In 1981, a small U.S.- supported station called La Voz de Mosquitia (HRXK) went on air from Puerto Lempira, Honduras. The frequency was 4,910 khz — and it was plagued by interference from other Latin American stations in the 60 meter band. A good write up about the station can be found here. This recording was made in Washington, DC using a Hammarlund HQ-180A receiver. The plain QSL card shown here was signed by Reverend Landon Wilkerson, an independent Baptist Missionary, who spent seventeen years in Honduras with his wife and family helping the Miskito Indians.
