FINAL KE-6 ELECTRICAL AND MECHANICAL TEST RESULTS
ANALYSIS AND APPRAISAL
One KE-6 was delivered to the R&D Laboratory for final tests.
Previous to this date, the unit had been returned to the manu-
facturer for rework to eliminate several electrical and mechan-
ical deficiencies.
2. ELECTRICAL TEST
The keyer performed during the electrical test as follows:
(a) The voltage applied to the motor input terminals is 5.2
volts, DC.
(b) The keyer operated satisfactorily during the keying test.
All characters were transmitted correctly. The keyer did
not exhibit evidence of incorrect keying when the keyer
buttons were not fully depressed.
The keyer transmits the following International Morse Code letters
when the specified numbered buttons are depressed:

The manufacturer has improved the mechanical features of the
keyer as follows:
(a) A cable clamp has been installed in the keyer to secure
the keyer cable.
(b) The collector ring contact tip has been silver plated.
(c) The individual segment pin contacts beneath each key
button have been raised above the height of the common
contacts. This mechanical improvement eliminates the
possibility of transmitting incorrect characters when
the key is depressed.
The KE-6 Keyer is considered to be a satisfactory device. No
specific recommendations are given.
