[Elecraft] [K3] Hearing aids, meet K3

That is the common misconception. Actually most AM stations go out to at least 10 and often 12 kHz (look on your P3). The exceptions are the stations transmitting an HD signal -- they are necessarily band-limited to 7 kHz. I boycott HD stations for that reason. I can tell the difference on a good wideband receiver.

I know this because I went through it in the pre-HD days with my senior advisor who had the common misconception. Even after I proved him wrong (by actually telephoning the chief engineers of KFI and KNX) he still gave me a 'D' on my senior project. Sour grapes.
