BROADCASTING.

TO THE EDITOR. Sir, —I was interested to read the letter in your paper of yesterday’s date complaining about interference _ with other stations from 4YA. In fairness to our local station I may say that I approached the station on this point, as I was experiencing some interference on my own set. I was given the following illustration of the “ sharpness ” of the station’s transmission;— An ordinary set, such as is sold to hundreds of people, was taken out to the big mast at Highcliff and 4YA tuned in. 4YA was then tuned out, and 3YA tuned in. There was not the faintest suspicion of interference or background of 4YA while 3YA was being received, and this applied to all the other stations that were brought in. This was a convincing demonstration to me, at any rate, that the fault lay with my Bet. I am sure that if- “ Ravensbourne ” approached the station in the same way it would accord hipi the same courteous hearing. I also remember the correspondence of some little time back on this same subject. At that time a person signing himself “ Radio ” replied in much the same terms as I have had pleasure in doing to-day. It is evident, therefore, that tests have been frequently carried out proving that the transmission from 4YA’s new transmitter must be razorsharp.—l am, etc., Roslyn. January 10. TO THE EDITOR, Sir, —Several letters have, appeared in your paper about interference by 4YA since the new station came into operation, and on January 9 “ Ravensbourne ” claims that it must bo the fault of 4YA transmitter. In this I think he is wrong, as I have had the opportunity of hearing several radio sets in various parts of Dunedin, and all have been able to cut 4YA out quite easily. My own set is a 5-valve superhet., and I have also had it in various, parts of Dunedin, and I can get 2YC Wellington without a trace of interference. Oii my set 4YA is 80 on the dial and 2YC is 84, so I think if there was anything wrong with 4YA it would blot out 2YC, there being only four degrees

separation between the two. So I think it would be wise to make certain it is the station before getting ready to tear it to pieces. The new station, in my opinion, is a credit to the board.—l am, etc., „ Aeroplane Dial, January 10.
