Hon. D.P.W.

My original report dated 31/3/28 provided for additional transmitting plant, automatic transmitters, a mast and sundry lter-

tions and additions to buildings at Cape D'Aguilar.

2. The report was based on the assumption that the transmit- ting plant would be installed at D'Aguilar, thus centralising all transmitters there, and using the Eyrie as the receiving centre.

3.

Since writing that report short wave working between Hong Kong and South Cina has been introduced, and defect in

the D'Aguilar site i.e., the screening caused by the hill immediately

behind the st: tion is found to be so serious as to necessitate

re-arranegment of the scheme.

4. Information as regards the screening effect of high lands when using short waves is at the present moment very unreliable, and no data appears to be generally accepted, so each station must actually overcome its own difficulties, chiefly by trial and error.

It may at first be thought that if only Canton and

5.

South China is effected that this could be easily overcome by building a small station to deal with this traffic, and actually this has been partly effected by installing a small transmitter at Victoria Peak, in the "Eyrie Quarters", but it is not only Canton and South China, the screening that affects Canton, affects more distant stations, for example London lies very much on this line, and so something more than the accommodation that can be

provided at the Eyrie is necessary.

6. In my revised estimate for 1928 I now substitute two one hundred foot rests for the Peak in place of one 200 ft. at D'Aguilar and in place of alterations to buildings at D'Aguilar

I recommend
