Asked to call xxxx center for possible pilot deviation.hand off from 1 freq to the next didnt go well .recollecting my thoughts i believe what happened was i inadvertently deselect the audio and was distracted around the time of the freq changE which apparently i did acknowledge. When i realized what happened i scrambled to get the comms back,i moved my hand towards the control head on the vhf and thought "volume" i turned the knob and i actually changed the freq not volume now i had lost the freq and the previous one was 2 far away.fortunately the freq i dialed in was an active freq and i was able to regain comms ( 17 minutes off comms according to the supervisor,we called from the aircraft) we both filed a NASA
He said he had to send the report to the next level.
Is 17 minutes an awful long time? This is not the same as 1 hour.
