Equipment specific to the 1950's period is listed in this document. Equipment not described elsewhere in the web page will be featured here.

In the 1949/50 period, destroyers had a TBS set (60 to 80 MHz) for the principal manoeuvring circuit, and the TDQ/RCK (100 to 160 MHz) for the Plot/AIC/CIC circuit. There were other circuits for purposes of air communications.

Lt. Cdr. Frank J. Dunbar reflects on this period. "It wasn't until the advent of UHF that we had the equipment to guard several circuits. HAIDA was the first RCN ship to be fitted with UHF. We were assigned in the fall of 1949 (or possibly 1950) as the token Canadian presence in a USN Task Force that was to conduct an amphibious operation in Labrador. The arrangements for the exercise had been completed with the UK, but when Newfoundland became part of Canada, we had to at least take a token part. It was a 50/50 chance as to which ship was chosen, because only HAIDA and MICMAC were in commission on the East Coast. However, the USN had gone completely to UHF by then, so we were sent down to Norfolk Virginia to have a couple of UHF sets (URT/URR) installed just for the exercise.

I remember that we had next to no air information in the exercise, let alone shore bombardment circuits. But we did get fresh white bread from the freezers of the USN supply ships,  and fresh cod which came from jigging over the ship's side. Which leads me to think that only one TDQ/RCK was left in each ship during the UHF conversion in the early 50's in order to communicate with other users (primarily civilian) who were on VHF only. The major problem was always to get the right crystals, since the TDQ/RCK combo required the use of crystals".

Many equipment types shown in HAIDA's Radio 1 and 2 documents  and described fully, were also fitted in September 1955. These are not described here in the interest of simplicity. Only links to the photos are provided.

Portable Radio

An Athabaskan crew member uses the WS-58 portable set. Uses included short term communication between ships for such jobs as jack-stay transfers, underway fuelling and practice shoots. (Crowsnest photo, December 1950)

The WS-58 Mk1/T set was the Navy's portable radio until replaced by the CPRC-26 set around the mid 50's. It was a man pack transceiver developed in 1943 for use by the Army.  Frequency range 6-9 MHz. RF output 0.3 watts. MO control. R/T only. Range up to 5 miles. (Photo courtesy Wireless for the Warrior)

A report on HAIDA's radios dated October 1955, indicates the following deficiencies.
1) The ship has insufficient VHF/UHF channels for use in large scale exercises.  Any equipment failures only worsen the problem.
2) The antenna multicoupler (model not identified) is considered inefficient and the lack of an aerial patch board impacts reception capability.
3) Radio 1 and Radio 4 are heating excessively due to an inefficient ventilation system. This is believed to be inducing equipment failures. During summer months, temperatures of over 90F have been recorded with a consequent hardship on operators.
4) During major exercises, a 24 hour watch is maintained in the Crypto Office. At times it is necessary to have two operators closed up. Due to cramped quarters and poor ventilation, this has proved to be an unsatisfactory arrangement.
5) The intercom fitted from the bridge to the flag deck is inefficient due to the exposed position of the intercom boxes.
6) Light leakage from the two 10 inch signal projectors prevents the "Nancy" (IR) gear from being used.
This is just a small sampling of the pesky problems that were experienced aboard ship.

 

Hardworking Radiomen on watch. This scene was typical in Radio 1 in 1956. (Photo courtesy HMCS HAIDA archives) In this photo,  the walls of the Message Centre have not yet been erected. The vent trunking appears to be all metal and  lacks the wood veneer that is visible today. The metal desks that we see today are not present. At each operating position is a goose neck lamp and a Remington typewriter. Other than officially sanctioned photographs, it was against regulations to photograph any area of the ship. If it wasn't for these clandestine pictures, scenes such as this would be lost forever.

1956: Judging by the smiles on their faces, these Radiomen must be thinking about their next shore leave. Seated from left to right are Jim Benson as ABRM - now deceased; Neil McAskill as PO2, now retired as CPO2. Jack Wells as ABRM, retired as LCdr and now deceased. (Photo courtesy HMCS HAIDA archives) In 1955, HAIDA carried a complete complement of eight CV's and eight CR's along with two CS ratings.

LF Reception

Ronald Yaschuk explains the purpose of the Model TE-236 LF receiver fitted on the starboard bulkhead in one of the photos above. "The LF setup in ship's at sea was designed to copy the submarine broadcast, either at normal speed or a high-speed burst. When the submarine was submerged during an exercise, it could not copy the broadcast since LF does not penetrate seawater. Hence. the Commander of the Task Force, Task Group etc., designated one ship as SUBMARINE GUARD. This was also laid out in the OPORDER Exercise Book. If your ship was tasked with this duty,  you copied the submarine broadcast as well as the fleet broadcast. It was not a pleasant job as I recall, but someone had to do it.

When the submarine surfaced, the Guard ship would rebroadast  the the information to the submarine. Low speed broadcasts were fairly reliable but the high speed burst could be obliterated or garbled by static or interference  If both the sub and the ship missed the broadcast, you waited until the next designated broadcast period.  If anything critical was missed that left the ship and the sub scrambling to obtain the the required information for the next phase of the EXERCISE.  In addition, PL (plain language) sent to the sub had to be buttoned up (encrypted) and sent by CW which took a considerable amount of time. Meanwhile, during all of this, you had the C.O, OPSO an COMO hanging over your shoulder making things even more difficult".

Transmitter Key Board

The transmitter key board  held only the keys that belonged to the radio transmitters. Any radioman who had to perform maintenance on an antenna would take the key off the board, then use it to disable the transmitter thus making it safe. The man aloft keyboard (for radars) was held in the Wardroom and was controlled by the Officer Of the Day (OOD). A sign in/out log would  tell him who held the keys. By 1962, the both radar and radio transmitter keys were stored on the Man Aloft Board which was mounted in the Message Centre aboard HAIDA.

The transmitter key board or man aloft board in many ships was usually made by one the shipwrights in exchange for a favour like a few tots of rum. It was usually made from mahogany or any other wood which was handy. Key identifiers and numbers were etched on little brass plates and the inside of  the key board was lined with a green felt cloth.  Key boards were also made of aluminum with a lockable hasp. They did not look pretty but served the purpose.
