          I own one RACAL-DANA 1992 (Standard- TCXO).  I purchased one with the Option 04E on eBAY.

          The 04E chassis is sealed and the internal OCXO overheats due to lack of cooling air.  This causes the counter to stop taking measurements.  I had to add ventilation holes on the top and right side of the chassis lid to obtain reliable operation.

          Both counters work up to 1,750 MHz.
