  The HONORABLE JOHN W. PECK, Senior United States Circuit Judge for the Sixth Circuit, sitting by designation.
  JOHN W. PECK, Senior Circuit Judge.
  Austin Jerry Hux appeals from a guilty verdict in the district court on two counts of manufacturing an electronic device which surreptitiously intercepts electronic communications in violation of 18 U.S.C. § 2512(l)(b) and two counts of infringing the copyright of computer programs contained in satellite descramblers in violation of 17 U.S.C. § 506(a). Hux appeals on three grounds. First, he contends that 18 U.S.C. § 2512(l)(b) is not applicable to the conduct alleged in the first two counts. Second, he asserts that the district court erred in admitting certain evidence. Third, he alleges that the evidence was insufficient to convict him of the copyright charges. For the reasons stated below, we reverse in part and affirm in part.
  I. BACKGROUND
  Hux sells and services satellite systems, two-way radios, and other electronic devices. In March 1989, an undercover agent working with the FBI asked Hux to modify a General Instruments VideoCipher II Satellite Descrambler Module so that it would receive premium pay channels without the user paying the provider of the programming. Hux made the modification for $400. Again in May 1989, the undercover agent gave Hux a VideoCipher II for modification. Hux modified the second unit and was paid $400. The FBI analyzed the de-scrambler and found that a computer chip had been modified to allow the receipt of all encrypted channels. On the basis of this evidence, a search warrant was issued for Hux’s business, Fireball Electronics. Items seized during the search included modified computer chips, programs to modify computer chips, and the tools necessary to perform the modifications.
  Hux was indicted on two counts of manufacturing an electronic device for the purpose of surreptitiously intercepting electronic communications, two counts of copyright infringement, and one count that was dismissed prior to trial. Hux was convicted on the four counts presented to the jury. He was sentenced to three years of probation, six months of which was to be served in an in-home detention program. Additionally, he was fined $40,000. Hux appealed his convictions to this court.
  II. APPLICABILITY OF 18 U.S.C. § 2512(l)(b)
  18 U.S.C. § 2510 et seq. are commonly referred to as the Wiretap Law. Hux argues that as such 2512(l)(b) is not applicable to the alleged conduct of modifying satellite descramblers. His contention presents a difficult question of statutory interpretation that has caused a split of opinion within the Circuit Courts.
  A. Statutory authority
  The legislative history of 18 U.S.C. § 2512 as it was originally promulgated states that its statutory language is intended to “establish a relatively narrow category of devices whose principal use is likely to be for wiretapping or eavesdropping.... The crucial test is whether the design of the device renders it primarily useful for surreptitious listening.” S.Rep. No. 90-1097, 90th Cong., 2nd Sess., reprinted in 1968 U.S.Code Cong. & Admin.News 2112, 2183. Martini olive transmitters, spike mikes, and other microphones disguised as jewelry, pens, or cigarette lighters were specifically listed as prohibited devices. Id.
  In 1986, the existing law was amended through the Electronic Communications Privacy Act of 1986. The stated purpose of the amendments was to “update and clarify Federal privacy protections and standards in light of dramatic changes in new computer and telecommunications technology.” S.Rep. No. 99-541, 99th Cong.2d Sess., reprinted in 1986 U.S.Code Cong. & Admin.News 3555. While the original law covered only interception of oral and wire communications, the amendments added electronic communications as well. The legislative history lists many of the new telecommunications and computer technologies covered by the amendments including electronic mail, computer-to-computer communications, electronic bulletin boards, microwave, cellular telephones, cordless telephones, electronic pagers, pen registers, trap and trace devices, electronic tracking devices, and remote computer services. Id. at 3562-65. Interception of certain satellite transmissions by home viewers is discussed in the legislative history only in the context of excepting unencrypted satellite transmissions from the Wiretap Law under 18 U.S.C. § 2511. In fact, the legislative history states that “[t]he private viewing of satellite cable programming, network feeds and certain audio subcarriers will continue to be governed exclusively by [47 U.S.C. § 605] and not by [18 U.S.C. § 2510 et seq. ]. Id. at 3576.
