[RFI] Noisy Display - Quiet DC-Dc Converter

[qrv at kd4e.com]

While testing a just-arrived TOBSUN 50W DC-DC Converter
(Model: EA50-5V, 12-24v In 5v out) I discovered it to be
RF-clean but the generic 12v voltage display in the
12v distribution panel (two accessory connectors plus
the voltage display - designed for use in a car or boat)
proved real RF-noisy.

Pulled the + wire to the display and everything else was
quiet.

Checked using a Tecsun PL-600 on AM-BC, SW, & FM-BC.
