Re: Ft-301ad blinking s-meter no transmit

 

Yes, there is no continuity between K1 and K2 when the power is on.

I think I'm misunderstanding something. From what I can see on the block diagram, the LPF unit is like a gateway between the PA and then antenna. The relay on the LPF unit needs to be closed in order to transmit. For some reason on this radio the relay is open, which is the root of the problem. I thought by bypassing the relay and just jumping K1 to K2 it would essentially take the LPF unit out of the mix and the radio would transmit. This doesn't seem to be the case. So I think I'm misunderstanding what the LPF and blanking units do.
