[NLRS] EME contest score at N0AKC

[John (JK) Kalenowsky, K9JK]

Charlie, (but To: the list in hopes that this will be an "educational" 
dialog)

First, Congrats on the EME effort!

Now, for the (hopefully) "educational" part...

Never having played with JT65 myself but having played with PSK31...isn't 
there a "Graphic" display that gives some indication of signal presence? 
Maybe it's not 'real-time', though, like the "Waterfall" display I remember 
from the PSK31 program that I used.

Also, from what I've read/heard about the WSJT Programs (in the JT modes), 
isn't there also some ability to AFC, i.e. the program will both find the 
signal within a given bandwidth AND adjust itself (such as for doppler), 
primarily by tracking the ONE of the "tones" (the synchronization tone) that 
is present for an equal number of "bits" as the number of "bits" in the 
message itself?

The biggest potential problem that I can imagine would be trying to 
distinguish two stations that were transmitting on or about the same 
frequency, likely with similar received signal strengths...did you have any 
experience with that? Or is that NOT a problem?

73, JK

Jon,

The easiest way is to go on the JT65 EME link on ping-jockey and set up
skeds.  Many stations get on there and post where they are calling CQ, so
either you go to that freq and call them, or set up a sked with them on
line.

However, you would be amazed at how easy it actually is to hear the tones
coming through the speaker.

Charlie, N0AKC

Charlie, how do you initiate a contact, or  respond to a CQ, in a EME
contest
where everyone is running JT65 ?  Can you  "see" a station calling CQ
contest
on random, or do you have to hear them  to "lock on" ?   I thought you had
to
know the other stations freq to  make a JT65 contact (unless you can hear
them).
