Narrative:

Going south or R-763 we got clearance to deviate west of course up to 50 mi (by ny commercial radio) but because of the size of the line of thunderstorms we were forced to exceed the 50 mi we could not contact ny commercial radio or mia center due to static caused by WX. Once around the storms we went directly back to the airway. We advised mia approaching ground turk that R-763 was unusable due to thunderstorms. Supplemental information from acn 291809: when WX avoidance is required along atlantic non radar rtes obtain HF clearance early as af radio reception deteriorates near thunderstorms and cloud tops. Once outside of clearance area we did turn on all aircraft lights and climbed 300 ft off altitude as further traffic avoidance. Possibly should have squawked 7700 for military radar (if coverage in the area). Also, we increased airspeed to make our ETA at next reporting point. Once back in arid contact with ny commercial radio reported latitude long position and estimate on when we would be re-established an airway. Monitored TCASII in above, below and level modes so as to see any traffic similarly equipped -- none noted. Should have broadcast over carib frequency of 130.55 and 121.5 but in trying to get HF contact didn't think of it. Might have been able to contact aircraft operating in clear and announce position as well as relay to ny commercial radio.

Title: UNABLE TO ESTABLISH RADIO CONTACT DURING HDG TRACK POS DEV ACCOUNT ENRTE WX AVOIDANCE.

Narrative: GOING S OR R-763 WE GOT CLRNC TO DEVIATE W OF COURSE UP TO 50 MI (BY NY COMMERCIAL RADIO) BUT BECAUSE OF THE SIZE OF THE LINE OF TSTMS WE WERE FORCED TO EXCEED THE 50 MI WE COULD NOT CONTACT NY COMMERCIAL RADIO OR MIA CTR DUE TO STATIC CAUSED BY WX. ONCE AROUND THE STORMS WE WENT DIRECTLY BACK TO THE AIRWAY. WE ADVISED MIA APCHING GND TURK THAT R-763 WAS UNUSABLE DUE TO TSTMS. SUPPLEMENTAL INFO FROM ACN 291809: WHEN WX AVOIDANCE IS REQUIRED ALONG ATLANTIC NON RADAR RTES OBTAIN HF CLRNC EARLY AS AF RADIO RECEPTION DETERIORATES NEAR TSTMS AND CLOUD TOPS. ONCE OUTSIDE OF CLRNC AREA WE DID TURN ON ALL ACFT LIGHTS AND CLBED 300 FT OFF ALT AS FURTHER TFC AVOIDANCE. POSSIBLY SHOULD HAVE SQUAWKED 7700 FOR MIL RADAR (IF COVERAGE IN THE AREA). ALSO, WE INCREASED AIRSPD TO MAKE OUR ETA AT NEXT RPTING POINT. ONCE BACK IN ARID CONTACT WITH NY COMMERCIAL RADIO RPTED LAT LONG POS AND ESTIMATE ON WHEN WE WOULD BE RE-ESTABLISHED AN AIRWAY. MONITORED TCASII IN ABOVE, BELOW AND LEVEL MODES SO AS TO SEE ANY TFC SIMILARLY EQUIPPED -- NONE NOTED. SHOULD HAVE BROADCAST OVER CARIB FREQ OF 130.55 AND 121.5 BUT IN TRYING TO GET HF CONTACT DIDN'T THINK OF IT. MIGHT HAVE BEEN ABLE TO CONTACT ACFT OPERATING IN CLR AND ANNOUNCE POS AS WELL AS RELAY TO NY COMMERCIAL RADIO.
