This is an example of a real QSO made by EA6VQ that could help
understand beginners the right procedure for answering a station who is calling
CQ via the Moon. (Please notice that the values of date, time, azimuth,
elevation, etc. shown are not the real values but the values when I recreated
the QSO from the WAV files in order to make this page)
In this case I knew in advance from the DX-News
page that S79HP EME expedition was going to operate on 144.144 MHz, always
transmitting the first period (even minutes), so I:
Tuned the transceiver to that frequency
Entered his callsign and grid in the corresponding input
boxes
Unchecked the "Tx first" box (as I had to TX
second this time)
Pressed the "Gen Std Msgs" to generate the
messages and have them ready to transmit.
Pressed also the "Monitor" button, and waited for
some signal.
.
After some time I began to see a signal in the "SpecJT"
window.
When the one-minute period was over, WSJT easily decoded the CQ
call of S79HP. So I:
Clicked with the mouse on the red spike (that corresponds to
the frequency of the JT65B Sync tone) and checked the "Freeze"
box. With this simple actions I told the program that I wanted it to
concentrate on decoding signals which Sync tone was right on that frequency.
Decreased the value of "Tol" to 50 (50 Hz). This
is like setting a passband filter of that width, so the program will not
take care of other Sync signals, even although you still could see them in
the SpecJT window.
Made sure that I had "Text 1" selected, that is
the right text to send when answering a CQ
Set the "Auto" to ON, so that the program would
initiate the TX and RX sequencing automatically.
After sending Text 1 during my transmission period, the programs
passed to RX mode and I could see a signal again on SpecJT.
Then, the program shown the new decode...and "bingo",
S79HP had received me and it was sending me the O report ("OOO"). I
selected the "Text 3" (RO) to confirm him I had received his
"O" report and at the same time send him an "O" report as
well. (Please notice that in EME it's not meaningful to use the RST report
because the signals are almost always too weak, so the normal is to exchange an
"O" report, meaning that both stations are capable of copying each
other.)
WSJT transmitted my "RO" message and then passed to RX
again. This time I could see the following in SpecJT.
And when the program decoded it I could see that S79HP had sent
"RRR" that is the message confirming he had received my "RO"
and so at this point the QSO was complete (An EME QSO is
considered complete when one of the stations receives the "RRR", not
before). I selected the "Text 5" (73) as a final courtesy message.
Although sending/receiving "73" is not required to consider the QSO as
complete but it's a common practice to send it once, after having received the
"RRR" from the partner station.
Sent the 73 message for only one period and selected
"Auto" to OFF in order not to transmit any more on his
frequency..
