It is only as I was double-checking the Wikipedia spelling I realized that Chekov from ST is not Chekhov.

I assume that might have been the cause of error in the original post.

Russian letter "Х" (pronounced 'huh', sounds like /h/, but with more scratchiness/hiss at the back of the tongue) is traditionally transliterated into English as a digraph "Kh", due to that extra scratchiness/hiss. I personally dislike it, I think that single letter 'H' would be adequate.
Чеков does not exist as a last name in Russian. Curiously, in Russian-language Wikipedia article his name is given as Павел Чехов, the same as Антон Чехов.
