Category II Testing on the Philco HF and Wireline Data Modems and Test Set

摘要

The document describes Category II field testing of AN/USC-12 HF radio modem equipment, AN/GSC-20 wire-line modem equipment and the AN/USM-235 digital test set. Most of this testing was done during November and December 1966 between Cape Kennedy AFS and the Antigua, W.I. range station; however, a few interface tests were done at a later date subject to the availability of certain test facilities. The results of this test program are included with appropriate comments. (Author)
