Sounds easy for Nikola Tesla.Yes, one can easily be fabricated such that when the VHF audio output is energised it will turn on a relay that will switch the speakers to VHF radio for a preset period of time. After not receiving VHF audio for 10 seconds, the relay timer will expire and the sterio speakers will be reconnected.
Haro.
I have an electrical engineering degree, it is easy for me. It takes few integrated circuits and components to design and assemble one. Since it requires no power supply and runs on 12vdc, I estimate less than $20.00 if I was making it for myself. This device may already exist to purchase as it is indicated by others.Sounds easy for Nikola Tesla.
I have two waterproof speakers I want to install in the cockpit, but I may not get a chance to do it before i leave on our crossing to Hawaii soon, too many other more pressing issues atm. Having the salon speakers duck would be nice if an emergency transmission came through.You'll most likely need some sort of amplifier to boost the output of the VHF. The 2-5 watt amplifier in the VHF wouldn't be able to drive all of those speakers very loudly and would probably fry after a few months.
Car audio amplifiers can be had for as little as $10 for cheap Chinese ones. This also might be a good opportunity to get a decent amp to drive those cockpit speakers. I'll try to draw up a diagram later today to better explain how such a system would work. How many speakers do you have in the cockpit? Do you want the salon speakers to switch to the VHF as well?
Good idea but I have one installed VHF, a back up unit, and a handheld, and don't want to/don't have time to order another radio before I sail out of this place.Wire in a remote station problem solved, that way you can talk, listen and change channel on the VHF radio leaving it independant of the entertainment system.

The station is not a complete unit, it is only a multi function microphone, able to scan channels, adjust volume, listen and talk. Sorry if you think that it was a crappy idea, but perhaps you should have opened the link, you would have then seen what I was talking about......Good idea but I have one installed VHF, a back up unit, and a handheld, and don't want to/don't have time to order another radio before I sail out of this place.![]()

Perhaps that is what is meant by the imogee's, thanks for pointing that out @dlochnerI think he was referring to getting out of Pago Pago, American Samoa.
