This is specifc to THOR. ???????????????????????????? 0 msec risetime???????????????????????????????????????????????????????????????????????????? 4 msec risetime 4 msec leading/trailing edge is similar to a CW signal.

SWL Tobias All Messages By This Member #37647 Hello David, Thanks, interesting option. Is there an expected effect on robustness worth testing or 'just' the bandwidth influence? Note: The Tooltip in Config still shows the text of the selection above it. 73s Tobias .-.-. Am Montag, 30.

Dave All Messages By This Member #37648 开云体育 Hi Tobias, I'll fix the tooltip.? I tested for Mid-Latitude-Disturbed NVIS 0 dB s/n; with 0, 1, 2 msec shaping.? Did not see any decrease in decode performance.? 4 or more msec will effect decode under stressful HF conditions.? The shaping does reduce the bandwidth for those situations where that is critical and signal is expected to be strong.
