KW - 9 Maurice Cammack recalls his experiences with the KW-9. "We communicated securely with KW-9's using AN/GRC-46 RTTY vans, homemade MSC-29s (using TT-76s, TT-4s, TCC-14's all mounted on wooden benches and racks) and in the Base CommCen at Camp Page. We also had two homemade rigs, mounted on 3/4 ton trucks for NAICP response communications.

Without exception, we were lucky to get 3 or 4 messages out before losing sync and having to reconnect. The 8th Army support element for our crypto was run by CWO Freshwater. Mr. Freshwater issued us extra baskets and rotors when we were in the field. I put one guy on, full-time, just cleaning, and setting up spare baskets so that we could swap out anytime that sync was lost.

These CE91798 diodes were part of the TSEC/KW-9 translators. Mounted on the bottom of the KW-9 rotor stepping unit, there were two translator blocks with hexagonal shaped holes (like honey combs) filled with dozens of these diodes. (Photo and copy courtesy George Mace)
