Parallel Feed B.D.

‘(To the Editor.) I HAVE been experimenting with an -old parallel feed B.D, circuit. I have added a push-pull stage and made a few other changes to the variable condensers and coils, and the result has exceeded expectations, and in my opinion is as good as any 5 or 6-valve electric set. On June 3 I was waiting for Auckland to come on the air, so that I could neutralise the set, when I heard someone reading out the cricket scores from England. Imagine my surprise when the announcer said 2YA, ‘This was easily heard all over the house. At 4 pm. the same day I logged 4YA, and the next day at 4.30 pm. 2BL. This may appear nothing unusual, but as I am only 20ft. above sea level, it must be conceded that this performance is good for a set of this type. My aerial is no good as it is only a temporary one. All the above-mention-ed stations were at excellent speaker Strength, and 1YA roars in during the daytime. Mercer is 40 odd miles from there, and entirely surrounded by hills. I shall gladly furnish further particulars if anyone is interested. I am sure this set will give their DX work a considerable lift-L.H., Railways, Mercer,
