I have one of these and I'd be interested in what you find out. Did you
transmit into it by mistake?I'm pretty sure MFJ doesn't manufacture these but I
would contact their customer service and see what they say.73,Gary K9GS

Subject: [Elecraft] OT: Looking for schematic and troubleshooting info on
MFJ-223 VNA My MFJ-223 VNA took a dive (cause unknown). The SWR
readings are very high regardless of load. Has anyone found a schematic for
this thing? The manual also mentions an MCU reset switch, but I'm guessing
that's outdated. No such
switch.tnxWayneN6KR______________________________________________________________Elecraft
