Managed to install the 3 NLB-310 MMIC amps backwards. Which I was specifically hoping to avoid.
(They are the round black components — which amplify microwave signals.)

Finally completed my first meteor scatter contact during the Geminids peak, using 100W and a home made Moxon for 6m via MSK144. Seattle to Reno: just over 900km.
