The output of the IC is ok. The problem is with the two switching transistors.
I dont know why they are using 2 NPN transistors to switch the relay !!
There is a diode between them. I dont like the way they did it. I tried 2 2n2222.
I had to re-arrange the leads. now, when I key, it hangs !!? They are just switches so it should be simple.
since I have to work with what I have here, I will try a 2n2222 (NPN) and drive a 2n2907 (PNP). That should do it, I hope.
I am working on two ft301 at the same time. :))?
