Appellant contends that (1) his speedy trial rights were violated, (2) the trial judge made numerous errors, and (3) his trial counsel was ineffective. We find these contentions meritless and, accordingly, affirm.
On February 26, 1980, appellant was arrested on charges of rape, involuntary deviate sexual intercourse, indecent assault and corruption of a minor. He was arraigned on March 3, 1980, and a preliminary hearing was scheduled for ten days later. On March 13, 1980, a snowstorm closed the district court, and the preliminary hearing was rescheduled for March 21, 1980. On that date, appellant failed to appear. He was arrested in Wyoming two and one-half months later and returned to the Commonwealth on June 5, 1980. His preliminary hearing was held on June 11, 1980 and continued to June 18. Following an October 20-23, 1980 jury trial, appellant was found guilty of all charges except the rape charge. Post-verdict motions were denied on May 18, 1982, and on July 20, appellant was sentenced to a term of imprisonment of eight-to-twenty years. This appeal followed.
Appellant first contends that he .was denied a speedy disposition of the charges filed against him. He alleges that his preliminary hearing was not .timely and that he did not receive notice of it. Pa.R.Crim.P. 140(d) provides that a preliminary hearing shall be scheduled “not less than three nor more than ten days after preliminary arraignment unless extended for good cause shown,” and that the defendant shall have notice of the time arid place- of the hearing. Here, we find that the snowstorm was good cause for rescheduling the preliminary hearing for March 21, *402 1980, beyond the ten day limitation. We also find appellant’s claim that he was not given notice of the hearing to be without merit. Detective Raymond Bechtel testified that, on March 13, 1980, the district judge advised appellant by phone of the date and time of the rescheduled hearing. (N.T., Rule 1100 Hearing, October 20, 1980 at 25).
Appellant also argues that his right to a speedy trial under Pa.R.Crim.P. 1100 was violated. Rule 1100(a)(2) provides that trial in a court case must commence within 180 days from the date on which the criminal complaint is filed. In making that computation, however, any periods of time in which the defendant was unavailable are excluded. Pa.R.Crim.P. 1100(d)(3)(i). Here, we find that appellant was unavailable from the time he failed to appear for the March 21, 1980 hearing until his June 5, extradition from Wyoming, a period of seventy-six days. Excluding that period, the Rule 1100 run date is extended to November 4, 1980, 256 days from the date the complaint was filed. Because the trial commenced on October 20, 1980, we hold that Rule 1100 was not violated. 1
Appellant next contends that the eleven month delay between the argument of his post-verdict motions and the order denying them was excessive. Pa.R.Crim.P. 1122 provides that post-verdict motions must be decided within thirty days after argument, “except under unusual circumstances.” Here, appellant’s post-verdict motions were argued on May 18, 1981. Because of the nature of these motions, two evidentiary hearings were held on July 14, 1981 and May 13, 1982. The delay in holding the second hearing was occasioned by the unavailability of a necessary witness who was in the Navy. The trial court then decided the motions five days after the second hearing. Under these circumstances, we hold that the delay was not improper.
*403
Appellant also complains of the two month delay before his sentencing and the lapse of thirteen months between the filing of his notice of appeal and the issuance of the lower court’s opinion. While unreasonable delay by the courts is not to be encouraged, the constitutional and statutory rules guaranteeing speedy trials do not apply to post-trial proceedings, particularly in the absence of a showing of prejudice.
Commonwealth v. Hill,
267 Pa.Superior Ct. 264, 268,
Appellant next claims that remarks made by a Commonwealth witness raised an inference of previous criminal conduct on appellant’s part sufficient to warrant a mistrial. In response to cross-examination by defense counsel, the witness testified that she had known appellant “since he came home from jail.” (N.T. October 20-23, 1980 at 79). Ordinarily, admission of testimony which describes, or from which the jury may infer, past criminal conduct by a defendant constitutes reversible error.
Commonwealth v. Nichols,
Appellant also argues that he is entitled to a new trial because the jury foreman took notes when the trial court, upon jury request, repeated the elements of the crimes charged. Under Pennsylvania law, it is improper for a juror to take notes during a trial and to use those notes in the jury room. Pa.R.Crim.P. 1113;
Commonwealth v. Pierce,
Appellant next contends that it was error for the trial court to refuse to instruct the jury with the maxim “falsus in uno, falsus in omnibus,”
i.e.,
if a witness willfully and corruptly swears falsely to any material fact in a case, the jury may disregard all of that witness’ testimony.
See Commonwealth v. Parente,
184 Pa.Superior Ct. 125, 131,
Appellant’s next argument is that the trial court erroneously refused to grant a continuance in the middle of the trial. Appellant claims that a continuance was necessary to serve a bench warrant on a missing witness. “The denial of a continuance by the trial judge constitutes revers
*406
ible error only if there has been an abuse of discretion.”
Commonwealth v. Howard,
Appellant next contends that the Commonwealth’s evidence was so contradictory that it could not form the basis for a guilty verdict. Where evidence offered to support a verdict of guilty is so unreliable or contradictory as to make any verdict based thereon pure conjecture, a jury may not be permitted to return such a finding.
