[VHFcontesting] Non meteor scatter digi modes in the Jan contest ?

[Marshall-K5QE]

Hi Patrick....I believe that JT65 is not allowed in the CW only portions 
of 6M and 2M.  So using 144.100MHz, the exact band edge, would not be 
allowed either.  I may be wrong on this.  Why these legacy CW only bands 
still exist is beyond me....

I still maintain that using the N0UK reflector(s) is the best way to 
find really weak stations.  I certainly am not going to spend two hours 
on terrestrial JT65 if I can make a sched, work the guy in 5min, and go 
back to MSK144.  Everyone knows about PingJockey and the EME-1 pages, 
but there is also a JT4/JT65 Terrestrial Link page that could be used 
for folks trying to find that really long one terrestrially.

It is true that there are a very small number of stations that do not 
have Internet access, mostly rovers way out in BFE.  With cell phone 
coverage the way that it is now, even most "way out" rovers can hit a 
cell tower.  Still, there is nothing wrong with having a "calling 
frequency".  We just all have to know what it is.

I'd certainly encourage others to do so... after all, it's made for digging really quiet signals out of the muck.  It's easily coordinated via http://on4kst.org/ or http://www.chris.org/cgi-bin/jt65talk.  Don't know why it's not more popular, given all the EME nerds using JT65 through antenna stacks and kilowatt amps between 144-1296 MHz.

To summarize my viewpoint, although just randomly squatting in the SSB segment is "okay," it's not optimal.  JT65 can pull out signals really close to the noise floor, so knob-spinning is not the best approach, and not everyone knows or can reach the web chat sites (for example, remote rovers).  Besides, it's a logical, well-established practice to have a calling frequency, QRG, call it what you want, as a baseline where you can park the radio.

And it avoids stepping on SSB users (CW folks are more audible, and can filter more easily).
