Hon. D.P.V.

My original report dated 31/3/28 provided

for additional transmitting plant, automatic

transmitters, a mast and sundry alterations and

additions to buildings at Capo D'Aguilar.

2. The report was based on the assumption that

the transmitting plant would be installed at D'Aguilar,

thus contralising all transmitters there, and using

the Eyrie as the receiving centre.

3. Since writing that report short wave working

between Hong Kong and South China has been introduced, and a defect in the D'Aguilar site i.e., the screening caused by the hill immediately bohind the station is found to be so serious as to necessitate re-arrangement 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.

5. It may at first be thought that if only Canton and South China is eff cted that this could 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 di tant stations, for example
