[MRCA] In Search of TCZ Technical Documentation

[Christopher Bowne]

Good morning and Happy New Year.  I’ve recently been recruited by Ken Carr, one of the Board of Directors at the New England Wireless and Steam Museum in East Greenwich RI, to assist the volunteers of the radio side gang in restoring to operating conditon a Navy TCZ transmitter, the shipboard variant of the ART-13.  The museum apparently has at least one ART-13 and several of the TCZ motor generator/rectifier power supplies that the transmitter sits on top of in the shipboard configuration.  Either a link to an online tech manual or a source of a hard copy would be a good start.  Brown, I recall you may have had (and perhaps still do have) a TCZ at Fort Burnside.  If I recall correctly, the power supply consists of an AC powered motoe  generator vice a dynamotor to generate the 400V and 1100V DC required for low and high B plus, and a transformer and rectifiers to make the 28 VDC for the tube filaments, relay control, and auto tune motor power.  At any rate it looks like a fun project and it would be great to have an ART-13 on the air from the museum.

Maybe we might some day be able to rig it up to a steam powered AC generator set and have a real steampunk station on the air from there during Steam Up.
