Then came the Collins and PTR175
I was amused to see a Collins being retuned in the video from what appeared to be the BBC World Service. That gives some inkling of the gravity of the situation. It was a mainstay of the prolonged over-the-og transits in the Hercules. On the Hastings the sigs desk had a drawer in which he kept his segmented allotted crystals for the route. They enabled him to pass you the New York weather rather than Christmas Island's to which you were inbound.
The variable nature of HF radio Rx is well known and could be used to some advantage of course, "Unless advised to the contrary, intend to bypass A and proceed direct B", knowing that the propagation conditions gave you a good chance of a better nightstop at B.
