CAPTCHA Gotcha

I tried to send an email to an member via the contact form here. Before sending it tells you:
"CAPTCHA
We are sorry that we have to do this, but some not-so-nice spammers have started to post stuff not related to part 15 radio!"

That's ok, I don't mind. But the only problem is there is no box in which to enter a captcha in!
And when I tried hitting send anyway, it told me it couldn't send because my captcha was wrong.

So I guess the capthca is a gotcha!
