The proper sequence of a JT65 QSO (at least on HF).

Assume I see VE3ODZ calling CQ and I engage in a QSO with him it would run something

like the following;

CQ VE3ODZ FN03 1 – VE3ODZ is calling CQ

VE3ODZ W6CQZ CM87 2 – I answer VE3ODZ with my call sign and grid

W6CQZ VE3ODZ -13 3 – VE3ODZ answers my call with a report (-13)

VE3ODZ W6CQZ R-08 4 – I acknowledge my report (R) and send his (-08)

W6CQZ VE3ODZ RRR 5 – VE3ODZ acknowledges my report (RRR)

VE3ODZ W6CQZ 73 6 – I end the QSO with a 73

W6CQZ VE3ODZ 73 7 – VE3ODZ ends the QSO with a 73

That's it. The 'perfect' JT65 QSO. Call signs exchanged, locations (grids) exchanged, signal

reports exchanged and confirmed with R- and RRR and lastly QSO ended with the 73

messages.

Messages 6 and 7 could be replaced with free text messages, for instance I could send 10W

DIPOLE 73 (and would ID with CW ID if I had it enabled – which I should since that would

meet the [USA] legal requirement that I ID with my closing transmission. If I sent the standard

73 message the CW ID would be redundant since I sent my call sign in the message itself).

You could also use the shorthand RRR for the 5

frame and the shorthand 73 for the 6

and

, but, please remember that JT65-HF does not decode shorthand messages if the

multiple decoder is enabled. This is due to the time required to run the decoder. Evaluating

for shorthand messages can almost double the multiple decoder cycle's time requirement. It

really only makes sense to use the shorthand sequences when working at the absolute lowest

limits of JT65's detection ability (signal of -25 or less).

The example above is essentially all you can do with JT65. You can't send a 'brag tape' or

convey War And Peace with it, but, you can complete a minimal QSO at often very very weak

signal levels using low power and sub-optimal antennas. In comparison to other modes JT65

allows doing things with relative ease that would be impossible or very difficult. The price paid

for this extraordinary weak signal capability is its restrictive 'vocabulary'. For many of us that

is a small price to pay and not being able to have a rag chew QSO is worth being able to have

an 'impossible' QSO.
