Re: Automatic switching of speaker signals

Robert,<p>Thanks for all the detail. As an electrically challenged mechanical engineer, I do need a bit of further explanation.<p>The audio out from the radio will have two wires coming from the RCA plug. My reading of your post is that I'd put one of the those wires in series with a 10K resistor an...

Re: Automatic switching of speaker signals

Jolly Roger,<p>You've answered my question about knocking the audio output down to a level the VOX circuit can handle. Here's the kit I bought.<p> http://www.hobbyengineering.com/H2244.html <p>It's similar to the link you provided, but it includes the ability to set the delay on switching back to th...

Re: Automatic switching of speaker signals

Edd, <p>I bought that kit 30 minutes ago! If I'm feeling brave I'll pull the cover off my radio and see where the squelch circuits are, if not I'll use the kit.<p>I like the idea of not using the mic since I don't want conversations in the cabin to be inadvertantly blasted over the cockpit speaker. ...

Re: Automatic switching of speaker signals

Externet,<p>Beautiful solution. Simple, and lets me use the existing squelch dial to control nuisance noise rather than real radio traffic! Thanks.

Re: Automatic switching of speaker signals

Thanks for the advice guys. The VOX sounds like just the ticket.<p>To be clear, I'm not putting the emphasis on the music. On the boat I'm very much a "safety first" guy. In fact, right now I simply don't listen to music while underway on the boat, so that I can hear any VHF broadcasts. I also have ...

Automatic switching of speaker signals

I have a sailboat that has a VHF radio and a CD player. The CD player has stereo speakers in the cockpit so I can hear the music while sailing. The VHF radio does not, and I can't hear it when the motor is on (and I can't even hear it well enough in the cockpit to understand the broadcasts when the ...
