[Elecraft] Lids running RTTY on the JT65 Frequency

OMG Joe! You are flat wrong here!
We all need to live together, this sort of thing is going to happen, so
get used to it. I have heard JTers lower than the allotted 2 KHZ they
have as a suggested frequency, and I don't consider them causing
intentional QRM, I consider them correctly using the spectrum allowed to
them. I will slide lower than the .76 and do JT as well, so does that
make me an intentional QRMer?
All of the digital subbands are suggested, not mandated, as you know.
You have a few impolite people transmitting on top of each other, mode
does not matter! That's all it is, impolite people not listening
improper to transmitting.
Because I find a clear, unused frequency, with no one transmitting on it
within a JT sub band, and I find a full sub band for RTTY, and transmit
there does not make me an intentional QRMer... It makes me an efficient
user of spectrum space.
I try and not do this of course, but to be honest during a contest if no
one is there and the entire RTTY sub bands are full, I will slide into
the JT subband, assuming there is a clear 200 hz., and I am not next to
someone. If I see that it is getting crowded in the JT bands, I'll
slide back out to leave some room for them... None of this makes me an
intentional QRMer. It makes me a polite used of the spectrum.
We are going to have to get away from all of the "this mode goes here,
and that modes goes there" mindsets... It wastes spectrum, as evidenced
by your reaction to RTTY in the JT sub bands. THis is just like putting
little boxes in a drawer, and saying just red pencils go box A, and blue
pencils go in box B, and green ones go in a box C... Pretty soon you
have 3 or 4 pencils taking up the entire drawer with empty boxes.
