Re: Intermittent QDX transmit failure on one band

Yes, exactly. The toroids are the ones to worry about.
The 47 uH molded inductors suffer in a different way. They are a bit brittle and are subject to physical damage. That too can shut down an LPF by denying PIN diodes their required forward bias current.

Thanks John! I'll start with those.
Just to be clear, when you're talking about checking the inductor leads first, you mean the hand-wound toroids (L2-L4, L6, L8, L10)? As opposed to the L1, L5, L7 and L9 radial inductor components?
