Hi Mike,

Despite the dire warnings of the other person who responded to your request,
I've done the MW attenuator removal for an IC-756Pro and it works great to
improve the trans-Pacific MW DX I hunt for. The attenuator is the same in
both the IC-756Pro and the IC-756Pro2, so I'm going to send you files via
email that should help you out.

In fact, I'll be performing this mod on a friend's IC-756Pro2 soon. He's
also a foreign MW DXer who bought the transceiver just for it's excellent
receiver section (like I did).

I need to give credit to Dallas Lankford (an electronics prof. at a college)
who figured out the mod. The file with the schematic was done by Dallas, and
I created the file which shows the component layout. I also have Dallas'
modification for enabling the preamp on mediumwave if you want it (I have
not done this mod, as I already have a high-IP3 Wellbrook preamp inline
after my antenna splitter).

Dallas Lankford is definitely not an inexperienced tinkerer; he's one of the
two most brilliant people in electronics that I know personally; the other
is my good friend Craig Siegenthaler at Kiwa Electronics.

All you need to do for the attenuator mod is to carefully remove one SMD cap
and one SMD resistor, and add a short jumper wire (I used wire-wrap Kynar).
The mod took me less than 1/2 hour to perform. It's supposedly good for 10
or 11 dB gain.

The mod definitely helps the 756Pro series to hear weak MW DX better... mine
is now in a virtual tie for MW sensitivity with my modded R-75.

BTW, I use 450 ft. and 700-ft. Beverage antennas at home, and have found no
adverse effects from the mod, despite a number of S9+60db local transmitters
in the area. I live in a high-RF area near Seattle/Tacoma and the
trans-Pacific (and rarely European) mediumwave stations are still heard
here. The MW attenuator removal mod has helped, not hindered.

I've removed MW attenuators in an IC-R70, an R-75, and now a IC-756Pro. In
all instances my DX reception improved. The foreign MW DX on mediumwave is
often weak, and sensitivity is frequently a major issue. I've DXed these
foreign MW stations for 15 years, and have found this consistently to be the
case. Overloading & images have been rare with these receivers as-modded,
and if they do crop up and/or interfere, it's a simple matter to add
attenuation as needed, reduce the RF gain, or both.

Hello all



I have been searching high and Low for a mod that removes the Medium

Wave band attenuator. If anyone out there knows a site please direct

me and e-mail me direct I would greatly appreciate it.
