Hello all,

    Thank you Guenther for your solution to the AM coil matching.

    I also noticed a shifting in the tuning when building this circuit.

    By the way, to my surprise, the same circuit build with the NPN transistors performed better ! Something to do with the gain of the first transistor.
    As an experiment a few weeks ago, I used a higher gain transistor MPS-A18 and distant stations popped in loud and clear.
    I would love to build a transistor block with this high gain transistor.

    Just need to order an empty block one of these days.
