Re: [linrad] Linrad Shell script and network connection



Linrad can be set up to operate remotely. Leif configured it to do this in early 2003, in version 00-55.

To use it this way you need to be running Linrad at the remote site, and connected to the receiver.

You then ALSO run Linrad on another computer at the other end of the network, and you can listen and operate the Linrad program there as though you were receiving the signals directly.

I tried this before I got all of the Linrad Hardware hooked up [I think it was nearly 2 years ago], and so I don't know if the WSE hardware switching [for changing band segments,etc] works from the computer at the other end of the network from the hardware. I would think that it doesn't, but I haven't tried this and probably won't try it anytime soon due to time constraints. But Leif knows and will comment I am sure, and I DO know that receiving at the other end of the network works fine. At the time I measured and recorded the actual NETWORK bandwidth requirements using some Linux utilities designed for that purpose, but I have lost the results...

I hope that is of some help.

Has anyone done a shell script to install Linrad and all the other components?

Also, why not use a network connection to get the data from a receiver into software? I was thinking of using a network card and a micro to drive it. You could have the receiver remote from the PC, connected by CAT5 cable. Also the Rx could be streamed on the net.
Has anyone tried this?

Data rates would probably be higher than with USB - in theory USB rates are high but with many so called USB2 compliant devices it is apparently quite difficult to raelize the theoretically possible rate. I posted this question a week or so ago but my E mail has been down - may have missed some replies.
Apologies if this is the case.
