Hello all. I'm looking for a service manual or alignment instructions for a Newmar Nav-121 DF radio. This one has a digital dial which is simply a frequency counter. The main board is the same as the analog radio with the make/models listed below.
Maricom RDF-501A
Models FR-662B by Coastal Navigator, Jackson, Maricom, Newmar, Sanshin and Rogers. Maybe more.
All these were made in Japan by Sanshin.
Anybody have the alignment instructions? Mine receives well but I'd like to check it.

Thanks in advance!
