Transmit only.
Night circuits, raining, in a DR1050, with nav lights, beacon, and, on final, landing light, the battery was losing charge. When I reported downwind, I was told " Report final".
The Edo-Air had a switch, biassed to "transmit", which was held on "receive" when the transmit button was not pushed. It remained on "Transmit".
After several "Final, request touch and go" calls were unanswered, I started saying " Final, full stop, transmitting blind". The landing light was useless, and I landed, cleared runway, and taxied to hangar, reporting my position "blind".
When I phoned the Tower, they'd heard all my transmissions, and had given me a "green", which I didn't see, concentrating on landing. In the circumstance of "Report final, number one", ATC approved my decision to land and clear runway.
