[TransAtlantic] Welcome Message to Trans-Atlantic Remailer

it would be great to see a copy of N7BHC's presentation.

to start a discussion,  I am not sure Horizontal polarization is optimal for a crossing. If water evaporization is a component of the path, vertical may be more optimal. I am looking at the impact of the pseudo brewster function over salt water to maintain a signal that may stay within 10 meters of the surface for long distances. A potential path woud be composed of evaporation and traditional ducting.  My marine vhf radio propogation work at 156 MHz was all vertical with  25 watt radios, 3-6 dbd antennas less then 30' Many Bermuda, Bahamas,Puerto Rico, etc receptions from Hatteras over the years... 
Thoughts?

Hello Friends,
Thanks for subscribing. Please let anyone know about this remailer that you feel 
ould be interested or have something to contribute. They need not be hams. I'm 
ure we'd love to have a transatlantic airline pilot with an interest in VHF 
istening subscribed, or maybe some DXer's that monitor the TV and FM bands for 
ransatlantic signals. This remailer was an idea before a reality for a while. I 
ope it helps get a signal recieved across the Atlantic.
Most of all we need subscribers from both sides of the Atlantic, and South 
merica and Africa, and from all the islands in between.
We are up to 15 subscribers in 1 day. Bob, K4ESA is the first subscriber to test 
he remailer a few minutes ago. And, congrats to Dave, N7BHC, for being the 
irst subscriber only 14 minutes after the annoucement was sent out yesterday! 
ex, W4DEX was a close second, only 1 minute after Dave. At last April's South 
ast VHF Society Conference, in Charlotte, NC, Dave made 2 different 
resentations, both on subjects relating to transatlantic VHF communication. His 
alks were voted as the best of the conference. So, as shown by Dave's talks, 
hen it is presented to the VHF/UHF ham community, the subject of a possible 
ransatlantic qso is interesting to quite a few weak signal enthusiasts.
Scientific theoretical, predicted, and actual propagation disussions and 
bservations will be welcomed on this remailer. For example, a subject like, 
How different propagation modes might work together to complete a path from 
orth America to Europe", would be a very good one.
This remailer will probably not be very busy, unless some propagation starts to 
appen. Interestingly enough, if you take a look at William Hepburn's North 
tlantic map for yesterday, Tuesday, Nov., 10th, the first day of the remailer's 
xistence, with the exception of a very narrow distured area mid-way, there was 
redicted an area reaching across of mild enhancement from the Southeast US 
oast to Spain and Portugal.
Initially the list is set at a maximum message size of 20kb. That will let you 
nclude most original messages in a reply, if desired. But, you might want to 
ut off some of the longer original messages in a lengthy reply.
Please listen for the transatlantic beacons:
A1ZMS, FM07fm, Virginia, west of Lynchburg, 144.285
7BHC, FM15pa, Oriental, Pamlico County, NC, (about 60-70 miles south west of 
ape Hatteras), 144.291
4MHZ, FM25df, Hatteras (town),near Cape Hatteras, NC, 144.300
