Wiring external speaker Icom VHF radio

[bromleybysea]

I have been fitting a new external speaker to my Icon VHF. TheVHF set as a phono socket at the rear of the unit which an external speaker plugs into. The lead from my speaker does not have a phono plug so I was going to eliminate these and solder the wires instead. The lead from the speaker is a single conductor in a braided outer. But the Socket on the Icom has two seperate cables both with a single conductor inside a braided outer. Only one of these when connected inner to inner and braid to braid to the speaker cable works. What's the other one for?

To switch off the internal speaker-the one actually in the radio, when using the external one?????? I am only guessing though

Which model of Icom VHF do you have? The external speaker socket is usually a 3.5mm jack not a phono.

Are you sure the phono is the speaker....It might be the GPS input to radio. What radio is it????

I don't think you can get switching phono sockets. If it is a jack plug and socket then it may be switching.

If it is a single socket on the Icon it won't be a phono socket. They are single pole devices.

Of course it's a Jack socket, silly me. Don't think the spare wire is a switch, at least it doesn't seem. To do anything of you close the circuit. Thanks for the replies. Even stupid questions get a considered answer here!

On a few Icoms I've see the other jack fly socket is 0183 in. As for your connection, just pop a jack on the new speaker cable, when plugged in cover it with non adhesive heat shrink to stop it coming out but still make it easy so slice the heat shrink off if needed, it's a method I use a lot on nmea 0183 leads having originally getting the idea from Icom.

On most Icoms the 3.5mm speaker jack socket is also used for the programming/cloning cable. On the 3.5mm stereo type plug, the tip is for the speaker connection and the ring is for the cloning connection. Be careful what you connect to earth or short - it is not a switch.

Some Icom DSc sets have two flylead connectors. One is phono for the GPs nmea to the radio and the other is standard 3.5 jack which takes any bog standard extension speaker from Dixons etc
