Default Drake R8 question

That appears to be very true. I tried the R8 out with the RS passive loop,
and if definitely needs a preamp in order to have good sensitivity. This is
where the R8 A and B has an advantage since you can enable the preamp on all
ranges.
With a long wire, or an active loop antenna, it is pretty good.

I may be picking up one of these things tomorrow. Looking at the input
bandpass filter schematic, I notice a T type of attenuator that consists
of two 270 ohm series resistors, with a 330 ohm shunt resistor on the MW
filter section.
Am I dreaming, or did Drake really dumb down the design with a full time
attenuator on the MW band? If this is the case, it looks like I have yet
another project.
