         Form 10-K for the fiscal year ended Dec. 31, 2004, filed March 16, 2005
         File No. 000-11685

Dear Mr. Spirgel:

I write in response to your review of our referenced filing and the comments
contained in your letter of March 31, 2005. We are submitting herewith a draft
of Amendment No. 1 to our Annual Report on Form 10-K/A (File No. 000-11685) for
your reference in connection with our responses to the Staff's comments below.

Item 8. Consolidated Statements of Operations, page 28 of the original filing
(not included in our amended filing)

1.       In response to the Staff's comment, please note that our revenue
         derived from services did not exceed 10% of total net sales during 2004
         or 2003. Our service revenue, as a percent of sales, was approximately
         2% and 4% for years ending 2004 and 2003.

Item 9A - Controls and Procedures, page 43 of the original filing, page 3 of our
amended filing

2.       We confirm to the Staff that our disclosure controls and procedures
         were effective as of the end of the period covered by our Annual Report
         on Form 10-K for the fiscal year ended Dec. 31, 2004. Accordingly, we
         revised the language in our amended filing as requested by the Staff.
         Further, in response to the Staff's comment, we have eliminated the
         "reasonable assurance" language contained in the original filing.



3.       We confirm to the Staff that our disclosure controls and procedures are
         designed to ensure that information required to be disclosed in the
         reports that we file or submit under the Exchange Act is accumulated
         and communicated to our management, including our principal executive
         officer and me, serving as principal financial officer, to allow timely
         decisions regarding required disclosure. Accordingly, we have revised
         the language in our amended filing as requested by the Staff.

4.       In response to the Staff's comment, please note that there were no
         changes in our internal controls over financial reporting that occurred
         during our last fiscal quarter that have materially affected, or are
         reasonably likely to materially effect, our internal control over
         financial reporting. As requested by the Staff, we have included this
         statement in our amended filing.

Signatures, page 49 of the original filing and page of the attached proposed
amended filing

5.       As requested by the Staff, we have added the signature of our Principal
         Accounting Officer in our amended filing.

We acknowledge to the Staff that:

            .   we are responsible for the adequacy and accuracy of the
                disclosure in our filing;

            .   the Staff's comments or changes to disclosure in response to the
                Staff's comments do not foreclose the Commission from taking any
                action with respect to the filing; and

            .   we may not assert the Staff's comments as a defense in any
                proceeding initiated by the Commission or any person under the
                federal securities laws of the United States.

Please forward any further comments or questions to me.

Very truly yours,

Malcolm Persen
Chief Financial Officer
Radyne ComStream Inc.

                                EXPLANATORY NOTE

     On March 16, 2005, Radyne ComStream Inc. (the "Company") filed its Annual
     Report on Form 10-K for the fiscal year ended December 31, 2004 with the
     Securities and Exchange Commission. This Amendment No. 1 on Form 10-K/A is
     being filed to make clarifications to Part II, Item 9A and to include a
     signature of the Company's Principal Accounting Officer. This amendment
     includes new certifications of the Company's Chief Executive Officer and
     Chief Financial Officer in accordance with Rule 12b-15 under the Securities
     Exchange Act of 1934, as amended. Accordingly, an amended Exhibit Index is
     included under Part IV, Item 15. Except as described above, no other
     information in the Form 10-K has been amended. This Amendment No. 1 on Form
     10-K/A continues to speak as of the date of the original Form 10-K, and the
     Company has not updated any disclosures to reflect events, if any, that
     occurred at a later date.

                                        2


                                     PART II

ITEM 9A. CONTROLS AND PROCEDURES

     Based on their evaluation as of December 31, 2004, our Chief Executive
     Officer and Chief Financial Officer have concluded that our disclosure
     controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under
     the Securities Exchange Act of 1934, as amended (the "Exchange Act"), were
     effective as of the end of the period covered by this report to ensure that
     the information required to be disclosed by us in this Annual Report on
     Form 10-K was recorded, processed, summarized and reported within the time
     periods specified in the SEC's rules and instructions for Form 10-K. Our
     disclosure controls and procedures are also designed to ensure that
     information required to be disclosed in the reports that we file or submit
     under the Exchange Act is accumulated and communicated to our management,
     including our Principal Executive Officer and our Principal Financial
     Officer, to allow timely decisions regarding required disclosure. There
     were no changes in our internal controls over financial reporting during
     our most recently completed quarter that have materially affected, or are
     reasonably likely to materially affect, our internal control over financial
     reporting, or other factors that have materially affected, or are
     reasonably likely to materially affect these controls subsequent to the
     date of their evaluation, and there were no corrective actions taken with
     regard to significant deficiencies or material weaknesses in our controls.

     MANAGEMENT'S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

     Management of the Company is responsible for establishing and maintaining
     adequate internal control over financial reporting as defined by
     Rules13a-15(f) and 15d-15(f) under the Exchange Act. Because of its
     inherent limitations, internal control over financial reporting may not
     prevent or detect misstatements. Also, projections of any evaluation of
     effectiveness to future periods are subject to the risk that controls may
     become inadequate because of changes in conditions, or that the degree of
     compliance with the policies or procedures may deteriorate. Management
     assessed the effectiveness of the Company's internal control over financial
     reporting as of December 31, 2004. In making this assessment, our
     management used the criteria set forth by the Committee of Sponsoring
     Organizations of the Treadway Commission (COSO) in Internal
     Control-Integrated Framework.

     Based on our assessment of those criteria, management believes that the
     Company maintained effective internal control over financial reporting as
     of December 31, 2004.

     KPMG LLP, the independent registered public accounting firm that audited
     the consolidated financial statements of the Company included in our Annual
     Report on Form 10-K for the fiscal year ended December 31, 2004, issued its
     report on management's assessment of the effectiveness of the Company's
     internal control over financial reporting as of December 31, 2004. The
     report is included in our Annual Report on Form 10-K filed on March 16,
     2005.

     Pursuant to the requirements of Section 13 or 15(d) of the Securities
Exchange Act of 1934, the Registrant has duly caused this Amendment No. 1 on
Form 10-K/A to be signed on its behalf by the undersigned, thereunto duly
authorized.
