And so a fair number of RB channel repeaters have moved to wide split
7.6MHz channels to avoid this.

No that's a myth - more like the repeater keepers can't be arsed to
put in the effort to get a duplexer working properly with +1.6MHz
split.

I know this to be true fairly locally, the reason being crane jib transponders very close to the repeater input and already affecting
another local repeater.
In any case a lot of these repeaters have been operating on 1.6MHz
split for a long old time.

Never mind crane jib transponders, what happens if my door bell isn't
working and I miss my Amazon parcel?

They'll just dump it on the doormat without ringing the bell, as
happened to me earlier today. It's entirely random as to whether you
get a driver that waits or that is off like a scalded cat.

A good question. This is one reason why the repeaters have moved
frequency, to avoid likely legal cases. In the past repeaters have
been forced to close down due to interference from a perfectly legal
amateur secondary user affecting unprotected systems (car remote locking devices) so the problem is that as usual the authorities can't follow
their own rules which say that unprotected means exactly that. It's not unprotected when people get locked out of their cars, because they said
so.
Yes, inveterate cynic alert.

What exactly are those transponders for?

I believe that they measure both wind speed and jib flex in use, if
either exceed preset limits then the crane operator gets a warning that
the crane must cease operation until both limits are no longer exceeded.

I think they are mostly used for anti-collision in areas where there
is more than one crane so as to stop any conflict between the booms.

I wonder if they can be decoded by rtl_433? Most useful thing I've done
with that software is monitor the TPM on the car because the tyre
pressure warning never tells me which one is low.

There is an adequate gap in the tyre wall where it fits on the wheel. The only
other requirement is that lithium cells generally last longer then tyres.
