Hi Kent,
I am up in Mount Prospect; if you want to come down and
audition one of the current units, that would be ok. I still have to work
out the details for a high level AGC loop, and I am also working on a low
noise synthesizer for the next generation, but feel free to shout me down
when you are coming to town. Hey, have you ever made it to the Madison
DXer's gathering? One of the fellows has moved to Milwaukee, so the next
gathering will be in that town. This last one was pretty good, although I
didn't make it. They did have some well known folks up there, such as Gerry
Dexter, Neil Katsiros, etc.

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!

Pete

I have been to a few of them, but not as many as I would like to. They are
nice gatherings!!

I will email you direct so we can talk further!

That sounds good, Kent. I may have met you; I started coming over there,
when I was still working for Rockwell-Collins, I think, back in 1998. It
was over at Bill D's house.
