[1000mp] An optocoupled isolator for Yaesu CAT

Thu, 11 Apr 2002 08:09:19 -0700

Guido,

Thank you.

I thought that it was Orcad. I used it in the past before
I retired. My hope / wish was that it was some other similar
schematic capture but at much lower cost. Yes it is very
expensive. The evaluation version is limited.
At over $8,000 for Orcad, to much for a hobby. Now 
I use Analog Work Bench. It is 'user friendly' but as 
capable as Orcad and Pspice.

Again thanks,

73,

Mort
