Please explain the causal connection which permits me to update that making radio transmitters decreases the chance of nuclear war.
It changes the map, not the territory. It may or may not update your own assigned probabilities, based on your own priors and accepted belief structures. But the actual chance of nuclear war is the same before and after.
They are not analagous. In the smoking lesion problem the lesion causes a desire to smoke, and therefore wanting to smoke is evidence for updating your probability of getting cancer, which the smoking lesion also causes.
In this case there is no causal connection between building radio transmitters or self-replicating machines and mitigation of causal risks that are likely to underlie the great filter, so no you don’t get to update.
Probability is in both the mind and the universe, and neither approach is very useful in isolation. What is the objective of the OP?
To reduce perceived existential risk, build radio transmitters. This has negligible effect on the actual risk of a great filter event.
To reduce actual existential risk, work on nuclear disarmament, asteroid detection, permanent space settlement, friendly AI, etc.
Let me put it this way: of the possible great filter scenarios, how many causally depend to any significant degree on the construction of radio transmitters? I can think of a few weird outlandish, Hollywood inspired possibilities (e.g. aliens that purposefully hide all their activity from our sight, yet are nearby and wait for the signal to come destroy us. positive outcomes are also imaginable, though equally unlikely). Since the probability of such cases are approximately zero, when successfully build a radio transmitter, it tells us approximately nothing. We already know the outcome, so we might as well update on it now.
Then again, once we built the radio transmitter all those same threats of nuclear war, asteroid impacts, and UFAI still exist. We haven’t lessened the actual chance of humanity wiping itself out. You may build your radio transmitter, only to have it destroyed or powered off five years later in the next nuclear war, cometary impact, or by an UFAI that doesn’t see its merit.
In my LW post Quickly passing through the great filter I advocated flooding the galaxy with radio signals to prove we have escaped the great filter.
Which doesn’t prove anything. Does making a radio transmitter make the chance of nuclear war less likely?
Yes, if you accepted that the Fermi paradox and great filter argument means we are probably doomed.

It might not be causal, but you can still update as you can in the smoking lesion problem.

Seems like James is using “probability is in the mind” and you are using “probability is in the universe.” Please correct me if I’m wrong.
