ANt pol - H / V

2009-11-08T21:22:21Z

MessageHy all
What i must do if i have 90 deg Phase between my H and V dipol an the ant boom ?
What is the right parameters that Linrad knows the phaseshifting between the antennas ?
for example - M²´ 2M28XP

Hi Carsten,
I do not remember. It is written somewhere in the MAP65 documentation.
Well, I have no experience with that. I would verify by checking
dt from MAP65;-)
The unit that needs calibration is the RX2500. For I/Q balancing
it does not matter if you send the signal into 2.5, 10.7, 70 or
144 MHz. Use what is convenient - but connect both channels.

That's the answer. There is usually a menu item (in KDE at least) for
system information that tells you what processor you have amongst other
useful stuff - also the "hwinfo" command and if you are still unsure, a
google search will reveal whether the reported CPU is 32 or 64-bit.

Hello Leif

Tnx

I know that the cables OK , but will check them again.

what is the right level ?

The time in Linrad is the same as in MAP65 - same PC - .
- sync by Dimension 4

What is the way to calibrate the WSE and the filters ?
What level the WSE need for calibrate ?

I thing we have running a very good system but used only 10% from it

Hi Carsten,

Maybe the cables are crossed somewhere....
Besides having the correct signal level into MAP65 you must also
have the correct time. Maybe WSJT searches in a slightly wider range
of time offsets than MAP65. Look for the time of those transmissions
that decode and make sure they fall well within the search window.

Hi Chris,
Yes:-)
The problem was to know what libraries to look for with the
configure script.
Linrad can use optional packages but they may be
difficult to install for newcomers. Therefore the configure
script will give informative (hopefully) messages about
what options that could be added.
For Linrad-03.09 they are:

Isn't that simply telling you if the OS is 32 or 64 bit? You can have 32 installed on a 64 bit platform.

Or was that the original question?

Hi Ken and Pierre,

Yes. Thanks. I verified this on my Xeon system with 64 bit Suse.

Hi Ken and Pierre,
Yes. Thanks. I verified this on my Xeon system with 64 bit Suse.
I feel a bit uneasy about this method because when there are changes in
the 64 bit architecture in the future, maybe the -m would report someting
else....

Polswitching from H / V Antenna

2009-11-02T08:05:12Z

hello all

I use a system with 8 times 14ele XPol antennas.
I use Linrad 0308 in weak siganl CW and WSE
Setings for POL is:
0
+
Auto
H

Channel 1 - horizontal
Channel 2 - vertikal

now Linrad calculated the pol 90 deg wrong !!!
I checked with TS2000 and WSJT and the signals
from the WSE / Linrad with 90 deg are all only on hori.

Leif:

I'm certainly no serious programmer, so maybe this is not what you want:

uname -m

I only have 32 bit systems here, so it reports 'i686' on those (could
also be i386/i486/i586). My understanding is that 64 bit systems
return 'x86_64'.

Hi All,
Under Linux the Linrad configure script looks for various files
to decide which packages are installed. This works for 32 bit
versions of Linux, but when Linrad is compiled on a 64 bit
distribution the test for things like libXext.so which is done
like below may give a false positive.
LIBEXT=0

Hi All,
I have received this bug report:
The gcc compiler is changed now and then and it always becomes better.
I have not yet tried Ubuntu 9.10 myself, but obviously the latest
gcc (not yet included in Debian testing) has better error checking.
There is a serious error in Linrad. The array declared on line 22 in

Hi Alex,
The reason Linrad is so complicated, to newcomers is that you
have a lot of fredom to select what processing you want.
First, get an understanding of the block diagram.

MAP65iq on Vista

2009-10-27T15:50:20Z

I have MAP65iq_r11116 installed and running on a Dell laptop running Vista
Not really knowing what I am doing I plugged in my SDR-IQ and the
computer asked for a driver. I let it search for one and it found
and installed a driver and when I start Linrad in SSB and MAP65 I get
what looks like a normal waterfall.

Hi Leif,
thank you for the quick reply.
OK
I don't understand that,as don't know how to set Linrad to generate
wide banwidth.In this case it possible to use the output second
soundcard in first computer with Linrad.
I can do it ,when I meet Serge.
