[@manuellagasca5159]

di po pwede. sa mga nabanggit ko lang na brands dahil yon ang may Voltage sa speaker out

[@lynndelarea9970]

sir try to use optocoupler pc817 instead 2n2222 for ptt switch

[@manuellagasca5159]

I tried that once. But it cannot switch all the base radios. 2n2222 has higher current capacity. Optocoupler is best when isolation is concerned. But it does not make sense, since they have a common ground. There is no isolation involved in this design.
