The best digital DX reply
599, TU 73 de VE3FMC
End of transmission, in the log.
I don't operate PSK but when I do RTTY that is all I send. As long as the DX station has my call and report that is all I care about. He doesn't need to know what rig etc I am using, nor does he care when he is working a pileup. Same goes for CW or SSB, short and sweet.
Move on to the next one and let the next guy work the DX station.
That is what I like about JT65. Yes it is slow, but the exchanges are all the same, except for the text you can type in. Then you are limited to 13 characters with that.
Right now I have HNY GL2013 73 as my final transmission on JT65
If the DX uses LOTW, EQSL or direct, or whatever you will either get your card or you won't. If you need the country then send the DX station a SASE.
