Do raspberries like full sun? Or do they perhaps prefer partial shade?
I have a red variety but I don't remember what it is exactly. Out in
the sun they look a bit stressed. I have some thornless blackberries
in partial shade and they don't seem to like it. I would swap them but
the sunny area is fenced and thus better for isolating something with
I think partial shade works best for them. I had a few raspberry bushes in a
full sun spot and they were literally fighting for survival for three years
until I moved them into the shade created by picket fence (and a medium size
tree for a part of the day). They seem quite happy there, no yellowing and
blooming rather well this year. It would be the first year in partial shade, so
I'm not sure if less sun affects the taste of the berries, but at least the
plants themselves look much healthier there.
That part of the garden is further away from the house, so the soil is not
damaged by all the construction activity 6 years ago. So, perhaps there are
several factors at play here, not just the amount of sun.
I suspect that is the case. I don't have direct experience of raspberries
(my soil is too heavy) but I have found that fruiting plants do require full
sun, the more sun they get the more energy they have to make sugar for the
Yellowing sounds more like a nutrient issue to me.
They are a crop that naturally (in the wild) goes for burned over land -
However if you are more equatorial (I'm around 42 degrees, so not
equatorial at all) you may have a different issue with what "full sun"
means for you, and what that does to crops which want full sun here. I
don't mean full on tropical, just significantly closer to the equator,
and thus getting more of a strong overhead sun.
They will _grow_ in partial shade, but not fruit as much as in full sun
They also need to be thinned rather ruthlessly for continued production
- either the simple brute force method of mow half the patch flat in
alternating years, or cutting all the old canes and thinning the new
ones to a pretty wide spacing.

Please don't feed the trolls. Killfile and ignore them so they will go away.
I have messed with various blackberries but raspberries seem to be a
little different. I'm at 38.5N and the summer heat out in the full sun
can be brutal. Since raspberries seem to have shallow roots I am going
to need to keep them mulched and watered. These had been growing wild
in a nearby wooded area for many years. I moved them last spring. I
think they are descendants of some raspberries I grew briefly many
years ago. Last year after the heat wave the canes started growing in
a leggy ground hugging fashion. So far this year the new canes are
growing erect, like a normal, healthy blackberry would.
