alternative/third party software for Icom PCR-2500
 

I'm looking for advice from anyone who has used alternative software
with an Icom PCR-2500. I currently use Icom's own contoller software
version (latest version). It's okay, but goddness me it eats into the
processor and my computer slows down as it struggles to run it. I've
seen a few things on google about alternative contoller programs but
would be grateful to hear from anyone who's actually used a good
alternative. Thanks for any advice.
