Hi all Saw nil from OM2TW,  but will look more carefully later.  M0BMU
was in all night with  the 7 freq format. Seems to take a lot of space
.  Why will it be better?

That is what I would also like to know. 7 fsk with tone spacing takes up
about 14 times more spectrum and is not compatable with others modes on
close adjacent frequencies, do not see any advantage with dfcw either
except that it and 7fsk are more noticeable on screen but that does not
constitute a better signal over noise transmission type or any advantage
over QRS which takes the minimum bandwith of all the modes to achieve the
object on a very narrow band.
A few nights ago someone was testing a data transmission around 135.920
khz taking up 500 hz of bandwidth, what is coming next !!!!!!!!!
While experiments with different modes are to be encouraged 136 khz is not
a suitable band with only 2 khz available, the only suitable mode for this
band is CW, normal speed and QRS.
Try the HF and VHF bands or Satellites where there is and abundance of
spectrum available for mode experimentation.

Valerio,  OM2TW  will be gone on vacation for few days .  Perhaps you
can transmit on 135.922 until he is back.  Best time seems to be from
0300 to your sunrise
   Let me know if you will be transmitting es I will look for you.
