The PRO-310 is a gorgeous receiver. Unfortunately, it has
a case built inside a case and is very difficult to work
on. On the broadcast band, it is single conversion, which
presents a problem for images.

There were two different color models and they were too
expensive to manufacture. They are certainly collector's
items.

Well, lots of receivers are single conversion on the
broadcast band and do not have image problems. It seems to
me that the PRO-310 did have some problems, something to do
with the gain structure I think. It got fixed but they were
simply too expensive to compete at the time. For about the
same price one could buy a 75A4, which is arguably a better
ham receiver and could buy RX such as the GPR-90 for less
money.
It would be interesting to know the story behind the
PRO-310, it was beautiful, worked well, but just missed the
mark.
