Termination Insensitive Amplifier (TIA)

I recently put together a PCB for a termination insensitive amplifier, based on the original article by Wes Hayward, W7ZOI, and Bob Kopski, K3NHI. The general idea is to provide an amplifier that has an input impedance (usually presenting a 50Ω impedance) which does not depend upon the output load, and an output impedance that […]

Maytag MVW5430MW top load washing machine with F9E1 long drain fault

I have a 3 month old Maytag MVW5430MW top load washing machine that failed to drain and would stop at the “wash” setting. I ran the diagnostics mode on it and found it had a F9E1 long drain fault. The following table demonstrates how to read this diagnostics code: The first set of LEDs that […]
