W4JSI, Joe , In Athens, AL with VE5TLW , Terry, and
VE5MU , John, both in Regina, Saskatchewan established comminications
on
3584.5 about 2:30Z. stations are about 2200km
or 1200 miles apart. Many thanks to both Joe and Terry for
participating
Under noisy conditions , contact was made
initially on Contestia at 500hz/ 8 tones. copy was very rough. Then moved to
32/1000 and
communications improved.
The largest improvement came with moving to 32
tones/1000hz Olivia, with all stations enjoying 100% copy on very weak signals.
Gear at W4JSI was a FT-990 , VE5TLW, TS-2000. and
VE5MU , TS-480 all using MixW.
Olivia would be the mode of choice under these
conditions.
Other experments between VE5TLW and VE5MU came to
the conclusion that 4tones/1000hz Contestia would be the fastest practical
speed on HF.
this mode setting would produce just over 15
characters per second.
This should be tested over a longer distance since
both stations are in the same city.
I'm up for more testing , especially on the lower
bands.
