Excluding mega-buck military or maritime radios, the legendary Drake R7A is,
in
my opinion, the BEST solid-state MW DX radio ever made. If you can find a
used
one in good condition, grab it. I have one, and will NEVER part with it.

I had both the R-7A and the HQ-180 at the same time. The R&A is superb, but its
audio made it hard to ID stations, but it could sure dig out the DX; it is
still regarded as the best radio of any type for the "tropical bands" 2-4 MHz.

The HQ-180 had superb audio, and DX "dig" ability. But not great on frequency
readout.

BTW the Skanti 5000/5001 is the equal of the R7 in performance. It's what I use
now for AM DXing.

I assume you're looking for a desktop radio.

I think you can do better than an R75 for MW.

Get a Drake R8B if you can afford it. It's got an excellent synch detector. If
price is an issue, the Palstar R30 is supposed to be a superb (albeit no bells
or whistles) MW radio for it's price, which I believe is cheaper than an R75.

Or the R7, it's the same radio. (Though R7A's always seem to command a higher
price). Hanging on to mine also.

I have the 8, 6, 4, 3 and 2.3 filters in mine.

The R-75 is SO sensitive that the MW area has something to attenuate MW
signals;
So you don't get overloaded from local statins
However;
R-75 does Work pretty good with an external antenna.

IF you're just after MW, Suggest getting
something else & an external / Justice / Loop antenna

I've been able to pick up New York Stations in The Bahamas if conditions are
right..
on a truly Junk Shortwave radio

I think antenna and Lack of local noise are the real issues,

Hi Russ:I have removed the attenuator and did the Pete Gianakopoulos'
Advanced MW Attenuator bypass mod and the R75 now shine in the MW band
sensitivity area without using the 2 pre-amps that the R75 have.But
with a good external ant or MW loop like the quantum/justice/kiwa or a
big homebrew MW loop and using the pre-amps you will not have any
problem picking up a lot of far away or weak stations with an stock
R75.An remember that the R75 include a lot of features to help in the
signal intelligibility.The most critical factor in MW dxing is to have
a good antenna and the knowledge of how to use it.I have a K9AY
external MW loop and I recomend it if you have at least a 30 square
feets space in your backyard.For my CCradio plus I use a justice
[Crane co] double coil ferrite ant with very good results...

The K9AY is a good antenna. Is your antenna amplified? How is it
configured? Do you have two or four loops?

The K9AY is comparable with a beverage ant in some cir****ances but
with less noise and betters nulls.I have a 30 db pre-amp designed from
a online project.My K9AY configuration is a copy from this site
http://www.aytechnologies.com/TechDa...Install.htm.My ant have 2

30 dB is a lot of pre amp. Have you expierenced any overload on your
radio or any other problems from that much gain?
