[Elecraft] KX1 Please need help with T/R thump

[Jerry W7ANM]

Thanks Don,

Maybe were getting somewhere. Q7s base is at zero during receive but on
transmit it only goes to 0.1v.
The 6T_2 voltage on the other side of R28 goes from 0v during receive then
to 5.63v on transmit. (Normal?)

Looks like I will need to get another Q7?


Jerry
