Hi Joe .....i love the new +2khz button works very well
big pat on the back for that innnovation
Your speed in compiling new svn commits is amazing! Happy to hear that
you like the new "+2 kHz" checkbox.
On another matter, the question of startup default frequencies:
After receiving a bunch of input from the wsjtgroup reflector, as well
as off-list, I've concluded that the best frequencies are probably these:
Band JT65
--------------
160 1.838
80 3.576
60 5.357
40 7.076
30 10.138
20 14.076
17 18.102
15 21.076
12 24.917
10 28.076
6 50.276
For narrow-band, JT9-only operation, add 2 kHz. (That's what the new
checbox is for, of course.)
Regarding 30m: I've inserted what might be called a "software notch
filter". If you try to transmit in the WSPR band, the program will
refuse and pop up this message:
"Please choose another Tx frequency.
WSJT-X will not knowingly transmit
between 10.139 900 and 10.140 320 MHz,
the 30 m sub-band for WSPR transmissions."
This enforces a small "hole" in the WSJT-X displayed portion of the 30m
band, set aside for use by WSPR. Rather conveniently, it's located
between the JT65 and JT9 segments: from 1900 to 2320 Hz on your WSJT-X
waterfall. (The blanked-out width is 320 Hz -- the 200 Hz width of the
WSPR band, plus the 177 Hz width of a JT65 signal, plus a 20 Hz guard
band on each end.)
Comments???
Any reason not to make a second (and possibly final) beta release of
WSJT-X Version 1.1 ?
