Greetings from the Island of Puerto Rico !

Radioamateurs "Hams" know there is no other service like ours. No fraternity on earth has the power and magic to bridge culture, nationality, distance or disparate interests as Amateur Radio can do. Moreover, few other avocations offer the opportunity for public service, personal development, technological advancement, or for camaraderie and sheer excitement.

I am mainly interest in CW, DX, Satellites, Earth Moon Earth (EME), APRS, Packet, RTTY, PSK31, JT65, FT8, WSPR, ATV, SSTV, SAREX / ARISS and software defined radio experimentation.

The electrical supply at home and the radio room is provided by solar photovoltaics, batteries and inverters.

For paper QSL confirmation please send stamped SASE. Please no irc's.

I am the owner/trustee of several amateur radio communications repeater systems. The primary use of the KP4IA repeater system is to provide public service and emergency communications. This communications system is located in Mt Marquesa, Aguas Buenas, PR coordinated and operating in the frequencies of 145.370 MHz (-), 29.620 MHz (-) and 51.980 MHz (-) also the amateur television repeater system (ATV), 426.250 MHz (out) 439.250 MHz (in), 1.252 GHz(in). KP4IA APRS - MARQSA Digipeater in Aguas Buenas, PR and JAYUYA Digi in Jayuya, PR both on 144.390 MHz. The 2 and 6 meters repeaters are linked also the 10 meter repeater which is well known by local, US and foreign radioamateurs due to its sensitivity and world wide coverage between the eastern and western hemisphere. The KP4IA repeater can be heard world wide even in bad skip conditions. The users of this communications system are friendly and most of them fully bilingual. Every year tourists radioamateurs visit the island of Puerto Rico. From the San Juan metroplex area the KP4IA 2 meter repeater with easy acceses using hand held radio so feel free check in and welcome !
