Uher 4000 "Report L" portable audio tape recorder, 1965-66. Portable tape recorder used extensively by BBC radio reporters. Battery: 5 x 1.5 V. Four tape speeds: 15/16, 1 7/8, 3 3/4, 7 1/2 inches per second (ips). Tracks: 2, Maximum reel size: 5''. Many models were modified by the BBC to only operate at 7 1/2 ips, often by removing the speed selector knob and blanking off the hole. Using one recording speed was meant to simplify editing operations. It is not hard to see why the BBC chose this machine; performance and build quality are both excellent. It is solid, reliable, robust, lightweight, and easy to use.
