That works, except
if you return to calling CQ. Now you are on the S&P’s
frequency. You are potentially going to interfere with
S&P station is searching for ANY station and is NOT
limiting themselves to the even or odd cycle. Therefore, if
you TX on their TX frequency and they choose to respond to a
station that uses the other cycle time, you will be
interfering with them.
I think the advise
still stands, lock your transmit frequency whether or not
you are Running or S&P.

P.S. For those who do
not know the terms Running and S&P: “Running” means
calling CQ, and “S&P” means Search and Pounce.
Now, that makes a lot of sense. Adding, since this is SSB,
not FM, the capture effect which traditional AFSK packet radio
depends on, doesn't apply. What I don't know is how well JT's
algorithms handle multiple colliding signals.
So, if you're hunting and pouncing, check the box to stay
put. If you're calling CQ, then by your logic you should
uncheck the box so that when the person responds, your Tx will
move to their frequency, which is presumably a nice quiet spot
for them, so they'd be more likely to hear you?
I am very
confused as well, so a spent some time drawing bubbles and
lines to figure this out. Does this make sense …
you call CQ and I am the only other person in the world,
we can both TX and RX on the same frequency. That works
because for the first 15 sec you are TX’ing and the next
15 sec I am TX’ing.
problem comes when you call CQ and Carl, with his mega
station, also responds. Since we are both on the same
frequency he will either over-power me or we will
interfere with each other and you would decode nothing or
I will over-power him.
Now, if we
all transmit on different frequencies, Carl transmits on a
frequency other than yours, and I transmit on a frequency
other his and yours, you will be able to see both of us.
Your band activity window will change color showing both
of us responding. You will be able to pick the better of
us two, Carl, by double clicking on his call. Your RX
Frequency window will then lock on to Carl’s TX frequency
the exchange will continue. I will see you chose him on
the next cycle in my band activity window which is a hint
to move on.
If you had
picked me instead, my RX Frequency window is locked on to
your TX frequency and the software will automatically give
the response immediately on the next cycle.
nutshell, if we all TX and RX on the same frequency, it
will be slug fest to get your attention. The stronger
station will prevail or no one will win. Does that make

heck does “73” mean? 73 is morse code short hand for
“Best Regards” used by Ham radio operators. It’s origin
goes all the way back to the landline telegraph days.

the box Hold
Tx Freq to
ensure that the specified Tx frequency is not changed
automatically when you double-click on decoded text or a
signal in the waterfall.
I am not sure but I think it keeps you from
"grabbing" the other station's frequency if you chose to tx
your own CQ
