Narrative:

Crew had no radio contact between chardon VOR to just east of milton VOR. This occurred because the VOR control on the #1 VHF communication radio was turned down, unknown to crew. I am not sure how it happened, but it involved the type of communication head that has the volume on top of the control head that also includes the frequency selector. I was involved with an engine log reading and also reviewing the STAR into lga. I went over the STAR with my first officer because I had just transferred over to the medium large transport a from the medium large transport B and I had not been in the lga area in over 5 yrs. Upon reviewing the STAR I mentioned that a descent should soon be started to meet a crossing restriction. At that time I mentioned it had been quiet and to check the radios. It was then that we realized the problem. We were able to contact new york center and made a routine arrival to lga. During our time of radio silence we never deviated from altitude or course.

Title: LOST COM FOR ABOUT 200 MI. FOUND VOLUME DOWN, RECONTACT.

Narrative: CREW HAD NO RADIO CONTACT BTWN CHARDON VOR TO JUST E OF MILTON VOR. THIS OCCURRED BECAUSE THE VOR CTL ON THE #1 VHF COM RADIO WAS TURNED DOWN, UNKNOWN TO CREW. I AM NOT SURE HOW IT HAPPENED, BUT IT INVOLVED THE TYPE OF COM HEAD THAT HAS THE VOLUME ON TOP OF THE CTL HEAD THAT ALSO INCLUDES THE FREQ SELECTOR. I WAS INVOLVED WITH AN ENG LOG READING AND ALSO REVIEWING THE STAR INTO LGA. I WENT OVER THE STAR WITH MY FO BECAUSE I HAD JUST TRANSFERRED OVER TO THE MLG A FROM THE MLG B AND I HAD NOT BEEN IN THE LGA AREA IN OVER 5 YRS. UPON REVIEWING THE STAR I MENTIONED THAT A DSCNT SHOULD SOON BE STARTED TO MEET A XING RESTRICTION. AT THAT TIME I MENTIONED IT HAD BEEN QUIET AND TO CHK THE RADIOS. IT WAS THEN THAT WE REALIZED THE PROBLEM. WE WERE ABLE TO CONTACT NEW YORK CENTER AND MADE A ROUTINE ARR TO LGA. DURING OUR TIME OF RADIO SILENCE WE NEVER DEVIATED FROM ALT OR COURSE.
