USS INDIANAPOLIS - CA-35  (memorial)

Several Shipboard Transmitters are displayed in the USS Indianapolis Radio room Exhibit.
[]One area contains the, TBS; ART13 & associated Receiver & TDQ.PIX also see RCK info on WWII Recivers page:
[]2nd area has TDE-2,TAJ,TBK & (am)Modulator, TAD & TCK Transmitters. PIX More Below!
[]3rd area has TCS Receiver & Transmitter system. PIX
[]3rd area (Leftside) was Main receiver benchesWWII Recivers page:
[]4th area is the Tech /Work bench area. PIX  &  Exhibit Test Equipment page
Some units received power from Dynamotor sets, others relied on the ships main power sources.
Exhibit volunteers are currently constructing AC power supplies that will enable us to return
the old Transmitters to full service using the similar design antennas..
[]5th area is the Supervisors/Work area and "Radio Shack" Entry door. PIX

    PS Unit contains all three power supplies needed to run the ART13 Transmitter.(1.2kv)+(400vdc)+(28vdc)

    ART13 power supply was designed by W9KVK,N9SF & WA9FDO; Circuit Construction was N9SF(may hours) and the craftmanship is outstanding. Parts & Paint (WA9FDO) came from many sources, W9KVK came up with a way to use Microwave ovens (modified) for the High voltage transformers & Chokes.
    The complete project has taken approx. 6 months and many long hours resulting in a unit that takes the place of the usual Generator/motor sets used during WWII. Oustanding job by all team members. USS Indy radio is very proud of this accomplishement.!

  • TCS Transmitter & PS Progress  On the Air Capable!
  • Operating in the 1.5-12 Mega Hertz Frequency range, on (CW) continuous wave
    or (AM) amplitude modulation Radiotelephone modes. Power output was 25 watts.
    TCS gear was used extensively on patrol & Landing craft, reconnaissance vehicles,
    and similar purposes during the late 1940's.
