ABSTRACT:
A simplex radio-accessories interface connector (30) connects the simplex radio (10) having a speaker amplifier (102) and a push-to-talk (PTT) detector (103) to accessories which include an earpiece speaker (107) and a PTT switch (110). The connector (30) has a first connector mating assembly (25a-d and 84a-d) for coupling the connector (30) to the radio (10) and a second connector mating assembly (44a-c and 48a-c) for coupling the connector (30) to the accessories. Inside the connector (30), a receive audio line (104a) couples the speaker amplifier (102) to the earpiece speaker (107) and a PTT detect line (122) couples the PTT detector (103) to the PTT switch (110). At the second connector mating assembly (44a-c and 48a-c), the receive audio (104a) and the PTT detect (122) lines are combined (44a and 48a).
