Willing to sell one of the "Current": units??
Also, you say you are in Chicago. What side of town? I get to Chicago on a
weekly basis.

I was thinking about using 1kHz tuning; this way, the radio would be more
universal. No need to worry about 9 or 10kHz steps if this is done. With
my current units, you can connect an untuned 6 foot loop directly to the
the
50 Ohm antenna input, and the results are pretty dramatic. From my
location
in the Chicago area, I can receive WLW, on 700kHz, with an S8 signal
level.
WJR, on 760kHz, comes in at about an S7, while on 610kHz, I can receive
Kansas City Missouri, and the Ohil station fighting each other, at an S7
signal level. If I want to listen to MW, I don't even bother using my
AOR7030, Palstar R30, Icom R75, or Yaesu
FRG100...........................none of them is as hot.

I would prefer a table radio like a Tivoli or old KLH21
Ceratinly some DRM capability, or a place to add a plug-in card which
could be
either DRM, C-QUAM stereo, or the digital AM (IBOC or Kahn?).
Depending on how the digital standard goes, at least the RF could be
constant.
10/9 khz tuning (US vs Euro)
Noise blanker
Before I implement a noise blanker, I want to develop a NB design that I
have been slowly working on..............this would be a Quadrature type.
The advantage to this type is that it would have dynamically variable
blanking width, with a null of right around 50dB. Still working on that
one
An input for a loop antenna
An input with DC phantom power for an outdoor active antenna
Maybe an antenna switch to switch between lop and other antenna, or two
loops.
Good tone controls
Perhaps something like the old Scott DYNAURAL circuit which shaped the
flatness
of the audio depending on signal strength, or something like Worcester's
AM
circuit which made the IF passband narrower as the signal strength
decreased.
Good speaker!
Amen!
