sir di ba na dwn grade yun out put pwer nyo o masisira yun x'mit pwer pg nagtransmit with load.dummy or ant? clarify lang..

[@VhongRadioCommunication]

Masira ang transmit power kung contineous transmission na wala antenna pero kung saglit lang d naman...mas malakas makasira mag transmit ka ng untune antenna kasi mas malakas kumain ng current...kaya nasisira power output..

Sir paano po pagrepaire ng gm 300 mahina ang tapon ng signal ok naman recieve

[@VhongRadioCommunication]

Check mo muna power supply baka bumabagsak, kung okey naman check, Coaxial cable, connectors, SWR ng antenna mo baka wala sa tono sa frequency na gamit mo, kung okey naman possible mababa na RF power output radio mo need na palit RF drive/Final amp.

[@orlyyou1648]
