The report contains the results of technical tests performed on the FAA Long Distance VHF Communications System at Palmer, Puerto Rico. The system capability is analyzed and discussed in terms of sub system per formance and some related meteorological factors. Results of the tests indicated that the significant rate of signal attenuation was 13.4 db per 100 nautical miles and the associated average usable range capability was 517 nautical miles. Some basic meteorological factors are correlated with communications data. Recommendations are made to terminate experimentation at the Palmer, Puerto Rico, site. Should consideration be given to place the Palmer system into operational status, modifications utilizing a specific equipment arrangement and corrective action are to be initiated prior to such course of action.
