A friend in South Africa has obtained a marine MF radio but can't=20 find any info. He says it's a Redifon G474, but the Internet has=20 nothing to say on that subject, so perhaps it's known as something=20 else. Here is his description: "It is a Redifon G474 emergency transmitter which covers from 400kHz=20 to 2.182MHz.=A0 It is a 19" rack mount type.=A0It apparently operates off=20 24V DC and has a pair of 6146s in the final.=A0 The exciter is solid=20 state and the driver seems to be a BFY51.=A0The metering includes PA=20 current and antenna current with a thermocouple ammeter.=A0I am told it=20 runs 100W on MCW and 100W pep on AM.=A0 The modulator is solid state=20 with the usual anode-screen modulation. Redifon was absorbed into=20 Thompson-CSF and then Thales so a bit difficult to get any data on=20 the equipment." Does anyone recognise this?
