Can’t find a specific model number probably due to this being an modular assembly part of a CEI receiver system. I’ve been using it with a Watkins-Johnson / CEI VHF receiver which I also have listed for sale. Will consider offers for both the receiver and monitor scope in a combined sale. Unit functions perfectly with sharp / bright display on the 3ASP1 CRT.

Specifications:

IF / Input Frequency: 21.4 MHz
Sweep Width: 0 to 3 MHz
Sweep Rate: 5 to 25 Hz

Center Frequency Marker at 21.4 MHz

Pick-up in London preferred, however can ship at cost via Canada Post.
