Re: minimum distance over water to qualify reception as TP/TA?

Good afternoon,,,
 
In one of my clubs, they have defined Trans Atlantic loggings by island names.
 
For North American listeners, you can include the Azores, Canary Islands, Iceland, Madeiras Islands, United Kingdom, etc.
 
For European listeners, you can include Greenland, Bermuda, Puerto Rico, any of the Caribbean Islands, etc.
 
 Hope this helps.

I would think any transmitter within a country boundry would not qualify as TP or TA. Would Puerto Rico qualify as TA from the US?... Hmm what about Cuba?

All those stations listed are within US bounds.

A TA or a TP has to have the signal actually cross the majority of the ocean. Thus Iceland is a TA; Newfoundland is not. Japan is a TP, Catalina Island ( if there were any transmitters there ) would not.

Hi all. Is there a minimum distance over water to qualify reception as TP or TA? Or does just about any distance count (so long as you don't wade out into the surf with your radio and count stations on land as TP/TA - you, at least, have to be on dry land)?

For example, if any distance counts... then could someone in the Bronx count WFAN-660 and WCBS-880 as a TP, as their transmitter is on a small island? Or, would a little more distance be necessary?

As a few examples... 540 WLIE Islip, LY, 690 WADS Ansonia, CT, 1100 WHLI Hempstead, NY, 1240 WGBB Freeport, NY, and 1580 WLIM Patchoque, NY, all go over a portion of the Atlantic Ocean to get to Brick Township, NJ.
On the coast of Maine, for example Portland, ME, and to the east, it looks as if 590 WEZE, 680 WRKO, 850 WEEI, and 1030 WBZ, all from Boston, MA, cross the Atlantic.
In Charleston, SC, 550 WAYR Orange Park, FL, and 600 WBWL & 690 WOKV from Jacksonville, FL area, can be heard from over the water.
Would those stations possibly count as TA stations, or does a greater distance need to be spanned, or is there some other definition?

As for TP stations... where I live, KNX-1070 Los Angeles, KZER-1250 Santa Barbara, KZSB-1290 Santa Barbara, KCLU-1340 Santa Barbara, KIST-1490 Santa Barbara, KVTA-1520 Port Hueneme, KDB-93.7 Santa Barbara, and KVYB-103.3 Santa Barbara all go across the Pacific Ocean some significant distance (as a percentage of the total path) before I receive them. Also many of the San Diego and Baja AM stations can be heard in Santa Barbara, CA, as well.

Also, KBRT-740's transmitter is on Catalina Island. Does that count as a TP for us in Southern California on the mainland USA?

Also, what about reception of 780 KNOM and 850 KICY Nome, AK, on the east coast of Russia? Would those possibly be counted as TPs from there? Or is the distance too short?

Basically... does the target have to be on a different land mass AND a different country to count, or can you count something from the same country and/or same land mass if by virtue of the coastline's curve and the great circle path at least partially going over a piece of the ocean?
