The following table is a blend of three radio call sign lists. Call signs with assigned frequencies and emission types were extracted from a list of RCN shore stations around 1948. Items marked with an asterisk (*) were assigned frequencies or call signs but not yet in use in 1948. Some were reassigned later.

Document BR619(2) provides information from WWII which was overlaid on the 1948 list. It  illustrates two things. Some of the shore station call signs were used during WWII only and retired at the end of the war while other call signs remained with the shore stations that were still around in 1948. Using CCNO 1-575 date January 1, 1945 further verifiactions of the call signs were made.

Reference is also made to CCNO 575-1 (Edition 1945). The long title of this publication is known as "Canadian Confidential Naval Orders". It contains orders numbered 1 to 575. The short title printed on the cover is "CCNO 1-575" but individual orders are referred to by their specific number.  Example, the CCNO referring to the W/T station at St. Pierre would be referred to as CCNO 107. The CCNO entitled "Call Signs of Royal Canadian Naval W/T Stations" would be referred to as CCNO 411.

Another set of call signs was found in an  ITU call sign publication  - 4th edition, January 1970. These have also been applied to the table and indicated with a note "ITU Listing". As a precaution, there may be errors in the call signs denoted by "ITU Listing".

The goal here is to illustrate the history of call sign assignments for shore stations..

Thanks are extended to LCdr David J. Freeman, CF (Ret’d) who provided a copy of BR619(2) and to Spud Roscoe who did the analysis of it in order to make more sense of it.  Updates for stations which saw service after 1948 were provided by Douglas Stewart.

NOTES:

1) Douglas Stewart <dougjoy@ns.sympatico.ca> adds the following: "When HMCS Labrador was a naval vessel, (later changing to the  Coast Guard) she was an escort for the Dew Line convoys during the mid-1950s. Because of the very poor communications condition in the Northern Latitudes, Churchill was assigned ship/shore/ship responsibilities during  hersummer deployments as a supplementary function.

2) Established Aug 1, 1943. Became HMC NRS Dec 1, 1950 to July 1  1956. As HMCS July 1 /56 to July 11 1966. Became CFS Churchill

3) Est 1949. Became HMC NRS  1953-61. Tender to Gloucester. Moved to new site and became Inuvik.

4) Established as HF/DF station in WWII; HMC NRS 1949-1956;  HMCS  1956 - 1966. Became CFS Coverdale.  Closed 1971. CGT was Coverdale's call sign from 1949. It was changed to CKT in 1953 or 1954 because operators were running the characters together and CGT came out as CQ.

5) Note 5 deleted.

6) CFI was NRS Chimo's call until that station was closed in 1953. Frobisher assumed the call when it opened in 1954.

7) CFL was Gaspe's call sign during WWII and became Churchill's call sign in 1949 until it closed in 1968.

8) This station was used for Morse Code receiving practice while ships were alongside. CKB replayed the tapes that CFH had used and CKR replayed the tapes that CKN had used. A  Marconi CM11 was used for these transmissions within STADACONA/NADEN.

9) The new spelling of Masset has one 't' only. The old spelling had two tt's. In 1949 NRS Masset (which had been abandoned in 1945) was opened as a HF/DF station. The station was hit and damaged by an earthquake in August 1949.

10) Per CCNO (Canadian Confidential Naval Order ) 1-575 dated January 1, 1945. After WWII, this call sign was reassigned.

11) Per CCNO 107  (R.O.)  (26-12-42)  (N.S. 1008-12-6) . There was a CNOIC (Canadian Naval  Officer in Charge) at St. Pierre, so this may explain why a French  callsign is being listed in a Canadian Naval Publication.

12)  Canadian Confidential Naval Order (CCNO)  358 authorizes the following signal publications  to be held by the  Senior Naval Officer, Goose Bay and the Officer in Charge, Rigolet, War Watching Station

 Naval Code and Decode with Recoding Tables (SP 02358 Series)
 Mersigs. Vols. I, II and III with Recoding Tables (SP 2272 and 2404 series)
 Indicating Groups (SP 2169 and 02509 series)
 Signal Letter Index
 Ship Index

In addition Rigolet holds:--
 Mercantile Secret Call Signs
 U.S. Mercantile Secret Call signs
 Key Memorandum No. 6
 C.B.'s 3057 and 3060 series
 B.R.'s 69, 70, 98, 266, 619 and 777.
 (R.O.) (1-7-44) (N.S. 11867-1)

13) This station provided communications for the Northern Sea Lift in the summers of 1961 and 1962 (confirmed).

14) Page 32 of the February 1950 issue of Crowsnest Magazine carried this item. "CKZ Calling. The Victoria naval division, HMCS Malahat is anxious to work other naval divisions by W/T on Monday evenings from 2000 to 2200, PST, using the transmitters and receivers in its headquarters and training ship, the minesweeper Sault Ste. Marie. Malahat has been allocated radio call sign CKZ, operating on the following four frequencies: CKZ24 on 2410 kilocycles, CKZ79 on 7985 kcs, CKZ94 on 9480, and CKZ 35 on 13510".

[15] Spud Roscoe comments. "In the 1950's when I was in the navy we used to keep one ship off Shelburne and an Argus A/S aircraft (based in  Greenwood NS) off Shelburne as well. The navy had water microphones situated there which could detect any any vessel passing over these microphones. The Argus was to have CW contact with either the ship or Shelburne at least every 15 minutes."

The now defunct South West Shore Development Authority acquired CFS Shelburne in 1999 and sold it in 2008 to Seacoast Entertainment Arts Inc. for development as a film production studio. Seacoast eventually went bankrupt and the property was sold to a Yarmouth developer, namely  Roger Sullivan on Nov 24/11.
