Rate 41.6 bps in channels and a frequency shift of 46.8 Hz. Is this a modification of your VARA HF modem?

It’s a false positive

Lo probe desde Bolivia y funciono en 20m via Bern. Conecto en la primera, excelente, ahora por lo visto no hay buenas condiciones y veo a la mayoria en 40 m pero no tengo antena para ello, Felicidades

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.
1 November, 2017 at 10:48
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 😉
