Abstract
The recent performance history of teh 20-kW S-band transmitter, installed at three 64-meter antennas and six 26-meter antennas in the DSN, is reviewed. An increasing number of failure and Discrepancy Reports are characteristic of teh wearout phase of a failure curve. The type of failures are reviewed and four options toward reducing the number and cost of failures are reviewed. These are existing (no change), refurbish (replace worn components), redesign (extensive improvement) and replacement (with completely new transmitter). The options are compared on a ten-year life cycle cost basis using FY77 expenditures for existing equipment as a base. It is found that benefits, in terms of reductino of outage time, increase with an increase of expenditure toward imrpovement. The choice of optin to be exercised is dependent upon the amount of outage which is acceptable and, or course, upon funds available.
