Good afternoon, I have a super jopix 1000 (almost equal to ss3900) with the following problem.
The radio receives perfect in all bands, but no tx on any band. The led turn off from green when I try to transmit. Switching transistor (tr38) is OK when switching the micro to transmit. Voltage on tr51 collector is 0, and in tr 49 0 aswelk. I'm despite because led no switching to red. Which is the relation between both scenarios?. Any idea what can I try to see?
Thx very much
