1. Project Description:
The CV-24 is a dual channel, IF converter capable of converting
inputs of 500 kHz, 455 kHz, or 100 kHz to either 10 kHz, 15 kHz, or
22 kHz. Separate identical converter channels are provided so that
two receivers may be operated in diversity pairs for reception of
ON/OFF CW signals at 300 WPM. Both headphone and loudspeaker operation
are provided. The following technical characteristics are applicable:
Input impedance - 50 ohms and high impedance for bridging
(each channel)
Output impedance - 600 ohms each channel
Power requirements - 10 watts, 120 volts ?10%, 50/60 Hz,
single phase
Dimensions - 19" rack mounting
Weight - under 10 lbs.

7. Project Status:
Development of the CV-24-dual channel version of the CV-13 IF
converter-has progressed smoothly and remains on schedule. Hum
problems, however, still exist in the audio demodulator section.
This 60 cycle hum has been traced to inadequate filtering in the
power supply and additional filtering should eliminate this problem.
Mechanical and electrical fabrication are 95% completed. Test
specifications,are being written by the contractor for final proto-
type evaluation. Delivery of one prototype is scheduled for
21 October pending completion of the contractor's in-house
evaluation.
