[OldFuddyDuddy]

Thanks Dave for info about the Rotatone. Although clearly an old fuddy duddy I think it would be impossible to connect with the world without star & hash, so the Rotatone is the one to go for and has the edge on the Sandman. Thanks also for all replies - this is a very helpful forum and particularly encouraging for a newbie.
Of course I may be back on this thread when I attempt to install the internal converter!
