It is a serious question, folks. The liturgy is composed of music, words, actions, visual things such as candles, vestments and a setting, The chancel. Not to mention the participation of those present.
Radio consists of one thing - sound.
So how does liturgy translate to radio?
What must you do to your liturgy to make it an effective thing on the radio? Do you do anything?
Squeezing it into a one hour time slot, if you have to do that, is only one thing.
I've never personally served in a church that broadcast its services. However...
1) When I was in high school, I used to listen to Trinity, Mission, KS, which broadcast every Sunday.
2) Immanuel, Higginsville, MO, also broadcast its services and I used to attend there every Sunday.
3) Redeemer, Rockford, IL, used to broadcast its early service. I preached there on occasion when the pastor was on vacation.
You listen to the liturgy. It's much like listening to a baseball, football, or basketball game. You don't get to see everything, but you get most of what's going on.
Trinity in Mission always stayed within the hour. If one of the other two churches ran long--usually due to communion--then the announcer would cut away at that time. It's not all that difficult.
