Adding loop antenna to pre-war radio

[Tamošius]

Thanks for the tips. I did figger out that I had the sensitivity knob on the back turned the wrong way . The only station it pulls in with a few feet of antenna is one local AM station about 10 miles away. From what I have read, that is all that one should expect? Next closet stations are at least 50 miles away. I don't care to tether the radio to a long wire antenna so gonna experiment with a loop and ferrite options. In response to Alex, shouldn't one go around the existing antenna transformer with a loop antenna?
