I understand that in the United States, amateur operators and even non-licensed persons may participate in domestic (and approved international) communications on bands they wouldn't normally be allowed to transmit on, using the privileges of another licensed ham who serves as control operator.
As a concrete example, I hold an Extra Class license and my 7 year old son has a Technician class license. He wants to help me solder up the new Omnia SDR Proficio HF transceiver kit that should be arriving tomorrow. Once it's assembled, I'd love to let him try it out too — but his privileges don't cover digital work on any of its bands except 10m. I'd like to help him try some bands with better propagation, but am not sure the etiquette for properly identifying between our two call signs.
What would be the proper way for him to identify himself, and me as the control operator, during a digital QSO? To use an extreme example, could he call CQ with his own callsign during a JT65 exchange and mention mine only at the sign-off? In a slightly less constrained mode like RTTY/PSK, is there a standard format of identifying both the privileged licensee/operator, but also any "third party traffic" participant who may or may not have their own callsign?
Further, if he were to make a successful contact, would it be appropriate for him to log these QSOs as his own? I don't mean in a "station log" sense, but rather the contest-oriented sites like ARRL's Logbook of the World or eQSL, where contacts can count towards various awards and such? Since technically I would have been the control operator, would that be considered poor sport for him to count it under his own callsign?
