Success of the Booster W. E. DANCE (Blenheim) writes: * I have built up the R.F. unit as described by J.H. in this week’s "Radio Record." I have much pleasure in stating that it is very much better than J.H. claims. I had no trouble in making the coil and assembling the booster. On the first try-out last Wednesday night I logged the following stations with great volume :-7ZL, 38AR, 4YA, 2FC, 4QG, 8L0O, 2BL, 1YA, 38YA. On Saturday. afternoon the 1ith I received 1YA and 3YAyon the speaker at quite good volume# I haven’t had very: good results on stations below 83YA. The aondenser vanes are right out. Am I correct in this respect? I wound on about forty turns of No. 24 for the secondary and sixteen turns for the primary. {It appears that there are too many turns on the secondary. ‘Try a reduction to about 35. The attention of constructors is drawn. to a query in Questions and Answers last week where it was pointed out that under certain conditions the booster would cause trouble, The aerial coil must in no wise be connected with the grid coil.] .
