--8<---------------cut here---------------start------------->8---
* Incredible Radio Show 20:00-20:55
&%%(and 
     (and (< 0 (calendar-day-of-week date))
          (< (calendar-day-of-week date) 6))
      (diary-block 2010 3 1 2010 7 18))
--8<---------------cut here---------------end--------------->8---

The time is in the heading, you can use am/pm style too.

The "&%%(" introduces diray sexp (an elisp snippet evaluated during the
porcess of building agenda view). This one is true, which makes the
event appear, when all of following conditions ar met:

    + the day of week obtained with calendar day of week is greater than
      0 (0: sunday, 6: saturday), and less than 6.

    + the date is between 2010-03-01 (March 1) and 2010-07-18 (July 18)

Note that:

    + you have to calculate the end date by hand (maybe there is a
      function for this, but the sexp would be longer),

    + the order of numbers in diary block expression depends on the
      value of calendar-date-style variable. This one is iso style.
