Surely you are joking! This question has come up many times in the last several months, and the answer is the same - there are MANY programs that support the R75. Ham Radio Deluxe, RxPlus, tk75 (if you're into the Linux world, tho it will run on Windoze), SWLog just to name a few.
If you go to either the SWL Broadcast or Utility Listening Wiki, you will find a link there for the Strong Signals software page. It will take you directly to the HF receiver support section, which will show you several links for software. Check the ones I've mentioned out, along with a couple of others I didn't....
In fact, since this question has come up so often, I wonder if a Wiki on the R75 wouldn't be appropriate. Comments?
