Walt,

    I can't cite the reference right now, but Heath sold a mod kit to
replace the stepped "coarse" and variable fine loading controls with a
triple 365 pF air variable cap. Sounds like yours is equipped with the
mod, which IMHO, is a much better arrangement. Heath also published a
grid-block keying mod which seems to work FB in my DX-100.