  The amended provision under which Hux was charged, 18 U.S.C. § 2512(l)(b), imposes criminal sanctions on anyone who intentionally:
  manufactures, assembles, possesses, or sells any electronic, mechanical, or other device, knowing or having reason to know that the design of such device renders it primarily useful for the purpose of the surreptitious interception of wire, oral, or electronic communications....
  Hux contends that the proper statute for the alleged conduct is 47 U.S.C. § 605(e)(4) which provides criminal penalties for:
  Any person who manufactures, assembles, modifies, imports, exports, sells, or distributes any electronic, mechanical, or other device or equipment, knowing or having reason to know that the device or equipment is primarily of assistance in the unauthorized decryption of satellite cable programming....
  As noted earlier, the propriety of convicting a person who manufactures or sells modified descramblers under § 2512 has caused a split in the Circuits.
  B. Case law
  In United States v. McNutt, 908 F.2d 561 (10th Cir.1990), cert. denied, — U.S. -, 111 S.Ct. 955, 112 L.Ed.2d 1043 (1991), the Tenth Circuit concluded that the defendant, who was involved in a conspiracy involving cloned satellite descramblers for unauthorized interception of satellite programming, was properly charged under § 2512. While admitting that there was some legislative history to the contrary, the Tenth Circuit determined that it was ambiguous and looked to the plain language of the statute for guidance. Under the statute, “intercept” is defined as “the aural or other acquisition of the contents of any wire, electronic, or oral communication through the use of any electronic, mechanical, or other device.” 18 U.S.C. § 2510(4). “Electronic communication” is defined as “any transfer of signs, signals, writing, images, sounds, data, or intelligence of any nature transmitted in whole or in part by a wire, radio_” 18 U.S.C. § 2510(12).
  The Tenth Circuit reasoned that satellite television transmissions carry both images and sounds by radio waves and that the defendant’s cloned descramblers were electronic devices which intercepted electronic communications. 908 F.2d at 564-65. The reception of programming through the cloned descramblers is surreptitious because the satellite television program providers are unaware that it is being intercepted. Id. at 565. Therefore, the Tenth Circuit concluded that the defendant was properly charged under § 2512. Id. No mention was made of 47 U.S.C. § 605.
  The Eleventh Circuit reached the opposite conclusion in United States v. Herring, 933 F.2d 932 (1991), a case in which the defendants modified VideoCipher II units so that they could receive unauthorized satellite programming. In Herring, the court provided a thorough historical and precedential review of § 2512. In doing so, the court cited United States v. Schweihs, 569 F.2d 965 (5th Cir.1978), a case which reverses a conviction under § 2511(l)(b) as it was originally promulgated. In Schweihs, the defendant had made an amplifier that aided him in avoiding an alarm system in an office he was burglarizing. The Government witnesses testified that the amplifier could be used with ordinary audio equipment and that it was not primarily useful for surreptitious listening. Id. at 969. In overturning the conviction, the court in Schweihs examined the legislative history and concluded that even a device that was constructed for eavesdropping was not prohibited by the statute “if its design characteristics do not render it primarily useful for that purpose.” Id. at 968. The court stated that the statutory language “reflects a careful and studied congressional decision to leave untouched the production, distribution, and possession of electronic equipment designed for regular use in varied nonsurrep-titious activities, even though the equipment is capable of being used in a surreptitious manner_” Id. The Eleventh Circuit determined that the modified de-scramblers in Herring also had no specifically surreptitious characteristics. Herring at 934. Their similarity to legitimate descramblers was precisely what made them useful for illegitimate reception of satellite transmissions. Id. Because the descramblers have significant legitimate uses and are not primarily useful for surreptitious listening, the Eleventh Circuit concluded that the Herring defendants could not have been convicted under § 2512(l)(b) prior to its amendment. Id.
