Slightly off-topic but I've noticed that the LBA VHF tower frequency is now on 'simul-cast' with the UHF ground frequency. It's not a true band-box in the strict sense as stations on VHF cannot hear stations on UHF and vice versa, i.e. there's no retransmission. Hope that makes sense.
Traditionally at LBA the VCR Assistant has manned the UHF frequency under the VCR Controller's licence, obviously allowing the controller to come in on the frequency whenever necessary or convenient. Now the controller is manning this frequency exclusively.
I guess this alteration is just temporary and has something to do with the forthcoming switch upgrade. I'm sure anyone in the know will say if I'm barking up the wrong tree.
