RE: [PSUBS-MAILIST] revelation

Hugh,
 
   I too try to keep my shipping of things to a minimum.
 
   The transducer for solids sell for $26.97 and this includes shipping...If we were to have this shipped to you, do you feel like trying to make one yourself with help? Its easier than you might think and I can show you how...in fact, there is a step by step set of instructions under "projects and photos" under "comms" and my name. Just scroll down in the pictures until you come across the parts layout then follow this frame by frame. Give this a read and let me know if you want to try this out...I need someone else rehearsed in how to make these should I stroke out or something.
    This two part molding plastic is neat to work with and enough is purchased in each order to make two transmitters so work with a friend who also need one, or use for other things.
 
    The hydrophone I can supply and it is lightweight and ships cheap.
 
    Take a look at the new but never sold hailer listed for $49.99. Its shipping is only $12.00. Or, wait to see how these operate at the convention and we can go from there.
    We will keep the shipping fee to a minimum and my time is free.

Hi David,  Sorry to be so backward but what is the capability of what you are suggesting.  Is this setup with the bullhorn capable of transmission between sub and surface?  If so, then what would you expect the range to be and what frequency would it operate at.  Seems a wonderful way to go but I want to understand fully what you are suggesting.  I’m a bit slow on these things.  Chs,  Hugh

To all:
 
  Ever heard of a marine hailer?
 
  These things are designed to allow bullhorn type communications from one's dry wheelhouse during rainy and windy weather to other nearby boats.
 
  Take the airborne bullhorn away and replace this with an underwater voice transmitter and also replace the returning pickup microphone with an HBH-2 hydrophone and you have a ready made underwater broadband communications unit!
 
  To make this even more appealing, some newer units are about he size of a new cb console and even contain VHF radios to boot!
 
  Go to ebay and just look at the Standard Horizon Matrix GX3000s Marine hailer and VHF radio. This is for a new unit and its $188.00 and this includes shipping!
 
  Too pricy?... boat yards frequently sell off new but old stock items to make room for incoming merchandise.
 
  Take the Cybernet CTX 100 Marine hailer and intercom also showed on ebay. This old but never sold hailer is going for $49.99 with a $12.00 shipping fee. This is its second such listing.
 
  These hailers run circles around anything I have thus far produced and some have extra desired features to boot...seems I am soon to be out of a job short the transmitters and hydrophones. I can live with this as It was my goal to inspire interest in passive sonar and underwater comms to the point that most subbers look into building or buying something. My goal I feel is soon to be met.
 
  If your not quite convinced, have a look at Alec's old stock but never sold Ray Jefferson in action at the coming convention. He has graciously allowed us to us it for the support vessel and this gives us a chance to run one thru its paces first hand.
 
  To anyone who buys any hailer, I will be here to aid in the construction of the voice transmitters and passive hydrophones or I can assist you in making them as these are not too difficult.
