One transistor transceiver

My attention was brought to this design yesterday. 

My immediate thoughts were than the TX would be fine, but the RX very deaf. For local QSOs and experiments fine, but it could not be seriously used as the RX would not be able to hear who is on the channel. If the other station TXed first, you would know the channel was clear.
