Power converter too close to radio?

[pchast]

Could the power converter's shielding be at fault? Are you certain of your
power lead's grounding? The converter's grounding?

No updates, I haven't done any changes yet. The radio in on it's own breaker.

If the radio is 12 VDC, it has a fuse, not a breaker. The breakers are for 120VAC distribution.

Have you called Progressive Dynamics and asked for guidance? They are in Michigan
A choke " an inductor used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC). A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a donut-shaped "bead" of ferrite material strung on a wire. The choke's impedance increases with frequency. Its low electrical resistance passes both AC and DC with little power loss, but it can limit the amount of AC due to its reactance" might help.
