NRD-515 MW attenuator
 

Can you believe it? They actually put a full-time attenuator in the MW
range. That's why when you tuned from 600kHz to 599kHz the signal came up.
It's because of the 5dB attenuator. Out it goes!

I just finished removing that attenuator. Now, there is only a 3dB
difference between the MW range and adjacent ranges. This would make sense,
since Varactor diodes don't have quite the Q that the other filter ranges
would have, with their silver mica caps. It's definitely much better now.
