Hi Dave,
Actually what you describe is EME reports as opposed to Terrestrial
reports.
The OOO and RO are used for EME but are also the defaults in so much
as the JT65 modes were initially mainly used on EME.
Either will constitute a good contact as long as RRR is exchanged. The
73 exchange is not required for either EME or Terrestrial
and is really just a courtesy.
Usually you will see new stations both in EU and the US using the EME
protocol until they have gained some experience
and or someone has explained how to send terrestrial signal reports.
Hope this helps.

There seems to be a difference btween reporting systems between the US
system and the European system on terrestrial JT65A contacts.
Can anyone explain to me when a contact is 'valid' between two stations
using the two different systems please?
For example, I received the following today (callsigns obscured to not
cause offence) on 20M
163700 12 -2 0.0 5 4 * CQ EA*** JM** 1 0
163900 10 -5 0.1 5 3 * G0DJA EA*** JM** 1 0
164100 6 -6 0.0 5 3 * G0DJA EA*** 1 0
164300 10 -15 4 3 RRR ?
That was it, no report, not even "OOO"s. I was using what, in the
guide, says is the European standard of sending the received dB signal
strength, but the EA station was using the US version, appart from no
"OOO".
A quick read through the excellent Bozos guide gave me the clue that the
other station was double left clicking on callsigns (US system
reports)and I am double right clicking (Eu system reports).
Now, two questions occur to me at this point.
1. Is my EA contact 'good' or 'incomplete' and
2. What's going to happen when US stations and Eu stations work each
other?
I wonder why two reporting systems were created for terrestrial JT65A?
My guess is that the US one will win out anyway, as that just seems to
be the way these things go and left clicking is more "the norm" than
right anyway, so why the alternative systems?
Also, whilst I'm asking questions, why does double right clicking
automatically turn Auto TX to ON? If you are not careful, and want to
pre-load a callsign to call at the end of an existing QSO, you end up
accidentally TXing over the top of the person working the station you
want to have a go at next. This seems a bit like poor operating and
it's not untill you do it for the first time that you realise what's
happening...
Thanks for any help with these problems I'm having - Dave (G0DJA)
Hi Barry......as far as i can tell the 73 exchange is still needed for a
complete contact.....
look in WSJT 6 Help "Examples of minimal JT65 QSO's" and both styles of
EME and Terrestial
are shown.....i understand there has been some talk about this with Joe
Taylor and his statement is that the minimal shown is the way that it
always has been on CW or SSB
some ops are very fussy about the 73 and ive had them send it several
times until they get a 73 reply.....
hope to work you one day on JT65A 20 or 30 m
