NOTES AND NEWS.
Reception. Have had to depend on contributed reports regarding reception last night. Am advised that conditions were in favour of good reception of the YA stations on the air. There was some fading and distortion of 2YA’s signals, but the others were O.K: The outstanding items of 3YA’s programme were the tine baritone contributions by Mr Rex Harrison. “ Aerial's ” informant adds: “Mr Harrison certainly vindicated the claim made for him by the A.B.C. that he possesses an excellent radio voice.’*
Complaint was made of the number of Oswalds on the air last night. The fervent hope was expressed that their howls were but the result of a last attempt to get the most out of their sets before closing down permanently with the end of the radio year. No one will regret it if these Oswaldian gentry fail to renew their licenses for the year, 1930-31. Not very much static was audible when the Australians were tested between 11 pun. and midnight. Station 2FC’s was the loudest, clearest and steadiest transmission heard. The A.B.C. stations devote quite a lot of their time, during their evening concerts, to radio plays, dialogues, and so on. Not very interesting, as a rule—at least that's how it strikes one listener. To be a success, a radio play csills for such very pronounced difference in the voices of the actors that the listener will have no difficulty in identifying the characters. Very, very few such plays have been heard during the past three or four years. And, instead of broadcasters learning from experience, the tendency seems to be to multiply the actors in a play, resulting in such confusion that one now automatically turns off a station that puts on a radio play. Election Results. Station 3ZC will broadcast progress results, as they come to hand, this evening, of the by-election held in the city during the day. :: k « The Pentode Valve. In spite of all that has Jjeen written both in the technical and in the semitechnical Press, there still appears to be some doubt in the minds of many listeners as to the functions of the pentode valve and its value in a modern receiving set. Most people are aware that the pentode is a power amplifier or “ output ” valve; that is to say, it is the valve the plate circuit of which supplies the power for operating the speaker. Now wherein lies the difference between the performanc of a pentode and that of a normal three-elec-trode output valve? In the first place it must be understood that to “ control ” a three-electrode valve of the super-power class, that is to say, to permit it to give its full output, it is necessary to apply to its grid a fairly large alternating signal voltage. Because the voltage swing in the plate circuit of the average detector valve available for application to the grid of the following valve is of the order of a volt or so only, it is necessary, if a three-electrode output valve is to be used, to interpose at least one stage of low frequency amplification between the detector and the output stage. By means of its special construction, however, the pentode valve will give its full output for a much smaller signal voltage than that required by a threeelectrode valve of equivalent output rating. This means that less low-fre-quency amplification is necessary between the detector and the output valve. As a matter of fact, in many domestic sets where only the strong signals from the local stations are required, a pentode can immediately follow the detector without intermediate low frequency amplification. The value of the pentode in this connection will be appreciated from the statement that the Mullard P.M. “ Pen tones,” for instance, have amplification factors ranging up to 82, as compared with about 4 to 6 for normal super-power triodes. At the same time, it must be remembered that a pentode should not be substituted for a super power valve in receivers which already give full loud-

speaker strength, for in such cases the pentode would undoubtedly be overloaded. If it is desired to use a pentode in such a set, it is advisable to incorporate some form of volume control or to add a switching arrangement whereby the intermediate low frequency stage can be cut out when strong signals are being received. Such an arrangement, of course, makes available a further degree of amplification which' will be of considerable help when receiving weak signals from distant stations.
WHAT IS STATIC? NO. 8. The biggest atmospheric actually measured by the English investigators was, they state, a mere matter of luck or rashness. But it may be interesting to record that an atmospheric actually drawn by Dr Watt at Khartoum during a spectacular thunderstorm produced a peak voltage of 250 volts in the aerial. While that same thunderstorm enabled Dr Watt and his companion to make some very interesting observations on the nature of lightning discharges, they regretted, they add in their report, that it had not since been possible to obtain more observations of the same kind. So much, then, for the shape of static. The next section of our subject concerns the counting of atmospherics —the number of “ blasts,” as it were, per second or per minute. We cannot do better than quote the report of Dr R. A. Watson Watt of the British Radio Research Committee on the subject. He writes as follows: “It may s<em ‘.a little exaggerated,’ as the French put it, to devote a whole section to the counting of atmospherics. Surely a pair of head-phones, a fiveshilling watch, a little patience, and this job is done! We used to think so, although of course we recognised that the sensitivity of the receiver came into the problem, as of first importance. Quite a lot of useful information was obtained while we still held this delusion : for example, we found that the number of atmospherics per minute heard in a standard receiver varied in an astonishingly regular fashion in the course of the day and the and. that there was a very intimate connection between the number so counted and the altitude of the sun over the horizon of the receiving-station.” (To be continued.)
