SCHEDULE 13D

This Schedule 13D relates to Common Stock, par value $1.00 per share (the “Common Stock”) of RadioShack Corp., a Delaware corporation (the “Issuer” or the “Company”). The address of the principal executive offices of the Issuer is Mail Stop CF3-201, 300 RadioShack Circle, Fort Worth, Texas 76102.

This Schedule 13D is being filed on behalf of (i) Standard General L.P., a Delaware limited partnership (“Standard General”); (ii) Standard General Master Fund L.P., a Cayman Islands limited partnership (the “Master Fund”); (iii) Standard General OC Master Fund L.P., a Cayman Islands limited partnership (the “OC Master Fund”); (iv) P Standard General Ltd., a British Virgin Islands business company (“P Standard General”); (v) Standard General Focus Fund L.P., a Delaware limited partnership (the “Standard Focus Fund” and, together with the Master Fund, the OC Master Fund and P Standard General, the “Funds”); and (vi) Soohyung Kim (“Mr. Kim”), a director of the general partner of the general partner of Standard General. The persons and entities referred to in items (i)-(vi) hereof may be collectively referred to herein as the “Reporting Persons.”

Standard General serves as investment manager to each of the Funds and, in such capacity, exercises voting and investment control over securities held for the accounts of the Funds. Each of the Reporting Persons disclaims beneficial ownership of the shares reported herein except to the extent of its pecuniary interest in such shares, and the inclusion of such securities in this report shall not be deemed an admission of beneficial ownership for any purpose.

(b) The business address of each of the Reporting Persons is c/o Standard General L.P., 767 Fifth Avenue, 12th Floor, New York, NY 10153.

(c) Each of the Funds is a private investment vehicle. Standard General provides investment management services to the Funds and other private investment vehicles.

The Common Stock of the Issuer reported herein as being beneficially owned by the Reporting Persons were purchased using working capital of the Funds.

Any funds used by the Reporting Persons to purchase securities of the Issuer in furtherance of the agreement described in Item 4 below will also be drawn from working capital of the Funds.

The information set forth in Item 4 below is hereby incorporated herein by reference.

Standard General has been in discussions with the Company regarding a proposal on a business operating plan and certain ways to improve the Company’s liquidity position in advance of the holiday shopping season. Proposals under discussion include Standard General and certain other investors (the “New Investors”) purchasing loans and other commitments under the Company’s asset backed credit facility (the “Credit Facility”) from its existing lenders. Under such a proposed transaction, Standard General and certain other New Investors may propose to subordinate their investment in the Credit Facility to other investors in order to improve the near-term liquidity available to fund the Company’s holiday working capital needs. Pursuant to such a proposal, the investment by the New Investors could be the first step of a broader recapitalization of RadioShack proposed to be completed by early 2015, which may include Standard General and certain other New Investors acquiring preferred equity convertible into common equity, board nomination rights and corresponding changes to the Company’s structure. The New Investors have provided draft financing commitments to the Company to fund such a transaction. Discussions are ongoing among the Company, the New Investors, and the existing lenders under the Credit Facility. No assurances can be given that the proposed transaction will occur, or in the form currently under discussion.

The Reporting Persons reserve the right to change their purpose and to formulate and implement plans or proposals with respect to the Company at any time and from time to time. Any such action may be made by the Reporting Persons alone or in conjunction with other shareholders, potential acquirers, financing sources and/or other third parties and could include one or more purposes, plans or proposals that relate to or would result in actions required to be reported herein in accordance with Item 4 of Schedule 13D.

(a) and (b) See Items 7-11 of the cover pages and Item 2 above.

(c) The Reporting Persons have not effected any transactions in the Common Stock during the sixty day period prior to the filing of this Schedule 13D.

(d) Not applicable.

(e) Not applicable.

The Reporting Persons hold options to acquire an aggregate of 3,000,000 shares of Common Stock at a price of $1.50 per share, which options expire in January 2016. Standard General has entered into a confidentiality and standstill agreement with the Company. Pursuant to this agreement, Standard General has agreed that until June 12, 2015, neither it nor its affiliates will propose (except in the context of consensual negotiations) any acquisition, restructuring, recapitalization or certain other transactions relating to the Company or its affiliates, or engage in certain other activities relating to an effort to obtain control of or influence over the Company’s management, Board of Directors or policies.
