Narrative:
We were given a frequency change by ZNY. The PNF responded, set the new frequency and called the new controller. There was no response and, distracted by other cockpit duties, we neglected to call again. About 20 mins later, I commented that the frequency was very quiet. We attempted to contact ATC and realized that we had tuned in the wrong frequency. Thus, no response on the initial call and subsequent quiet on the frequency. We then contacted ZDC and proper communication was reestablished. We later discovered that while we were without communication with ATC, their radar had failed. Not a good situation! Maybe the fact that we were most of the way through a 13 hour duty day caused our lapse of attention. Stupid mistake on our part in any case!

Title: AN MLG ACR CREW TUNED IN THE WRONG FREQ AND LOST COM FOR 20 MINS.
Narrative: WE WERE GIVEN A FREQ CHANGE BY ZNY. THE PNF RESPONDED, SET THE NEW FREQ AND CALLED THE NEW CTLR. THERE WAS NO RESPONSE AND, DISTRACTED BY OTHER COCKPIT DUTIES, WE NEGLECTED TO CALL AGAIN. ABOUT 20 MINS LATER, I COMMENTED THAT THE FREQ WAS VERY QUIET. WE ATTEMPTED TO CONTACT ATC AND REALIZED THAT WE HAD TUNED IN THE WRONG FREQ. THUS, NO RESPONSE ON THE INITIAL CALL AND SUBSEQUENT QUIET ON THE FREQ. WE THEN CONTACTED ZDC AND PROPER COM WAS REESTABLISHED. WE LATER DISCOVERED THAT WHILE WE WERE WITHOUT COM WITH ATC, THEIR RADAR HAD FAILED. NOT A GOOD SIT! MAYBE THE FACT THAT WE WERE MOST OF THE WAY THROUGH A 13 HR DUTY DAY CAUSED OUR LAPSE OF ATTN. STUPID MISTAKE ON OUR PART IN ANY CASE!
