And why are you using tin as a shield?
Just needing clarification so the multitudes will know what they're getting.

Shielding of this type of device is required due to the high gain of
AGC amplifier. This AGC amplifier can have gains up to 60dB at low
input levels. Without proper shielding... this amplifier would
oscillate (squeal) like crazy. VoiceMax has a solid tin shield
covering all electronic components... as well as a solid copper pour
(shield) on the non-component side. Hope that answers your question.

Partially yes it does answer my questions and thanks for that.

What about modifying the cb radio that your kit would be improving?
Would this not be adversely affecting the legality of the now modified
radio? Of course this question would be null and void if you were
designing your kit for amateur scenarios. So how does it fly with the FCC?
