Hi PJH,
I was the newbie with the question, Marc and others kindly answered. I'd put the thing on the wrong way round and could not see the holes as they were hidden under the LCD display. I think you mixed us up :-)
Now looks like I got the T1 toroid wrong, will check it out tomorrow... can't receive anything but extremely strong signals. Think I'll have to rewind it all over, when I can find the right wire. Otherwise all seems good.
