After reading this thread I'm curious about aerial earthing. For an aerial to be effective, it needs an earth. It's generally agreed that the chassis should be earthed through 3 core flex. As noted above, earthing the chassis will usually provide the earth for the aerial however it can also reduce sensitivity and or increase interference. Would a separate radio earth in addition to the chassis mains earth improve reception and decrease interference?

Would a separate radio earth in addition to the chassis mains earth improve reception and decrease interference? Theoretically, yes. The mains earth can carry RFI from noisy devices and can float some volts above zero. A decent earth stake should avoid both of those problems and may improve long distance reception with a long wire antenna. However, as mentioned above, providing such an earth to a set may require re-trimimng the tuning cap. And, of course, don't ever earth a "hot chassis" set!
