          What do DX RPT I/P O/P stand for

          DX is an amateur radio abbreviation for DISTANCE but in this context probably means DUPLEX. RPT means REPEATER

          I/P is for INPUT and O/P is OUTPUT

          Repeaters are used to extend the range of radio systens. A site, usualy on a hill [high] or mountain that has a good view of then area you wish to cover is chosen. On this site are a transmitter and receiver on 2 different frequencies. The transmitter and receiver are connected together so when the receiver receives some thing it is retransmitted by the transmitter but on a different frequency, sometimes higher and sometimes lower. Hence the I/P and O/P. The mobile or handheld has these frquencies reversed. This method of operation is called 2 frequency simplex. Simplex because the mobile station can either receive or transmit but not at the same time.

          Hope this helps or have I just confused you! It is secnond nature to me as I have been involved in the radio game all my working life, since 1964 in fact!!

          PM me if need to and I will anwser any question you may have.
