You can always make a fresh installation with this command:
del par*.* (Windows) 
or rm par* (Linux)

It may be a good idea to do 
copy par*.* C:\linrad\old-parameters\datexxyyzz (Windows)
or cp par* /home/linrad-old-par/datexxyyzz (Linux)
before you delete the files so you can get your old installation
back easily. You must be logged to the linrad directory when
doing this.

A Linrad installation has everything in its own working 
directory. You may have any number of such installations
in the computer. The data files, .wav, .raw, .gif and the
EME data base reside at fixed locations.

OK. Any difficulties reaching so far?

This is the first cruicial point. Can you recall better
what your idea was and from where you got it?

This is quite a bit further along the path....

Hmmm, where are you now?

No, this is entirely a Linrad thing. I am not sure at
what point you are, maybe a fatal error.

???????
The message should be "Could not read file par_netsend_ip"
followed by what IP address Linrad will use.

Only delete par files:-)

Well, I know next to nothing about networking so I
can not say anything about that.

Yes, so far fine:-)

The 239 series is for multicasting and it is the IP address
used by Linrad as default. Those packages can be picked up 
on every computer on the network regardless of the IP address
of the computer itself.

Yes. Then Linrad will work fine:-)

OK. Good:-)
