The Palmolive people were responsible for most of the items during this period. Later on 2XG, on about 33 metres, was heard on his word tests-‘Write down--."’ _ REM was on the air during the eyening. Sunday, April I, On Sunday morning I got up early enough to hear the conclusion of the programme from PCJJ, the last item being the Dutch National Anthem, sung by a choir.

6AG, Perth, was testing, and concluded the musical portion of his test at 1.17 a.m., West Australian time. KDKA was again weak, and — spoilt by morse.

Thursday, April 5. On Thursday morning the talk was apparently from Chelmsford, as I did not hear the clock or "London calling," hut the announcement, "SSW, Iixperimental station, Chelmsford, MngJand,’’ At 10.30 p.m., a stranger was tuned in on about 80.5 metres. This proved to be a Japanese station relaying the programme of JOAK, as that call was heard several times. ‘The call of the short-wave station was not heard while I was listening from 10.30 p.m, till about 10.45 p.m. It was probably JHBB experimenting on a lower wave than they used on previous tests, Friday, April 6. ° PCJJ was heard at good strength aud modulation till they signed off at 6.35 a.m, 5SW and 2XAD were having a chat, The latter station could not be picked up direct, and only faintly heard through 55W, London was heard through d5SW from 6.30 a.m. till just before they closed dowit, Till 8.30 a.m, they were audible on the speaker, volume gradually getting weaker.
