CHIRP does lots of things that the radio itself cannot do . I believe that what you meant to say was that CHIRP can't make the radio do anything that the radio itself cannot do. ;-)

I do not believe the UV-5R family of radios have any way to do
split tone.

Yes. It does. Eleven different combinations (including mixed CTCSS and DCS) can be programmed and CHIRP supports them all.

One the other hand, there is NEVER any actual NEED to do split tone, because
there is NEVER any actual NEED to use a Rx Tone at all.

For those not yet understanding how CTCSS tones and DCS codes work, it is highly recommended for them to not use Rx CTCSS or Rx DCS. Setting them incorrectly will render the radio deaf. Setting both to OFF will always work.

But there are situations where having an Rx CTCSS tone or Rx DCS code programmed can be quite useful. Once the use of Rx CTCSS and Rx DCS is understood, the use of them for these situations should be encouraged.
