I find it interesting that "live" transmission of Enemy Combatant Radio

I cannot think of rational explanation why would the signal be delayed
- maybe someone versed in FM broadcast technology can offer some ?
93.7 is San Francisco Liberation Radio (micropower license-free :-)
I'd first assumed that "Enemy Combatant Radio" was yet another variant on
National Public Communist Radio or Nationalized Propaganda Radio or
whatever :-)
If I were implementing something like non-commercial unlicensed radio,
I'd probably expect that the broadcast studio and the antennas
would not be colocated, and there'd be a need for cheap connections
between the two of them, which suggests IP over modems.
And avoiding dropouts on unidirectional connections suggests
large jitter buffers.
Two minutes seems a bit excessive, though -
perhaps there's a bit of a speed mismatch between the studio and
antenna ends of the connection that's accumulated delay,
especially if you're transmitting over TCP instead of UDP.
Speak Freely used to have this problem until some recent changes
that let it clear out buffers when they get too large.
