The noise was dominated by static crashes and impulses, rather than the usual neighborhood buzz. The decoding process was greatly helped by the "-b" blanker option in WOLF. Then I processed the file through a brick-wall limiter in Cool Edit. That worked even better. As I recall, the limiter was created by yanking up the limiter curve so that everything above -60 dB was brought up to 0 dB. Nasty sounding, I can assure you. I announced my triumph to Stewart, and then found to my dismay that the technique didn't work well on any other files than those recorded that night. Anyway, I will be running my Lowfer beacon in Jason mode all next week, and will be listening from 200 km away. That should provide a decent test platform. John Andrews, W1TAG
