I've found that hams are notorious for plugging in a multi pin
connector and not securing the connector to be tight with the provided
thumb screws. The "I'll do it later, but I've got to get it on the air
now" seems to always take precedence . The connectors will wiggle
and back out, often leaving an intermittent connection.
Likewise with PL-259 connectors. Finger tight is simply not good enough
for a reliable RF connection. I use a pair of 4" Channel lock pliers to
snug the PL-259 connectors. And I solved many RFI issues for others
just by tightening the PL-259's in the path.