Commonwealth v. Farquharson,
Appellant also claims that the verdicts were inconsistent, thus warranting an arrest of judgment. He argues that his acquittal on the rape charge was inconsistent with his conviction on the charge of involuntary deviate sexual intercourse. Consistency in criminal verdicts is not necessary, and logical inconsistencies will not serve as grounds for reversal.
Commonwealth v. Williams,
294 Pa.Superior Ct. 93, 97-98,
Appellant’s next contention is that the trial court erred in relying upon sentencing guidelines which were not then in effect. During sentencing, the trial court stated that, although the new guidelines were not due to become effective for two days, he had found them useful. (N.T. July 20, 1982 at 9).
The imposition of sentence is a matter vested in the sound discretion of the sentencing judge, whose determination will not be disturbed on appeal absent a manifest abuse of discretion. If the sentence is within statutory limits there is no abuse of discretion unless the sentence is so manifestly excessive as to inflict too severe a punishment.
Commonwealth v. Russell,
313 Pa.Superior Ct. 534, 545,
Appellant’s next argument is that the statutory prohibition against involuntary deviate sexual intercourse is an unconstitutional denial of equal protection.
5
As a general rule, issues not raised in the lower court are waived and cannot be raised for the first time on appeal. Pa.R.A.P. 302(a). Waiver may not be avoided by alleging that the issue is of constitutional dimension.
Commonwealth ex rel. Bulson v. Bulson,
278 Pa.Superior Ct. 6, 8-9,
Appellant further contends, however, that his trial counsel was ineffective for failing to raise the unconstitutionality of the prohibition against involuntary deviate sexual intercourse. When confronted with a claim of ineffectiveness, we must first determine whether the issues underlying the claim are of arguable merit. If the underlying issues are found to have arguable merit, then we determine whether the strategy chosen by trial counsel had some reasonable basis designed to effectuate the client’s interests.
Commonwealth v. Evans,
Appellant bases his constitutional claim upon the successful equal protection argument made in
Commonwealth v. Bonadio,
Appellant also contends that counsel was ineffective for advising him not to testify at trial. “The choice of whether to testify rests on the accused, it being counsel’s function to advise fully of the consequences.”
Commonwealth v. Lincoln,
270 Pa.Superior Ct. 489, 494,
Appellant’s last contention is that counsel was ineffective for failing to call certain witnesses. Trial counsel need not call to the witness stand every witness mentioned by a defendant when counsel has a reasonable basis to believe that such witness would not be helpful to the client’s defense.
Commonwealth v. Banks,
267 Pa.Superior Ct. 10, 13,
For the foregoing reasons, we affirm the judgment of sentence.
Affirmed.
Notes
. Before appellant was brought to trial, the Commonwealth petitioned for Rule 1100 extensions on two occasions. Because we have found that appellant’s trial was timely, even without those extensions, we need not address whether those petitions were properly granted.
. Appellant also asserts that a mistrial was warranted by the fact that a juror may have seen him in handcuffs. Ordinarily, we will not consider any issue which is not set forth in the statement of questions section of the appellate brief. Pa.R.A.P. 2116;
Kerr v. O'Donovan,
. Appellant also fails to point to any testimony which would warrant the instruction under this standard.
. Appellant also claims that the trial court failed to place on the record the relevant factors in imposing sentence. In light of appellant’s concession in his appellate brief that the trial court did place its reasons for imposing the sentence in the record, we find this claim patently frivolous. See Brief for Appellant at 34.
. 18 Pa.C.S.A. § 3123 defines involuntary deviate sexual intercourse' as follows:
A person commits a felony of the first degree when he engages in deviate sexual intercourse with another person:
(1) by forcible compulsion;
(2) by threat of forcible compulsion that would prevent resistance by a person of reasonable resolution;
(3) who is unconscious;
(4) who is so mentally deranged that such a person is incapable of consent; or
(5) who is less than 16 years of age.
. 18 Pa.C.S.A. § 3124 defines voluntary deviate sexual intercourse as follows:
A person who engages in deviate sexual intercourse under circumstances not covered by section 3123 of this title (related to involuntary deviate sexual intercourse) is guilty of a misdemeanor of the second degree.
. 18 Pa.C.S.A. § 3101 defines deviate sexual intercourse as follows:
Sexual intercourse per os or per anus between human beings who are not husband and wife, and any form of sexual intercourse with an animal.
. Except where an invidious discrimination against a suspected class is at issue or a fundamental right is burdened, "a legislative classification must be sustained unless it is ‘patently arbitrary’ and bears no rational relationship to a legitimate governmental interest.”
Singer v. Sheppard,
. Appellant specifically alleges that the testimony of Gerald Moore, whom trial counsel was unable to locate, would have contradicted that of the Commonwealth’s witnesses. However, Moore’s testimony at the second evidentiary hearing on the post-verdict motions only contradicted that of Commonwealth witnesses on collateral matters. Because "[e]xtrinsic evidence is improperly admitted in rebuttal if it is relevant only to a collateral matter,”
