Tnx Bill, and for the QSO on 17m jt65a, well When I use up the 1500Hz at 14076
I
could see it not going over well, but just ask me to move that I'm use all of
the bandwidth for jt65a, but to say it exceeds the bandwidth for HF, just ask
me
to move thats all. I can handle that.
Thanks Bill

Hi Russell,
Not sure (I am not the lawyer in my family:) but suspect due to its signal rate
it is legal. I asked the question on the HF JT65 board but no definitive
response. ISCAT is 23 baud at 1500 Hz and JTMS is 1500 bps and the bandwidth
2250 Hz. You are correct that it may be more of an issue as to where in the
band
you were transmitting more so than the legality of its usage. I am not sure of
the advantage of ISCAT on HF, aside from perhaps on a scatter path to 10/12
meters and it is down 10 dB or so in sensitivity from JT65/JT8/JT2/JT4 modes;
albeit uses a 30 second sequence like JT6M. I have only previously seen it used
on 6 meters and above. Of course some people simply do not like the wider modes
in general, hence the inevitable controversy.
73,
Bill N9DSJ
