Group Description

Discussion and help with Cushman CE-3, CE-4, CE-5, CE-6 and CE-7 communication monitors (service monitors). Parts, opinions, manuals and other assistance.

Generally, these CE-series monitors cannot be transmitted into, EVER! (without Model 311 plug-in).

Common pre-discussion problems are the REQUIRED external 20-dB pad for generating from the CE-3/5 (40-dB for CE-6). The CE's are almost useless without aligned M.O., which must be within 4Hz of a calibrated counter. The unit uses many fuses (at least six!) check the many power and signal protection fuses first when a problem occurs. Aside from the hard to find crystal oven (can be rebuilt) and oscilloscope transformer, these monitors are easily repairable.
