Default Re: Communication Receivers and Speakers

I rescue the small self-contained speakers from mobile phone hands-free car kits as we have a lot to dispose of at work. They are similar to the "communications speakers" available for amateur radio and often have an impedance of 4 ohms, which work well on communications equipment and some even have a 3.5mm jack plug already fitted! The audio quality is poor for normal domestic radio but just right for comms. It's worth saving the electret mics from these kits also, and as most people seem to change their mobile phone, (and hence car-kit) regularly these days, spares are plentiful and cheap.
