My goodness, you’d think that after scheming a significant upgrade like the Mk1 > Mk2 the MoD would at least have Boeing remove all those surplus antennae! VHF Homing. UHF Homing...........
According to the RTS there was no such kit fitted to the Mk2 post-conversion, hence there was no clearance to use it. I do hope the controllers/indicators were removed as well. Confusing to a recent Mk1 pilot you see. All those knobs and switches but no corresponding advice in the RTS/FRCs/ACM. Must have been very confusing. Human factors again.
