To the Editor of the "Mobru-Chixn IOnu News"
Sm,—Regarding your item "Ban-doong on the Air" under the heading "Through the Mike" in your yesterday's issue, I should like to give Some additional information.
Not only can this station be heard on the 29m band, but also the 19m, the 27m and the 31m wavelengths, although the reception on the latter band is frequently poor, probably due to the "crowding out" in that section. T have always found the 19m reception the best of all, so much so that after 9 pin. local time, when Daventry and Berlin gradually diš- appear from the "picture", Bandoeng continues to come through with almost undiminishing strength. 'Transmission begin at 6 p.m. and end at 11 pin, both Java time which is exactly half an hour behind Shanghai time, except on Saturdays when they finish' an hour later.
The NIROM, as this broadcasting system is known in the Archipelago, also often relays programmes from the Philips sender PHOHI in Holland. These, however, can occasionally be picked up direct, most times on Wednesday nights after 9 pin. on a wavelength of 19 metres, Finally a question. In your article you refer to Bandoeng relaying YDB; what do these initials stand for? I suspect them to be part of the Ham vocabulary and should be' glad to know their meaning.
Puor Shanghai, Jan.
*YDB is not part of the Ham vocabulary, but the call-letters of the medium-wave radio station,
