Chris,
Some of us IC-T90A oners have gotten together and put together a guide for
that little rig. You can find it on,
www.icanworkthisthing.com
under amateur radio equipment and then under handheld amateur
tranceivers. You can donload the guide from that site, or e-mail the guide
to your self. The guide is also on the Handi hams website.
Hope this helps.
