Operation crossbow mission

[Shibbyland]

Trying to fly the Crossbow mission. I get correct tuning to Eastchurch and fly to it as waypoint 1 but a couple of things happen. My visual DF indications will track normally but on passing overhead Eastchurch they continue to indicate on track rather than collapsing as I pass overhead.

I'm unable to tune to any other DR channel successfully.

What am I missing

The D/R needles will not collapse unless the signal beacon at the airfields is turned off. During the mission there are image instructions that appear on screen (both left and right centre)advising you of the next D/R channel to tune to; in this case Hawkinge on 7.71 mc. The images remain on screen for 25 seconds which should give ample time to read them. Once tuned from the navigator seat, the needles will switch and fly you toward Hawkinge. The process is repeated throughout the mission, for navigational changes. I tetsed the mission this morning and found no issues. I hope this helps. Cheers.
