Hi,

I mostly do MW listenign/dx'ing. I would be interested in feedback
on how well the R75 performs on MW. I know there are Kiwa mods to
increase the MW sensitivity. Are these really necessary? Is the
difference that dramatic?

Well anyway, I would be interested in any user input on the R75.

Thank you

Hiya... I have an R-75 and I like it quite a bit, but not for MW. It is
sensitive enough and works just fine on most MW, but if you want to DX a
weak MW signal I find that the R-75 is too noisy. Way too much snap crackle
and pop. I use a GE SR-III for MW DX'ing. Because it is analog it is quite
as can be. The draw back is that the tuner dial is not accurate at all.
I've read/heard that the CC Radio Plus is better then the GE-SR series
because it has an accurate tuner. It may not be as sensitive as the GE-SR
III or as quite, but it is probably one of the best MW radios available. I
also know that there are a lot of people that use old analog tuning
automobile radios as their MW DX'ing radio but I wouldn't know about which
ones to use or how to get them...

So... For MW, you have way better choices then the R-75. The R-75 shines
for sw utility and sw DX'ing using ssb and ECSS tuning, but it isn't
regarded as a MW radio.

Hope that helps...

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.

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.

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

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.

Here's a suggestion, hit a swap meet (or ebay) and get 1) rf signal
generator and 2) a (digital) frequency counter. When you're lost on
the SR-III, (turn on and) adjust the generator (with the counter hooked
up and working) until you get a heterodyne and then just read out the
frequency.

The same thing could be done with a second receiver with a digital readout
using the local oscillator, remembering to compensate for the IF offset.
I can do this with my R-1000 because is leaks a signal 455 kHz above
the received frequency. (It's not the LO, as the R-1000 first IF is
45.something MHz. It's the signal used to drive the digital readout.
The frequency synthesizer board in the R-1000 is pretty baroque).

Don't know if anyone mentioned removing the R-75's mw attenuator, which should
help make the R-75 more amenable as an mw dx tool. Antenna orientation is a
factor, also. Have a 130 ft. of 16 gauge wire, ground terminated for a
beveredge effect. Is most efficient bringing in Bay Area & SoCal am'ers. But
it's a bit deaf snagging Denver's flamethrower KOA , however.

That is a nifty idea.... I wish they would just make the thing accurate ....

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,
