Narrative:

On climb out of phl second officer gets my attention with the largest split (left/right) in duct pressure I've ever seen. Helpful first officer dials in sby-114.5, which I recognized, but had no time to identify. ATC asked if we were going to sby. We discovered first officer did do his revision, but discarded the wrong chart! Egads! We were going to brooke, which is now 114.5. Also, when salisbury, which is now 111.2 is selected, the omega navigation system disconnects! If a VOR frequency is changed, it should be relocated at least 400 mi away. No arwy VOR should have a low frequency band which trips the omega system.

Narrative: ON CLBOUT OF PHL S/O GETS MY ATTN WITH THE LARGEST SPLIT (L/R) IN DUCT PRESSURE I'VE EVER SEEN. HELPFUL F/O DIALS IN SBY-114.5, WHICH I RECOGNIZED, BUT HAD NO TIME TO IDENTIFY. ATC ASKED IF WE WERE GOING TO SBY. WE DISCOVERED F/O DID DO HIS REVISION, BUT DISCARDED THE WRONG CHART! EGADS! WE WERE GOING TO BROOKE, WHICH IS NOW 114.5. ALSO, WHEN SALISBURY, WHICH IS NOW 111.2 IS SELECTED, THE OMEGA NAV SYSTEM DISCONNECTS! IF A VOR FREQ IS CHANGED, IT SHOULD BE RELOCATED AT LEAST 400 MI AWAY. NO ARWY VOR SHOULD HAVE A LOW FREQ BAND WHICH TRIPS THE OMEGA SYS.
