RADIO FITS FOR HAIDA's TRIBAL SISTERS


The data in the tables below was extracted from BR299, a Royal Navy publication dated 1947. Photos and specs for most of this equipment can be found in this document . HAIDA's radio fit is also shown here just for comparison.  For receivers,  only the types are shown but no quantity information. The numeric suffixes which appear for American made equipment, denote the procurement contract number. A TBL-4 is identical to a TBL-12  but was made under a different contract number or even a different contractor.

Some items of interest:

1) There is one commonality to note here. All the ships shown had the Deco QH3 receiver fitted.  In order to keep the system a secret from the German military, the Decca transmitters  were set up in the UK and turned up on June 5/44 for D-Day and shut down on June 7/44, some two days later. Decca could not even be used in UK waters for the duration of WWII and then some. The Decca Navigator Company was formed in 1945 but it wasn't until 1946 that the first commercial chain came on the air. Since the Canadian Tribals were back in Canada after war's end, the receivers would not be of any use on the Canadian side of the Atlantic even if Decca was up and running. The reliable range of this system was only 250 nm.  The QH3 became known as the QM set in the Royal Navy after 1945.

2) Micmac is the only Canadian built Tribal that has a radio fit in BR299.  By 1947, radio equipment from Canadian Marconi started to find its way into HMC ships.

ATHABASKAN (G07)
g07_main_wireless.jpg
This was Athabaskan's (G07) Main Wireless Office. Note the enclosure within the Wireless Office whose main occupant was a aerial coil.  It is not known whether it was used for perhaps LF transmissions.  The port passageway is at the top while the forward bulkhead is on the right. ATHABASKAN was sunk Apr 29/44, so no equipment is listed in BR299. This is the only info so far. (Drawing source

Athabaskan G07  - 2nd Wireless Office layout. At the top of the image are two HRO receivers. Some of the labelling is illegible due to the quality of the source drawings.

ATHABASKAN (as DDE219)

 No radio fitting information is available since Athabaskan commissioned in 1948. It was out of range for BR299.
CAYUGA (R04)
No radio fitting information is available. Cayuga was commissioned in 1947 so information about her radio fit may have missed the publication date for BR299.
