This filing constitutes Amendment No. 6 to the Schedule 13D of the Partnership. The Partnership amends such prior Schedule 13D reports with respect to the common stock of Comarco, Inc. (“Comarco”) by adding the following information to the items indicated.

The sole general partner of the Partnership is Parsow Management LLC, 2222 Skyline Drive, Elkhorn, Nebraska 68022 (the “General Partner”). Alan S.

Pursuant to the Comarco bylaws, the Partnership intends to nominate Dr. William H. Evers, Jr., Alan S. Parsow and Sean T.
