Hi
Dave
I can?t remember if
it has an official term, 3 second Dots, 3 second Dashes. Dashes above a centre
line, Dots below, Space on the centre line.
In a way the 9
seconds for a Dash in QRSS3 is wasteful, particularly since it can break up
and appear to be 2 Dots.
Likewise the inter
unit space is wasteful, this lead to Castle Morse which climbs in frequency
for each Dash and descends for each Dot. This in turn is wasteful of bandwidth
and difficult to read. Which lead me to develop Step Morse which steps
up and down above the centre line for a Dash and below the line for a
Dot.
As far as I know this
has been very little used, however, blow me the Bloodhound read it
allJ

500KHz-WSPR-QRSS3
Hello
Eddie
Very interesting tests but what is "3 level QRSS3 with
equal Dot and Dash lengths" ?

Yesterday I increased
my TX power on 500KHz by 10dB so as to expand my coverage, maybe the QRPp 13uW
ERP has reached its limits.
