More importantly, if you conformal coat one of our boards, don't be
surprised if the RF performance changes.  Different coating materials
have different dielectric constants, none of which are the same as
air...  That will impact things like how the filters tune.  But, since I
haven't ever actually coated a TeleMetrum or TeleMega board (just things
we've built for AMSAT), I don't know how much effect there might be.
