MAP65 compiling

Dear Joe,
I have just a couple of questions about current MAP65 compiling status:
- Is MAP65 currently only working on Windows platform?
- Did you cross compile MAP65.EXE under Linux or directly on Win?
- What's your plan for a (beta) release of source code to play with?
After some work, with help from Roger W3SZ I have been successful to compile 
WSJT598 on Ubuntu 7.10 and I would like to do the same for MAP65, since I am 
planning to make some experiments on 6m JT65a.
Just for your knowledge, next month the Ciao Radio H102 direct sampling 
receiver with dual parallel input should be available, and I am curious to 
see if it can be used for dual polarization EME work.

Many thanks and 73s
Alberto I2KBD

Linrad-02.40

Hello All,

Linrad-02.40 can now be downloaded from
http://www.sm5bsz.com/linuxdsp/linroot.htm
with mirrors at
http://g7rau.demon.co.uk/sm5bsz/linuxdsp/linroot.htm
and
http://nitehawk.com/sm5bsz/linuxdsp/linroot.htm

I will leave home tomorrow for one month, perhaps
with occasional E-mail access.

sound card requirements?

All,

What is the preferred architecture for a linrad sound card? How 
effectively is it abstracted by OSS or ALSA?

My current card a  Intel Corporation 82801DB/DBL/DBM. This apparently 
does not support simultaneous input and output. I am not sure if this is 
a hardware, driver, or configuration issue. Does anyone have any 
information on this or other cards?

Thanks - Dan

linrad-02.39

Hello Leif i guess that Ermanno, IK7EZN has already tolt you, regarding the
bug that i found on last 02.39 release.
It's a minor bug, because all the rest seems to work properly.
When i try to change the freq. trough the arrows all crashes.
Otherwise if i do it, just writing by hand all is ok.

Challenges!!

Hi All,

Any interference that is not random can in principle be
modelled and subtracted. In real life it might be too 
difficult, but I guess there are man-made interferences 
that could be significantly reduced. Improvements are
also possible with random interference in some cases.

I think the interference fighting in Linrad can be 
significantly improved, but I do not want to work on
artificial signals where I try to simulate various forms
of QRM - mistakes are easily done so I look for real life
recordings of signals that are at the detection limit or
slightly below. 

Is there really nobody reading this who has problems in 
copying "the other station" occasionally? I have asked 
before, but still I have no recordings to work with.

Currently I am only interested in the traditional modes
CW, SSB, AM or NBFM. Here are a few examples:

1) SSB in white noise but with inadequate S/N. Rather than using
  a rectangular filter Linrad could use a filter that is shaped
  as the power spectrum of the signal.

2) Interference from TV transmitters on 50 MHz.

3) Lightening crashes on (low?) HF bands.

Flex 5000 and Linrad and ARRL EME contest

Hello, All,

Just a quick note to say I had a ball using the Flex 5000 with Linrad 
during the first leg of the 2007 ARRL International EME contest, just 
finshing a few hours ago.

I really liked the combination and put a brief set of pictures at:

http://www.nitehawk.com/w3sz/flex-linrad.html.

I haven't fully integrated the 5000 into my EME station yet so it was 
used for receive only.  But it didn't mind at all sitting on the table 
near my LZ2US amplifier ;)

I have only positives to report, no negatives ;)

See you in the second leg of the contest.  Now to get some sleep ;)

73,

W3SZ

Paper on MAP65

A paper on the MAP65 program has been placed on the 
Documentation page of the WSJT web site.  A direct link to 
the paper is:

MAP65 and 50 MHz

Hi all,
I am preparing the gear to try MAP65 on the ARRL EME contest on 50 MHz.
Checking the software I found that current version of MAP65 only 
supports mode JT65b (in use on 2m) and not JT65a, used on 6m and HF.
Joe, is there any chance to enable also this mode?

All the best
Alberto I2KBD

OT Information required

Hi All

Sorry its a bit Off Topic, but
I'm updating my web page with the release of Mandriva 2008 and
 Suse 10.3.

Leif if you could let me know if there are any major new features with
Linrad, and does anyone know whats happened to SDR-Shell ?
There's nothing at
http://ewp.homelinux.net/sdr-shell/
and from googling it looks like is been ported to QT4, but I havn't
been able to find the package.

TIA