  The legislative history of the 1986 amendments to the Wiretap Law stated that private viewing of cable programming was governed exclusively by 47 U.S.C. § 605. The Eleventh Circuit noted that the provisions of § 605 clearly prohibited the defendants’ conduct in modifying de-scramblers to allow unauthorized access to satellite programming. Herring at 937. In examining whether both 47 U.S.C. § 605 and 18 U.S.C. § 2512(l)(b) applied to the conduct, the court noted that criminal statutes are to be construed narrowly in favor of the defendant. Rewis v. United States, 401 U.S. 808, 812, 91 S.Ct. 1056, 1059, 28 L.Ed.2d 493 (1971). The court concluded that the ambiguity of the statute and its history, in conjunction with the fact that the conduct would not have been prohibited under the Fifth Circuit’s interpretation of § 2512(l)(b) in Schweihs, indicated that lenity was appropriate. Herring at 937. Next, the court noted the principle of statutory construction that a “statute dealing with a narrow, precise, and specific subject is not submerged by a later enacted statute covering a more generalized spectrum.” Id. (citing Radzanower v. Touche Ross & Co., 426 U.S. 148, 153, 96 S.Ct. 1989, 1992, 48 L.Ed.2d 540 (1976)). The Eleventh Circuit acknowledged that where statutes overlap, the prosecutor has discretion in choosing the statute for indictment. Id. at 938. However, the court concluded that these statutes do not overlap, or even if they do, § 2512(l)(b) is so ambiguous as to require prosecution under the more specific statute. Id. at 938.
  Finally, the Eleventh Circuit acknowledged the Tenth Circuit’s position in McNutt, supra. The court determined that McNutt incorrectly interpreted “surreptitiously” for the purpose of § 2512(l)(b). Id. at 938-39. Citing Schweihs, the court concluded that the significant legitimate uses for the descramblers take them out of the ambit of the devices prohibited under § 2512(l)(b).
  C. Conclusion
  The difference of opinion in the Circuits demonstrates that the interpretation of § 2512(l)(b) is a difficult matter. Under the Tenth Circuit’s interpretation, Hux’s conduct was prohibited by § 2512(l)(b). However, that interpretation discounts the legislative history and ignores the existence of 47 U.S.C. § 605. We believe that the Eleventh Circuit has the better reasoned approach in considering the past and present legislative history, prior case law, principles of statutory construction, and the provisions of 47 U.S.C. § 605. Accordingly, we reverse Hux’s conviction under 18 U.S.C. § 2512(l)(b).
  III. ADMISSIBILITY OF EVIDENCE
  Next, Hux complains that the district court erred in admitting General Instruments’ copyright certificates because they did not appear on the Government’s evidence list and were not produced by the Government until the first day of trial. Hux notes that Federal Rule of Criminal Procedure 12(d) requires the Government to provide notice of its intention to use in its case-in-chief any evidence that the defendant is entitled to discover under Federal Rule of Criminal Procedure 16. Hux submits that this untimely production of evidence prejudiced his ability to prepare for trial.
  At trial, the defense objected to the admission of the certificates. Upon the objection, the trial court held a bench conference. The Government attorney stated that he had just received the certificates on the morning of the trial. The Government noted that the certificates were merely business documents showing registration of the copyrights, not the copyrighted programs themselves. The trial judge extended the lunch recess so that defense counsel would have an adequate opportunity to examine the documents and then ruled that the certificates were admissible.
