I just bought a new Icom radio. It seems to be awesome for tuning
around the ham bands in LSB. But when tuning for Shortwave broadcast
programs in AM it doesn't seem as listenable. Do I need to have my
Icom modified? Kiwi mods? Any help appreciated. Please keep it simple.

If you have Kiwa do the work you don't have to solder.

As you have discovered the R75 is a capable SSB receiver but not so
good for AM broadcasts. There are several modifications you can pay
Kiwa to make on the radio so it will perform better on AM broadcasts.
Here is the link http://www.kiwa.com/R75.html

Here are some of the upgrades you might consider:

Synchronous Detector Upgrade $45.00 Audio Upgrade $35.00 High Fidelity
Audio Filter Upgrade $35.00

The filter issue is a little tricky with this radio. You will need to
maintain a filter ~ 2.4 to 2.8 KHz for average SSB conditions and you
will need to have one at ~ 4 to 6 KHz for AM high fidelity. In addition
you will need to adjust both pass-band controls so either the upper or
lower sideband is fully in the radios pass-band.

You will void the radios warranty by having it modified.

Get an external bookshelf speaker and / or headphones will also help
the audio fidelity.

There is a Yahoo news groups devoted to this topic by the way.

Good luck with the upgrades.
