After reading this thread I purchased a couple of HX 108_2 kits. These arrived very quickly and I built one today. I have built similar radios from scratch in the past so was fairly confident it would work. The kit came with 4 X 9018G transistors and 3 different ones. Upon assembly the kit worked first time but was very insensitive and audio output was low. The If transformers we quiet well aligned already and I proceed to align the oscillator and aerial tuned circuits. This is were I discovered the problem the aerial tuned circuit sidi not appear to be any where near resonance. I will take a look at it later.
