Folks,

I've posted my initial drop of the WSPR beacon code for Penny 
in:  svn://64.245.179.219/svn/repos_sdr_hpsdr/trunk/PennyWSPR 
There's a README file at:
svn://64.245.179.219/svn/repos_sdr_hpsdr/trunk/PennyWSPR/README.txt 
This code turns Penny and an Excalibur into  a standalone WSPR beacon.

WSPR is  a weak signal propagation reporting tool.  Information on it 
is at:http://www.physics.princeton.edu/pulsar/K1JT/wspr.html

There are two variations of the code posted, one that beacons on a 
single frequency at a time, and one that beacons on multiple 
frequencies at a time.  The single frequency version is the most 
practical. the multi freq once is the most gee whiz, but not as 
practical since it splits the available power over a the frequencies 
being beaconed..

To use this code on the air you'll need to rebuild it to have your 
call and grid square.  See the readme for details on how to do 
this.   If you want to just kick the tires on it,  you can load 
PennyWSPR.pof from SVN  and run into a dummy load and watch on 
another radio with WSPR (turn or spot uploading for this).  Power up 
Penny at the top of an even minute and you should see it beacon on 
40, sleep 2 mins, beacon on 20, repeat.  The beacon preprogrammed into it is:

         PE0NNY AA00 23

I've been running the single tone version on 40 and 20 meters to a 
low wire dipole from a barefoot Penelope (200 mW out) and have seen 
it spotted from Canada to Venezuela

Have fun with it.

Cheers,

Bill (kd5tfd)
