Rоbert Grego and Joseph Astling were convicted of violation of 21 U.S.C. § 846 (1981), conspiring to possess and distribute marijuana. Astling was also convicted of two counts of using the teleрhone to facilitate the alleged conspiracy in violation of 21 U.S.C. § 843(b) (1981). Both argue on appeal that: (1) a taped conversation with a government informant should have been suppressed because they were at the time under indictment in Georgia, (2) a radio transmitter seized during a warrantless search of the truck should have beеn excluded from evidence, (3) motions of acquittal should have been sustained because there was no evidence of conspiracy, and (4) the tape should have been suppressed because it was inaudible. We affirm the judgment of the district court. 1
The government’s case was based on a conversation that occurred in Little Rock, Arkansas, between Grego and Astling and an experienced government informant, Benjamin Rothwell. The conversations were recorded by a body mike worn by Rothwell and transmitted to a nearby drug enforcement administration vehicle. After the three left the dining room in a motel where the conversation occurred, Grego and Astling were аrrested as they started a truck to drive away. Before this conversation on April 30, 1982, Astling and Grego had been indicted by a federal grand jury in Georgia on April 22, 1982, on charges of сonspiring to import marijuana into the United States.
I.
Astling and Grego argue that their sixth amendment right to counsel was violated by the taping of the conversation concerning importing. marijuana into Arkansas which occurred just eight days after the return of an indictment on similar charges in Georgia. They rely on
Massiah
v.
United States,
The exclusionary rule of Massiah is not applicable in this case. In Massiah the government sought to use the defendant’s incriminating post-indictment state- *703 merits to prove the charge in the pending indiсtment. Here, although Astling and Grego were under indictment in Georgia for importation of marijuana at the time the conversation was taped, the trial in which the tape wаs used was not for that offense. The taped conversation was received in proof of a different offense — conspiracy to possess marijuana with intent tо distribute — committed after the Georgia indictment and before Astling and Grego had been indicted in Arkansas.
It is clear under
Massiah
that the taped conversation could not have been used in defendants’ Georgia trial, but
Massiah
offers no immunity from liability for uncoun-seled, post-indictment statements that involve different criminal acts. Such statements, even though deliberately elicited by government agents after indictment and in the absence of counsel, may form the basis for a separate indictment and may be offered to prove such additional charges.
Hoffa v. United States,
Astling and Grego contend, however, that the taped conversation should be excluded under
Massiah
because the Arkansas crimes were part of a continuing transaction with the earlier crimes for which they were under indictment in Georgia when the recording was made. The two indictments involved different offenses. The Georgia indictmеnt was for importation of marijuana into the United States between January, 1982, and February 9,1982.

The Arkansas indictment was for conspiracy to possess marijuana between February 1, 1982, and April 30, 1982. Although both indictments involve marijuana, the acts on which they were based were separate and distinct and did not amount to a single criminal offense.
Badolato, supra,
When the tape of the conversatiоn was made, Astling and Grego had not been indicted on any offense for which the tape was later used against them; therefore, we affirm the district court’s refusal to apply Massiah to exclude the tape.
II.
Grego and Astling also allege as error the introduction into evidence of a radio transmitter found in Grego’s truck following the arrest. They contend that the transmitter should have been excluded because it was unconstitutionally seized without a warrant. The propriety of the search of the truck is ruled by
South Dakota v. Opperman,
*704 In the instant case the officer testified that he found the radio transmitter while he was conducting a routine inventory search of the truck. The search was conducted in compliаnce with Little Rock Police Department policy. It is plain that the radio transmitter was properly seized in an inventory search authorized by Opperman.
III.
Astling and Grego contend thаt the district court erred in denying their motions for acquittal because the evidence was insufficient to sustain their convictions for conspiracy under 21 U.S.C. § 846.
When an attack is made upon the sufficiency of the evidence, the jury’s verdict must be sustained if there is substantial evidence, viewed in the light most favorable to the government, to support it.
Hamling v. United States,
To be convicted of conspiracy under 21 U.S.C. § 846, the government must prove, by direct or circumstantial evidence, that there was an agreement among the defendants to achieve an illegal purpose.
United States v. Cuni,
Astling also argues that there was not sufficient evidence to support his convictions under 21 U.S.C. § 843(b) for the use of a telephone to further the conspiracy. After a review of the phone conversations of April 29 and 30, as well as the tаped conversation at the motel, we conclude that Astling’s allegations of insufficiency of evidence as to his § 843(b) convictions are also without merit.
IV.
Grego and Astling сlaim that the tape made by the use of the body mike was of such poor quality that it should have been suppressed.
The standard for the admissibility of tape recordings is set fоrth in
United States v. Bell,
In this case the district judge, prior to the trial, listened to the tape. Although a transcript of the tape was read to the jury, only the tape, and not the transcript, was admitted into evidence, and the defendants’ attorneys were offered the opportunity to provide their own transcript for the jury. This procedure is in conformity with Bell, and we do not see an abuse of discretion that would justify reversal.
After a careful review of the defendants’ allegations of error, we are convinced they are without merit and affirm the judgments of the district сourt.
