Dear Jim,

ufb copy " M0BMU M0BMU JASON92 " on 135918, now at 23:30.

As a late reply to your posting of Jan 24th (still catching up after a holiday):
... The Jason signal is equivalent to 17 separate QRSS stations on different frequencies, using a funny type of
arranged so that only one station is transmitting at any one time. So the ability to detect this kind of signal with a given signal power and noise power spectral density only depends on the length of the dots and not at all on the number of frequencies used. ...
...not quite, I think. When searching the maximum amplitude in more channels,
the statistical probability of a high noise peak in one of them becomes
larger, and the error rate increases. Otherwise, one could transmit any
number of bits using only a given amount of energy.
