VHF CC General Rule 4a:
"The contest exchange consists of at least both callsigns, RS(T) signal 
reports followed by a serial number, and the IARU locator. Particular 
contests may require additional information to be exchanged as described 
in the individual contest rules."

IARU Region 1 VHF/UHF/Microwave rules do not explicitly require exchange 
of both callsigns, but elsewhere the Region 1 VHF Managers' Handbook 
defines that:
"A contact between stations on VHF/UHF/Microwaves can only be judged as 
having been complete when have been exchanged
- Both Callsigns
- The signal reports
- Confirmation of reception of the above."

A similar definition is used for ARRL VHF+ contests, and in all cases 
this is a trickle-down from the minimum requirements for valid meteor 
scatter and moonbounce QSOs.

Once again, I am not setting this up in opposition to the standards that 
apply on HF. They're just different rules that only apply in their own 
territories.
