Thank you! That is exactly what I am shooting for in this design. The
prototype is just using an LM386, and the audio is quite good, but for a
marketable version, I wouldn't dream of using this chip. At the very least,
there will be separate bass and treble controls. The handle sounds like a
good idea, but I still have to work out the mechanical details for the
tiltable, rotatable loopstick.
As we speak, I am working on a homodyne detector, using a 1350 as a limiting
amplifier, feeding an NE602. I am not sure how it will work out, but it
looks promising. I have also decided to have an envelope detector in the
design, for people like myself that like that old time feeling of fading
signals!

Pete, best of luck with your endeavor. I'm sure that whatever you
come up with will be more than worthy, but here's my two cents
anyway:) What about the audio? If you could duplicate the deep bass
response and crystalline highs of the Grundig Satellit 600 and 650 you
would have a radio for the ages. That's what we all want, the best
listeners' radio which is also a superb dxing machine. A handle would
be nice also.
Bon Chance,

Yes, Marvin.................we will be marketing this receiver. Our
software
guy still has to write the programming code for the synthesizer, along
with
the code for the graphics LCD. I should have all of the RF design
completed
by the end of the month, so the ball will be in his corner. I am hoping
for
a March or April ship date, but you know how schedules can slide. As far
as
style, I am thinking of making it about the size of the Drake SW8. Let
me
know what you are looking for, folks!

Is there any other information available about this receiver?
Is it meant to produced commercially?

The MW receiver is progressing pretty well.................I have
completed
the synthesizer, and am now doing the final pass on the receiver
board
itself. MDS measures at .2uV right now, with strong signal handling
up
to
about 900mV.
Next week, I plan to design the sync detector, but there are a
couple of
things to keep in mind. If there are two closely spaced signals, the
stronger signal will capture the system. For this reason, I may also
include
the envelope detector function.
The initial results are very encouraging....................in the
"RF
Alley" that I live in, with three 50kW MW broadcasters, no overload
problems
were noted. I will keep all of you posted on the progress of the
design.
Pete
