[Moon-Net] NO 73s for a "valid" contact!

Conrad, and others,


IF 73’s are needed for a complete contact, most DX-pedition QSO’s are invalid, and quite some in the past with CW too.

Under difficult conditions, during piles and contest one don’t spoil time in the unnecessary 73’s.

I like to finish a contact with 73, but if it is clear to me that we have all details on both sides I count it as a valid QSO.

On HF with the many contests you will seldom hear a 73 in phone nor CW.

So simple is it!

73, Peter PA2V


(Still very happy with my E44CM 432MHz EME QSO)

Well actually the thread has been somewhat hijacked. The original poster asked if 73 was required for a complete QSO. 

The emphatic answer is NO this is well documented and not really worthy of further debate.

I then gave a few examples of real world EME behaviour to help illustrate how things work along with a message to listen and observe and figure it out for oneself.

On the subject of the logger and its use in the contest if 73 is not required for a QSO then passing thankyou messages after a contact is logged is irrelevant. 

The only competitive advantage that I gained by using the logger during the contest was for allowed frequency announcements and as an aid to staying awake!

I will take these issues up with the ARRL privately before submitting my logs. If I am disqualified for sending tnx wishes on the logger AFTER a qso is logged then so be it. 

I did the contest to see what my station is capable of, I have answered that to my own satisfaction. 

Final score 206 x 84 = 1730400
