My suggestion was not for the original installation, but as a
suggested fix after Ken’s troubleshoot appeared to pinpoint the

I agree Ken. Unfortunately, installation companies don’t have that
degree of technical prowess or care, they just go in, do a job as
fast as possible, and move on. The owner of the gas station would be
oblivious to the EMC concern.

Nice. Seems as if a simpler fix would be a set of directional
antennas for the gas station’s 915 MHz link, yielding higher
intentional signal and if the antennas are properly oriented relative
to the suspected interference source, diminishing the interference level.

Hi All,
I thought this interference hunt to a gas station price sign might be
of interest to the group.
