106 REPORT OF THE No. 3 



The change in rates is as follows: 



Old Rate New Rate 



50c for 1 to 10 words. 70c for 1 to 10 words. 



$1.00 for 11 to 20 words. 5c for each additional word. 

 10c for each additional word. 



This change had the effect of encouraging the public to make greater 

 use of the system, and in spite of this reduction in rates the revenue was some- 

 what increased. 



Aircraft Radio 



A 35-watt radio-phone transmitter was installed in the moth at Sioux 

 Lookout with satisfactory results. 



Tower Service 



The use of low power ultra-high frequency radio-telephone was introduced 

 between the Batchawana and King Mountain towers in the Sault Ste. Marie 

 district, and the end-of-season report showed that reliable communication had 

 been maintained throughout the season. 



Improvements 



Owing to the pressure of work at the Sioux Lookout station and in order 

 to eliminate the necessity of two stations at that point, the outlet for com- 

 mercial traffic was divided between the Sioux Lookout and Kenora stations. 

 Consequently, instead of maintaining three operators at Sioux Lookout and 

 one at Kenora, there are now two operators at each of these points and a 

 continuous service of sixteen hours daily is provided. 



A building to accommodate the radio equipment at Hudson was taken 

 over from the Department of Northern Development, and moved to a lot 

 previously reserved for radio purposes by the Department of Lands and Forests. 



New Equipment 



The purchase of new equipment, all of which is to be installed during the 

 coming season comprised the following: 



(1) Four 300-watt radio-telephone-telegraph transmitters and receivers, 

 which will be installed during the 1936 season. 



(2) One complete aircraft installation. 



(3) Parts and material for the construction of sixteen ultra-high frequency 

 radio-telephone sets, which will be installed during the 1936 fire- 

 fighting season. 



(4) Parts and material for the construction of one portable radio-phone 

 transmitter to be installed during the 1936 season. 



Developments 



As a result of a satisfactory performance of the ultra-high frequency sets 

 in the Sault Ste. Marie district it was decided to carry out tests in the Sudbury 

 and North Bay districts. 



This was done with such encouraging results that work was commenced 

 on the development of suitable equipment for inter-tower communication.