  This court may reverse the district court’s evidentiary rulings only upon a showing of an abuse of discretion. United States v. Simon, 767 F.2d 420 (8th Cir.), cert. denied, 474 U.S. 863, 106 S.Ct. 179, 88 L.Ed.2d 148 (1985). We conclude that there has been no such abuse in this case. As the Government noted, the certificates were merely business documents that substantiated the existence of the copyrights. Hux presented an expert witness who testified about the actual copyrighted material and concluded that there had been no infringement. Thus the tardy production of the certificates did not preclude Hux from preparing his defense with regard to the copyrighted material. Additionally the judge allowed the defense counsel adequate time to examine the documents during the long lunch break. Defense counsel did not indicate that he needed more time. Accordingly, we conclude that the district court did not abuse its discretion in admitting the certificates.
  IV. SUFFICIENCY OF THE EVIDENCE
  Hux was indicted under 17 U.S.C. § 506(a) which applies to “[a]ny person who infringes a copyright willfully and for purposes of commercial advantage or private financial gain....” The district court instructed the jury that the Government must prove the following elements beyond a reasonable doubt: 1) that the computer program in the satellite descrambler modules had a valid copyright; 2) that Hux infringed the copyright by preparing one or more derivative works or computer programs, or by reproducing or selling unauthorized copies of the computer program; 3) that Hux willfully infringed the copyright; and 4) that the act of infringement was for commercial advantage or private financial gain.
  Hux argues that the evidence was insufficient to sustain his convictions under § 506(a). Hux notes that only 205 bytes on the computer chip he developed were similar to the total of 16,384 bytes on General Instruments’ chip. He contends that this similarity is insignificant and that he merely replaced the original chip with another that was the product of his own labor. As such, he argues that there has been no copyright infringement. Apple Computer, Inc. v. Formula International, Inc., 562 F.Supp. 775, 782 (C.D.Cal.1983), aff'd, 725 F.2d 521 (9th Cir.1984) (one may make a machine do the same thing it would if the copyrighted material were placed in it as long as it is by one’s own creative effort, not piracy). Hux also disputes that the Government proved the second element of infringement. Hux’s expert witness testified that Hux’s chip was not a derivative work or other infringement of the General Instruments’ chip.
  In reviewing the sufficiency of the evidence, a conviction must be upheld, if viewing the evidence in the light most favorable to the Government, substantial evidence supports the jury’s verdict. United States v. Marin-Cifuentes, 866 F.2d 988, 992 (8th Cir.1989), cert. denied, — U.S. -, 110 S.Ct. 110, 107 L.Ed.2d 72 (1989). The Government is also entitled to all reasonable inferences drawn from the evidence. Id. Additionally, the evidence need not exclude every reasonable hypothesis except guilt. It must only be sufficient to convince the jury of the defendant’s guilt beyond a reasonable doubt. Id.
  In addition to the copyright certificates, two witnesses testified that General Instruments held valid copyrights for the computer program in the descramblers Hux modified. A Government witness testified that the computer chips Hux substituted were derivative and essentially the same as General Instruments’ copyrighted chip. An FBI agent assigned to the investigation testified that Hux admitted knowing that what he was doing was illegal. The purchaser of the modified units testified that he paid Hux $400 for each modification. Thus, evidence was presented on each of the four elements. Viewing this evidence in the light most favorable to the Government, we conclude that it was sufficient for the jury to reasonably find Hux guilty beyond a reasonable doubt of copyright infringement. Accordingly, we affirm the conviction.

  . 18 U.S.C. § 2511(4)(c) provides:
  Conduct otherwise an offense under this subsection that consists of or relates to the interception of a satellite transmission that is not encrypted or scrambled and that is transmitted—
  (i) to a broadcasting station for the purposes of retransmission to the general public; or
  (ii) as an audio subcarrier intended for redistribution to facilities open to the public, but not including data transmission or telephone calls,
  is not an offense under this subsection unless the conduct is for the purposes of direct or indirect commercial advantage or private financial gain.
  18 U.S.C. § 2511(5)(a)(i)(A) subjects private viewing of unencrypted satellite transmissions to a suit by the Government.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "manufacturing". Your task is to determine what subcategory of business best describes this litigant.
