This week I fired up my Nova X-PAK strobe along with an SL40 Comm radio.
There was a strong sound of the strobe power supply recharging its
capacitors coming through the radio. One problem was the strobe power
supply was not properly grounded. The power supply base is well anodized
and I had to sandpaper off the anodize around the ground points. Anodize
forms an excellent electrical resistance.
Also, I had connected the strobe cable shield to the "black" wire coming
out of the strobe connector, but it turns out that this wire is some 100
ohms off ground. Grounding the shield to the aircraft frame eliminated
all but the faintest sound in the headsets.

Finishing a second set of canopy side skirts (somebody else on this list
suggested getting a near-perfect fit on the canopy frame, and I second
that suggestion before fabricating the skirts)
