The only niggle, you had to scan through stations to find the one you
wanted,

And that was the rub and what I was trying to avoid with 'set' tuning
jobby.

although I think I remained tuned to the last one used when turned
off and back on.

Well that would be ok, as long as it didn't also autotune, if it lost
signal for a second (as I think the one I had did).

Perhaps I wasn’t clear.

No, I think you were.

It had an ‘auto tune’ which worked surprisingly well. When you used it the
first time, you pressed a button and it scanned for the first station and
stopped.

Yup.

If that was the one you wanted, fine. If not you pressed the
button again and it scanned for the next one and so on.

Yup, like my Yupiteru MVT-7100 scanner or my car radio come to that.

The pain was you
needed to cycle through a ‘list’ and there wasn’t a display.

Yup ...

However, as I
recall, it stored the last station listened to.

Yup ... and I said as long as that was the case, it wouldn't be a
dealbreaker. ;-)

When I typed the first post we were on the A1, XYL was driving. I’m now
home and have looked where I thought the radios where (well one of the
places). I’ll keep looking and, if I find one, see if there is a part
number on the IC.

Thanks.

The problem will be if it turns out it re-scans (on it's own) if it
loses sufficient signal strength to stay locked on (which is what I
said I think the one I had did).

I assume all that sort of thing would be built into the IC itself as
from what I've seen, they just have up / down (or just up) scan
buttons but not much else that might influence the start of a re-scan,
if the signal was lost (other than that's inside the IC etc).

If it still relied on an external tuning capacitor then we could still
be in business. ;-)
