Fred,

It's been a while since I looked into the RS level converters. Another
glance yields no serious shortcoming. The only thing I can see is that a
lap-top with 5 volt serial voltages may have problems. However, if it works
for you...
I roll my own with transistors.

I wanted to use Ham Radio Deluxe with my Icom radio. It requires an CI-V
interface. Being the cheapskate that I am, I checked the internet for
"roll
your own" information.

What I found looked really familiar, turns out it is identical to an
interface I built to program my Radio Shack Pro 95 scanner. Plugged it in
and it worked just great.

This means you can purchase a RadioShack 20-289 cable for $24.99 and
replace
the high dollar CI-V if you choose not to build your own.
