    My another version of MW receiver with an old look. There you can see the strange big remotely tuned loop antenna for DX listening. A worthy construction!

    Packed inside my first DMM case which burned out while experimenting with high voltage! I'm proud to give him an extra life through singing and entertaining me;)

    Only use it for hearing to dramas..:p

    Here's some pics of a MW/SW superheterodyne receiver I built some years before with an odd look :D. Please note the SW fine tuning lever on the front end.

    I think I made it little complicated..

    Works great!

    Hello,

    If you mean a BF199 then I think they are almost identical HF transistors. Sometimes back I tried for it with no luck(rare?). A few HF transistors might without changing the biasing I guess.
