Re: [Discuss-gnuradio] Fwd: Ais_rx

Hi Vladimir,

What are you referring to? If its:

3. Incorrect subdevice or antenna specification

see
http://files.ettus.com/manual/page_configuration.html#config_subdev
Hint: the light next to the connector leading to your antenna should be emitting a clear green glow.

Most likely is really that you don't pick up significant signal from any ships because your antenna doesn't work sufficiently well.
What kind of antenna do you use?

Best regards,
Marcus

Hello Nick

What does it mean?

I’m understand what parameters is are default.

Does something special must be write in command line?

i.e: $ ais_rx –XX –XX ….???

Possible reasons:

1. Inadequate antenna

2. No line of sight to transmitting ships

3. Incorrect subdevice or antenna specification
