[Linrad] Re: WSE / Delta44 / Linad / MAP65 Windows local host setup

Hello Randy,

> Does WSE/Linad/MAP65 need to swap I&Q when using M-Audio's cable?
No. (But in case I and Q would need to be swapped a better idea
would be to change the sign of fg.passband_direction. This would
be done by adding your own users_hwaredriver.c and compile.

I never used the Linrad/MAP65 combination myself, but I know timing
is essential for decoding. I hope someone else will help here:-)

Hmmm, the section on "running Linrad" on the Linrad Home Page is
getting old (Written 2001) and very much information is missing.

Some day I should rewrite this part and add those windows
(freq control and several more ones) that are missing.

The way Linrad is intended to be used first time is like this:

1) Press F1 on the main menu. (Keyboard commands)

2) Press F1 on the receive screen with the mouse on an
empty space. This will show all mouse controls.

3) Investigate the controls (all of them) by placing the mouse
on them one after the other, and press F1.

4) When any of the help texts does not make sense, post
a question to this mailing list.


Help is also available in the parameter setting menus, 
place the mouse on the line of interest and press F1.

??????????????
You do not need this to run Linrad. Use it in case you want
to use the WSE units with Winrad.

In Linrad-02.53 you can select any address by setting the last
number in the address =-1. That will make Linrad read the file
par_network_ip for a single line of text with an IP address.
