Pitfalls Among New Wavelengths?

To the Editor. Sir-In looking over your article on the new wavelengths, you say that 2YA will be exactly half way between 2CO, Corowa and 7ZL, Hobart. On referring to the Call Book I find that both 2CO and 7ZL are on the same frequency, namely, 560 k.c., and the new 2YA frequency is 570, so it cannot be between, unless the Australian frequencies have been altered, or are going to be altered. I notice that 1YA’s new frequency is 650, and 2FC Sydney is 655, only 5 kilocycles separating them. Will that not be too near to get good reception of 2FC. If the Australian frequencies are going to be altered could you publish them in one of your issues?-I am. ete..

-Wellington. [Your Call Book is evidently well out of date. According to our latest Summer Bdition, 2CO operates on 560 k.c., and 7ZL on 580 kc. Thus 2YA's new frequency570 k.c.-will be midway between these two. 2IC operates on 665 k.c., not 655 k.c.,, ‘and’ so no difficulty should be experienced

in separating this station from 1YA, on 650 k.c. As far ag we know, the frequeneies of the Australian stations are -not going to be altered,-Id.]
