<HTML><FONT FACE=arial,helvetica><FONT  SIZE=2>Hello group,
<BR>
<BR>there was nice signal from Jim M0BMU in the new promising WOLF BPSK mode on 
<BR>saturday evening (just got home from the club station with 30 megabytes of 
<BR>recorded audio..)
<BR>
<BR>I had 100% error free copy right from the start, even though there was heavy 
<BR>QRN (static crashes) and a lousy drifting receiver (about 0.5Hz in 30 
<BR>minutes) on this side, so a lot has to be improved here before I will be able 
<BR>to transmit a useful signal from DF0WD (sri). 
<BR>
<BR>Jim transmitted an unmodulated carrier of some minutes at the beginning of 
<BR>every TX interval, which allowed a kind of 'calibration' of the RX frequency. 
<BR>It also helped very much to find the center frequency, which must be passed 
<BR>to &nbsp;&nbsp;the decoding software as a command line argument.
<BR>
<BR>May I suggest a dramatically reduced power for the next test transmissions, 
<BR>so that also the EU stations can dig in the noise for a weak signal (let's 
<BR>say 1mW instead of 300mW), because with Jim's powerful signal was much higher 
<BR>than &nbsp;the noise floor on saturday. 
<BR>
<BR>So thanks again to Stewart (KK7KA) for the invention of WOLF and to Jim for 
<BR>his test transmissions.
<BR>
<BR>
<BR>73's from Wolf (DL4YHF).
