RE: [PSUBS-MAILIST] revelation

Jim,
 
    Console #8 was to be the best I could produce in the way of size anyway, but internal wiring that was too small in gage has proven its downfall. I guess this was a bridge too far.
    It has not been decided what Alec and I will do for a plan "b" for his boat, but we will come up with something.
    As for your system, we could either ship it on to me at: David Bartsch
                                                                               2625 Highway 45 South
                                                                               Henderson, Tn.
                                                                                           38340-7016
                                                                                   or a better option
   You can work with me to produce the broadband voice transmitter there as these are really quite easy to make. I will show you how and where to obtain the parts needed. I would build the HBH-2 hydrophone and ship this on to you. Either way is fine with me. Seems you and Alec's surface Ray Jefferson units are the best of the best now.
   To get an idea of how one is made, go to projects and photos under UW COMMS under my name and page down until you get to the step-by-step instructions. Read these over and you should get a rough idea of what this would entails.

Hi David,

Best Regards,

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.
