"SHIPP LINND AZEZU L453 LEXAD L453 LAMER A554 PTA"

After New York Departure on 135.90 they will be handed off to New York Center on 128.30, then to New York Center on 133.50, then to New York Center on 126.02.
These 3 New York Center frequencies are covered by the "ZBW/ZNY/ZDC (JFK Area) #3" Live ATC radio. The handoff to 126.02 takes place as the aircraft approaches the LEXAD waypoint, which is pushing the limits of this radios range. 133.50 is also covered by the "ZNY ATL86/ZDC SIE54" radio and you can sometimes hear the handoff to 126.02 but won't hear anything south of LEXAD.
On this route via LEXAD.L453 the HF frequency assignment will be given by New York Center on 126.02 and not by ARINC in this case. There are no Live ATC radios with coverage of 126.02 in that area yet. (A radio covering New York on 126.02 would make a great feed as it covers the handoffs to the eastern Caribbean HF frequencies and would compliment the 129.90 ARINC feed mentioned above).
The New York Radio (ARINC) HF frequency will vary but 11396, 8918, 5550 are commonly used on L453. All 3 frequencies are covered by Live ATC radios (search the frequency to get the link). The first call will be over PAEPR, compulsory reporting waypoints on L453 are PAEPR, ONGOT, BOREX, LAMER.
The aircraft will switch back to VHF over the LAMER waypoint to Miami Center on 135.20, then to Miami 132.30, then to Santo Domingo on 124.30, then to Puerto Plata Approach on 119.00, then to Puerto Plata Tower 118.00. There are no Live ATC radios I'm aware of with coverage of Miami Center in this area, there is/was one that coverd Santo Domingo but it seems to be down lately. (Search SDQ).
